Ocean Floor Observation and Bathymetry System (OFOBS) seafloor images of the Fram Strait collected during RV POLARSTERN cruise PS136
During the RV POLARSTERN cruise PS136 (2023-05-22 to 2023-06-19) to the long-term ecological research station HAUSGARTEN observatory in the Fram Strait the Ocean Floor Observation and Bathymetry System (OFOBS) was used to collect still and video images from various locations surveyed during the expe...
