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 PenguinsEmperor PenguinsKing PenguinsFur SealsSouthern Elephant SealsWeddell Seals

本研究由朱利娅·龙孔（Giulia Roncon）开展，系其在IMAS攻读博士学位期间的研究内容。本研究结合档案数据与当代潜水数据展开，相关数据由六种海洋捕食者（三种企鹅与三种海豹）在南大洋南极东部海域采集所得，旨在厘清两大核心科学问题：其一，海洋捕食者的潜水生理学与生态学特征是否存在差异与共性；其二，决定并制约呼吸空气脊椎动物水下行为的主要因素与限制条件是什么。
本数据集为多份独立研究的数据汇编，这些研究由不同科研团队在不同地点、不同时段完成。所有TDR（时间深度记录仪，Time-Depth Recorder）均为需回收方可获取数据的档案式记录器，因此研究对象需被捕获两次，分别用于设备的部署与回收。关于标签类型的详细信息已收录于本数据集内。
本研究涉及的物种包括：阿德利企鹅（Adelie Penguins）、帝企鹅（Emperor Penguins）、王企鹅（King Penguins）、海狗（Fur Seals）、南象海豹（Southern Elephant Seals）、威德尔海豹（Weddell Seals）
