[media-caption path="/wp-content/uploads/2020/11/ODUS-Announcements-02-OS.jpg" link="#"]Ocean Decade U.S. is seeking innovative, potentially transformational, ideas about ocean science research. Honor your creativity and submit an “Ocean Shot.” Deadline is 1 December.[/media-caption]
The Ocean Observatories Initiative (OOI) has signed on as partner with the UN Decade of Ocean Science for Sustainable Development, which is geared toward scientists, policy makers, managers, and service users working together to ensure that ocean science delivers greater benefits for the ocean ecosystem and for society. OOI is part of the Ocean Decade’s Ocean Science and Technology community, making its ocean data available to the world community.
To help advance the United States involvement in the UN Decade program, OOI has also joined forces as a nexus organization with the U.S. National Committee for the Ocean Decade (Ocean Decade U.S.). The goal is to ensure that the U.S. ocean science community is aware of and participating in activities related to the UN Decade of Ocean Science.
“OOI offers a wealth of ocean data that is being used to advance understanding of ocean processes,” said John Trowbridge, lead of OOI’s program office at Woods Hole Oceanographic Institution. “We think it is important to offer this valuable resource up to the world community, and by so doing, contribute to the advancement of a sustainable ocean that benefits all users.”
Two opportunities currently exist for members of the OOI community to get involved:
Share your transformative research ideas
The Ocean Decade U.S. is seeking transformative research ideas known as “Ocean-Shots,” that draw inspiration and expertise from multiple disciplines and fundamentally advance ocean science for sustainable development. The hope is that such innovative ideas will spark potentially disruptive advances in ocean science for sustainable development. Applications are due before December 1, 2020, so the time is now to gather your colleagues together and consider proposing some innovative research ideas. To learn more, click here or if you already have a great innovative idea, use a simple online form to submit your winning idea. Submitted “Ocean Shots” will be presented at the Ocean Decade U.S. Kickoff meeting, January 13-14, 2021.
Early Career Scientist Candidates Sought
Knowing that the fate of the global ocean rests with future generations, the US National Committee for the Ocean Decade is also seeking to include early career perspectives in the activities of the Committee. Early career natural scientists, social scientists, engineers, resource managers, and policy specialists are encouraged to apply as liaisons to the Committee. Again, the application deadline is December 1, 2020. If you are looking to have a voice in what the ocean may look like in the future and how it is used, consider applying today.
Adds Trowbridge, “There is no better time than now to consider the future ocean and how it might can be sustainably used now so its many wonders and resources will be available to future generations.”
The Ocean Observatories Initiative Facilities Board (OOIFB) will host a Town Hall during the virtual 2020 Fall AGU meeting. The Town Hall is scheduled for Tuesday, December 8th from 10:00 am to 11:00 am EST. The community will have the opportunity to hear the latest information about the OOI facility, meet the OOIFB members, and learn about research using OOI data. The new OOI Data Explorer tool will be demonstrated, the exciting activities of OOI education programs will be featured, and early career scientist activities will be highlighted.
The Town Hall is aimed at researchers who are now using or are considering using OOI data, researchers interested in adding instrumentation to the OOI infrastructure, and educators at all levels interested in the OOI. Lightning talks will be presented during the Town Hall, as well as at OOI’s virtual booth on Thursday 10 December from 6-7 pm. For those interested in the Thursday presentation, join the discussion here.

