Final research cruise to record sound in the Ross Sea
Scientist(s):
The PMEL Acoustics Program is back in the Ross Sea in Antarctica replacing six hydrophones that record icequakes, iceberg tremors and other naturals sounds near the Drygalski and Nansen Ice Shelves. The data collected from these hydrophones over the last four years will allow the Acoustics program to characterize the soundscape of the Terra Nova Bay polynya and to assess ice flow dynamics, as well as marine mammal presence/distribution in the newly formed Antarctic Marine Protected Area.
