Sidescan sonar polyline shapefile of trackline navigation files collected by the U.S. Geological Survey in the Madison Swanson and Steamboat Lumps Marine Protected Areas, Gulf of Mexico in 2000 (Geographic, WGS 84)

The U.S. Geological Survey (USGS) mapped approximately 22 square miles of the Madison Swanson Marine Protected Area (MPA) and Steamboat Lumps MPA, which are located on the Florida shelf edge in the northeastern Gulf of Mexico in 2000 using sidescan sonar and high-resolution chirp seismic-reflection systems. This survey was conducted as part of a larger study of the effectiveness of no-fishing reserves in protecting grouper spawning aggregations. Field activity information for this cruise is available on-line through the U.S. Geological Survey Coastal and Marine Geoscience Data System at http://cmgds.marine.usgs.gov/fan_info.php?fa=2000-005-FA.

美国地质调查局（U.S. Geological Survey，USGS）于2000年采用侧扫声呐与高分辨率啁啾地震反射系统，完成了位于墨西哥湾东北部佛罗里达陆架边缘的麦迪逊·斯旺森海洋保护区（Madison Swanson Marine Protected Area，MPA）与蒸汽船岩礁海洋保护区（Steamboat Lumps MPA）共计约22平方英里海域的测绘工作。本次调查是针对禁渔保护区保护石斑鱼产卵集群有效性的大型研究的组成部分。本次航次的野外作业相关信息可通过美国地质调查局海岸与海洋地质科学数据系统（U.S. Geological Survey Coastal and Marine Geoscience Data System）在线查询，具体网址为http://cmgds.marine.usgs.gov/fan_info.php?fa=2000-005-FA。