[media-caption path="/wp-content/uploads/2020/11/IMG_0034-scaled.jpeg" link="#"]The Pioneer 15 Team departs aboard the R/V Neil Armstrong, framed by equipment that awaits deployment on leg two. [/media-caption]
On October 28th, ten scientists and engineers from Woods Hole Oceanographic Institution departed aboard the R/V Neil Armstrong headed to the Pioneer Array, about 75 nautical miles south of Martha’s Vineyard in the Atlantic Ocean. This trip is the 15th time that a team has traveled to the Pioneer Array to recover and deploy equipment at the site.
The team will recover and deploy three coastal surface moorings and a profiler mooring, and deploy two winter coastal profiler moorings. They will also conduct CTD (Conductivity, temperature, and depth) casts and water sampling at the deployment and recovery sites. In addition, the team will compare ship and buoy meteorological measurements at the surface mooring sites as a way to validate the mooring measurements.
“We’ve been isolating for 14 days, have successfully passed 2 COVID-19 tests, and are ready to go, “ said Sheri White, chief scientist for Pioneer 15. “This is a two-leg expedition because we can’t fit all of the moorings on the deck for one trip to the array. We plan to be in port on November 4th to swap out gear, but we can adjust our schedule accordingly. If bad weather picks up, we can head back to port early to collect the equipment for leg two and not lose valuable time at sea when we can’t work due to weather.” The ship is expected to return from leg two on 11 November.
The surface moorings being recovered have been deployed for one year – six months longer than intended, due to the COVID-19 pandemic – and so are starting to experience some wear and tear. The new moorings being deployed incorporate design updates intended to improve the robustness of components such as the wind turbines and stretch hoses. The team also will be deploying a prototype quad transducer for the ZPLSC instrument. The ZPLSC is a bio-acoustic sonar which measures acoustic signals of plankton and zooplankton at the OOI Coastal Arrays. It has transducers that emit at frequencies of 38, 125, 200 and 400 kHz (the latter three are all from a single quad-transducer). The new quad transducer design should lead to less failures and improved data collection for that instrument.
In addition to performing OOI tasks, the team will be conducting ancillary work to support the Northeast Shelf Long Term Ecological Research (NES-LTER) program. This will include CTD casts, and sampling from the ship’s underway seawater system with an Imaging FlowCytobot (IFCB) instrument.

Sheri White, WHOI, Chief Scientist
Chris Basque, WHOI, Deck Lead
Jennifer Batryn, WHOI, Instrument Lead
Collin Dobson, WHOI, Surface Mooring Lead
Meghan Donohue, WHOI, Deck Ops

The OOI’s primary mission is to make its data widely available to multiple users. One way it achieves this, on a broad scale, is by establishing partnerships with other organizations that also distribute ocean observing data. For example, OOI currently partners with the Integrated Ocean Observing System (IOOS), which provides integrated ocean information in near real-time and tools and forecasts to apply the data, the National Data Buoy Center (NDBC), which maintains a network of data collecting buoys and coastal stations as part of the National Weather Service, the Global Ocean Acidification Observing Network (GOA-ON), which uses international data to document the status and progress of ocean acidification, and Incorporated Research Institutions for Seismology (IRIS), a consortium of over 120 US universities dedicated to the operation of science facilities for the acquisition, management, and distribution of seismological data.
NANOOS: Making data relevant for decision-making
NANOOS, the Northwest Association of Networked Ocean Observing Systems, which is part of IOOS, has been operational since 2003, establishing trusting, collaborative relationships with those who use and collect ocean data in the Pacific Northwest. NANOOS has been an exemplary partner in ingesting and using OOI data. Part of its success lies in advance planning. NANOOS, for example, had determined that OOI assets, in addition to achieving the scientific goals for which they were designed, could fill a data void in IOOS assets running north and south in an area between La Push, WA, and the Columbia River, well before the OOI assets came online.[media-caption type="image" class="external" path="https://oceanobservatories.org/wp-content/uploads/2020/09/Screen-Shot-2020-09-22-at-2.25.24-PM.png" alt="Endurance Array" link="#"]OOI’s Coastal Endurance Array provides data from the north and south in an important upwelling area in the northeastern Pacific. Gliders also traverse this region, with glider data available through both the IOOS Glider Data Assembly Center and the NANOOS Visualization System.

According to Jan Newton, NANOOS executive director at the University of Washington, “One of the reasons NANOOS is so effective is that our guiding principle is to be cooperative and not compete. If the public is looking for coastal data, for example, we want to make sure they can access it and use it, rather than having them trying to sort through whether it is a product of IOOS or OOI. We operate with the philosophy of maximizing the discoverability and service of the data and OOI has been a great partner in our mission. We’ve been really happy about how this partnership has played out.”[media-caption type="image" class="external" path="https://oceanobservatories.org/wp-content/uploads/2020/09/Regional-Cable-Array-revised-.jpg" alt="Revised RCA" link="#"]OOI’s Regional Cabled Array also contributes data in the NANOOS region from its Slope Base and the Southern Hydrate Ridge nodes.

