Potential Relocation of the OOI Pioneer Array Discussion 8 Dec
The National Science Foundation (NSF) will present plans to use an “Ideas Lab”, a participatory, immersive process designed to innovative the decision-making process for the potential move of the Ocean Observatories Initiative (OOI) Pioneer Array at the American Geophysical Union Fall Meeting. The presentation will be at the OOI virtual booth, on 8 December 11:15-noon Eastern. Lisa Clough, Section Head from NSF’s Division of Ocean Sciences, will describe the “Ideas Lab” process that will be used to determine if the Pioneer Array should be moved, and if so, to what location. She will be joined by Al Plueddemann, Project Scientist for OOI’s Coastal and Global Scale Nodes, who will speak to the operational considerations involved in a potential move of the Pioneer Array.
The Coastal Pioneer Array is currently located in the Middle Atlantic Bight, centered about 75 nautical miles south of Martha’s Vineyard, where the continental shelf-slope is highly productive. The area was chosen as the initial placement of the Pioneer Array to examine exchanges between the shelf and slope and the shelf ecosystem and provide insight into air-sea gas exchange, including carbon dioxide absorption. From the outset, NSF has committed to re-evaluating the placement of the Pioneer Array every five-to-seven years.
“Ideas Lab are designed to bring together people to innovate and invigorate their scientific and educational approaches. We hope by using this participatory process, current and future users of OOI data will deeply explore the opportunities of having an open-data real-time coastal ocean array in various locations within the US EEZ,” explained Clough. “It is our hope that by collectively considering what the optimal location for the Pioneer Array is, and to a certain extent what types of data will be collected and how, the decision-making process will also encourage new thinking.”
Plueddemann, who has been involved with 15 successful missions to recover and deploy equipment at the Pioneer Array, will introduce some of the technological, logistical and environmental considerations inherent in a decision to relocate the array.
“My role in this decision-making process is solely as an information broker,” explained Plueddemann. “Neither I nor anyone involved in the current Pioneer Array team will be involved in the process of deciding how and where the Pioneer Array might be relocated. Our role will be to inform and advise on the feasibility of different concepts.”
Regardless of the location decision, the current team at Woods Hole Oceanographic Institution will continue to operate the Pioneer Array. Their formal role as operators of the Array entails expertise in the deployment, recovery, and maintenance of the equipment.

OOI Links Up with U.S. National Committee for the Ocean Decade
[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.”

Rolling Seas, Followed by Blue Skies During Pioneer 15
The weather for the 15-day Pioneer 15 expedition aboard the R/V Neil Armstrong came in like a lion and left like a lamb. As the ship departed the Woods Hole dock on 28 October, the sky was gray, the air damp, and the forecast foreboding as the 10- member scientific team and the crew of the R/V Neil Armstrong headed toward the Pioneer Array, about 75 nautical miles south of Martha’s Vineyard.
During Leg 1, the ship had some rocky days and briefly sought the protection of Menemsha Bight on the northwest side of Martha’s Vineyard as Tropical Storm Zeta passed through and brought her fury with her. Leg 2 of the journey brought with it clear skies and smooth sailing. The following shows the wind and pressure data from the ship throughout the Pioneer 15 cruise.

Chief Scientist Sheri N. White said, “Despite the difficult weather, we had a very successful mission. The team recovered and deployed three coastal surface moorings and a profiler mooring, and deployed two winter coastal profiler moorings. We also were able to recover three gliders, and collect shipboard and CTD data in the vicinity of the Array. We planned on a bit of flexibility in the schedule due to the late fall departure, which always brings with it unpredictable conditions.”
The expedition was conducted in two legs because all of the moorings could not be accommodated on the ship at the same time. The Team returned to home port at the conclusion of the cruise on 11 November, when they disembarked after a month of being either in isolation or at sea away from friends and family.
The recovered moorings are now undergoing refurbishment onsite at WHOI so they will be ready for the next equipment turn in spring 2021. Next on tap for the Pioneer Array is the deployment of four gliders, Next on tap for the Pioneer Array is the deployment of four gliders, which will be done from a small vessel when the weather allows a safe transit.

Pioneer 15 Underway
[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.

OOI Irminger Sea Data Helping Fill Critical Gap in Climate Models
Researchers at Woods Hole Oceanographic Institution (WHOI) were recently awarded a $500,000 grant from the National Oceanic and Atmospheric Administration’s (NOAA) Climate Observations and Monitoring (COM) program to develop machine learning tools to improve estimates of air-sea heat exchange in the Arctic Ocean and adjacent seas. These tools are expected to fill critical gaps in climate models, which currently show large disparities when simulating the rate of polar ice melt.
Recent advances in remote sensing technologies have provided researchers with the data they need to better understand the forces behind Arctic ice melt and the implications of that heat exchange between the ocean and the atmosphere. These real-world measurements will allow researchers to develop algorithms that will validate and improve satellite-based modeling of the Arctic and subarctic regions.
Due to the difficulty of accessing the Arctic Ocean—especially during the stormy winter months—and the complexity of measuring air-sea heat exchanges, there has previously not been enough quality data to incorporate ice melt and seasonal changes into climate models. This challenge was overcome by recent advances in long-term remote data collection at high latitudes. For the first time in 2019, an Ocean Observatories Initiative (OOI) surface buoy in the Irminger Sea collected over a year’s worth of sensor data, including icy and windy winter conditions. Located in an important area of ocean circulation, the data collected from the OOI surface buoy provides critical verification for satellite-based models.
Lisan Yu, a WHOI senior scientist and the project’s principal investigator, said a machine learning-based framework will improve the accuracy of ocean-surface forcing estimates used to model the global climate. She said it will also improve the accuracy of ice and weather forecasts in a region that is rapidly opening up to commercial exploration. WHOI Senior Scientist Al Plueddemann, who also serves as a co-principal investigator for OOI and project lead for its Coastal and Global Nodes, is a collaborator on this project.
