3-Dimensional trajectories and positioning of individuals within an Antarctic krill swarm in the Southern Ocean - data from the TEMPO voyage of the RV Investigator

Progress Code: completed This metadata record describes the 3-Dimensional coordinates of individual krill obtained from the ‘Swarm study’ at-sea deployment of stereo-cameras. An array of 10 Gopro Hero-8 cameras (2 cameras on each lateral side of a cubic frame, and a pair on the bottom) was deployed...

Description
Summary:Progress Code: completed This metadata record describes the 3-Dimensional coordinates of individual krill obtained from the ‘Swarm study’ at-sea deployment of stereo-cameras. An array of 10 Gopro Hero-8 cameras (2 cameras on each lateral side of a cubic frame, and a pair on the bottom) was deployed into a krill swarm during the 2021 TEMPO (Trends in Euphausiids off Mawson, Predators, and Oceanography) voyage onboard the RV Investigator (see Kelly et al. 2021 for more details on the voyage). The primary goal of TEMPO was to collect data to estimate krill biomass with a view to update the precautionary catch limit for krill in CCAMLR’s Division 58.4.2-East. The aim of the Swarm study was to replicate the methods of Burns et al., 2023, in order to examine the individual level behaviour of krill in swarms in natural conditions. The TEMPO voyage ran from February to March 2021. The Swarm study system was deployed when a krill swarm was identified from the ships echosounder and weather and sea conditions allowed for filming (i.e. minimal to no wind or swell, full sun). This data product contains coordinates of individual krill in three dimensions from a pair of stereo cameras. There are 2 datasheets: TEMPO_Orientation TEMPO_Tracks TEMPO_Orientation: this dataset contains the head and tail coordinate of 305 individual krill obtained from videos deployed into a krill swarm date: date video obtained deployment: deployment no. of swarm study panel: panel cameras attached to (for video ID) left/rightcam: for ID camera_dist: horizontal distance between the two cameras left/rightvid: video filename framediff: difference in frames between left and right camera still: still photo reference number that orientation data was obtained from frame (leftvid): corresponding frame for still pointref: point of krill where coordinate (head or tail) id: individual krill x1/y1: xy coordinates from left camera x2/y2: xy coordinates from right camera convertedXYZ: converted coordinates into 3Dimensional TEMPO_Tracks date: date video ...
