The Marine Environmental Sciences Consortium (MESC) is Alabama's maine science research and education center. Founded in 1971, MESC includes 21 colleges and universities and is part of the state's system of higher education. Teaching and research activities of the MESC take place principally at the Dauphin Island Sea Lab (DISL), a 36 acre campus located on Dauphin Island, 30 miles south of Mobile, Alabama. Here resident MESC faculty, scientists from MESC member schools and visiting investigators carry out individual and cooperative research efforts. Research activities at the MESC are currently centered on understanding (1) the relative importance of salt marsh, seagrass and unvegetated bottom habitats to the production of fishes and invertebrates in nearshore waters in the northern Gulf of Mexico, and on (2) exchanges of energy between estuaries and the open Gulf waters, with special attention given to understanding the influence of estuarine waters on the productivity of offshore "hard bottom" fishing grounds. To further enhance the growing research program at the MESC and to stimulate additional interactions with visiting scientists, this project provides funds for the purchase of a Carbon/Nitrogen/Sulfur (CNS) analyzer, a high-speed refrigerated centrifuge, and high capacity ultra-low temperature freezer. These items are essential to the continued growth of the process-oriented component of the MESC research program. The CNS analyzer is indispensable for measuring the total carbon, nitrogen and sulfur composition of particulate organic matter. The addition of CNS capabilities will facilitate the development of projects aimed at understanding the relative importance of natural inorganic and organic nutrient additions to estuaries compared with those caused by man's activities. The addition of the refrigerated centrifuge and ultra-low freezer will make possible several pending research projects designed to examine chemically-mediated responses during larval recruitment and feeding in estuarine and near-coastal environments.

海洋环境科学联盟(MESC)是阿拉巴马州缅因州的科学研究和教育中心。MESC成立于1971年，包括21所学院和大学，是该州高等教育系统的一部分。MESC的教学和研究活动主要在Dauphin Island Sea Lab(DISL)进行，这是一个占地36英亩的校园，位于阿拉巴马州莫比尔以南30英里的Dauphin岛上。在这里，MESC常驻教职员工、MESC成员学校的科学家和访问调查人员开展个人和合作研究工作。MESC的研究活动目前集中在了解(1)盐沼、海草和无植物的海底生境对墨西哥湾北部近岸水域鱼类和无脊椎动物生产的相对重要性，以及(2)河口和墨西哥湾开阔水域之间的能量交换，特别注意了解河口水域对近海“硬底”渔场生产力的影响。为了进一步加强MESC不断增长的研究计划，并促进与来访科学家的更多互动，该项目为购买碳/氮/硫(CNS)分析仪、高速冷冻离心机和高容量超低温冷冻机提供资金。这些项目对于MESC研究计划中面向过程的部分的持续增长至关重要。CNS分析仪是测量颗粒有机物的总碳、氮和硫组成不可缺少的仪器。CNS能力的增加将有助于开展旨在了解与人类活动造成的营养相比，天然无机和有机营养物质对河口的相对重要性的项目。冷藏离心机和超低冷冻机的加入将使几个悬而未决的研究项目成为可能，这些项目旨在检查河口和近海环境中幼虫招募和取食过程中的化学调节反应。
