Information from animal-borne data loggers was used to characterize the dive‐surfacing behavior of cryptic loggerhead turtles (Caretta caretta) in the northwest Atlantic from 2009-2018. Our data covered a large geographic area off the east coast of North America, and allowed us to present estimates for and variation in 3 metrics that can be used to assess availability bias affecting visual surveys: average dive duration, average surface duration, and the proportion of time at the surface.
