August 30th 2025 17:03 local (Pacific): Offload of all OOI equipment and personnel is now complete, and we have officially reached the end of the VISIONS’25 expedition. Thanks to the Atlantis crew, Jason team, the SSSGs, and all UW and APL personnel the cruise was a complete success, accomplishing all of our goals and then some, including several PI projects. We look forward to sailing with them again soon!

August 28th 2025 17:49 local (Pacific): Jason is continuing the photomosaic of Southern Hydrate Ridge — the dive will likely last until  ~2330 tonight, marking the end of the RCA efforts for this year.

August 28th 2025 13:03 local (Pacific): The Atlantis is on station at Southern Hydrate Ridge and will dive shortly (J2-1744). The vehicle will be flying 4-5 meters off the seafloor in straight lines, so that the continuous photos will have overlap in the N-S and E-W  directions. When done this will provide a nearly one-of-a kind image of a methane seep — few have been completed elsewhere in the oceans and almost even less as time-series mosaics of these rapidly changing seascapes/biological habitats.

August 28th 2025 09:36 local (Pacific): The Atlantis is in transit to Southern Hydrate Ridge. Once onsite, Jason will dive (J2-1744) for the photomosaic survey.

August 28th 2025 09:12 local (Pacific): Jason is on deck. This marks the completion of all the RCA scheduled work for 2025 – 47 Jason dives. We will  have one more dive (~11 hrs) to photomosaic Southern Hydrate Ridge, documenting its profound changes since last year.

August 28th 2025 08:25 local (Pacific): The camera turn was successful at the Shelf site. Jason is conducting an imaging fly around for documentation. Once on deck the Atlantis will transit to Southern Hydrate Ridge for an 11 hr photomosaic dive (J2-1744).

August 28th 2025 00:44 local (Pacific): The BEP swap dive (J2-1741) completed slightly ahead of schedule, and the Atlantis began the steam back to OR Shelf at 2206. We should arrive on site in a few minutes, at which point we will prepare to swap out the digital camera (J2-1742), a 3-4 hour Jason dive.

August 27th 2025 19:09 local (Pacific): Dive J2-1740 successfully replaced the digital camera at the Oregon Offshore site, and J2-1741 just launched to turn the Benthic Experiment Package (BEP) at the same location. This dive should take about five hours and be back aboard by midnight.

August 27th 2025 15:55 local (Pacific): Dive (J2-1740) is on-going at the Oregon Offshore (580 m) — lots and lots of sable fish visiting us as we turn the digital still camera.

August 27th 2025 10:05 local (Pacific): The sonar platform was successfully deployed at OR Shelf, but conditions were still marginal for the heavier BEP and undervator dives. So we are moving back to the 600 m OR Offshore site to turn the BEP and camera there (order of dives TBD).

August 27th 2025 09:44 local (Pacific): Jason dive J2-1739 is ongoing at the 80 m site installing the zooplankton platform. The yellow float on a filament (blue tape) gets released when the sonar is on and floats into the view of the sonar for calibration. Following this, the digital still camera will be turned.

August 27th 2025 08:28 local (Pacific): Conditions have improved enough to attempt our first dive at the 80 m Oregon Shelf site. Dive J2-1739 will go in the water shortly to deploy the bioacoustic sonar platform.

August 27th 2025 02:16 local (Pacific): The R/V Atlantis is currently at Oregon Shelf on a weather hold for the night. Diving conditions will be re-evaluated around 0500.

August 26th 2025 14:30 local (Pacific): A shallow CTD verification was done for the Shallow Profiler mooring. Seas there not conducive for diving with a BEP. The Atlantis is steaming back to the Shelf (80 m water depth site) to assess conditions. Still looking better tomorrow.

August 26th 2025 09:34 local (Pacific): The swells are still a little too large and unpredictable for a loaded Jason dive, so we’re heading over to OR Offshore to do a shallow CTD cast (CTD-010).

August 26th 2025 04:13 local (Pacific): The R/V Atlantis has just arrived on station at Oregon Shelf. Weather conditions are being assessed to see whether diving conditions are favorable. 

August 26th 2025 01:08 local (Pacific): The Atlantis has begun the 3-hour transit to the Oregon Shelf (80 m) site. Once we arrive, we will assess the sea state and determine whether we can begin dive operations or hold for more favorable weather.
