Sea Ice Fatty Acids and Stable Isotopes from 2018 Arctic Spring Campaign

Fisheries and Oceans Canada collected baseline ecological data on sea ice communities in the Tuvaijuittuq region during the 2018 spring field campaign. The dataset provides fatty acid composition and stable isotope signatures from multi-year and first-year ice ecosystems. It serves as foundational knowledge for this unique Arctic environment.

Use Cases

• Analyze fatty acid composition across multi-year and first-year ice types to assess ecosystem differences.
• Model stable isotope signatures to trace nutrient sources and trophic relationships within sea ice communities.
• Establish baseline fatty acid and stable isotope metrics for monitoring climate change impacts in the Tuvaijuittuq region.

Strengths

• Data originates from the first ecosystem study of the poorly characterized Tuvaijuittuq region.
• Provides coordinated physical, biochemical, and ecological measurements from a 2018 spring campaign.
• Focuses on the unique multiyear ice ecosystem in the Arctic Ocean's Lincoln Sea.

Limitations

• Sample size and number of data rows are unknown, limiting statistical power assessments.
• Data is from a single spring campaign in 2018, lacking temporal replication or seasonal comparisons.
• Geographic scope is limited to the specific Tuvaijuittuq region offshore CFS Alert.
