Marine Predators Monitoring
Parks monitored: Glacier Bay
Protocol under development - contents subject to change.
SEAN's long-term Marine Predators monitoring program is still under development. It is intended to fulfill these objectives:
- Determine long-term trends in the numbers and spatial distribution of marine birds and mammals within GLBA proper using grid-based sampling of at-sea surveys twice a summer stratified by along-shore (shoreline) and pelagic line transects that covers approximately 10% of the marine habitat.
- Generate population estimates for select marine seabird and mammal species or guilds from annual counts over the next 15-20 years.
