In January, I had the pleasure of speaking at the Channel Islands Maritime Museum in Oxnard, kicking off their 2026 Invited Speaker Series. In my talk, “Beneath Pacific Tides: Tales from over 75 Years of Ocean Observations in California,” I took the audience on a journey through some of my favorite stories from CalCOFI’s decades of ocean research.

Hi, my name is Mallory! I’m a current Master’s student at SIO, and I got to help out with CCE and CalCOFI data collection on the cruise! As an undergraduate student, I had worked on consolidating and organizing PRPOOS plankton data from the CCE LTER database, so it was a satisfying, full-circle moment to finally get to be out on the ship, seeing the origin of where that data came from.

My name is Marialena Christopoulou, and I am a Customer Support Scientist in Physical Oceanography at Sea-Bird Scientific. From November 9th to 18th, I had the opportunity to join a CalCOFI cruise aboard the R/V Sally Ride.

I still can remember the first time I had the opportunity to sail on a large research vessel. We transited nearly 300 miles off the California coast. As we moved into the open ocean, the water became a deep crystal blue. The color and quality of the water was unlike anything I had ever seen in my life and the clarity of the water felt almost symbolic. Being that far offshore, aboard a large ship, and immersed in the vastness of the ocean, made the importance of ships very clear to me. I realized what an essential platform they are to connect people directly to the open ocean and to each other, to enable essential data collection, and to underpin science that serves society.

Technicians from ESNZ joined the CalCOFI 2511 cruise to gain hands-on experience with at-sea instrumentation, calibration, and sampling workflows. From CTD operations and SUNA integration to oxygen sampling techniques, the exchange provided valuable insight that will help inform future Deep Argo float deployments and strengthen international collaboration in ocean observing.

My name is Ella Crotty, a recent college graduate and lab volunteer at Scripps Institution of Oceanography, and the Fall 2025 CalCOFI cruise was my first multi-day research cruise! I was aboard as a volunteer on the MOSAIC (MURI Ocean Sampling Across an Integrated Continuum) project, a project that uses environmental DNA (eDNA) to detect marine mammals along the route of the CalCOFI cruise.

Please join us for this year’s CalCOFI Conference 2026, A Decade of Remarkable Change: Heatwaves, HABs, Hypoxia, and Other Ocean Changes off the California coast, which will be held May 27th and 28th, 2026 at the Scripps Institution of Oceanography Seaside Forum, La Jolla, CA. The conference will happen in-person and will consist of keynotes, panels, contributed talks, posters, and discussions.

In November, I was invited to speak about my CalCOFI research on the Trophic Efficiency in Early Life Hypothesis at the 2025 PICES meeting in Yokohama, Japan. This talk was part of a session on “Applying Innovative and Established Approaches to Assess the Resilience of the Early Life Stages of North Pacific Fishes to Changing Oceanographic Conditions”.

In November 2025, I flew across the largest and deepest ocean on Earth and landed in Japan for a week of discovery and collaboration (and amazing food!) at the North Pacific Marine Sciences Organization (PICES) annual meeting. PICES promotes and coordinates marine research in the North Pacific. The conference brought together over 600 ocean professionals from across the North Pacific to explore Innovative Approaches and Applications to Foster Resilience in North Pacific Ecosystems.
