CLIMODE: North Atlantic Mooring Temperature and Current Data

From November 2005 to November 2007, temperature and current data were collected from four subsurface moorings in the North Atlantic's subtropical gyre, southeast of the Gulf Stream. The dataset is part of the CLIvar MOde Water Dynamic Experiment (CLIMODE), focusing on a region of significant air-sea interaction and Eighteen Degree Water formation. Two heavily instrumented moorings were placed near the Gulf Stream, while two others with more limited instrumentation were located farther south.

Use Cases

• Analyzing temporal variability of ocean currents and temperature near the Gulf Stream based on the two-year mooring time series.
• Studying the formation and properties of Eighteen Degree Water using in-situ data from the outcrop region.
• Investigating the impact of cold air outbreaks on upper-ocean conditions using data from the heavily instrumented northern moorings.
• Validating and improving ocean circulation models with subsurface observational data from the subtropical gyre.

Strengths

• Provides a continuous two-year observational record from November 2005 to November 2007.
• Includes data from four distinct geographic locations, with two heavily instrumented sites offering more detailed measurements.
• Cross-platform presence on NASA Earthdata and Data.gov signals established curation and importance.

Limitations

• Metadata completeness is low: specific column names, row counts, and data formats are not detailed in the provided sources.
• Instrumentation suffered from 'blow down' and failures during the first deployment year, potentially creating data gaps.
• Conflicting 'last updated' timestamps (2007-11-12 vs. 2026-03-05) create uncertainty about metadata freshness.
