Sea Water Temperature and Salinity

The protocol used by the lighthouse keepers here at Race Rocks for at least the last 20 years is as follows:

  • 1 hour before the Victoria high tide a 4L black bucket on a 6m tether is tossed off the end of the jetty, pulled back and then dropped straight down and retrieved.
  • The mouth of the bucket reaches a depth of ~1m, the bottom ~1.3m
  • Temperature is taken directly from this bucket for "sea temperature" in the data logs
  • In the past a more precise measurement of "jar temperature" was taken with a different thermometer in a graduated cylinder filled with water from the bucket within 2 minutes of sampling in an unheated building.
  • As of March 28, 2010, a digital thermometer is used for both measurements.January 2009
