Pioneer 22 wrapped up successfully, with the team back to Woods Hole Oceanographic Institution (WHOI). After recoveries, deployments, and sampling across the shelf break, the ship even had a dolphin escort on the way home. Kudos to the CGSN team for their hard work.

The team deployed and recovered the Northern Profiler Mooring (NOPM) during Pioneer 22 - key work that keeps high-resolution water-column data flowing from the OOI Pioneer Array. See more on the blog: https://t.co/aZR2Qjkhqf #OOIDataMatters

Why turn the OOI Pioneer Array every six months? To stay ahead of biofouling, which can degrade sensor performance over time. Regular swaps keep data quality high and operations running smoothly. 🔗 More: https://t.co/aZR2Qjkhqf #Pioneer22 #OOIDataMatters

Autonomous vehicles extend OOI’s reach beyond fixed platforms. At the Pioneer Array, gliders operate nearly year-round, while AUVs collect high-res seasonal data during cruises—together offering a detailed view of the Mid-Atlantic Bight. Expedition Blog: https://t.co/aZR2Qjkhqf

The Shallow Water Mooring at the Pioneer Array samples the upper ocean (20–30 m depth) using a Prawler profiler powered by the motion of the buoy. It measures salinity, temperature, oxygen, & more, sending data to shore in near-real time. 🌊 Read more: https://t.co/aZR2Qjkhqf

The team has loaded the R/V Neil Armstrong for Leg #1 of the Fall 2025 Pioneer 22 cruise, carrying all 3 mooring types—Coastal Profiler, Shallow Water, & Coastal Surface—for flexible operations in any conditions. 🌊 Learn more on our blog: https://t.co/aZR2Qjkhqf

Lahr et al. (2025) use OOI EA data to reveal how sediment moves in Astoria Canyon, WA 🌅 Summer: internal tides & nonlinear waves drive resuspension 🌊 Winter: >10 m storms move all grain sizes 🌀 Detached canyon heads still export sediment Read more 👉 https://t.co/7mwthbmM7J

A new study by Krauss et al. (2025) reports the first tremor-like seismic signals offshore Cascadia, detected by OOI’s seafloor instruments. These signals may reveal how megathrust earthquakes begin. 🔗 Read the Science Highlight: https://t.co/BFsmBWvOsv

OOI shared Slocum glider results from the Pioneer Arrays and 8+ yrs of basin-scale ops at the 2025 Slocum Glider User’s Conf. The week ended with the Sentinel Mission launch - the first attempt to autonomously circumnavigate the globe by Slocum AUV. 🔗: https://t.co/R329VuOmRX

Today is Day 2 of the Axial On-line Workshop. Researchers share new results on the Axial Seamount: seismic imaging, magma movement, hydrothermal systems & eruption timing. 🔗: https://t.co/CSOPLZhrcs #OOI #AxialSeamount #OceanScience #Volcano 📸: UW/NSF-OOI/WHOI,V25
