SASSIE ECCO: Arctic Ocean Density and Pressure Daily Data, 2014-2021

Daily-averaged model-simulated ocean density and hydrostatic pressure from January 15, 2014, to February 7, 2021. The data is from the SASSIE ECCO Version 1 Release 1 ocean and sea-ice state estimate, produced by the POCLOUD organization. It covers the Arctic polar region at 90 depth levels from 0.5 to 6760 meters on a high-resolution curvilinear grid.

Use Cases

• Analyzing salinity-driven stratification in the upper Arctic Ocean based on the simulated density fields.
• Studying the impact of sea ice melt on ocean hydrostatic pressure based on the provided pressure data.
• Validating regional ocean circulation models using the high-resolution, downscaled ECCO state estimate for the Arctic.
• Investigating long-term changes in Arctic ocean density profiles based on the 7-year daily time series.

Strengths

• Covers a 7-year period from 2014 to 2021 with daily temporal resolution.
• Provides data at 90 vertical depth levels, from near-surface (0.5m) to deep ocean (6760m).
• Uses a high-resolution downscaled grid (1/12 degree) for the Arctic domain, derived from a global 4D ocean circulation model.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2021-02-08 00:00:00; freshness should be verified.
