EOP active acoustics
These data contain shipboard active acoustics data collected in the Pacific, both pelagic and near shore environments. Data is collected using Simrad EK60 splitbeam multifrequency systems with the transducers pointing vertically down in the water column. The echosounders operate up to four frequencies at 38 kHz, 70 kHz, 120 kHz, and 200 kHz.
