RV Atlantis (AGOR-25) is an oceanographic research vessel operated by the Woods Hole Oceanographic Institution and owned by the National Science Foundation. Designed for multidisciplinary oceanographic operations, she supports research in marine geology, physical oceanography, chemical oceanography, and biological oceanography. Atlantis serves as a platform for deployable vehicles, coring systems, and shipboard laboratories, facilitating collaborations among institutions such as Scripps Institution of Oceanography, Lamont–Doherty Earth Observatory, Monterey Bay Aquarium Research Institute, and international partners including the National Oceanography Centre and GEOMAR.

Design and Construction

Atlantis was designed as an oceanographic platform by naval architects and constructed by Halter Marine at their shipyard, reflecting design principles used in ships like RV Knorr and RRS James Cook. The hull and accommodations follow trends from the Robert D. Conrad-class lineage and incorporate diesel-electric propulsion systems similar to those on NOAAS Ronald H. Brown and R/V Thomas G. Thompson. Naval architecture tradeoffs were informed by operational requirements from the National Science Foundation and technical specifications used by Office of Naval Research, enabling dynamic positioning systems paralleling capabilities of RV Investigator and RV Tangaroa. Launch and christening events involved representatives from Woods Hole Oceanographic Institution, the United States Congress, and subcontractors with histories linked to Ingalls Shipbuilding and Bath Iron Works.

Since commissioning in 1996, Atlantis has conducted expeditions across the Atlantic, Pacific, Caribbean, and Southern Ocean, operating alongside platforms such as NOAAS Ronald H. Brown, RV Endeavor, RRS Discovery, and RV Pelagia. Her operational tempo has been coordinated with funding agencies including the National Science Foundation, program offices like the Office of Naval Research, and consortia such as the Scientific Committee on Antarctic Research. Atlantis supported international collaborations during programs connected to World Ocean Circulation Experiment, Census of Marine Life, and GEOTRACES. Maintenance periods and overhauls were carried out at shipyards with histories like Halter Marine and General Dynamics, and port calls have included Woods Hole, Massachusetts, San Diego, Nouméa, and Punta Arenas.

Atlantis is outfitted with modular wet and dry laboratories, CTD rosette systems used in studies by Scripps Institution of Oceanography and Lamont–Doherty Earth Observatory, and winches capable of deploying moorings and trawls similar to those used by Monterey Bay Aquarium Research Institute and National Oceanography Centre. She supports remotely operated vehicles in the style of Alvin and towed vehicle operations akin to Jason/Medea, enabling seafloor mapping with multibeam sonars inherited from technologies used on NOAAS Okeanos Explorer and RV Falkor. Atlantis's capabilities include coring tools comparable to International Ocean Discovery Program equipment and biogeochemical sampling suites employed in GEOTRACES campaigns. Data management follows community standards advanced by Integrated Ocean Observing System and archiving practices linked to Biodiversity Heritage Library-adjacent initiatives and repositories used by PANGEA (data repository) researchers.

The ship carries a complement of officers, crew, and scientific party members, drawing technical personnel with affiliations to institutions like Woods Hole Oceanographic Institution, Scripps Institution of Oceanography, Monterey Bay Aquarium Research Institute, and Lamont–Doherty Earth Observatory. Facilities include berthing and mess areas comparable to those on RV Knorr, acoustically isolated laboratories modeled after spaces aboard NOAAS Ronald H. Brown, and mission control rooms used to manage remotely operated vehicle operations similar to Alvin deployments. Safety, medical, and emergency-response protocols align with standards set by organizations such as the United States Coast Guard and certification bodies like American Bureau of Shipping. Training pipelines connect Atlantis personnel with programs at Massachusetts Institute of Technology, Woods Hole Oceanographic Institution's Oceanographic Center, and professional development venues used by Scripps Institution of Oceanography.

Atlantis has supported missions that contributed to discoveries in hydrothermal vent research alongside expeditions by Alvin and collaborations with investigators from Monterey Bay Aquarium Research Institute and Woods Hole Oceanographic Institution. She has participated in seafloor mapping efforts that informed plate tectonics studies related to the Mid-Atlantic Ridge and East Pacific Rise, working in concert with data from International Ocean Discovery Program cores and remote sensing from platforms like Jason/Medea. Atlantis supported multidisciplinary studies investigating ocean circulation relevant to World Ocean Circulation Experiment and biogeochemical campaigns tied to Census of Marine Life and GEOTRACES, yielding datasets used by researchers at Lamont–Doherty Earth Observatory and Scripps Institution of Oceanography. Mission collaborations have included scientists connected to the National Science Foundation, Office of Naval Research, and international programs coordinated through the Scientific Committee on Oceanic Research.
