This study was carried out by Giulia Roncon as part of her PhD at IMAS. The study employed both archival and contemporary diving data, collected by six species of marine predators (three penguins and three seal species) from the Eastern Antarctic sector of the Southern Ocean, to clarify key questions, such as (i) are there differences and/or commonalities regarding the diving physiology and ecology of marine predators, and (ii) what are the main determinants and constrains that characterise the underwater behaviour of air-breathing vertebrates. This dataset is a compilation of data of several different studies carried out by different research teams in various locations and at various times. All TDRs were archival loggers that had to be retrieved to obtain the data. Thus, the animals had to be captured twice (deployment and retrieval). Details about the types of tags are listed in the dataset. Species used in the study were: Adelie Penguins Emperor Penguins King Penguins Fur Seals Southern Elephant Seals Weddell Seals

Metadata record for data from ASAC Project 915 and 2253 See the link below for public details on these projects. Our cetacean research is conducted on multidisciplinary cruises aimed at investigating environmental change and ecosystem effects. Our research approach now integrates broad scale acoustic monitoring with fine scale ecology experiments during annual surveys with AMLR. These data will allow us to connect fine scale variability with regional and circum-Antarctic processes, and eventually to understand how the dynamics of the Antarctic ecosystem and environmental change might affect the recovery of whale populations. The BROKE WEST multidisciplinary survey to be held in the 2005/2006 season will provide a large-scale simultaneously collected dataset within which to analyse the cetacean distribution, ecological and acoustic data. These sightings were made on Australian Antarctic Division voyages. For further information about these voyages, see the URL given below. Codes provided in the download file for voyage come in two formats: V70102 - Voyage 7 of the 2001/2002 season KK0102 - Use of the Kapitan Khlebnikov by the Australian Antarctic Division in the 2001/2002 season. The download file will include an excel spreadsheet of sightings, resightings and incidental sightings, as well as an explanatory word document. For further details on methods used, and an explanation of the types of data collected, see the above mentioned word document. These data were collected as part of ASAC projects 915 and 2253 (ASAC_915 and ASAC_2253).
