Cook Inlet Beluga Whale Aerial Survey - Post 7

June 10, 2016

Biennial survey of endangered Cook Inlet beluga whales.

Past abundance estimates and index counts collected during Cook Inlet beluga surveys.

Time to head back to Seattle to analyze video over the next few months. We will be comparing results from the video to our observer counts (index counts) and applying corrections for missed groups and counting biases (for example, when observers may over-count or under-count a group of belugas). Once all these corrections are made we will be able to estimate the abundance of the Cook Inlet beluga population for 2016. 

We will compare this abundance estimate to past estimates. This will provide us with a trend that will tell us whether the population is growing, declining, or stable for that period of time. We will look at the trend in estimates from the time hunting monitoring began (in 1999) and over the last ten years (2006-2016) to see if the population is beginning to show any signs of growth. Looking forward to returning home to our families and pulling together all the data we have collected!

Julie Mocklin is a NOAA Fisheries affiliate through the Joint Institute for the Study of the Atmosphere and Ocean at the University of Washington. Julie began her career as a whale watch naturalist and quickly moved on to conducting right whale and harbor porpoise aerial surveys in the Gulf of Maine.

Julie began working for the Marine Mammal Lab as a volunteer in 2002 and became part of the bowhead group in 2005. In the interim, she flew harbor porpoise surveys in Southeast Alaska and was the boat driver for a study on energetics and behavior of southern resident killer whales for the Northwest Fisheries Science Center, NOAA Fisheries.

Julie's career has focused on aerial surveys and obtaining photographs of cetaceans for abundance estimates and life history data. She got her Masters of Science at the University of Washington, using aerial photos to learn about bowhead whale feeding behavior.

Julie has worked as observer and videographer for the Cook Inlet beluga aerial surveys intermittently since 2007.
