The Pacific Arctic region, including the northern Bering and Chukchi seas, is undergoing unprecedented and accelerated ecological change, including reduced sea-ice extent and thickness and prolonged periods of open water. In order to address the fundamental knowledge gaps related to these physical changes and their biogeochemical response, direct observations of ecosystem-sensitive tracers at both high spatial and temporal resolution are sorely needed to better understand mechanisms driving variability in this important region. In order to test several hypotheses related to the controls and spatial-temporal patterns in elemental cycling and productivity of the Pacific Arctic, we carried out a number of measurements aboard the R/V Norseman II (Support Vessel of Alaska) using the vessel's surface underway system. Specifically, we installed a number of instruments connected to the R/V Norseman II surface underway science seawater system that included a four-position manifold that allowed surface underway water ...