NANOOS has made a huge effort on its data visualization capabilities, so people can not only find data, but look at it in a relative way to use it for forecasting, modeling, and solving real-world problems. OOI data are integral in helping support some of these visualization and modeling efforts, which commonly play a role in situations facing a wide cross-section of society.
An example of this applicability played out in improved understanding of hypoxia (oxygen-deficient conditions) off the coast of Oregon, which had resulted in mass mortality events of hypoxia-intolerant species of invertebrates and fish, in particular, Dungeness crabs. Allowing access through NANOOS to near real-time oxygen data from OOI assets has allowed the managers and fishers to come up with some plausible solutions to maintaining this valuable resource. The Dungeness crab fishery is the most valuable single-species fishery on the U.S. West Coast, with landed values up to $250 million per year, and plays an enormous cultural role in the lives of tribal communities in the region, as well.[media-caption type="image" class="external" path="https://oceanobservatories.org/wp-content/uploads/2020/09/Dungeness-Crab.jpg" alt="Dungeness Crab" link="#"]OOI oxygen data have helped resource managers and fishers maintain the valuable Dungeness crab fishery, which is the most valuable single-species fishery on the U.S. West Coast.[/media-caption]
Researcher Samantha Siedlecki, University of Connecticut, reports that in late June of 2018, for example, fishers in the region were pulling up dead crabs in pots without knowing the cause. Scientists accessed near real-time OOI observations through the NANOOS data portal and found that the Washington Inshore Surface Mooring of the Coastal Endurance Array (EA) had measured hypoxia from June 7th onwards. So, the data confirmed real-life conditions and explained the crab mortalities.
This is important because such occurrences are helping to confirm models and enhance forecasting to better manage these events by providing guidance to fishers and resource managers. In this instance, the forecast indicates what regions will likely require reduced time for crabs to remain “soaking,” caged in the environment during hypoxia events, to ensure crabs are captured alive, and also aid in spatial management of the fishery itself. OOI data will play a role in continual improvements in forecasting in this region and the fishery by providing data during winter months, ensuring historical data are available and quality controlled for use in forecasting, and continuing to serve data in near real-time.
Adds Newton, “I can’t tell you how many OOI and other PIs come up and tell me how they love that their data are having a connection to real world problems and solutions. It makes their research go farther with greater impact by being part of this NANOOS network.”
Explains Craig Risien, Coastal Endurance Array senior technician at Oregon State University, “OOI is collecting an incredible wealth of data, offering a treasure chest of material to write papers, write proposals, include in posters, and now it is being used in practical ways for finding scientific solutions to environmental problems. Every time we look at the data, there’s a new story to tell. We always find something new, something interesting, and encourage everyone to have a look and experience the same usefulness and excitement about OOI data.”
Sharing OOI data
The OOI is in talks with the IOOS regions serving the Northeast Atlantic and the Mid-Atlantic to see how OOI data might enhance their networks, as well. The OOI also has been providing data to the National Data Buoy Center since 2016, supplementing the data collected by NDBC’s 90 buoys and 60 Coastal Marine Automated Network stations, which collectively provide critical data on unfolding weather conditions. And, the OOI has been providing data to Global Ocean Acidification Observing Network (GOA-ON), since mid-2019, ground-truthing on site conditions in real to near real-time, which is critical to understanding conditions contributing to ocean acidification and improving modeling capabilities to determine when it might occur. OOI’s Regional Cabled Array has been providing seismological, pressure and hydrophone data to Incorporated Research Institutions for Seismology (IRIS) since 2014, providing a wealth of data from Axial Seamount and on the Cascadia Margin. For example, on April 24, 2015 a seismic crisis initiated at the summit of Axial Seamount with >8,000 earthquakes occurring in 24 hrs, marking the start of the eruption. Starting at 08:01 that same day, the network recorded ~ 37,000 impulsive events delineating underwater explosions, many of which were associated with the formation of a 127 meter thick lava flow on the northern rift.
If you would like to test drive some of the OOI data in NANOOS, NDBC, and GOA-ON, here are some examples below:
· Irminger Global Irminger Array data (Station 44078)
· Regional Cabled Array (While searching within IRIS for OOI data, use the two-letter IRIS network designator “OO.”)
A team of 10 Woods Hole Oceanographic Institution scientists, who spent the month of August aboard the RV Neil Armstrong, arrived at home port in Woods Hole on 4 September, having successfully skirted Hurricane Laura as she headed in their direction. The bumpy ride home capped the successful deployment of all OOI Irminger Sea Array moorings in sometimes turbulent seas.
While onsite at the array, the team successfully met all of its mission objectives by recovering and deploying four moorings and deploying two gliders. One glider transits the individual moorings, which are spaced approximately 20 km apart, while the second glider samples the upper 200-meters of the ocean above the centrally located hybrid profiler mooring, which measures the remainder of the 2800-m water column. A third glider was recovered soon after deployment because it had a microleak. The team also conducted CTD casts at each of the moorings, which measure onsite temperature, salinity, and oxygen conditions and validate data being collected and sent to shore by the array.
“The Irminger Sea array presents both unique opportunities and challenges for reporting ocean data,“ explained Sebastien Bigorre, who served as chief scientist on the Irminger Seven expedition. “It is located in a remote area of the North Atlantic with high wind and large surface waves, which present operational challenges. The area is also of great interest for scientists and society because of the intense exchange of energy and gases between the atmosphere and the ocean. The ocean there captures heat and carbon dioxide from the atmosphere, thus it is an important component of the climate system. It is also a region of high biological productivity, making it an important fishery. Recent studies have shown that the data collected at the Irminger array are essential to correctly describe the ocean circulation of the North Atlantic.”
It is an eight-day transit from Woods Hole to the Irminger Sea Array and another eight-day transit to return to home port. To maximize the use of ship time, the Irminger Sea Array Team shared ship space and mission time with scientists from OSNAP (Overturning of the Subpolar North Atlantic Program). OSNAP is seeking to provide a continuous record of the horizontal transport of heat, mass, and freshwater in the subpolar North Atlantic, and is complemented by the much longer-term records of water-column properties and air-sea transfer of momentum, heat, and moisture that are provided by the OOI Irminger Sea Array. Once on site, the expedition started with deployment of OOI moorings and gliders, switched its focus to recovery and re-deployment of OSNAP moorings, before finishing with the recovery of the previous year OOI Irminger Sea moorings.
“Our partnership with OSNAP is an example of how we try to maximize our resources for scientific research, from cruise planning, to operations at sea. During transits, we test and triple check our equipment to ensure that comes deployment day, everything goes as smooth as possible. On site, we coordinate operations to accommodate for weather conditions or to optimize shared equipment or personnel. When there is a lull in scientific activities, we plan for the ship’s instrumentation to collect data that is relevant to our scientific objectives, so every hour of the cruise is used to its full potential,” added Bigorre.

