Marine Mammals Monitoring for Northwest Fisheries: 2005 Field Year
A field program to monitor marine mammals during winter months in the coastal waters of Washington State has been established using Passive Aquatic Listeners (PALs). Upgrades to existing instruments and new operating software were utilized during the field year 2005. Two offshore moorings at Cape Fl...
