Ocean Observatories Initiative

Reminder: Application Deadline Tomorrow – Tuesday, March 18th A final reminder for those interested in the 2025 National Science Foundation Ocean Observatories Initiative Facility Board Summer School on Acoustics - applications close tomorrow at 11:59 PM ET. This week-long, in-person program (July 14-18, University of Washington) will focus on accessing, analyzing, and interpreting underwater acoustics data using NSF OOI resources. Researchers working with or looking to integrate acoustics and complementary oceanographic data into their work are encouraged to apply. Submit your application before the deadline! ?? https://bit.ly/3CNxU7A #OOIFB #Acoustics #OceanData #MarineScience #NSFOOI

New research by Black et al. (2024) explores the effects of marine heatwaves (MHWs) on upwelling-driven phytoplankton blooms off the Oregon coast. Using OOI Endurance mooring data, satellite observations, and climate indices, they found that heatwaves compress phytoplankton blooms closer to shore, reducing their offshore extent. Key findings: ?? During MHW years (2015, 2019), blooms extended only 6–9 km offshore, compared to 34 km in normal years. ?? Reduced upwelling transport & nutrient flux limit bloom size. ?? Warmer waters physically displace blooms, affecting carbon transport in coastal ecosystems. ??

A Navy-funded project is using advanced tracking technology to monitor Pacific Salmon along the coasts of Oregon and Washington - and it’s leveraging OOI’s Endurance Array moorings to do it. Led by Dr. Taylor Chapple (Oregon State University), this research is part of the Marine Species Monitoring initiative, helping scientists understand fish movements in near-real time. Data from Vemco VR2C tag readers on OOI moorings not only supports marine conservation but also benefits commercial fishers, naval operations, and ecosystem research. But it’s not just salmon—these tag readers also detect sharks, sturgeon, and even Dungeness crabs! ???? ??

In addition to completing an AUV survey at the Pioneer MAB Array, the team inspected the Central Surface Mooring (CNSM) and downloaded Phytoplankton Imaging Data (PLIMS)—available soon after their return to Woods Hole Oceanographic Institution. They also recovered a glider that completed its deployment, collecting key oceanographic data: ? Fluorometer (FLORT) ? Dissolved Oxygen (DOSTA) ? Nitrate (NUTNR) ? Photosynthetically Active Radiation (PARAD) ? Current Velocity (ADCP) ? Conductivity/Temperature/Depth (CTD) Explore the data on OOI Data Explorer ?? https://lnkd.in/eDREzg2 ??: Collin Dobson #OceanResearch #PioneerMAB #MarineScience #AutonomousSystems #NSFfunded National Science Foundation (NSF)

Andy Robinson, Collin Dobson, and Natalia Moore from the Woods Hole Oceanographic Institution recently completed a cross-shelf and along-shelf survey of the Pioneer MAB Array aboard the R/V Virginia. The two REMUS600 autonomous vehicles collected key oceanographic data, including: ? Fluorometer (FLORT) ? Dissolved Oxygen (DOSTA) ? Nitrate (NUTNR) ? Photosynthetically Active Radiation (PARAD) ? Current Velocity (ADCP) ? Conductivity/Temperature/Depth (CTD) This work contributes valuable insights into coastal ocean dynamics available at: https://lnkd.in/eDREzg2 ??: Collin Dobson #OceanResearch #PioneerMAB #MarineScience #AutonomousSystems, #NSFfunded, National Science Foundation (NSF)

Jim Edson, OOI Principal Investigator, spoke at the POGO-26 Meeting in Penang, Malaysia, this week hosted by the Centre for Marine and Coastal Studies (CEMACS). He discussed the effects of El Ni?o and La Ni?a on coastal and marine environments and emphasized the vital role of sustained ocean monitoring in advancing climate research and resilience efforts. #POGO26 #OceanScience #ClimateAction #nsffunded Partnership for Observation of the Global Ocean (POGO)

Exploring Air-Sea Interactions at #AMS2025 ???? At the AMS Annual Meeting, OOI’s Principal Investigator shared key insights on air-sea interactions in extreme environments using OOI data. The findings sparked lively discussions, highlighting the growing impact of high-quality observational data in marine meteorology.

?? What Drives Deep Convection in the Irminger Sea? ????? New research using OOI data & CGSN team efforts finds atmospheric forcing is 3x more important than pre-existing stratification in shaping deep water formation. Despite climate-driven warming & freshening, heat loss still dominates winter mixing. ?? OOI Irminger Sea data + Argo, ECMWF ERA-5, & shipboard validation reveal year-to-year variability, impacting AMOC strength & ocean circulation. ??

We’re sharing the final student interview from last year's VISIONS’24 expedition aboard the R/V?Atlantis ?? ?? As part of the?Regional Cabled Array?operations and maintenance?2024 cruise, 24 undergraduates gained hands-on experience in oceanographic research—working with ROVs, collecting samples, and exploring deep-sea ecosystems along the Cascadia Margin. In this last reflection, PhD student Nichole Sams shares how she merged mental health research with deep-sea science and what she took away from the experience. ??

This #ValentinesDay, we’re celebrating an unexpected and heartwarming relationship - one that began on an OOI expedition and has since grown into an unbreakable bond. While on an OOI expedition in Punta Arenas, Chile, engineer Jennifer Batryn met Teddy, a street dog who quickly became her shadow - following her to the port, the warehouse, and even waiting outside restaurants. As their bond grew, Jennifer knew she couldn’t leave him behind. What followed was a journey of determination and logistics to bring Teddy home. Now a familiar face at Woods Hole Oceanographic Institution, Teddy is a daily reminder of the unexpected connections forged through science and exploration.
