Abstract
In March of 2022, a sensor package was installed on board the CCGS Henry Larsen. The package contained a camera network which recorded ice around the vessel (360°), forward-looking Light Detection and Ranging device (LIDAR) and stereo cameras. This visual and topographical sensor package was supplemented with a data acquisition system which recorded propulsion, GPS, speed and heading information. This paper discusses and presents analysis work using the raw field data towards generating a continuous record of ice conditions. We present results towards automating the extraction of concentration from forward looking cameras, and estimation of the ridge sail height distribution near the vessel from LIDAR. The performance of the sensors and concepts for future ship based sensing projects are presented and discussed.
