Survey Lines along which seismic data were collected aboard R/V RAFAEL (field activities 05001 and 06001) in Apalachicola Bay, FL (SEISMICLINES)

These data were collected under a cooperative mapping program between the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration Coastal Services Center (NOAA\CSC), and the Apalachicola National Estuarine Research Reserve (NERR). The primary objectives of this program were to collect marine geophysical data to develop a suite of seafloor maps to better define the extent of oyster habitats, the overall seafloor geology of the bay and provide updated information for management of this resource. In addition to their value for management of the bay's oyster resources, the maps also provide a geologic framework for scientific research and the public.
High-resolution bathymetry, backscatter intensity, and seismic profile data were collected over 230 square kilometers of the floor of the bay. The study focused on the Apalachicola Bay and Western St. George Sound portions of the estuary in mostly in depths > 2.0 meters.

这些数据由美国地质调查局（U.S. Geological Survey, USGS）、美国国家海洋和大气管理局海岸服务中心（National Oceanic and Atmospheric Administration Coastal Services Center, NOAACSC）以及阿巴拉契科拉国家河口研究保护区（Apalachicola National Estuarine Research Reserve, NERR）合作开展的测绘项目采集所得。本项目的核心目标为采集海洋地球物理数据，以生成系列海底地图，从而更精准地界定牡蛎栖息地的分布范围、明确海湾整体的海底地质状况，并为该资源的管理提供更新后的参考信息。除助力海湾牡蛎资源的管理工作外，这些地图还可为科学研究与公众提供地质框架参考。
本次采集的高分辨率水深测量数据、反向散射强度数据及地震剖面数据覆盖了该海湾230平方千米的海底区域。研究重点聚焦于河口的阿巴拉契科拉湾与圣乔治湾西部水域，作业水深大多大于2.0米。
