OOI Participates in Woods Hole Science Stroll
The Woods Hole Science Stroll is an annual event that highlights the major research institutions located in Woods Hole village (WHOI, MBL, NOAA, USGS, USCG), and also includes over 20 organizations representing a breadth of STEM research, education, and environmental groups (Fig 1). The all-day event is open to the public and includes exhibits and hands-on demonstrations for visitors to learn about marine science directly from working scientists, engineers, and technicians. Exhibits range from explanations of ocean science and environmental stewardship to demonstrations of underwater robots and aerial drones.
The OOI team participated in the 2026 Science Stroll, which took place on August 8th and hosted over 2,500 visitors. The Stroll is an effective form of public outreach, allowing OOI engineers and technicians to explain the project’s science goals and observing technology directly to visitors. OOI team members participated in planning, preparation, and staffing of the event and prepared two exhibits.
The first exhibit showed examples of OOI instrumentation, including a CTD, fluorometer, and nitrate sensor (Fig. 2). In addition to seeing the size, shape, and sensing mechanisms of real instruments, the exhibit also had several of the same instruments that had been damaged, either by impacts during deployment and recovery or by falling to the seafloor and being crushed by pressure.
The second exhibit presented OOIs Remotely Operated Vehicle. The ROV is used for visual inspection of mooring components after deployment and assessment or recovery of assets that cannot be retrieved by other means. Seeing an ROV up close gives visitors a sense of its size, weight, and layout and leads to many questions. Examples include why there are four thrusters, how weight and buoyancy are balanced, and why the camera has to be pointed towards the manipulator.
The OOI exhibits were adjacent to WHOI’s mooring and rigging shop display, allowing discussions of mooring materials to be demonstrated with samples of synthetic line, shackles, wire rope, and other components. The rigging shop display included a 64-inch syntactic foam flotation sphere used for subsurface moorings.
To one side of the OOI exhibit tables was an OOI Coastal Profiler Mooring buoy, demonstrating the size and scale of what can be seen from a ship in the vicinity of an OOI array. On the other side was a foam flotation sphere that exceeded its depth rating and was destroyed by high pressure (Fig. 3). The crushed sphere is a crowd favorite, which visitors are free to touch and inspect up close.
With thousands of potential interactions between scientists and members of the public, the Science Stroll offers a unique venue for telling the OOI story in the context of the world-class ocean science being conducted in Woods Hole village.

Read More NSF Seeks Community Input on Future Ocean Observing Priorities
The U.S. National Science Foundation (NSF) has issued a Dear Colleague Letter (DCL) seeking input from the ocean science community on future ocean observing priorities. The DCL provides an opportunity for the community to share perspectives on the future of NSF-supported ocean observing. NSF is asking about observing gaps, fixed and mobile assets, new technologies, coordination with other programs, operational uses and stakeholders, measures of value, and which elements of its existing observing portfolio should be maintained or updated.
OOI has now been operating for more than a decade, providing openly available multidisciplinary data across a range of ocean environments. The program was designed around an anticipated 30-year operating life, with infrastructure that is reconfigurable, extensible, and relocatable so that arrays, instruments, and platforms can move and change as science priorities and technologies evolve. The relocation of the Pioneer Array from the New England Shelf to the Mid-Atlantic Bight, following NSF and community workshops, is one example.
OOI combines sustained observations from instrumented moorings with the spatial coverage provided by autonomous platforms and supports the incorporation of new sensors and observing technologies. In addition to the observing assets and long-term data records, OOI now has more than a decade of experience deploying, operating, maintaining, and modifying a sustained ocean observing system.
Those who use OOI data, assets, or capabilities can bring their experience to the broader discussion by telling NSF what has worked, what should continue or change, and how OOI can help address future ocean observing priorities.
OOI encourages researchers, educators, students, data users, technology developers, partner organizations, and other stakeholders to review the DCL and provide input directly to NSF.
Responses may be submitted by individuals or as aggregated responses from groups or organizations and are due September 30, 2026.

OOI User Accounts Coming for Data Access
The U.S. National Science Foundation Ocean Observatories Initiative (OOI) plans to introduce user accounts for access to OOI data. OOI data will remain free and available to anyone who creates an account. No subscription, institutional affiliation or payment will be required. The change is intended to improve service to users, support reliable data access, and give OOI a better understanding of how the observatory is being used.
OOI will announce the implementation date and provide instructions before login is required. No action is needed now.
Why OOI is introducing user accounts
OOI serves a broad community of researchers, educators, students, government agencies, private organizations, and other users. Most data access today is anonymous, which means OOI has limited information about who is using the data, which services are most useful, and where improvements would have the greatest value.
