Autonomous Seagliders for Extended Missions under Arctic Sea Ice

Abstract

Rapid Arctic environmental change, exemplified by the recent, dramatic reduction in summertime sea ice extent, highlights the need to improve dynamical understanding of the dominant processes as a step toward developing both tactical and strategic forecast capability. The remote environment, ice cover and extreme operating conditions challenge conventional observing technologies and limit data availability beneath the ice and within the marginal ice zone, particularly during transition seasons (break-up and freeze-up). To provide observational capability in ice-covered environments targeted by upcoming ONR programs, four ice-capable Seagliders were fabricated and tested under this project.
