The Plum Island Ecosystems (PIE) LTER is an integrated research, education and outreach program whose goal is to develop a predictive understanding of the long-term response of watershed and estuarine ecosystems at the land-sea interface to changes in climate, land use and sea level. The principal study site is the Plum Island Sound estuary, its coupled Parker, Rowley and Ipswich River watersheds and the adjacent coastal ocean, the Gulf of Maine. Humans are altering the ecosystems of the world at rates not previously experienced. Understanding and predicting how multiple stresses affect the sustainability of ecosystems is one of the most crucial challenges in environmental biology. The PIE LTER focuses on how several aspects of global change influence organic matter and inorganic nutrient biogeochemistry and estuarine food-webs. The inputs of organic matter and nutrients from land, ocean and marshes interact with the external drivers (climate, land use, river discharge, sea level) to dictate the extent and degree of nutrient and organic matter processing and determine the spatial patterns of estuarine productivity and trophic structure. The overarching question is: How will trophic structure and primary and secondary productivity in estuaries be affected by changes in organic matter and nutrient loading and hydrodynamics caused by changing land use, climate and sea level? The project uses a combination of approaches to address research questions and hypotheses: 1) short- and long-term core measurements; 2) short and long-term experiments; 3) comparative ecosystem studies; and 4) modeling. The research integrates estuarine biogeochemistry with studies of food webs and population biology of all trophic levels. The PIE LTER data and information system provides a centralized network of information and data related to the Plum Island Sound Estuarine Ecosystem and its watersheds. This network provides researchers associated with PIE-LTER access to common information and data in addition to centralized long-term storage. Data and information are easily accessible to PIE-LTER scientists, local, regional, state partners and the broader scientific community. Researchers associated with PIE-LTER are committed to the integrity of the information and databases resulting from the research. Broader Impacts: PIE-LTER has developed links with local teachers and students, citizens, conservation organizations, and local, state and federal agencies. What started out as a minimalist program has grown to be a broad, well-rounded suite of activities. The education/outreach program is expected to further expand during this next awqard period, as additional support is obtained from other federal agencies, the Commonwealth of Massachusetts, and private foundations. The long-term goal is to establish a Coastal Outreach office at the PIE-LTER study site that will serve to integrate and promote interactions with interested parties throughout New England. During this grant period, the PIE-LTER will expand its schoolyard program to provide on-going professional development for teachers; support the expansion of this project into nearby urban areas including Salem, Boston, and Revere; and facilitate the transfer of this program to New Hampshire and Maine via the Gulf of Maine Institute. There will be greater involvement with undergraduate and graduate education with the addition of PIs Mather and Pontius from UMass and Clark University, respectively. PIE-LTER has a very active outreach program in which the goal is to communicate research findings to individuals,

Plum Island生态系统（PIE）LTER是一项综合研究，教育和外展计划，其目标是对土地海界面对气候，土地使用和海平面变化的分水岭和河口生态系统的长期反应进行预测理解。主要研究地点是梅花岛河口，其耦合的帕克，罗利和伊普斯维奇河流域以及缅因州湾邻近的沿海海洋。人类正在以以前从未经历过的速度改变世界的生态系统。理解和预测多种压力如何影响生态系统的可持续性是环境生物学中最关键的挑战之一。馅饼的重点是全球变化的几个方面如何影响有机物和无机营养生物地球化学和河口食品 - 野生动物。陆地，海洋和沼泽的有机物和养分的输入与外部驱动因素（气候，土地利用，河流排放，海平面）相互作用，以决定养分和有机物加工的程度和程度，并确定河口生产力和营养结构的空间模式。总体问题是：河口中的营养结构和初级和次要生产力将如何受到有机物的变化以及养分负荷的变化以及由土地使用，气候和海平面变化引起的流体动力学的影响？该项目结合了方法来解决研究问题和假设：1）短期和长期核心测量； 2）短期和长期实验； 3）比较生态系统研究； 4）建模。该研究将河口生物地球化学与食物网和所有营养水平的种群生物学研究相结合。 PIE lter数据和信息系统提供了与Plum Island Sound Estuarine生态系统及其流域有关的信息和数据的集中式网络。该网络可为研究人员提供与派对访问常见信息和数据相关的研究人员，除了集中式的长期存储。馅饼科学家，地方，地区，州伙伴和更广泛的科学界很容易访问数据和信息。与PIE-LETER相关的研究人员致力于研究所产生的信息和数据库的完整性。更广泛的影响：Pie-lter已与当地的教师和学生，公民，保护组织以及地方，州和联邦机构建立了联系。最初是一项简约的计划已经成为一套广泛的，全面的活动。随着其他联邦机构，马萨诸塞州联邦和私人基金会获得的额外支持，预计教育/外展计划将在下一个AWQARD期间进一步扩展。长期的目标是在派林研究地点建立沿海外展办公室，该办公室将有助于整合和促进与新英格兰各地有关方面的互动。在这一赠款期间，Pie-lter将扩大其校园计划，为教师提供持续的专业发展；支持该项目扩展到附近的城市地区，包括塞勒姆，波士顿和里维尔；并通过缅因州湾促进该计划将该计划转移到新罕布什尔州和缅因州。分别增加了UMass和Clark University的PIS Mather和Pontius，将有更大的参与本科和研究生教育。 Pie-lter有一个非常活跃的外展计划，其目标是向个人传达研究结果，
