Spatial response of northeast Pacific groundfish to anomalous warming in 2015

This dataset consists of two types of observations collected during NOAA's Oscar Dyson cruise DY-15-06, 11 June to 16 August 2015 in the Gulf of Alaska. The data types are as follows: (1) vertical CTD profiles of water temperature and salinity. Some CTD casts were conducted with a Sea-Bird 911plus CTD on a rosette. These went from the surface to within a few meters of the sea bottom. Other CTD casts were conducted with a Teledyne RDI Citadel NV CTD attached to a midwater fisheries trawl net that fished in the depth range where walleye pollock (gadus chalcogrammus) were detected from the ship's fish finder, and (2) shipboard underway time series measurements of ship behavior (position, heading, course over ground, speed over ground), atmospheric (long- and short-wave solar irradiance, atmospheric pressure, temperature, humidity, wind speed and direction at 17 m) and oceanic (water depth, temperature, salinity, chlorophyll a and turbidity at 2.5 m) parameters. Underway variables are averaged over 1 minute from samples every 5 seconds. The data files are in the following formats: digital graphs in gif, underway times series in CSV and CTD profiles in NetCDF.
