Ocean Observatories

NSF's OOI is a science-driven ocean observing network that delivers real-time data from more than 900 instruments to advance ocean science.

What drives coastal flooding during storms?

Using data from the OOI Pioneer Array, researchers found the New England shelfbreak jet accounted for nearly 30% of sea level variability during storm surges.

Tiny deep-sea foraminifera are colonizing plastic debris thousands of meters below the surface. New research using OOI platforms shows plastics may become long-term habitats that influence deep-sea biodiversity and ocean chemistry.

The Central Surface Mooring is now deployed in the Mid-Atlantic Bight! 🌊 Onboard, the Imaging FloCytoBot is capturing microscopic ocean life—revealing plankton dynamics, ecosystem health, and changing ocean conditions.

Pioneer23 has been hard at work since departing @whoi_ocean on April 25.

Northern Surface Mooring (NOSM) has now remained at sea for over a year—far beyond its typical deployment—while continuing to deliver critical ocean and weather data.

New funding for Deb Kelley (UW) and Jonathan Sharp (CICOES/NOAA PMEL) will integrate 10+ years of OOI Regional Cabled Array data into machine learning models to improve Pacific Northwest coastal forecasting.

🌊 Infrastructure Feature: AUVs

AUVs are self-propelled vehicles that move sensors through the ocean in 3D.

⚙️ Propellers + thrusters; ~1.7 m/s (up to ~2.5 m/s)
📡 Multi-sensor, long-range; GPS at surface
🌎 OOI Endurance & Pioneer Arrays

What if subsea cables could listen to the Earth?

UW + Nokia Bell Labs used DAS on the NSF OOI RCA to turn fiber cables into sensors for quakes, waves, and marine life.

👀 It’s Friday the 13th…

Deep-sea hydrothermal vents are some of the ocean’s most mysterious places - where superheated fluids rise from the seafloor and life thrives in darkness.

🔬 Science Highlight: Carbon in the ocean’s twilight zone

Using EXPORTS and OOI data from Station Papa, researchers studied carbon cycling at 100–500 m depth and found supply didn’t balance demand.

At #OSM2026, Jim Edson, Lead PI of OOI, presented an overview of more than a decade of biogeochemical & physical ocean data collected through OOI observatory.

A clear takeaway from this morning’s session: sustained observations remain foundational to ocean science.
