Temperature, salinity and acoustic backscatter observations and tidal model output in McMurdo Sound, Antarctica in 2016 and 2017
Temperature and salinity observations were made at nominal depths of 75 m and 100 m, respectively, by Sea Bird Electronics sensors. Acoustic volume backscatter measurements were made by an ASL Environmental Sciences Acoustic Zooplankton Fish Profiler (AZFP) operating at four-frequencies (125 kHz, 200 kHz, 455 kHz and 769 kHz). The AZFP profiled the top 25 m of the water column in 0.1 m bins. All instruments were deployed through a landfast sea ice cover that was approximately 2 m thick. The WWW Tide and Current Predictor model was used to generate tidal height forecasts for the deployment periods.
Ocean salinity was recorded at 10 second intervals by a Seabird Electronics SBE 37 microCAT CTD at a nominal depth of 100 m in McMurdo Sound at 77.6152 °S, 164.8821 °E. The dates covered by the salinity observations at 100 m depth are from 28-10-2016 06:43:11 UTC to 13-11-2016 21:59:51 UTC. The salinity is reported in units of practical salinity. Ocean temperature was recorded at 10 second intervals by a Seabird Electronics SBE 56 thermistor at a nominal depth of 75 m in McMurdo Sound at 77.6152 °S, 164.8821 °E. The dates covered by the temperature observations at 75 m depth are from 28-10-2016 06:43:11 UTC to 13-11-2016 21:59:51 UTC and 3-11-2017 08:26:01 UTC to 20-11-2017 23:00:01 UTC. The temperature is reported in units of °C in the ITS-90 temperature scale.
Tidal height forecast data were produced from the WWW Tide and Current Predictor (http://tbone.biol.sc.edu/tide/tideshow.cgi?site=Ross+Island%2C+Antarctica) for Ross Island, Antarctica, for the period of the 2016 AZFP deployments.
