Message from the Dean
As we close out the first half of 2025, it is worth reflecting on a few important accomplishments to date. We continue to see strong enrollment in our undergraduate and graduate degree programs. We hired new faculty and staff, including Krista Oke as assistant professor of fisheries, Luke Canady as financial manager, and Makiko Shmagin as procurement technician. Our world-class research programs and major facilities are second to none, and we continue to operate Sikuliaq under a new cooperative agreement with the National Science Foundation. Taken together, we can be proud of our collective expertise and capabilities in delivering excellence in research, instruction and outreach. Thank you CFOS for all your good work.
We have made a great visual improvement to make our website more dynamic and attractive for recruiting, so take a look at the new home page. This will be updated with new video clips in the future, so please consider submitting a video for consideration to post.
CFOS can now claim a presence from the deep sea to the highest mountain in North America. Kudos to CFOS research staff Hank Statscewich for his successful summit of Denali last week, and . Congrats, Hank!
Wishing everyone a safe and enjoyable Fourth of July weekend.

It is a pleasure to convey that Dr. Krista Oke has accepted the offer for the tenure-track assistant professor position in the Department of Fisheries. Krista completed her PhD at McGill University, conducted multiple postdocs, and is currently a research assistant professor at ÃÛÌÒÓ°Ïñ Pacific University. Her research focuses on understanding organisms’ responses to environmental change, and she aims to advance ecosystem-based fisheries management of ÃÛÌÒÓ°Ïñ fisheries. Our thanks to Peter Westley for chairing this faculty search and to committee members Courtney Carothers, Kristen Gorman, Andrés López, Lindsey McCulloch and Megan McPhee. Krista will be based at our Lena Point facility with a start date of May 2026. Please join me in welcoming Krista to CFOS.

Message from the Dean
It is a great pleasure to convey that the National Science Foundation has renewed our cooperative agreement to continue operation of R/V Sikuliaq through the end of calendar year 2028. A particular point of pride is that after a rigorous review process, NSF renewed the cooperative agreement directly with ÃÛÌÒÓ°Ïñ/CFOS, rather than competing the ship nationally with other potential operators. I wholeheartedly congratulate the captains, crew members, marine superintendents, our shoreside staff, and all of our federal agency partners for their dedication and excellent work in support of Sikuliaq ship operations over the past decade—BZ team!
Speaking of the ship, Gabe Matthias has accepted the position of science operations manager for R/V Sikuliaq. Gabe earned a Blue MBA degree from the University of Rhode Island and has considerable experience working at sea. He has worked as a marine technician for more than nine years, including time aboard R/V Savannah, Endeavor, two years in the UNOLS Tech Pool, and the past year aboard Sikuliaq. Please join me in congratulating Gabe on his new appointment.

Message from the Dean
It is my pleasure to convey that Dr. Thilo Klenz has been appointed Research Assistant Professor in the Department of Oceanography. A CFOS alum (Ph.D., 2023), Thilo is known to many in the college as a seagoing physical oceanographer who has participated in research cruises in the tropical Atlantic and Pacific, the subpolar North Atlantic, the Arctic Ocean, the Gulf of ÃÛÌÒÓ°Ïñ, and off Antarctica. His research focuses on the physics of ocean circulation and turbulent mixing, using a combination of ocean drifters and related observation platforms and modeling approaches. Please join me in congratulating Thilo!
This week the and partners will host the 2025 in Anchorage. As in past years, CFOS researchers and students will have a major presence at this meeting. CFOS will host a booth, so please stop by during the poster sessions if you plan to attend. As part of AMSS, the annual Coastal Marine Institute symposium will be held Friday morning, and presentations by researchers supported by the Pollock Conservation Cooperative Research Center will run concurrently.
R/V Sikuliaq
Sikuliaq is moored at the University of Hawaii Marine Center pier in Honolulu, Hawaii. After unloading science gear from the Jurassic Quiet Zone seismic survey, Sikuliaq will be prepared for four research cruises and three short repair periods over the next few months.
