Description
Greenland's continental shelf is surveyed by NASA's Oceans Melting Greenland mission using airborne and ship-deployed probes. The data contains in situ profiles of salinity, density, temperature, and sound velocity from AXCTD, CTD, and AXBT instruments, collected annually from 2016 through 2021. The goal is to quantify the ocean's contribution to the melting of Greenland's glaciers.
Use Cases
Modeling ocean heat transport to glaciers based on temperature and salinity profiles
Analyzing seasonal and interannual variability of water column properties around Greenland
Calibrating and validating satellite-derived oceanographic data with in-situ measurements
Studying the relationship between ocean characteristics and glacial melt rates
Strengths
Data collected via specialized airborne probes (AXCTD/AXBT) in regions inaccessible to ships
Covers the entire continental shelf surrounding Greenland in annual surveys
Includes multiple complementary instrument types (AXCTD, CTD, AXBT, gravity data)
Explicit temporal coverage from 2016 through 2021
Limitations
Column-level documentation is absent; field semantics must be inferred after download
Row count and dataset size are unknown, which may limit suitability assessment
