Hello from team acoustics! We’re now on leg three of the AMAPPS survey on the Henry B. Bigelow and for this leg we have had some ups and downs.
On the positive side, our hydrophone array has been really reliable lately! The ocean environment is a very stressful place for equipment, especially scientific equipment. Several times during the cruise we have had to fix problems at sea ranging from corroded connectors to bad hydrophone preamps (which required us to disassemble the entire array), but we have finally got everything in working order!
On the down side it has been pretty quiet during this leg, although there have been some really cool moments. Today we came across a mixed group of pilot whales and common dolphins which resulted in some great recordings, and
yesterday we had some killer whales swim right by the array! Overall, it has been a great cruise for the acoustics team. Personally I must admit that after being on all three legs of the cruise, I’m ready to set my feet on solid ground again!
