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 Ӱ, 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.
