Change in the Weather
It is fascinating how quickly weather can shift at sea. The Revelle crew keeps tabs on these changes and posts them online. Here is a graph of the changes that occurred from 6:51 AM February 23 to 6:51 AM February 24. As the red line shows, the air temperature descended about 10 degrees Celsius from late afternoon to evening February 23. This coincided with crossing a weather boundary called the sub-Antarctic front. From now on, we should expect colder temperatures and colder waters.
