Between September to December 2016, Global Positioning System (GPS Pathrack) data loggers were attached to breeding northern rockhopper penguins during the three distinct stages of the nest-attendance part of their breeding cycle; incubation, brood-guard and creche, on Nightingale (37 deg 25''S, 12 deg 28''W; 4 km2) and Inaccessible (37 deg 17''S, 12 deg 40''W; 14 km2) Islands. This tracking data successfully augments and complements existing data sets for the species breeding in the South Atlantic, which enables systematic identification of areas of particular relevance for this species, and thus to help determining whether there is a need to improve marine spatial planning in form of e.g. Marine Protected Areas in the island''s Exclusive Economic Zone (EEZ). Data were collected as part of the Darwin Plus funded Project Pinnamin (grant DPLUS 053), 2016 - 2018.

Geolocators (Global Location Sensing - 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 augments and complements existing datasets for the species breeding on Nightingale Island and enhances 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 (grant DPLUS 053), 2016 - 2018.
