Summary

Abstract:
Temperature depth devices (TDR) were attached to northern rockhopper penguins breeding on Nightingale Island (37 deg 25'S, 12 deg 28'W) to investigate temporal differences in diving behaviour throughout the species' breeding cycle.

The data sets comprise the unprocessed pressure and temperature data for each bird in .csv format.

Data were collected as part of the Darwin Plus funded Project Pinnamin (grant DPLUS 053), 2016 - 2018.

Lineage/Methodology: Temperature depth devices (TDR) were attached to northern rockhopper penguins during the brood-guard (females) and creche (females and males) breeding phases on Nightingale in 2016 to investigate temporal differences in diving behaviour between breeding cycles. TDR devices were deployed in combination with GPS tags and attached to animals' feathers on the dorsal mid-line of the bird's lower back using overlapping layers of black waterproof tape and cyanoacrylate glue. Birds were captured by hand or using a hand-held net at their nest site (during brood-guard) or in the colony when feeding chicks (during creche).

To reduce stress, only one bird per nest was tagged, with different birds captured during each breeding stage. Handling time was restricted to 15 minutes and birds were stained with temporary animal marker to allow them to be identified for recapture to retrieve loggers.

The TDRs were programmed to sample pressure and temperature every second.

Equipped birds were recaptured when seen returning from the sea or at return to the nest.

Instrumentation

Data Collection: The TDRs were programmed using the software G5 Host (Cefas Technology Limited, UK) to record hydrostatic pressure continuously at 1 s sampling interval. Pressure data were recorded with a resolution of < 0.4 m.
