In this work package the focus will be on developing a RPAS based measurement system for measurements of sea-ice properties, detection and tracking of icebergs, detection and characterization of oil-spills. It is currently not possible to develop a aircraft system that could work under all weather conditions. Icing and high winds and turbulence limits flight window at low altitude. However we will look at new designs and technologies to maximize the operational window, while still keeping cost and size at a manageable level. New sensors are needed to accurate measure sea-ice thickness on a fine scale and detect oil in partly ice covered waters. Time of year, weather and ice type affects the penetration and accuracy of sensors used on sea-ice. A compromise must be made when it comes to weight, power consumption, and resolution. Multiple sensors may be needed to retrieve these properties and the combination of sensors might depend on time of year and weather.
Within WP4 CIRFA develops:
- Weatherization, like de-icing, cold climate robustness, wind tolerance.
- Radar and optical sensors for ocean state, sea-ice property and oil spill retrieval and detection
- Drop sondes for tracking of sea-ice and icebergs
WP4 will support WP1-WP3 data collection and algorithm validation in collaboration with the modelling and field activities in WP5 and WP6
