The Palmer Long-Term Ecological Research (LTER) is a multidisciplinary project focused on the marine pelagic ecosystem west of the Antarctic Peninsula, one of most rapidly warming regions on the planet. The research will undertake a synthesis of zooplankton and micronekton data collected from 1991 through 2008 as part of this program, specifically to investigate spatio-temporal variability on multiple scales and to test hypotheses on the underlying causes of the variability documented. Data include community composition, abundance and biomass, from net tows and bioacoustic transects; and life history information for both Antarctic krill and the salp (Salpa thompsoni), the biomass dominants for zooplankon 2 mm. In addition, in situ rates of secondary production (growth, spawning and egg production) are available for the key species Antarctic krill. This zooplankton data set combined with the coherent multi-disciplinary data sets collected by the Palmer LTER is uniquely suited for studies of spatio-temporal variability and mechanisms underlying that variability, partially due to the fact that the time period spans three full cycles of recruitment in Antarctic krill and variability in primary production. Included are resources for multiple data base activities: completion of sample analysis and data submittal for the 0708 field season, interactions with the Palmer LTER information manager, and submittal to the LTER data directory of completed derived products as described above. Synthetic activities will formally establish collaborations with both national and international partners. In addition to published scientific articles, both raw and synthetic data will be archived with metadata. Such data are essential for ecosystem exploration, modeling efforts and ecosystem-based fisheries management underway in the Commission for the Conservation of Antarctic Marine Living Resources. Larval fish samples will be inventoried and shipped to the Smithsonian Institution, National Museum of Natural History to complete our effort to ensure the Palmer LTER zooplankton samples are available to other investigators in the future. Educational efforts include the training and mentoring of a graduate student (Master's level) and three undergraduate students.

帕尔默长期生态研究是一个多学科项目，重点是南极半岛以西的海洋水层生态系统，该半岛是地球上变暖最快的地区之一。作为该计划的一部分，该研究将对1991年至2008年收集的浮游动物和微浮游生物数据进行综合，特别是在多个尺度上调查时空变化，并测试关于记录的变化的根本原因的假设。数据包括来自网拖和生物声断面的群落组成、丰度和生物量;南极磷虾和Salpa thompsoni（Salpa thompsoni）的生活史资料，这两种鱼的生物量是2毫米上动物园的主要生物量。这一浮游动物数据集与帕尔默LTER收集的连贯的多学科数据集相结合，非常适合研究时空变异性和这种变异性背后的机制，部分原因是时间段跨越了南极磷虾招募的三个完整周期和初级生产的变异性。包括用于多个数据库活动的资源：完成0708野外季节的样本分析和数据提交、与Palmer LTER信息经理的交互以及将如上所述的已完成衍生产品提交到LTER数据目录。 综合活动将与国家和国际伙伴正式建立合作关系。除了已发表的科学文章外，原始数据和合成数据都将与元数据一起存档。这些数据对于南极海洋生物资源保护委员会正在进行的生态系统探索、建模工作和基于生态系统的渔业管理至关重要。仔鱼样本将被清点并运往史密森学会，国家自然历史博物馆，以完成我们的努力，以确保帕尔默LTER浮游动物样本可供其他研究人员在未来。教育工作包括培训和指导一名研究生（硕士一级）和三名本科生。