The Endurance Array team at Oregon State University (OSU) achieved a first in early August. They succeeded in recovering a Coastal Surface Piercing Profiler (CSPP) and its anchor from the Oregon Shelf site with an ROV customized for this endeavor.
The team boarded the 54-foot R/V Elakha, which is owned and operated by Oregon State University on Thursday 5 August, to implement a recovery scheme developed by OSU-OOI technicians Alex Wick and Ian Black.
Wick and Black also created and configured the line pack and other materials needed by the ROV, and led operations on deck. Jeremy Fox, captain of the R/V Oceanus, operated the ROV. The goal was to retrieve the orphaned CSPP from the site.
“This successful mission demonstrates the creativity and determination of the Endurance Array team to retrieve equipment from the seafloor,” said Jonathan Fram, project manager for the Endurance Team Array at OSU. “When we lose a piece of equipment, we do everything in our power to retrieve it not only because of the expense of the equipment and the scientific value of data it contains, but because we are required to recover what we deploy. OSU-OOI has recovered orphaned equipment with ROVs in the past, but the recovery scheme used here was much more effective and efficient.”
The mission is shown in the pictures below:[media-caption type="image" class="external" path="https://oceanobservatories.org/wp-content/uploads/2020/08/Elakha.jpg" alt="Elakha" link="#"]OSU’s 54″ R/V Elakha, the Chinook trading language word for sea otter, is powered by a single, 600-horsepower diesel engine with a range of about 575 miles.

Ten scientists from Woods Hole Oceanographic Institution (WHOI) will board the R/V Neil Armstrong on 8 August 2020 for about a month-long expedition to OOI’s Irminger Sea Array. The journey includes an eight-day transit to reach the array, where they will recover and replace ocean observing equipment that has ridden out arduous conditions in a region known for intense winter wind events (peak speeds of 50-55 knots).[media-caption path ="https://oceanobservatories.org/wp-content/uploads/2020/08/Irminger-Deck-Plan-small-scaled.jpg" link="#" title="Iminger Deck] Aerial view of the R/VNeil Armstrong deck with equipment loaded for an OOI Irminger Sea Array service cruise.

