Comparative Diving Ecology Across Southern Ocean Marine Predators - Seals and Penguins

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本研究由朱利娅·龙孔（Giulia Roncon）在其于IMAS攻读博士学位期间完成。研究整合了档案数据与当代潜水数据，这些数据由南大洋南极东部海域的6种海洋捕食者（3种企鹅与3种海豹）采集所得，旨在阐明两大核心科学问题：其一，海洋捕食者的潜水生理学与生态学存在哪些差异与共性？其二，决定呼吸空气的脊椎动物水下行为的主要影响因素与限制条件是什么？ 本数据集整合了多个研究团队在不同地点、不同时段开展的多项研究的数据。所有时间深度记录仪（Time-Depth Recorders, TDRs）均为需回收方可获取数据的档案式记录器，因此实验动物需被捕获两次，分别用于设备的部署与回收。关于记录器的具体类型细节已在数据集内列明。 本研究使用的物种包括：阿德利企鹅、帝企鹅、王企鹅、海狗、南象海豹、威德尔海豹。
