Virtually nothing is known about leatherback turtle diving strategies, but on Nov. 12, 2010, an international team of UK and US based scientists publish their discovery that leatherbacks regulate their buoyancy by varying the amount of air they inhale before they dive. Fitting nesting leatherbacks with triaxial accelerometers, temperature and pressure gauges, the team were able to make the first detailed recordings of leatherback turtle diving behavior.