Iceland is separated from the east coast of Greenland by the Denmark Strait, roughly a distance of some 250 miles. The Irminger Sea is south of the strait, stretching from Iceland down to the latitude of Cape Farewell at Greenland’s southern tip. This region is important to the Atlantic Ocean circulation and sensitive to global climate change.
Supported by wind power and solar cells, the Irminger Sea Array consists of moorings that serve as home for sensors that measure air-sea fluxes of heat, moisture and momentum, and physical, biological and chemical properties throughout the water column. The observations of the moorings are enhanced by open-ocean gliders that sample within and around the triangular array. The subsurface mooring data is also collected by the gliders via acoustic modem. The gliders then relay the collected data, glider sampling and mooring data, to shore via satellite telemetry each time they surface. Gliders also sample the upper water column near the Apex Profiler Mooring to complement the moored profiler data and extend coverage to the air-sea interface.
This month-long expedition is the seventh time the OOI team has traveled to the array, specifically to replace and repair equipment that is vital to maintaining a continuous flow of data from this important site.
“This is a difficult region to sustain surface observations, yet such observations are critical to improving our understanding of air-sea exchanges and deep convection that drives the Atlantic overturning circulation” said Al Plueddemann, project scientist for the OOI Coastal and Global Scale Nodes (CGSN).
WHOI Research Scientist Sebastien Bigorre will serve as the chief scientist for the expedition.
The scientific party went into a 14-day quarantine on 21 July to ensure that everyone could safely board the ship. They were tested for COVID-19 prior to quarantine and will be tested again prior to departure. Masks and social distancing will be practiced onboard until another two-week period of health is achieved. At that point, mask wearing may be loosened as the scientific team and crew members will, in effect, be their own social bubble as they live, work, and share the space of the 238 foot-long vessel.[media-caption path="https://oceanobservatories.org/wp-content/uploads/2020/08/DSC_0016_allison-scaled.jpeg" link="#" title="crew deploys a near surface instrument frame to the array"]During a past expedition to the Irminger Sea Array, the crew deploys a near surface instrument frame to the array.

Explained Derek Buffitt, program manager for the Coastal and Global Scale Nodes, operated from Woods Hole Oceanographic Institution, which includes oversight of the Irminger Sea Array, “COVID-19 created plenty of new logistical challenges for an expedition of this length and distance. We had to address contingencies such as what to do if someone presented COVID symptoms while at sea. WHOI’s marine operations office, working with agents and government representatives, confirmed health and safety protocols within the foreign ports along the planned vessel track. This was to ensure our personnel could receive the care needed in an emergency and in a timely manner.”
Such contingencies were necessary steps, in addition to many months of preparation, to ensure the equipment to be deployed is ready, tested, and packaged for transporting to the ship.

The University of Washington (UW) Regional Cabled Array (RCA) team entered a two-week quarantine period on 16 July before heading out to sea August 1, aboard the UW global class research ship the R/V Thomas G. Thompson for a month-long expedition in the northeastern Pacific. The expedition is funded by the National Science Foundation as part of the Ocean Observatories Initiative. The team will need whatever rest they can muster during the quarantine, as the expedition promises to be replete with round-the-clock activity, including multiple dives a day by the remotely operated vehicle (ROV) Jason.
During this expedition, the team will recover and reinstall more than 200 instruments with the ROV, while broadcasting livestream video from the ROV Jason to the ship, to a satellite over 22,000 miles above the Earth. From space, the video will then be transmitted to the UW, where it will be publicly available on the UW InteractiveOceans website. A daily blog will provide updates on the expeditions progress. Throughout the month, viewers will witness life thriving at depths 2900 m (>9500 ft) beneath the ocean surface and at Axial Seamount, the most active submarine volcano off the coast of Oregon and Washington.[media-caption type="image" path="https://oceanobservatories.org/wp-content/uploads/2020/07/Control-room-_Jason_Hell_-Vent-scaled.jpg" link="#"] An example of some of the stunning imagery that will be live-streamed during the RCA expedition.

