Once again we had to pull in the seasoar this afternoon and strap it to the deck because of the weather. It is a little harder getting the seasoar back on deck in high seas. Nevertheless, we were able to get a couple good runs in. The hydrographic structure observed so far has been highly viable. We did two sections along the western edge of the study area to give some indication of the temporal variability. In the first section, there is a 4 degrees C temperature contrast over 12 km near the surface. Just 12 hours later, the temperature contrast has increased to 6 degrees C over 20 km. Also, the salinity at the offshore edge has increased with the intrusion of a warm core ring. The shelfbreak front has changed considerably within 12 hours and since the shipboard ADCP has been consistently observing 10-80cm/s westward flow, the changes can happen as quickly as 8 hours!
