This five-year project seeks to characterize decadal scale changes in penguin and seabird populations on the Antarctic Peninsula, and to identify the factors driving these long-term changes. Two interconnected research activities are proposed: 1. Continued, long-term monitoring and censusing of penguin and seabird populations at 117 sites throughout the Antarctic Peninsula via opportunistic ship-based data collection. 2. Synthesis and quantitative analyses of datasets detailing long-term changes in five penguin and seabird species from diverse sites throughout the Antarctic Peninsula. When complete, the penguin/seabird database will incorporate data from the Antarctic Site Inventory (ASI), the CCAMLR database, the US AMLR database, the LTER database from Palmer Station, data from British and Argentine researchers, historic census data compiled by the Scientific Committee on Antarctic Research (SCAR), and, when possible, additional privately held datasets. Additional data for temperature change, sea ice coverage, the seasonal timing and intensity of human visitation, and other factors have been gathered and will be analyzed together with population trajectories within a spatially explicit framework. The research will include hierarchical statistical analyses to characterize the long-term population dynamics of several key polar species across multiple spatial scales (sites, regions, and the Peninsula). Analyses also will focus on specific subsets of the overall database to contrast visitor impacts on paired colonies, sites, and regions that share similar environmental conditions but differ in the intensity of tourism. The Broader Impacts include (1) research training and first-time Antarctic experiences for a postdoctoral researcher and several graduate students, all of whom will then be better positioned to bring their expertise in spatial and/or quantitative/theoretical ecology to bear on questions in polar research; (2) assembly and analysis of a large, multi-season database of penguin and seabird time series from the Antarctic Peninsula that will be publicly available, (3) assistance in distinguishing the impacts of tourism versus climate change on seabird populations. Under the Environmental Protocol to the Antarctic Treaty, Treaty Parties are charged with regular and effective monitoring to assess the impacts of human activities. This project will uniquely assist Parties in fulfilling this mandate.

这个为期五年的项目旨在描述南极半岛企鹅和海鸟种群的十年尺度变化，并确定驱动这些长期变化的因素。 提出了两个相互关联的研究活动：1。* 利用船载机会收集数据，在整个南极半岛的117个地点对企鹅和海鸟种群进行持续、长期的监测和普查。2.详细说明整个南极半岛不同地点五种企鹅和海鸟物种长期变化的数据集的综合和定量分析。完成后，企鹅/海鸟数据库将纳入南极现场清单（ASI）、CCAMLR数据库、美国AMLR数据库、帕尔默站的LTER数据库、英国和阿根廷研究人员的数据、南极研究科学委员会（SCAR）汇编的历史普查数据，并在可能时纳入其他私人拥有的数据集。温度变化，海冰覆盖，季节性的时间和强度的人类访问，以及其他因素的额外数据已经收集，并将在一个空间明确的框架内与人口轨迹一起进行分析。该研究将包括分层统计分析，以描述多个空间尺度（地点，地区和半岛）的几个关键极地物种的长期种群动态。分析还将侧重于整个数据库的特定子集，以对比游客对环境条件相似但旅游强度不同的成对殖民地、遗址和地区的影响。更广泛的影响包括：（1）为一名博士后研究员和几名研究生提供研究培训和首次南极经验，使他们能够更好地利用他们在空间和/或定量/理论生态学方面的专业知识来解决极地研究中的问题;（2）汇编和分析一个关于南极半岛企鹅和海鸟时间序列的大型多季数据库，并将向公众开放，（3）协助区分旅游业与气候变化对海鸟种群的影响。 根据《南极条约环境议定书》，条约缔约国负责定期和有效地监测，以评估人类活动的影响。本项目将以独特的方式协助缔约方履行这一任务。
