Rare, deep-sea encounter: California scientists observe'extraordinary' seven-arm octopus On November 6, 2025, MBARI Senior Scientist Steven Haddock and researchers in MBARI's Biodiversity and Biooptics Team observed a seven-arm octopus (Haliphron atlanticus) during an expedition in Monterey Bay with MBARI's remotely operated vehicle at a depth of approximately 700 meters.

Locked down in London at the height of the pandemic, bombarded with scary news, I'd felt my connection with nature starting to fray. The daily hour we were allowed to walk in the park for exercise became for me (and many others) a lifeline. And for these walks, I took my phone--not to chat, but to learn. Despite being a well-traveled wildlife filmmaker, I was shamefully clueless about the names and habits of many of the species native to my homeland. Soon a tree-identifying app introduced me to the flora I'd been strolling past.

Expeditionary Artificial Intelligence is the theme for the May 2020 research and experimentation week during which Private Industry, Academia, and Non-Government Organizations will collaborate on developing and demonstrating Machine and Deep Learning, sensor, networked all-domain Autonomous Systems, and other technologies. The May 2020 experiment will be co-hosted by The Sea Land Air Military Research initiative (SLAMR) and Joint Interagency Field Experimentation (JIFX) Program. The initial TechOp Day at the Naval Postgraduate School (NPS) was part of the laying the groundwork with Private Industry and other partners. This video was produced by NPS and can be watched at NPS' YouTube channel at https://www.youtube.com/user/NPSvideo.

NASA has announced that a team of researchers from its Jet Propulsion Lab (JPL) and other institutions recently visited Monterey Bay, California as part of ongoing research into developing artificial intelligence for submersible drones. In addition to benefitting our understanding of Earth's marine environments, the team hopes this artificial intelligence will someday be used to explore the oceans believed to exist on moons like Europa. If confirmed, these oceans are thought to be some of the most likely places to host life in the outer solar system. A fleet of six coordinated drones was used to study Monterey Bay. To plot their routes, forecasts of these ocean features were sent to the drones from shore. The drones also sensed how the ocean actively changed around them.

If you think operating a robot in space is hard, try doing it in the ocean. Saltwater can corrode your robot and block its radio signals. Kelp forests can tangle it up, and you might not get it back. Sharks will even try to take bites out of its wings. The ocean is basically a big obstacle course of robot death.
