Abstract:
During the PS124 Expedition to the Weddell Sea, Feb - Mar 2021, an extensive brooding colony of Neopagetopsis Ionah was discovered on the eastern flank of the Filchner Trough. Extensive towed camera deployments gauged some of the extent of the colony. To complement this spatial data a mooring was deployed at the site (PS124: SWS-WetCam), equipped with two cameras and lights for imaging the seafloor. Standard Raspberry Pi cameras developed within AWI were used for this (Purser et al. 2020), together with Deep Sea Power and Light illumination. In this dataset, images collected with one of these cameras (one failed on deployment) from 28th February 2021 until 29th April 2022 are presented. Images were taken with a six hour tempral spacing from an altitude of ca. 3m above the seafloor.
