Geolocators (GLS) were attached to northern rockhopper penguins breeding on Nightingale Island (37 deg 25 S, 12 deg 28 W: 4 km2) with the aim to study the species'' dispersal in the inter-breeding period, 2017. This data successfully augmented and complemented existing datasets for the species breeding on Nightingale Island and enhanced our understanding of the species'' distribution at sea throughout their annual cycle.

There are four different data types for each penguin a) the unprocessed light sensor data, b) the unprocessed activity (wet/dry) data, c) the unprocessed temperature data and d) the estimated positions using the BAStag and SGAT packages in R.

Data were collected as part of the Darwin Plus funded Project Pinnamin, 2016 - 2018.
