The accompanying jdfSummary.mat file comprises the data described in the manuscript "Wave Breaking Dissipation in a Fetch-Limited Sea" by Michael Schwendeman, Jim Thomson, and Johannes Gemmrich. This data was taken from the Strait of Juan de Fuca, WA on February 14-15. Wind and wave data have been separated into data structures for February 14 and 15 (four structs). Also included are the Λ(c) breaking distributions and coincident wind/wave values (one struct). Structures and variables are described below: ________________________________________________________________________________________________________________________________________________________________________________________________________ jdfWindFeb14, jdfWindFeb15 - wind data taken from the sonic anemometer mounted above the wheelhouse of R/V Robertson. fetch - Uniform 500m grid measured from the ship GPS lat/long along the mean daily wind direction from coastline estimated by piecewise linear functions (Fig. 1, Schwendeman et al.). Remaining variables have all been averaged over these 500m fetch bins. time - Time in UTC in Matlab serial date format. lat - Latitude from ship GPS. lon - Longitude from ship GPS. u10 - 10-meter mean wind speed (in m/s). uStar - Wind u* calculated from the inertial dissipation method (see Yelland et al. 1994), in m/s. windDir - Daily average wind direction relative relative to true north (in degrees). ________________________________________________________________________________________________________________________________________________________________________________________________________ jdfSwiftFeb14, jdfSwiftFeb15 - wave and dissipation data averaged from two SWIFT drifters. fetch - Uniform 500m grid measured from the SWIFT GPS lat/long along the mean daily wind direction from coastline estimated by piecewise linear functions (Fig. 1, Schwendeman et al.). Remaining variables have all been averaged over these 500m fetch bins. time - Time in UTC in Matlab serial date format. lat - Latitude from SWIFT GPS. lon - Longitude from SWIFT GPS. z - Depth bins of ADCP, measured down from instantaneous water surface (in meters). volDiss - Volumetric turbulent dissipation calculated from ADCP measurements using structure function method (see Thomson, 2012). In m^2/s^3. totalDiss - Depth-integrated turbulent dissipation (in W/m^2 after multiplying by water density) with 0.5 W/m^2 background dissipation subtracted off. f - Frequency bins for spectrum (in Hz) fSpectrum - Frequency spectrum measured from SWIFT GPS (see Herbers et al. 2012). In m^2/Hz. tp - Peak period from the maximum of the frequency spectrum (in seconds). te - Dominant period from the normalized first moment of the frequency spectrum (in seconds). mss - Wave mean square slope, calculated from frequency spectrum. hSig - Significant wave height, in meters. backgroundDiss - 0.5 W/m^2, subtracted from integral of volDiss in calculating totalDiss (see Schwendeman et al.). ________________________________________________________________________________________________________________________________________________________________________________________________________ jdfLambda - Λ(c) whitecap distribution from shipboard video records (7 from Feb. 14 + 2 from Feb. 15 = 9 total records). time - Beginning time of video record in UTC in Matlab serial date format. c - Speed bins for Λ(c) (in m/s). lambda - Λ(c) distribution calculated via the Fourier method (see Schwendeman et al.), in s/m^2. fetch - Ship fetch (in meters). All following wind/wave parameters are spatial averages around the surrounding 500m. cp - Wave peak phase speed (in m/s). mss - Wave mean square slope. hSig - Significant wave height (in m). u10 - 10-meter mean wind speed (in m/s). uStar - Wind u* (in m/s).
