SIO Marine Bird and Mammal Survey 2003

Original provider: David Hyrenbach Dataset credits: National Science Foundation Abstract: In January 2003, investigators from Duke Marine Lab (David Hyrenbach) and CUNY-Staten Island (Richard Veit) embarked on a research cruise spanning the Southern Indian Ocean, from La Reunion Island, to the French territories of Crozet, Kerguelen and Amsterdam, and finishing in Perth, Western Australia. During this cruise, we surveyed marine birds and mammals across a large-scale gradient of ocean productivity and water mass characteristics, spanning from tropical to sub-Antarctic waters (from 21 to 49 degrees S). Purpose: This cruise is part of an interdisciplinary project, in collaboration with George Hunt (University of California at Irvine), Henri Weimerskirch (CNRS-CEBC), and Nicolas Metzl (Institut Pierre Simon Laplace), to understand the way oceanographic variability influences the dispersion and community structure of upper-trophic marine predators in the Southern Indian Ocean. Supplemental information: The data presented here are marine bird and mammal counts averaged into contiguous 9-km transects. This cruise, was funded and supported by the following agencies: The U.S. National Science Foundation Office of Polar Programs (http://www.nsf.gov/home/polar/), the French Polar Institute (http://www.ifremer.fr/ifrtp/), and the French Ocean Indien Service 'Observation(http://www.ipsl.jussieu.fr/services/Observations/fr/OISO.htm).

摘要：2003年1月，杜克大学海洋实验室（Duke Marine Lab）的David Hyrenbach与纽约市立大学斯塔滕岛分校（CUNY-Staten Island）的Richard Veit开展了一场横跨南印度洋的科考巡航，航线从留尼汪岛出发，途经法属克罗泽群岛、凯尔盖朗群岛与阿姆斯特丹群岛，最终终止于西澳大利亚州珀斯。本次巡航沿海洋生产力与水团特征的大尺度梯度开展海鸟与海洋哺乳动物调查，覆盖热带至亚南极海域（南纬21°至49°）。
研究目的：本巡航属于一项跨学科研究项目的组成部分，该项目与加州大学欧文分校（University of California at Irvine）的George Hunt、法国国家科学研究中心-生物与生态研究中心（CNRS-CEBC）的Henri Weimerskirch以及皮埃尔·西蒙·拉普拉斯研究所（Institut Pierre Simon Laplace）的Nicolas Metzl合作，旨在阐明海洋学变异性如何影响南印度洋上层营养级海洋捕食者的扩散过程与群落结构。
补充说明：本次公开的数据集为按连续9公里样带平均统计的海鸟与海洋哺乳动物种群数量。本巡航由以下机构资助支持：美国国家科学基金会极地项目办公室（http://www.nsf.gov/home/polar/）、法国极地研究所（http://www.ifremer.fr/ifrtp/）以及法国印度洋海洋观测服务（http://www.ipsl.jussieu.fr/services/Observations/fr/OISO.htm）。
