Marine benthic biodiversity survey comprising seabed video and imagery from Rothera Point, November 2023 to February 2024
This dataset comprises video and imagery captured around Rothera Point, Adelaide Island on the West Antarctic Peninsula between November 2023 and February 2024. The data was captured as part of a biodiversity survey on an area to the North of Rothera Research Station. Operations were conducted off small boats and allowed data to be collected in shallow waters between 10 m and 60 m water depth. The dataset includes: seabed imagery captured using a down-facing drop camera, video footage from a Boxfish Luna remotely operated underwater vehicle (ROV), timelapse imagery from a camera installed on the Rothera Research station watch tower and video and imagery of a sediment profiler experiment of the seabed.
Data were collected by personnel at BAS, funded by the Antarctic Infrastructure Modernisation Project (AIMP) Runway Project.

Still imagery was quality assured in-situ via a live-view screen, this allowed repeated images to be taken assuring enough data from each site. Images were identified twice to allow an overlap for quality control. The CTD was calibrated by Valeport. All taxa in the sediment samples were identified under microscope. Images of and a subsample of taxa were sent to experts for further identification.
The ROV video stills were only accepted under strict criteria. The ROV needed to be at less than 1 m altitude above the seabed, at an angle of 45 degrees or greater. The frame needed to be in focus with adequate lighting for species identification.
The SeaPen required the GoPro''s to be reviewed on a computer screen. As such repeat data collection trips were made to certain sites to make sure enough data was collected per site.
