Message from the Dean
Last week, the CFOS CFOS Advisory Council held a virtual meeting that included several new members. This was largely an introductory briefing to provide an overview of the growth and breadth of our college; specifically, our faculty, staff and student numbers (now over 450), revenues (doubled since CFOS was restructured in 2016), diverse research activities, academic programs, major facilities and ship operations, and development efforts. It is a pleasure to thank the Council for their valued input, and I look forward to working together to promote greater awareness, advocacy and support for the college.
The North Pacific Research Board will hold its fall board meeting this week in Anchorage, which will include discussions of core programs, the Northern Bering Sea Integrated Ecosystem Research Program, partnerships, and other board matters. Subsequently, the Alaska SeaLife Center will hold its annual fall retreat and board meeting in Seward to discuss strategic planning, governance, finance, development and community outreach. As in prior years, I look forward to engaging with the NPRB and ASLC boards and staff to help advance their respective missions.

Message from the Dean
Last week, UAF Interim Chancellor Mike Sfraga toured our Lena Point facility. My thanks to Mike for taking time from a busy schedule to learn more about our research activities and academic programs, and to Gabrielle Hazelton for coordinating this visit.
We are actively working on the 2025 Annual Report, to be published later this semester, which will feature some of our outstanding academic and research programs, major facilities, and amazing people that help make CFOS great. Speaking of which, our fall 2025 enrollment numbers indicate increases of 8% and 14% in undergraduate and graduate students, respectively. These impressive enrollment trends, combined with a striking 33% year-over-year increase in total FY25 revenues ($71.8M), underscore the growth, breadth and depth of our diverse academic and research programs. Bravo CFOS!
We will host a Coffee with the Dean this Thursday at 9 am in the O’Neill Dean’s Office suite—hope to see you there!

There is big news on the horizon for R/V Sikuliaq. The National Science Foundation has officially confirmed the ship will be headed south in the coming months to support three research projects off Antarctica, including work off Hawaii and Tahiti en route via Chilean waters to the Southern Ocean. The decision to use Sikuliaq reflects extremely well on our top-notch operations. Congratulations to our captain, crew, marine superintendent and the entire shoreside staff as they look forward to several months of work in the southern hemisphere. Bravo Zulu team Sikuliaq!

Message from the Dean
The Chancellor’s office recently charged UAF colleges and research institutes to consider the impact at the unit level of a hypothetical 20% decrease in federal grant funding and associated facilities and administration costs. As such, the Dean’s Office is preparing a response to this request with the goal of sustaining our academic and research programs and facility operations. Once we have transmitted our response to UAF leadership this week, these financial projections will be shared with the college while addressing any questions.
In the meantime, I feel confident that CFOS remains in a relatively good financial position and focused on growth of our academic and research programs. I fully appreciate your concerns in the face of possible significant reductions in federal agency research funding. Please be assured that I am committed to supporting our mission and the people that make our college proud.
On a somewhat related note, and bear in mind that I rarely call out specific PI grants, Jessica Glass’s (lead PI; co-PIs Brenda Konar, Ana Aguilar-Islas, Rich Collins) $1.9 million NSF proposal was funded through the (NSF EGFP). The project will provide support for 12 PhD students over three years. Congratulations to Jessica and team on this important award that will support our growing graduate academic program!

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!

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 UAF/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!