User accounts will provide clearer information about how OOI data and services are used. This will help OOI make better decisions about data tools, documentation, training, and user support. It will also improve our ability to describe the use and impact of this research facility, funded by the U.S. National Science Foundation.
Authentication will also help OOI manage automated traffic and protect system performance. Many users rely on scripts, APIs, and other automated workflows, and those uses will continue to be supported.
What users can expect
- Better support and documentation. A better understanding of the user community will help OOI focus tutorials, examples, training, and support where they are most needed.
- More reliable data access. Authentication will help OOI distinguish normal research activity from unusually intensive automated traffic that can affect system performance.
- Continued support for automated workflows. OOI will provide guidance for users who access data through APIs, scripts, and other automated systems.
- Better information for future improvements. Usage information will help OOI identify which data products and services are most important to the community.
- A clearer picture of OOI impact. Better information about research, education, government, operational, and commercial use will help OOI and the U.S. National Science Foundation understand how the observatory is serving the community.
What will not change
OOI data will remain free and available to all users who create an account. The account requirement will not introduce a subscription or fee, nor will users need to be affiliated with a particular institution or organization to access OOI data.
OOI will provide advance notice before login is required, including instructions for creating an account and for updating automated data-access workflows. Additional information will also clarify which OOI data services require authentication and what information users will need to provide when creating an account.
Information collected through accounts and data access will be used to understand and improve use of the observatory and support reporting on OOI use and impact. Before login is required, OOI will provide information explaining what account and usage information will be collected, how it will be used, and how it will be protected.
What users need to do
Nothing yet. OOI will provide the implementation date, account-creation instructions, and technical guidance before the new requirement takes effect. Users who access OOI data through scripts, APIs, or other automated workflows will also receive guidance on any changes needed to maintain access.
User accounts will help OOI understand the community it serves and improve the reliability and usefulness of its data services.
Users with questions can contact the OOI HelpDesk.
Read MoreIFCB Webinar #2 Highlights: Lessons from Time/Moored-Based IFCB Observations
The second webinar in the Ocean Observatories Initiative Facility Board (OOIFB) four-part IFCB webinar series focused on time/moored-based Imaging FlowCytobot (IFCB) deployments and the challenges of operating IFCBs on sustained ocean observing platforms.
The webinar speakers were Kylene Cooley, Woods Hole Oceanographic Institution (WHOI), who leads IFCB operations for the OOI Pioneer Mid-Atlantic Bight (MAB) Array, and Kasia Kenitz, Southern California Coastal Ocean Observing System, who discussed IFCB operations on the Del Mar Mooring in the California IFCB Network. Both shared practical lessons from deploying and maintaining IFCBs in long-term, moored observing systems.
Cooley shared lessons from deploying IFCBs on the Pioneer MAB Array, where the instruments operate for extended periods with limited physical access and satellite communications. She discussed the importance of preparing and testing the IFCB before deployment, including pressure and power testing, instrument burn-in, automatic startup configuration, and coordination with the mooring team. She also described challenges encountered during deployments, including biofouling, power supply issues, instrument alignment, and weather conditions that can limit access to the moorings.
Kenitz described IFCB operations on the Del Mar Mooring, where the instrument is solar-powered and uses cellular communications for near-real-time data transfer and remote monitoring. Increased solar capacity has allowed the IFCB to sample more frequently, moving from every three to four hours to every one to two hours. She also discussed challenges with operating the IFCB alongside other sensors, including mechanical pump noise that can interfere with velocity measurements. Both presentations highlighted the importance of routine cleaning, antifouling measures, remote monitoring, and pre-deployment testing for long-term IFCB deployments.
The remaining webinars in the series will focus on space/ship-based IFCBs and experiments and lab-based studies. To learn more, view webinar recordings, and find upcoming dates, visit the OOIFB webpage.

Read MoreAMOC Heat Transport from Reanalyses
(Adapted from Winkelbauer et al., 2026)
Oceanic heat transport is important for understanding the Atlantic Meridional Overturning Circulation (AMOC), and ocean reanalysis models provide a means of evaluating transport variability and trends. A recent paper by Winkelbauer et al. (2026) evaluated the extent to which reanalyses reproduce transports estimated from observations. Their results show that the reanalyses capture the overall character of heat transport in the subpolar North Atlantic, but have limitations in particular times and regions.
