Arctic Benthic Community Time Series from Young Sound, Greenland (2003-2022)

14.3 MB of data on epibenthic community structure from Young Sound, NE Greenland, collected by Amalia Keck Al-Habahbeh. The dataset covers depths of 20m to 60m and spans two time periods: 2003–2010 and 2021-2022. It evaluates taxonomic and functional composition, noting brittle stars and bivalves comprised 95% of total abundances.

Use Cases

• Analyze temporal trends in benthic taxa abundance based on the fluctuating trends of brittle stars and bivalves mentioned in the description
• Model community dissimilarity based on environmental drivers like depth and ice-free period length described in the study
• Assess functional trait shifts in response to climate change based on the reported increase in size classes and feeding types
• Investigate the impact of longer open-water periods on higher trophic levels based on the described ecosystem changes

Strengths

• Data spans nearly two decades across two distinct sampling periods (2003–2010 and 2021-2022)
• Includes taxonomic and functional composition data for a community where two taxa comprise 95% of total abundances
• Collected via standardized methods using drop cameras and ROVs at specified depths (20m to 60m)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment for large-scale modeling
