Angmagssalik Array: Bottom Salinity and Temperature in the Denmark Strait, 1998-2015

Salinity and temperature data recorded near the seabed over 17 years from 1998 to 2015. Measurements were collected by Seabird-Electronics-37 SM MicroCAT instruments at the Angmagssalik Denmark Strait Overflow Array. The data were calibrated and aggregated from publications by Opher (2021) and Opher et al.

Use Cases

• Modeling deep-water overflow processes based on long-term near-bottom salinity and temperature records.
• Analyzing temporal trends in oceanographic conditions based on 17 years of calibrated instrument data.
• Validating climate and ocean circulation models based on data from a key overflow region.
• Studying the Denmark Strait's role in the Atlantic Meridional Overturning Circulation based on direct measurements.

Strengths

• Data spans a 17-year period from 1998 to 2015, providing a long-term observational record.
• Measurements are from calibrated instruments (Seabird-Electronics-37 SM MicroCAT) and are linked to specific publications.
• Data collection is focused on a critical oceanographic region, the Denmark Strait Overflow.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• Last update date is unknown; freshness unverified.
