Dataset Overview | National Centers for Environmental Information (NCEI)

Sound speed, water temperature, salinity and conductivity data from CTD taken from research vessels Sea Scout and C-Wolf in coastal waters of Texas, approaches to Galveston from 2017-09-14 to 2018-03-13 (NCEI Accession 0174501)

This dataset contains CTD measurements of sound speed, water temperature, salinity and conductivity in coastal waters of Texas, Gulf of Mexico, approaches to Galveston from 2017-09-14 to 2018-03-13. Casts were conducted at least twice a day on board R/V Sea Scout and at least once a day on board R/V C-Wolf. Dual CTD casts were obtained at least once a week to ensure a proper performance of sensors. Data from vessel Sea Scout and vessel CWolf contain salinity and conductivity, respectively. Data were collected under contract with the NOAA. Data are in cnv format.

Submission Package ID: B0YU6K
Purpose These data were collected in support of multibeam data collection. Variations in the speed of sound through the water column will affect the path of the acoustic pulse transmitted from the multibeam system and therefore will affect the depth and position of soundings. The multibeam data collected was corrected for the water column sound speed in real-time using the multibeam control software.

Processing Steps
  • Parameter or Variable: Sound Speed (CTD) (calculated); Units: m/s; Observation Category: in situ; Sampling Instrument: Seabird SBE 19plus CTD; Sampling and Analyzing Method: Data from CTD (conductivity, temperature and pressure) sensor lowered through the water column to the seafloor. Resulting data uploaded, examined and used to calculate sound speed through water column.; Data Quality Method: Dual CTD casts were obtained and reviewed together as a quality control check to ensure proper working order. The difference between the sound speed measured by the CTD and the sound speed calculated at the multibeam transducer was monitored in the multibeam control software. A difference of more than 2 m/s indicated a new cast may need to be taken..