The RCA consists of 900 kilometers of cable that provide high-power, bandwidth, and two-way communication to 150 scientific instruments on the seafloor and to state-of-the art instrumented moorings that relay a constant stream of real-time ocean data to shore, 24 hours 365 days a year. All data are freely available to the community.
Being in corrosive saltwater for a 12-month stint is a hostile environment for equipment, so every summer a team of UW scientists and engineers head out to the array to recover equipment and deploy replacement ocean observing instrumentation These recovery and redeployment missions ensure that data continuously flow to shore from this Internet-connected array. At the RCA, cabled instruments are located across the Cascadia Margin, the Southern Hydrate Ridge, and at Axial seamount, each making an important contribution to better understanding the subseafloor environment. Cascadia Margin is one of the most biologically productive areas in the global ocean. Explosions of methane-rich bubbles issuing from beneath the seafloor rise > 1000 feet into the overlying water column at Southern Hydrate Ridge. Axial seamount has erupted in 1998, 2011, and 2015 and hosts some of the most extreme environments on Earth—underwater hot springs venting fluids at >700°C.
Dr. Orest Kawka, an RCA Senior Research Scientist, and Brendan Philip from the UW will sail as Chief Scientists – directing the cruise during the four weeks at sea. As an undergraduate, Philip sailed on numerous RCA cruises as part of the UW educational VISIONS at sea experiential learning program, which has taken over 160 undergraduate students to sea, and later as a member of the RCA team. He is now pursuing a master’s degree in Technology, Science, and Policy at George Washington University in Washington, DC.
Because of the large amount of gear (over 80,000 pounds of equipment) to load onto the fantail of the Thompson for deployment, the cruise will consist of two legs.[media-caption type="image" path="https://oceanobservatories.org/wp-content/uploads/2020/07/RCA-Jason-manipulator-with-sea-anemones.jpg" link="#"]The manipulator arm of the ROV Jason operates in front of an anemone-covered junction box in the highly productive waters at the Oregon Shelf site.

During more than 30 Jason missions to the deep, viewers will witness parts of the ocean rarely seen by humans. The team hopes to revisit some of the scientific highlights of last year’s expedition. One such highlight was Jason being investigated by a swarm of large sable fish. At another site at 80 meters, a junction box became an island completely encrusted in beautiful sea anemones. At Southern Hydrate Ridge, the team saw rarely seen exposed methane hydrate and a moonscape topography dramatically changed from the year before, marked by new explosion pits and collapsed areas. And, on many past expeditions, team members have seen a novel prehistoric-looking fish, which was first filmed in the ocean on the 2014 RCA cruise at the Slope Base site at a depth of 9500 ft. The RCA team fondly refers to this creature as “the weird fish,” (Genioliparis ferox), which also has been documented off Antarctica.
“We’ve got a fantastic team sailing this year, who have been putting in an incredible amount of work for months to get us ready. But like all cruises sailing this year, we’re dealing with the necessary challenge of having a smaller science party and still making sure we can safely accomplish the science and recovery and deployments. We will be in constant communication with the rest of the team back on shore, who will contribute as much to getting our work done as will the science party on the ship. The RCA team is grateful for the opportunity to sail during what has turned out to be a challenging year for ocean science and we’re looking forward to helping other oceanographers continue their research, even if they’re unable to sail this year,” said Chief Scientist Brendan Philip.[media-caption type="image" path="https://oceanobservatories.org/wp-content/uploads/2020/07/FACT_Cage-scaled.jpg" link="#"]Manipulators on the ROV Jason work on a small frame located ~ 200 m beneath the oceans’s surface, which is encrusted in beautiful feathery creatures called crinoids.

The Daily Grind
The daily schedule aboard the R/V Thompson promises to be intense, exacerbated by a smaller than normal scientific party due to COVID-19 precautions. “Science teams, when using Jason, tend to keep the vehicle down for a long time, but because the tempo of this cruise is more like an industry cruise, the team will be diving and recovering the vehicle as rapidly as safely possible, sometimes with only a couple hours on deck between dives. It can be exhausting work, particularly for a team that will be onboard for a month,” explained Deb Kelley, RCA Director and principal investigator. “But, being out at sea, seeing the sites and miles of ocean reaching the horizon, and working on this state-of-the-art marine facility makes it all worthwhile.” This year, for the first time, Kelley will be intently observing operations from onshore through the live video stream.
A reality in the new COVID-19 world is that the team can only mobilize gear onboard the ship after completing a strict quarantine period. Two weeks prior to boarding, members of the scientific party have lived in their homes (with all family members in quarantine for the duration), hotels or Airbnbs. Team members were tested for COVID prior to entering quarantine and conducted twice day temperature checks during their quarantine. Testing occurred again before being allowed to board the Thompson.
This expedition is novel in another way as a result of COVID precautions. Only two students will be onboard. Prior cruises have had 8-10 VISIONS students on each leg to help out and experience firsthand what it’s like to go to sea. “We are hoping that many students and others tune in to experience this amazing environment that Jason will be revealing over the next month. It’s really an opportunity to visit some of the most extreme environments on Earth and see incredible life forms that has adapted to these harsh environments, which may be particularly uplifting to our spirits now that many folks are stuck at home,” said Kelley.Read More
