NCCOS Assessment: An Aquaculture Opportunity Atlas for the U.S. Gulf of Mexico (NCEI Accession 0285913)

Shapefiles of the Aquaculture Opportunity Area (AOA) study developed during 2021 for the Gulf of Mexico. Included in this dataset are: (1) Study areas in the Gulf of Mexico developed based on depth, jurisdictional boundaries, and Level III biogeographical breaks. (2) Compiled observations of Harmful Algal Blooms (Karina brevis) from 2000 to 2018 in the Gulf of Mexico and eastern Florida. (3) Suitability modeling results for the West, Central, East, and Southeast Gulf of Mexico study areas are presented as categories (“Unsuitable,” “Low,” “Moderate,” “High”) based on ocean use and conservation concerns, including: national security, natural and cultural resources, industry, navigation, transportation, aquaculture, and fishing. (4) High-High clusters (HH) identified as the most suitable areas from LISA (Local Index of Spatial Association) analysis. (5) Refined HH clusters that could accommodate at least one 500-acre AOA option. (6) Highest ranking options for each of the refined HH clusters representing a 500- to 2000-acre area between 50 to 150 meters depth that has relatively high suitability for generalized marine aquaculture based on a within cluster model evaluating logistics, vessel traffic, commercial fishing, and oceanography data. (7) Location and areal extent of options identified for each study region meeting a dispersion rule (greater than 30 nautical miles distance between locations).2021年针对墨西哥湾开展的水产养殖潜力区（Aquaculture Opportunity Area, AOA）研究的矢量图层文件（Shapefiles）。本数据集包含以下内容： 1. 基于水深、管辖边界及三级生物地理分区界线划定的墨西哥湾研究区域； 2. 2000年至2018年墨西哥湾及佛罗里达东部海域的Karina brevis（标准学名为Karenia brevis，即短卡伦藻）有害藻华（Harmful Algal Blooms, HABs）观测数据汇编； 3. 针对墨西哥湾西部、中部、东部及东南部研究区域开展的适宜性评价建模结果，基于海洋利用与保护考量因素（涵盖国家安全、自然与文化资源、产业、航海、运输、水产养殖及渔业），划分为“不适宜”“低适宜”“中等适宜”“高适宜”四个等级； 4. 基于局部空间关联指数（Local Index of Spatial Association, LISA）分析识别出的高-高聚集区（High-High clusters, HH），即最适宜的区域； 5. 经精细化处理的HH聚集区，其可至少容纳一处500英亩的AOA备选地块； 6. 针对每个精细化HH聚集区的最优备选地块：该地块位于水深50至150米之间、面积500至2000英亩的海域，基于集群内物流、船舶交通流量、商业捕捞及海洋学数据评估模型，其对通用海洋水产养殖具有较高适宜性； 7. 各研究区域内符合分散性规则（地块间距离大于30海里）的备选地块的位置与范围。
