Dataset Overview | National Centers for Environmental Information (NCEI)

Water speed, acoustic echo intensity from moored ADCP and water temperature, conductivity, and other parameters taken by CTD from research vessels Strickland and Heron in coastal waters of southeast Alaska and British Columbia from 2015-06-14 to 2015-06-16 (NCEI Accession 0202076)

This dataset contains water conductivity and temperature casts collected by CTD from the research vessel Heron. Voltage profiles were measured by an optical backscatter probe deployed from research vessel Heron.

ADCP instrument was deployed 30 m above the seabed, suspended from a fixed vessel (research vessel Strickland). The research vessel Strickland was moored (using 4 anchors) above the central submarine channel downstream of the Squamish delta.

File Beamave_EA.txt contains the echo intensity averaged between four ADCP beams in counts. Echo intensity was used to derive the concentration of suspended sediment from 30 m to 60 m water depth, using an acoustic inversion method and physical samples for calibration.

File vmag.txt contains the magnitude of velocity in m/s. These data were used to obtain the turbidity current measured on 15th June 2015.

Data are in ASCII format.
