Estuarine Living Marine Resources: Southeast Regional Distribution and Abundance (NCEI Accession 0163992)

This is the original (1991) Southeast regional component of NOAA's Estuarine Living Marine Resources (ELMR) Project, a national database of ecologically and economically important fishes and invertebrates in the Nation's estuaries. The distribution and relative abundance are depicted in a consistent format for 40 species of fishes and invertebrates, in 20 estuaries in coastal North Carolina, South Carolina, Georgia, and the east coast of Florida. Species were selected according to a set of criteria, which consider their commercial, recreational, and ecological value. For each species, five life stages are considered - adults, juveniles, larvae, spawning, and eggs - with some exceptions based on individual species life history. Each estuary is subdivided into one to three salinity zones (Tidal Fresh, Mixing, and Seawater). Relative abundance was ranked on a five-tier scale by month for each life stage of each species, in each salinity zone of each estuary. Details of the methods for the original Southeast ELMR component can be found in Nelson et al. (1991) and Nelson and Monaco (2000).本数据集为美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）河口活体海洋资源（Estuarine Living Marine Resources, ELMR）项目1991年东南区域原始组成部分，该项目是全美河口内兼具生态与经济价值的鱼类及无脊椎动物的国家级数据库。针对北卡罗来纳州沿海、南卡罗来纳州、佐治亚州及佛罗里达州东海岸的20处河口，本数据集以统一格式呈现了40种鱼类及无脊椎动物的分布与相对丰度。物种遴选遵循一套综合考量其商业价值、休闲垂钓价值与生态价值的评判标准。针对每个物种，本数据集涵盖5个生命阶段：成体、稚鱼、幼体、产卵期与卵期，部分物种会依据其自身生活史存在例外情况。每处河口被划分为1至3个盐度分区：潮汐淡水区（Tidal Fresh）、混合水区（Mixing）与海水区（Seawater）。针对每个河口各盐度分区内的每个物种的各生命阶段，相对丰度按月度以五级分级标准进行评定。原始东南区域ELMR项目组分的方法学细节可参阅Nelson等人（1991年）以及Nelson与Monaco（2000年）的相关文献。
