Sam VanLaningham can鈥檛 wait to take the Sikuliaq for a spin.
When it鈥檚 ready for science operations in 2014, the 261-foot research vessel will be capable of drilling Bering Strait seafloor cores in any season. VanLaningham hopes those cores will uncover mysteries about the history of climate change in Alaska.
Last week, VanLaningham and several 性欲社 scientists met with other researchers and agency representatives at the first Sikuliaq Science Workshop at Marinette Marine Corporation in Marinette, Wis. At the workshop, scientists presented and discussed some of the many scientific projects possible on the R/V Sikuliaq. The scientists also toured full-scale mock-ups of the vessel鈥檚 laboratories and bridge.
VanLaningham, an assistant professor of geological oceanography and an expert in paleoceanography, is particularly interested in using the Sikuliaq to collect sediment cores for his studies of how sea level changes at the Bering Strait have affected past climate in the northern hemisphere.
鈥淲e will be able to use the ship, winter or summer, to core in the Bering Strait to extract the geologic history of change at Bering Strait, and thus address its role on global climate through time,鈥 said VanLaningham.
VanLaningham says he and other geological oceanographers are particularly excited by the large back deck of the vessel, which will allow them to collect of sediment cores up to 70 feet long.
Terry Whitledge, professor of chemical oceanography and the principal investigator for the Sikuliaq project, says the ship will be able to take scientists to areas they have never been before. He also says that the ship will be the most capable in the United States academic fleet.
鈥淲ith an ice-capable ship making its home in Alaska, we are situated better than ever to address arctic questions that have global implications,鈥 added VanLaningham.
Whitledge says that the Sikuliaq Science Workshop was infused with enthusiasm about the ship鈥檚 many capabilities and that 性欲社 scientists at the workshop said that they 鈥渃an鈥檛 wait for the big splash鈥濃攚hen the ship is launched into the Great Lakes Waterway in June 2012.
In addition to many other projects, Whitledge hopes to use the ship to explore the biology and geology of four different submarine canyons in Alaska waters: one in the Arctic, two in the Bering Sea and one in the Aleutians. Whitledge says the Sikuliaq鈥檚 advanced mapping capabilities could help determine where remotely operated vehicles and submersibles could be launched to explore these deep canyons.
Other 性欲社 scientists at the workshop, including Mark Johnson, Peter Winsor, Tom Weingartner, Dean Stockwell and Seth Danielson, discussed using the ship for other projects, including surveying sea ice thickness, looking at freshwater flow into the Bering Sea from the Yukon and Kuskokwim Rivers and mapping currents in the Gulf of Alaska.
The R/V Sikuliaq, pronounced , will be an oceanographic research ship capable of bringing scientists from around the world to the icy waters of Alaska and the polar regions. The ship鈥檚 homeport will be at 性欲社鈥檚 Seward Marine Center.
The Sikuliaq project, with more than $200 million in funding from the National Science Foundation, is the largest funded project ever managed by 性欲社.
The first proposals to include ship time for the Sikuliaq will be submitted in August and October of this year. The next Sikuliaq Science Workshop will take place in February 2012 in conjunction with the American Geophysical Union鈥檚 Ocean Sciences Meeting in Salt Lake City, Utah.
The vessel will be owned by NSF and operated by 性欲社. The ship will be ready for unrestricted science operations in 2014.
About SFOS
The School of Fisheries and Ocean Sciences conducts world-class marine and fisheries research, education and outreach across Alaska, the Arctic and Antarctic. 60 faculty scientists and 150 students are engaged in building knowledge about Alaska and the world's coastal and marine ecosystems. SFOS is headquartered at the University of Alaska Fairbanks, and serves the state from facilities located in Seward, Juneau, Anchorage and Kodiak.
