Barents Sea Spring Production and Climate Forcing Data, 1998-2023

The Barents Sea ice zone (38°E–52°E, 69°N–78°N) is the focus of this dataset supporting a study on declining marine primary production. It contains source data for figures and tables, including time series for primary production (1998–2023), chlorophyll-a (2000–2022), sea-ice concentration, and model outputs from MITgcm and HadCM3. Author Chao Zhang published the data on figshare in 2026 under a CC-BY-4.0 license.

Use Cases

• Analyzing trends in spring marine primary production based on Ocean Colour satellite data from 1998-2023.
• Modeling the impact of reduced sea-ice concentration on the Barents Sea energy budget using data from HadCM3 perturbation experiments.
• Estimating horizontal velocity and nutrient transport budgets across the Barents Sea Opening using MITgcm and NEMO-PISCES model outputs.
• Assessing the statistical significance of environmental trends using the provided linear regression results and t-test p-values.

Strengths

• Covers a long temporal range for key variables: primary production from 1998 to 2023 and chlorophyll-a from 2000 to 2022.
• Integrates multiple data sources, including satellite observations (Ocean Colour, MODIS), in-situ calibrated data, and climate model outputs (MITgcm, HadCM3, NEMO-PISCES).
• Includes statistical significance assessments (p < 0.01) for trends, as indicated by hatched bars in the source data.

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 the specific Barents Sea ice zone study area.
