CHIRP Data from the eastern Mississippi Sound, Alabama, acquired during R/V Jenny survey JN0206 (2002)

Party of a study to explore incised valley fill from three Gulf of Mexico bays, specifically Mobile Bay, Galveston Bay, and Corpus Christi Bay, this R/V Jenny survey collected high-resolution CHIRP data in eastern Mississippi Sound, Alabama during the summer of 2002. Two companion cruises, JN0306 and JN0406, collected CHIRP data in eastern Mississippi Sound in the summers of 2003 and 2004. The goal was to use the data to identify flooding surfaces and help quantify coastal response to forcing mechanisms. This will help test the hypothesis that variations in the rate of coastal subsidence and river discharge were not the cause of the observed coastal backstepping events.

本研究旨在探究墨西哥湾三个海湾——莫比尔湾（Mobile Bay）、加尔维斯顿湾（Galveston Bay）与科珀斯克里斯蒂湾（Corpus Christi Bay）——的深切谷充填体，此次R/V Jenny号科考航次作为该研究的组成部分，于2002年夏季在阿拉巴马州密西西比湾东部采集了高分辨率CHIRP数据。另有配套航次JN0306与JN0406，分别于2003年、2004年夏季在密西西比湾东部完成了CHIRP数据采集。本次数据采集的核心目标为：利用所获数据识别海泛面，并定量解析海岸对外部驱动机制的响应过程，以此验证一项假说——海岸沉降速率与河流径流量的变化并非观测到的海岸退积事件的成因。本项目由美国国家科学基金会（NSF）资助项目EAR-0107650、美国化学学会（ACS）石油研究基金资助项目ACS-PRF 36694-G8、墨西哥湾海岸地质学会联盟以及胡克斯研究基金共同资助。
