9809161 KOOYMAN The habitat conditions and distribution patterns of emperor penguin foraging in the Ross Sea during winter are unknown. This must be one of the most extreme environments within which any species of bird searches for food. Working from the research vessel Nathaniel B. Palmer a preliminary study of these aspects of emperor penguin natural history will be initiated. Distribution patterns of emperors and other vertebrate species will be determined along the cruise track. Single sample diet analysis of up to twenty foraging birds will be conducted at various segments of the cruise. The travel characteristics and diving patterns of four adult birds will be determined using satellite telemetry. The results of these observations should provide an initial picture of the preferred prey and foraging areas of birds that inhabit the Ross Sea. In addition, a spring census of the colonies of the Ross Sea is proposed to assess if the earlier perturbations of the past years El Nino significantly affected the following years breeding success.

9809161 KOOYMAN冬季在罗斯海觅食的帝企鹅的栖息地条件和分布模式尚不清楚。 这一定是任何鸟类寻找食物的最极端的环境之一。 在研究船纳撒尼尔B号上工作。帕默博士将开始对帝企鹅自然史的这些方面进行初步研究。 将沿着巡航轨迹确定帝王蝶和其他脊椎动物物种的分布模式。 将在巡航的各个部分对多达20只觅食鸟类进行单一样本饮食分析。 将利用卫星遥测技术确定四只成年鸟的旅行特征和潜水模式。 这些观察的结果应该提供了一个初步的图片的首选猎物和觅食地区的鸟类栖息在罗斯海。 此外，建议对罗斯海的殖民地进行春季人口普查，以评估过去几年厄尔尼诺现象的早期扰动是否显著影响了接下来几年的繁殖成功。
