This is a scanned copy of the vertebrate biology report from Macquarie Island by David Slip. The report was split into two documents, and has been scanned as such. The topics covered in the report include: - Elephant seal census - Elephant seal tagging program - Resights of tagged seals - Electrophoretic studies - Blood chemistry - Time depth recorders and satellite telemetry deployment - Pup and weaner weights - Calculation of body fat - Anesthetics - Examination of diet through stomach lavaging - Leopard seals - Survey of marine debris

This is a scanned copy of a register of Elephant Seal tagging data from Macquarie Island from October 1987 to March 1991.

At Heard Island, Southern Indian Ocean, seals were branded between 1949-1953. Seal length was measured in feet and inches. Recaptures of seals were made up until 1955, and growth and age-specific survival was calculated.
