Characteristics of seafloor ambient noise under different sea ice concentrations in the northern Chukchi Sea: Results from the N11 CHINARE ocean‐bottom seismic experiment
Abstract Seafloor ambient noise in the Arctic Ocean is related to sea ice. The characteristics of low‐frequency seafloor ambient noise (<10 Hz) in the northern Chukchi Sea have rarely been reported. Here, we investigated the seafloor ambient noise recorded using ocean‐bottom seismometers in the n...
