CHAOZ passive acoustic mooring CZ11_AU_C02 data



These data represent results from the 2011-12 Chukchi Acoustics, Oceanography, and Zooplankton (CHAOZ) passive acoustic deployment of the offshore Icy Cape mooring, CZ11_AU_C02. Data are presented as a percentage of time intervals per day with calls for each species. For example, a result of 0.15 means that 15% of all possible time intervals of recordings for that day contained calls of that particular species. Values of 111 mean there was too much noise or acoustic masking to determine if calls were present. Times are reported in Alaska Daylight Time (AKDT, UTC -8).
