Expedition on R/V Sikuliaq to study changing climate in Arctic (Image 7)
Oregon State University oceanographers Dale Hubbard and Burke Hales are shown onboard the R/V Sikuliaq with the "SuperSucker," an instrument used to gather data on water chemistry and biology. The sensor-laden Supersucker is towed behind the ship as it pumps water into the lab onboard for rapid analysis. Data arrive as colored lines on a computer screen, indicating levels of oxygen, carbon and other elements dissolved in the sea. [Image 7 of 17 related images. See Image 8.]
More about this image
In September 2016, the National Science Foundation (NSF) funded an Arctic research cruise aboard the R/V Sikuliaq that included scientific teams from Oregon State University (OSU) and the Virginia Institute of Marine Science (VIMS).
The purpose of the expedition was to understand how a changing climate may be affecting the entire way of life in the Arctic. Oceanographers from OSU and VIMS took water samples from the Beaufort and Chukchi seas to observe how microscopic plants, called phytoplankton, are living and dying in the late summer, when there is less sea ice and more frequent storms. The scientists worked alongside the Sikuliaq crew to collect data, which they will continue to analyze and interpret in their labs back home.
The Sikuliaq is owned by NSF and operated by the University of Alaska Fairbanks.
