Message from the Dean
As noted below under Accomplishments, it is a great pleasure to congratulate Stephanie Madsen for being honored with the Vera Alexander Award for Marine Science and Education. Stephanie has been an ardent supporter of Alaska’s commercial fisheries in her former role as executive director of the At-Sea Processors Association, as well as through her service with the Pollock Conservation Cooperative Research Center, the CFOS Advisory Council, and the . I am very pleased that Stephanie has expressed her interest to remain actively engaged with CFOS research and education activities, and we very much welcome her continued insight and support. Congratulations Stephanie!
In just over two weeks, the 51st annual meeting of the will take place in Ketchikan. This meeting will provide a wonderful opportunity to showcase our fisheries research and education activities, and many presentations will be given by our faculty, students and collaborators. Andy Seitz recently began a four-year term on the Executive Committee of the Alaska Chapter, and is helping to organize this important meeting.
Daylight is increasing in our great state, and you can sense that spring is just around the corner—time to get that remaining seasonal skiing done.
R/V Sikuliaq
Sikuliaq is in port in Honolulu, Hawaii, preparing for the annual American Bureau of Shipping and U.S. Coast Guard inspections. These yearly inspections are required to maintain the Certificate of Inspection, issued once every five years, that shows vessels are seaworthy and safe for personnel.
Accomplishments
Stephanie Madsen was honored by the Pollock Conservation Cooperative Research Center with the Vera Alexander Award for Marine Science and Education. Madsen, a longtime PCCRC supporter and advisory board member, retired last year as executive director of the At-Sea Processors Association.
CFOS in the News
The Alaska Science Forum column, which is published in numerous outlets in the state, highlighted a 2023 cruise aboard R/V Sikuliaq that took cores from the ocean floor to learn about the Bering Land Bridge.

R/V Sikuliaq
) cruises this winter. For over three decades, scientists based at the University of Hawaii have conducted oceanographic studies of the “state of our sea” to establish baseline data at Station ALOHA. HOT cruises are usually conducted aboard R/V Kilo Moana; however, Sikuliaq is supporting this effort while the “KM” undergoes an extended drydock repair schedule.

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 Alaska, 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.
