This dataset contains water temperature, salinity, currents, and other parameters taken during four field campaigns that occurred in LeConte Bay (near LeConte Glacier) in southeast Alaska in August 2016, May 2017, July 2017, September 2017, and September 2018. During the cruises data were collected with (i) remote control kayaks that were operated from the Motor Vessel (MV) Steller or the MV Amber Anne and (ii) the MV Pelican (landing craft). The kayak surveys were done within a few hundred meters of the terminus of LeConte Glacier in order to characterize the upwelling plume at the glacier-ocean boundary, while the MV Pelican operated about 1 kilometer (km) down fjord and conducted repeat transects across the fjord. We collected water column temperature, salinity, and depth data using a conductivity, temperature, and pressure device (CTD) and water velocity data using acoustic doppler current profiles (ADCPs). The kayak was equipped with a 300 kiloHertz (kHz) system. The MV Pelican had two pole-mounted acoustic doppler current profiler (ADCP) systems, a 600 kiloHertz (kHz) to capture upper layer velocities in more detail and a 150 kHz ADCP to reach the bottom and characterize the entire water column flow.
