Sermilik Fjord Hydrographic Data from Moored Buoys (2012-2013)

September 2012 to August 2013 data from four instrumented moorings deployed in East Greenland's Sermilik Fjord. The dataset captures water temperature, conductivity, and current measurements at depths ranging from 125 to 880 meters. It was collected by the National Oceanic and Atmospheric Administration (NOAA) and is hosted on multiple government data platforms.

Use Cases

• Analyzing seasonal temperature and salinity stratification using CTD (Conductivity, Temperature, Depth) sensor data.
• Modeling fjord circulation patterns from current meter (ADCP, Aquadopp) velocity measurements.
• Investigating glacial meltwater intrusion and its effect on near-surface water properties.
• Calibrating regional ocean models with in-situ hydrographic time-series data.
• Assessing instrument performance and data recovery rates across different mooring configurations and depths.

Strengths

• Data collection spans a full annual cycle from September 2012 to August 2013.
• Instruments were deployed at multiple strategic locations and depths (125m, 290m, 880m) within the fjord system.
• Cross-platform presence on Data.gov and NASA EarthData indicates recognized scientific value and curation.

Limitations

• Specific column names, row counts, and file sizes are not provided by any source, limiting immediate usability assessment.
• A conflict exists in the 'last updated' metadata, with Data.gov showing 2026-03 05 and NASA EarthData showing 2013 08 20.
• One of the five deployed moorings was not recovered, resulting in incomplete spatial coverage.
