Southern Ocean Seafloor Habitats and Communities, Responses to Climate and Fishing Drivers

Brasier et al. (2021) compiled knowledge on Antarctic seafloor habitats and communities, focusing on their responses to global and local drivers of change. The dataset likely contains information from ship-based surveys and monitoring sites, addressing spatial variability in the Southern Ocean benthos. It was published in Frontiers in Marine Science and is hosted by Geoscience Australia.

Use Cases

• Assessing vulnerability of calcifying species based on susceptibility to ocean acidification mentioned in the description
• Modeling habitat suitability for commercial fish species based on identified seafloor diversity hotspots
• Identifying priority conservation areas based on described vulnerable regions like the West Antarctic Peninsula
• Evaluating the impact of fishing gear on slow-growing habitat-forming species like sponges and corals

Strengths

• Focuses on high-spatial-variability Antarctic shelf habitats identified as diversity hotspots
• Cites specific vulnerable regions and species groups, including the West Antarctic Peninsula and calcifying organisms
• Based on a peer-reviewed publication in Frontiers in Marine Science (doi: 10.3389/fmars.2021.622721)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to data_gov_au and the specific research focus
