Delaware II - Day Five


Photo by C. Khan collected under NOAA/NMFS/NEFSC permit.

Today was another fabulous day out on Stellwagen Bank! We expected fog, rain, and rough seas, but it turned out to be pretty nice most of the day and we were able to get a lot of work done.

We retrieved the seven pop-up buoys that had been deployed to calibrate the array. An acoustic signal is played to the buoy which triggers a cable to burn, thereby freeing the buoy to "pop up" to the surface where it can be grappled and retrieved.

We collected a lot of data on humpback and fin whale positions before the winds finally kicked up enough to be a problem. There was a lot of breaching activity today, and towards the end of the day, I finally had my camera at the right moment...
