Environmental security in Arctic ice-covered seas: from strategy to tactics of hazard identification and emergency response

Key aspects of environmental security in ice-covered waters are examined, with special focus on tactical and operational information needs. High-resolution data of ice hazard distributions, ice movement and deformation are required for monitoring of environmental hazards and effective emergency response in sea ice environments. A prototype coastal observing system has been developed at Barrow, Alaska that addresses these types of information needs. Assessments of potentially hazardous ice conditions by local experts are combined with imagery obtained from a marine X-band radar with a digital controller and data from on-ice sensors (ice thickness, ice and water temperature, sea level). Digital imagery and data are processed and disseminated in near-real time. Using Hidden Markov Modeling, early onset of hazardous events is detected, which provides decision support in operational settings. The utility of the system and strategies towards integration with broader emergency response efforts is evaluated.
