Abstract:
These images and videos were acquired during expedition PS143 with the German ice breaker FS POLARSTERN in July 2024 supporting the time-series studies at the LTER (Long-Term Ecological Research) observatory HAUSGARTEN, situated in the Fram Strait between Greenland and Svalbard, in order to document natural and Global Change induced environmental variations on the polar deep-water ecosystems. The videos were acquired by AWIs OFOBS. Mission goal: Investigation of benthic habitats in the Fram Strait with a target altitude of 1.5 m. Mission was planned to follow the regular time-series transects at EGC-I. Mission comments: The laser markers are spaced 50 cm apart. The image coordinates were reconstructed based on the ships position.