The authors used observations from the Overturning in the Subpolar North Atlantic Program (OSNAP) data set compiled by Fu et. al. (2023), which includes both OSNAP-West (Labrador Shelf to West Greenland) and OSNAP-East (East Greenland to Scotland). The OSNAP-East array incorporates the OOI Irminger Sea Flanking moorings. The observation-based transport estimates were compared to those from several reanalysis models. A composite (mean) product was produced from four models with ¼ degree resolution that are based on the Copernicus Marine Service Global Reanalysis Ensemble Product (GREP). A higher resolution product, the Global Ocean Reanalysis System (GLORYS12V1) was also used in the comparison. All of the reanalyses are based on Nucleus for European Modeling for the Ocean (NEMO). It is notable that none of the reanalyses assimilate ocean velocity observations. This means that ocean transports differences will depend largely on velocity differences between observations and models.
Comparisons during the OSNAP observation period (2015-2020) include temperature, velocity and transport. Temperatures are relatively well reproduced by the reanalysis models, albeit with some systematic biases – cold biases in the basin interiors and warm biases on the shelves. The broad structure of ocean currents can be seen in the models, but there are discrepancies in both strength and location of the Labrador Current, West Greenland Current and East Greenland Current. However, it is also noted that limited observations in a few key regions compromise comparisons there. For transport, the reanalyses capture overall variability, and most are well correlated with observations over the ~6 year period (Fig. 3). However, none of the reanalyses capture the 2015 transport peak observed by OSNAP.
The authors dig deeper into the 2015 transport discrepancy and find that it is associated with a region of the OSNAP line near the Iceland and Rockall-Hatton Basins where glider transects supplemented the moored array in the upper ocean. They speculate that changes in the observational coverage due to gliders contribute to the 2015 transport peak that is not captured by the models.
Overall, this comparison study is a relatively strong endorsement of the reanalysis models, which “generally reproduce the broad structure of the AMOC and its associate heat transport”, although not without bias (5-10% in the mean and 60-80% for some times and locations). In addition, some key boundary currents are not well represented in the models. Interestingly, the case study for 2015 shows that the OSNAP moored array also has limitations, and can be improved by the use of gliders to resolve upper-ocean structure between mooring stations.

Read MoreEffects of Dissolved Oxygen and Hypoxia on Catch Rates of Nearshore Groundfishes in a Recreational Hook and Line Fishery
Rasmuson et al. (2026) investigate the impact of hypoxic events on a nearshore, multispecies recreational groundfish fishery along the Oregon coast. Using dissolved oxygen (DO) data from the National Science Foundation’s Ocean Observatories Initiative (OOI) Oregon Inshore Mooring (2018–2022, excluding 2020) and trip-level recreational fishery catch data from the Oregon Department of Fish and Wildlife, they modeled catch-per-unit-effort (CPUE) and species encounter rates as functions of DO and regulatory bag limits. Of the 709 days analyzed, 36.8% were characterized as hypoxic (DO < 61 μmol/kg). Of the 4 years, 2021 had the most severe hypoxia and 2019 had the least. Across all trips, CPUE and average number of species encountered generally declined during hypoxic periods, indicating reduced fishing success. However, species-specific responses varied: some, such as blue/deacon and China rockfish (see Fig. 2), showed increased CPUE with higher DO levels, while others like cabezon and quillback rockfish were more frequently caught during hypoxic events. These patterns suggest that hypoxia alters species’ availability and/or catchability, possibly due to shifts in fish behavior, vertical distribution, or tolerance to low DO. Notably, species with increased CPUE under hypoxia are already considered vulnerable or limiting for the Oregon recreational fishery, raising concerns about increased pressure on sensitive stocks. As hypoxic events become more frequent with climate change, incorporating DO metrics into stock assessments and fisheries management would improve population models for exploited species. Their findings highlight the need for fine-scale, species-specific approaches to recreational fisheries management in the context of changing ocean conditions and suggest that recreational fishers may face constraints in adapting to deoxygenation, especially in strongly place-based or single-species fisheries.

Read MoreHelp Us Solve a Mystery of the Deep
We would like the community’s help in deciphering an unusual “blow down” event impacting environmental conditions near the flank of Axial Seamount (summit depth ~1500 m), located 300 miles offshore Oregon (Figure 1a). A blow down and its impacts were recorded by numerous instruments streaming data back to shore in real time from the Axial Base Shallow Profiler Mooring. The mooring is one of three two-legged moorings on the RCA that include a mechanical anchored leg and a second anchored leg consisting of an Electrical-Optical-Mechanical (EOM) cable supplying power and two-way communications (anchors at ~ 2600 m). Both legs attach to an ~ 3.7 m across central float at ~ 200 m water depth providing 900 Kg buoyancy that pulls on the legs (Figure 1b). The float contains a static platform hosting 8 instruments and a winched science pod with 10 instruments, that conducts a daily science mission of 9 profiles spanning 200 m to ~ 5 m beneath the surface, depending on overlying seastate (see McRae, 2016). For seven of the profiles, the pod ascends at 5 cm/sec and descends at 10 cm/sec. In total, Two profiles are stepped and include 5-minute stops on descent.
