The third COMPASS glider mission by Seaglider (Ardberg) was depolyed by Scottish Association for Marine Science in Spring 2021. The glider deployed in the Hebrides, off the West coast of Scotland, will contribute to the oceanographic and acoustic observational programme for the INTERREG Va funded COMPASS Project. As with two previous glider missions, which took place in 2018 and 2019, this mission will provide high-resolution datasets of water properties from the Malin shelf, spanning coastal Irish waters, coastal Scottish waters and Atlantic influenced waters near the shelf edge.
These missions which last 6 to 8 weeks collect date including temperature, salinity, oxygen, dissolved oxygen, chlorophyll, fluorescence and optical backscatter. The gliders are fitted with passive acoustic sensors to detect and monitor marine mammals which will enhance the work undertaken by the COMPASS Cetacean Team.
