Abstract: Conditions just under Arctic sea ice during Winter and Spring months are largely a mystery, but we do know they play a critical role in shaping one of the world’s most highly productive ecosystems during the ice-free Summer months. Large ice keels, constantly shifting floes,and broad inaccessibility make data collection under sea ice notoriously difficult. To answer this question, a new under-ice mooring, capable of collecting oceanographic data at the water-ice boundary during these vital periods was designed. The newest generation of instruments will collect daily images; measure temperature, depth, PAR, and fluorescence;and transmit all data to shore using Iridium Short Burst Data. We will discuss how a number of novel design elements have been integrated to create low-cost, high quality instruments and the challenges that have emerged throughout the process. This project is funded by Pacific Marine Environmental Lab’s Innovative Technology for Arctic Exploration program with in-kind support from Ecosystems and Fisheries Oceanography Coordinated Investigations.