The event started April 8, 2026, lasting until April 12, 2026. It was marked by a staggered increase in pressure (depth) closely related to tides, with a mean current of ~ 30 cm sec toward the NE, which blew the platform down almost 40 meters on April 24th (Figure 1c). The water mass included lower dissolved oxygen concentrations and a decrease in pH. Could this reflect an internal wave with tidal forcing? (M. Muglia, pers comm). Over the 12 years of nearly constant monitoring at Axial Base, this is the first time we have witnessed such an event. Several blowdowns have been documented at the Oregon Slope Base and Offshore Shallow Profiler Moorings, but never with the “sawtooth” changes in pressure.

Read MoreOOI Team Helps Capture Historic Shipwrecks in 3D
Almost any oceanographic expedition includes a group who disappear soon after departure to become “night stalkers.” These are the people who reverse their circadian rhythm, miss regular meals, and divorce themselves from the daytime pulse of activity to staff the night shift. They often develop a unique culture full of shorthand that only they fully understand.
On the Heroic Age Expedition to map and explore the wrecks of ships connected to Ernest Shackleton and Robert FalconScott, that role fell primarily to a three-person team from the U.S. National Science Foundation (NSF) Ocean Observatories Initiative (OOI). They were operating an OOI-provided, NSF-funded Falcon remotely operated vehicle (ROV) outfitted with a Voyis photogrammetric stereo camera system, as well as an ultra-high definition video camera, forward-looking sonar, and acoustic tracking beacons. The stereo camera allowed the OOI team to meet one of the major objectives of the expedition: fully documenting the shipwrecks and surrounding seafloor in three dimensions.
The Falcon ROV is typically used to inspect, maintain, and recover OOI seafloor observatory infrastructure, making this expedition a unique opportunity to demonstrate how OOI’s advanced capabilities can also support underwater archeological exploration and other scientific discoveries beyond routine observatory operations.
For much of the expedition, which was organized by Woods Hole Oceanographic Institution (WHOI) and the Royal Canadian Geographical Society (RCGS), while most of the science party slept, the OOI team of Andy Robinson, James Kuo, and Sam Dahlberg went to work. Their shift began after the human-occupied submersible Alvin had been safely stowed for the night. From a control station in the Hydro Lab aboard the Office of Naval Research’s R/V Atlantis packed with monitors, they guided the compact ROV through painstaking survey patterns, often just a few feet from the wrecks and the life that flourished on and around them.
“The lack of prior knowledge of the wrecks, especially Quest, where we only had a single sidescan sonar image, was a challenge,” said Robinson, chief pilot of the ROV. “We had to always be mindful of our exits. It was very different from our usual missions inspecting and recovering seafloor instrumentation.”
The targets that the Royal Canadian Geographical Society picked were two iconic vessels from the Heroic Age of Antarctic exploration. The first was Quest, the ship used by Shackleton on his final expedition and the vessel on which he died in 1922. The second was Terra Nova, which carried Robert Falcon Scott to Antarctica on his ill-fated South Pole expedition.
During each dive, the Voyis system captured hundreds of thousands of overlapping stereo photographs. Those images will be stitched together using a photogrammetric processing technique known as simultaneous localization and mapping (SLAM) to produce highly detailed digital reconstructions of the wrecks and surrounding seafloor. Every deck beam, broken spar, and scattered artifact will become part of a virtual model that researchers will be able examine long after the expedition.
“The imagery and data we collected from the wrecks in such a relatively short period is staggering,” said shipwreck expert and co-chief scientist of the expedition David Mearns. “A major question for me in the planning was whether we’d be able to get total coverage of both wrecks, documenting every surface of their exteriors and exposed interiors, knowing that the key to understanding a badly damaged shipwreck would be to have a single coherent, photogrammetrically accurate image as a final product. That question has been answered without reservation, and I can’t wait for the day the RCGS reveals what we have uncovered.”
The contribution of the OOI team extended well beyond operating the vehicle. They served as deckhands, deploying and recovering the ROV and the other half of the two-body vehicle system—a towcam provided by the NSF-funded WHOI Multidisciplinary Instrumentation in Support of Oceanography (MISO) Facility. They also acted as navigators, vehicle mechanics, camera technicians, and, along with imaging specialist Zoe Daheron, data managers and quality-control experts, continuously reviewing imagery and adjusting survey plans to ensure complete coverage.
By the time the ship returned to port, the night stalkers had accomplished something remarkable. Through the combined capabilities of the vehicle and camera systems, Quest and Terra Nova have been documented, transforming two historic wrecks from distant archaeological sites into immersive digital records that scientists, historians, and the public will be able to explore.
