LeConte Bay Oceanographic Data from CTD and ADCP, 2016-2018

Four field campaigns in LeConte Bay, Alaska, collected water column data from August 2016 to September 2018. Measurements include temperature, salinity, depth, and water velocity profiles using a CTD and two acoustic Doppler current profilers (ADCP) mounted on research vessels. The dataset, supported by the National Science Foundation Polar Programs, focuses on ice-ocean interactions near the LeConte Glacier.

Use Cases

• Modeling glacier melt rates based on temperature and salinity profiles near the ice front.
• Analyzing seasonal current variability in a glacial fjord based on ADCP velocity data.
• Studying water column stratification and mixing processes based on CTD-derived temperature and salinity.
• Investigating the impact of glacial freshwater input on near-surface ocean layers based on upper-layer ADCP data.

Strengths

• Data spans multiple seasons across four campaigns from 2016 to 2018, allowing for temporal analysis.
• Velocity profiles characterize the entire water column using dual-frequency (150 kHz and 600 kHz) ADCP systems.
• Associated bathymetry and CHIRP subsurface datasets are documented and linked for complementary analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
