    "description": "This metadata record describes baseline data on the population density and size structure of glass sponges (Hexactinellid) collected from up to three coastal sites around Ross Island, McMurdo Sound, during the 2024 field season. Surveys were conducted using remotely operated vehicles (ROVs) to map sponge populations to depths of approximately 100 m. These observations provide quantitative information on population dynamics, growth rates, and spatial distribution, forming the foundation for future monitoring and long-term ecological assessment. The research contributes to understanding the role of glass sponges as foundational, habitat-structuring species within Antarctic benthic ecosystems.\n\nGET DATA: ian.hawes@waikato.ac.nz",
