Derived from colour images collected during NUI dive 015. Model S2. 3D .pdf seafloor model of area of Karasik seamount with 100% sponge and spicule coverage, showing 3D weaving structures remaining on the seafloor following sponge movement. Derived from OFOBS collected HD video frames presented in V2_sized (82-90 seconds into the video).V2_sized. .mp4 video snippet of Langseth ridge summit flank.
