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

A time-series analysis of epibenthic community structure in Young Sound, NE Greenland, from 2003–2010 and 2021-2022. Data collected by drop cameras and ROVs at depths of 20m to 60m evaluates taxonomic and functional composition. The dataset was authored by Amalia Keck Al-Habahbeh and shared under a CC-BY-4.0 license.

Use Cases

• Analyzing temporal trends in benthic taxa abundance based on the reported fluctuating trends for brittle stars and bivalves.
• Modeling community dissimilarity based on environmental drivers like depth and ice-free period length mentioned in the description.
• Investigating shifts in functional traits (e.g., size classes, feeding types) in response to longer open-water periods.
• Assessing the vulnerability of Arctic coastal ecosystems to climate change based on the reported structural and functional shifts.

Strengths

• Time-series data spans nearly two decades, covering 2003–2010 and 2021-2022.
• Data collection methods (drop cameras and ROVs) are specified, providing context for the imagery-derived counts.
• Key findings are summarized, including that brittle stars and bivalves comprised 95% of total abundances.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a DOCX (3.0 MB), which may require extraction or conversion for analysis.
