The AOMIP science goals are to validate and improve Arctic Ocean models in a coordinated fashion and investigate variability of the Arctic Ocean and sea ice at seasonal to decadal time scales, and identify mechanisms responsible for the observed changes.

This part of the larger NASA ICESCAPE project examines the long-term, seasonal variability in phytoplankton abundance as a function of changes in sea ice cover, stratification, and temperature regimes measured in the Beaufort and Chukchi Seas throughout the growing season.

PI: Mike Steele; Co-I Ron Lindsay, Axel Schweiger, Jinlun Zhang The main objective of this study is to determine the fate of solar energy absorbed by the arctic seas during summer, with a specific focus on its impact on the sea ice pack. Investigators further seek to understand the fate of this heat during the winter and even beyond to the following summer.

This project supports the design, development, and implementation of a component of an Arctic Ocean Observing System in the Switchyard region of the Arctic Ocean (north of Greenland and Nares Strait) that serves the scientific studies developed for the IPY (International Polar Year), SEARCH (Study of Environmental ARctic Change), and related programs.

This slice of Dylan’s life, sponsored by the National Science Foundation and animated by student Anna Czoski, shows middle school students the role of phytoplankton in the Arctic.

This project aims to measure the time history of summer warming and subsequent fall cooling of the seasonally open water areas of the Arctic Ocean. Investigators will focus on those areas with the greatest ice retreat i.e., the northern Beaufort, Chukchi, East Siberian, and Laptev seas. Their method will be to build up to 10 relatively inexpensive ocean thermistor string buoys per year, to be deployed in the seasonally ice-free regions of the Arctic Ocean. Arctic-ADOS buoy data will be provided to both the research and operational weather forecasting communities in near real time on the International Arctic Buoy Program (IABP) web site.
