Kelp habitat density and composition from underwater video

Annotations of canopy forming seaweed derived from towed video at selected key abalone blocks along the east coast of Tasmania. The purpose of the study was to examine the patch dynamics of seaweeds and urchin barrens and to provide validation for the identification of urchin barrens from multibeam surveys.

Statement
Towed underwater video was collected at selected key abalone blocks along the east coast of Tasmania (Blocks 22/23 –Tasman, Block 24 - Maria, Block 27 - Freycinet, Blocks - 29/30 St Helens). These blocks were chosen as prior diver and towed-video surveys revealed highly variable urchin densities and overgrazing impacts ranging from small metre-scale incipient barrens up to larger barrens features up to ~100s m in length. The video footage was annotated at the scale of individual kelp patches, whereby the start and end-point of individual patches were recorded as precisely as possible with the assistance of Biigle video analysis software (https://biigle.de/). The different kelp patches were categorised based on the canopy species and the overall percentage cover of the canopy (sparse = 0-20% cover, middle= 20-60%, dense=60-100% cover). Eck= Ecklonia radiata, Phyll = Phyllospora comoasa, Cys= Cystophora sp. Other = all other canopy species, bare= completely bare reef. These annotations were then matched to GPS coordinates collected from a transponder mounted to the camera platform.
