Upper-Ocean Variability in the Arctic s Amundsen and Nansen Basins
Abstract
It is proposed to prepare and deploy an existing Ice-Tethered Profiler with Velocity (ITP-V) instrument in conjunction with the summer 2015 NABOS expedition (the Nansen and Amundsen Basins Observational System) to explore upper ocean variability and ice-ocean interaction in the Arctic s Amundsen and Nansen Basins as a complement to observations made in the Canada Basin during the Marginal Ice Zone DRI program of 2014. The fieldwork leverages previouslyplanned ITP deployments on this cruise in support of the NSF Arctic Observing Network program. Similar to the ITP-V deployments that contributed to the MIZ program, the proposed measurement program will return estimates of sea ice and ocean absolute velocity as well as the turbulent vertical transports of heat, salt and momentum just below the ice-ocean interface. Analysis of the recovered data will help extend the findings of the MIZ program to the European sector of the Arctic with its markedly different thermohaline stratification.
