Description
Gray whale calf production is estimated from data collected during the northbound migration as whales return to their feeding grounds in the Arctic. Counts of adult female whales with calves are made by observers and used to make the estimates.
Gray whale abundance is estimated from data collected during the southbound migration from feeding grounds in the Arctic to breeding grounds in the lagoons of Mexico. Observers record counts of whales as they pass the long-term study site at Granite Canyon, California.
Gray whale abundance is estimated from data collected during the southbound migration from feeding grounds in the Arctic to breeding grounds in the lagoons of Mexico. Counts of whales made from thermal imagery recorded during the migration are used to estimate abundance.
