Message from the Dean

Mark your calendars for the annual State of the College, which will be held in person in Fairbanks (O’Neill 201) and hosted virtually from 1–2 pm on Thursday, April 17. As in prior years, this event will highlight our progress in research, academics and service, and congratulate this year's recipients of the Dean’s Recognition Awards to our faculty, staff and students. I will also reflect on the successful implementation of the CFOS Decadal Plan over the past nine years; the plan was developed in 2016 following the restructure of our former School and Board of Regents approval of the College of Fisheries and Ocean Sciences.

It is a pleasure to recognize CFOS staff members who were honored for their longevity during last week’s Staff Recognition and Development Day. Thank you for your dedication and service to CFOS and UAF.

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!

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. 

R/V Sikuliaq

Sikuliaq is in Honolulu being prepared to mobilize the ROV Jason for Jim Potemra’s (University of Hawaii) ALOHA Cabled Observatory maintenance cruise. Station ALOHA comprises a 6-mile radius in the Pacific Ocean north of Hawaii where a variety of oceanographic research projects take place.

Accomplishments

 

Kay McMonigal was selected as a 2025 Kavli Fellow. Fellows gathered at the U.S. Kavli Frontiers of Science symposium March 6–8, bringing together a group of scientists 45 or younger who are “engaged in exceptional research in a variety of disciplines.”

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 UA Foundation. 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 Alaska Chapter of the American Fisheries Society 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

Message from the Dean

Uncertainty appears to be a certainty, at least for the near-term, in terms of federal agency support of our research and education enterprise. We are far from alone in having to adapt to these external forces. It may seem cliché to say that we will get through this, but we will. 

Over the past decade, together we have managed significant change at the unit level, navigated the most severe budget decrements in the history of the university, and adapted and grown our diverse research and education programs in the face of the global pandemic. Through all that turmoil our numbers speak for themselves: year-over-year increases in graduate and undergraduate enrollment, all-time-high revenues that position CFOS’s budget as the second-largest academic or research unit (financially) in the university system, and major facility operations that are second to none on a national basis. 

Naturally, we are all concerned about the future. But make no mistake, CFOS has proven to be remarkably resilient. I remain confident that we will not only get through this crossfire hurricane, we will emerge stronger and ever more important to the success of the university and the future of Alaska.

Hang in there, everyone—we will get through this together.

R/VSikuliaq

Sikuliaq is underway for the first of two Hawaii Ocean Time-series (HOT) 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.
