ISHTAR is a multi-disciplinary, multi-university ecosystem study designed to test the hypothesis that interannual changes of atmospheric forcing on water transport through the Bering Strait result in a two-fold to four-fold difference in: (1) the flux of nutrients from the shelf break of the northwestern Bering Sea; (2) the primary production north of St. Lawrence Island; (3) the burial of carbon in Chukchi Sea sediments; (4) the amount of energy passed up the food web; and finally (5) the chemical properties of the Arctic Ocean water transported south across the Greenland-Scotland ridge system. The northern Bering Sea extending from St. Lawrence Island to Bering Strait was chosen as the site for studying phytoplankton populations and their role in transporting organic carbon. The authors major scientific responsibilities in the ISHTAR program are to: (1) provide phytoplankton boundary conditions for models constructed by other components; (2) obtain time series suitable for identifying interannual variations in phytoplankton standing stocks; and (3) identify the dominant time and length scales of the phytoplankton distributions. In addition, they construct, maintain, calibrate, and deploy the moored fluorometers used to make the required measurements.
