The cruise KH 2018-709 aboard the Research Vessel Kronprins Haakon was the second process cruise of the project the Nansen Legacy. The cruise contributed to task T1-2, on process studies to investigate the atmospheric, oceanographic, radiative and other physical controls on sea ice and stratification, with a general aim to identify and quantify the processes that control the heat budget north of Svalbard and in the Barents Sea. The cruise aimed to deploy oceanographic moorings and gliders, an AUV, a remotely piloted unmanned aircraft, controlled meteorological balloons, collect underway measurements from ship-mounted ocean current profilers, wind profilers, radiometer and wave sensors, and collect ocean stratification, currents, and microstructure profiles along selected transects across the north Spitsbergen shelf and slope. Additionally, wave sensors were deployed at ice floes from ice edge into pack ice. This report provides an overview of the methods employed and the data collected.
The Winter Process Cruise (WPC) aboard RV Kronprins Haakon (KH2021702) conducted observations on processes that control the position and variability of the polar front in the Northern Barents Sea and the distribution of Arctic and Atlantic water masses. Moreover, the WPC serviced 2 gateway moorings sites (M1 and M4) and collected complementary hydrographic, microstructure and current profiles to detect the winter circulation pattern and the layering structures between the two competing water masses.
Meteorological measurements were also made.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
