Abstract:

This dataset contains the CTD, ADCP, meteorological, and flow-through instrumental data collected during an expedition of the R/V Weatherbird II cruise WB0517 to the northwestern margin of Cuba from 2017-05-09 to 2017-05-25. The dataset includes conductivity, temperature, salinity, fluorescence, turbidity, photosynthetically available radiation (PAR), sound velocity, density, air pressure, wind speed, wind direction, location, and depth parameters. The CTD data were collected at 22 CTD stations. The R/V Weatherbird II cruise WB0517 was led by chief scientist Dr. Steven A. Murawski.

Purpose:

To provide baseline measurements of water samples, fish populations and sediments in advance of potential future oil contamination along the northwestern Cuban continental shelf and slope.

Data Parameters and Units:

CTD Data: date[yyyy-mm-dd], time[HH:MM:SS], latitude[deg], longitude[deg], depth[m], temperature[deg C], conductivity[S/m], salinity[PSU], oxygen[umol/Kg], oxygen saturation[umol/Kg], density[kg/m^3], fluorescence[mg/m^3], turbidity[NTU], PAR[umol photons m-2 s-1], altimeter[m], sound velocity[m/s], average sound velocity[m/s]. ADCP data (from VmDas User Guide): .ENR - Raw ADCP data file. .LTA – Long time period averaged ADCP data. .STA - Short time period averaged ADCP data. .ENS - ADCP data after having been screened for RSSI and correlation by VmDas, or adjusted by the user via a User Exit. Also has Navigation Data records merged into the ensembles from the.NMS file. .ENX - ADCP single-ping after having been bin-mapped, transformed to Earth coordinates, and screened for error velocity, vertical velocity, and false targets. This data is ready for averaging. .N1R, .N2R, .N3R - Raw NMEA data files - text files; includes ADCP timestamps with the following format: $PADCP,eeeee,yyyymmdd,hhmmss,-nnnnn.nn Where: eeeee = ADCP ensemble number yyyymmdd = Year, Month, Day (date of ADCP ping) hhmmss.ss = Hour, minute, seconds.hundredths (Time of ADCP ping) -nnnnn.nn = (signed) PC clock offset from UTC in seconds; includes time zone difference). The .N1R extension is used for single-port NMEA data collection, or for GPS position data (Nav) in dual-port collection mode. The .N2R extension is used for Roll/Pitch/Heading (RPH) data collection when using two serial ports for NMEA data collection. .NMS - Binary format NAV data file after having been screened and pre-averaged. .VMO - The option settings used for collecting the data (text file). Data Acquisition System (DAS) Data - Data in this section are organized by ship instrument used to collect navigational and environmental information.
