2:15 Identification of additional research/management actions, if any, needed to protect humpback whales in Glacier Bay, e.g.: a. Research 1. Physical i. acoustic characteristics of the Bay ii. water currents and tidal factors 2. Biological i. identification of whale food and its distribution and abundance ii. additional whale behavior studies including harassment indicators 3. Human Factors i. acoustic characteristics of vessels b. Management 1. comprehensive monitoring of vessel use patterns throughout the Bay 2. vessel routing, number, and speed controls 3. seasonal and/or area closures
