High-resolution 3D reconstructions were generated from the imagery to quantify sponge biomass and tissue volume, including both healthy and decaying individuals, to assess changes across seasons. These data provide information on sponge population dynamics, growth rates, distribution, and predator interactions, contributing to understanding the role of glass sponges as foundational, habitat-structuring species within Antarctic benthic ecosystems\n\nGET DATA: ian.hawes@waikato.ac.nz", "keywords":[ "K884A","POPULATION ESTIMATES","POPULATION DYNAMICS","SPONGES","POPULATION DISTRIBUTION","POPULATION SIZE","ROVS","FIELD SURVEYS","UNDERWATER VIDEO CAMERA","MCMURDO SOUND","ANTARCTICA","ASP" ] ,"creator": [ { "@type":"Person" ,"name": "Hawes, I." ,"email": ["ian.hawes@waikato.ac.nz"] ,"contactPoint": { "@type" : "PostalAddress" } } ] ,"publisher": [ { "@type":"Organization" ,"name": "University of Waikato" ,"email": [""] ,"contactPoint": { "@type" : "PostalAddress" } } ] ,"distribution": [ { "@type":"DataDownload", "contentUrl": "https:\/\/antcat.antarcticanz.govt.nz\/geonetwork\/srv\/api\/records\/183932a5-b222-4e49-bd26-aba0035a9978", "encodingFormat": "WWW:LINK-1.0-http--link", "name": "Distribution Metadata" }] ,"encodingFormat": [ ] ,"spatialCoverage": [ {"@type":"Place", "description": [ ], "geo": [ {"@type":"GeoShape", "box": "-77.8679 166.5924 -77.8348 166.7828" } ] }] ,"temporalCoverage": [ "2024-10-26/2025-11-23" ] ,"license": [ { "@type": "CreativeWork", "name": "This data set conforms to the CC BY Attribution License (https:\/\/creativecommons.org\/licenses\/by\/4.0\/)" } ] , "citation": "Hawes, I., ( 2024 ) Glass Sponge (Hexactinellid) Imagery and Photogrammetry Data from ROV Surveys, McMurdo Sound, Antarctica, 2024-2025.
