Delaware II - Day Three

All the acoustic pop-up buoys in the array have been deployed and are now continuously recording underwater sounds. We spent the day documenting the distribution of marine mammals along our survey transects in Stellwagen Bank National Marine Sanctuary. Our target species are minke, fin, and sei whales but it was not until evening that we spotted two fin whales from the top deck and were able to follow them for a little while. We hope to correlate our visual sightings with the acoustic detections recorded on the buoys to gain a better understanding of the vocal repertoire of these species.
