Carbonate chemistry, nutrient concentration, and dissolved oxygen concentration for discreet water samples collected during multiple cruises between June 2017 to Sept 2018 within Galveston Bay, TX

These data include carbonate chemistry, nutrient concentration, and dissolved oxygen concentration for discreet water samples collected within Galveston Bay, TX. Eight single day cruises were conducted quarterly aboard the R/V Lithos or R/V Trident from June 2017 through September 2018. In addition, discreet water samples were collected at sites 10 - 60 km outside the mouth of the bay and up to 15m deep to characterize incoming seawater to the bay. These samples were collected on three cruises (WTX1 - R/V Manta, WTX3 - R/V Manta, WTX4 - R/V Pelican) in June, August, and November 2017. Discreet water samples were collected for total alkalinity and dissolved inorganic carbon, dissolved oxygen, and dissolved nutrients. CTD profiles were collected at each sampling site. Stochastic coastal acidification events in response to high volume rainfall and runoff that often accompanies tropical cyclone events has the potential to represent a significant threat to valuable calcifying reef ecosystems. Understanding acidification response and recovery to such events is critical to improving conservation and protection of coastal ecosystems, like oyster and coral reefs, particularly as climate change continues and tropical cyclone rainfall intensity increases. These data assess the impact of the rainfall and runoff from Hurricane Harvey on the acidification levels in Galveston Bay, TX. Samples were collected and analyzed primarily by Tacey Hicks, with assistance from other students in Dr. Katie Shamberger ’s research group, at Texas A&M University.本数据集包含采自得克萨斯州加尔维斯顿湾（Galveston Bay）内的离散水样的碳酸盐化学参数、营养盐浓度与溶解氧浓度。2017年6月至2018年9月间，研究团队依托R/V Lithos号与R/V Trident号科考船，按季度开展了8次单日巡航作业。此外，为表征输入该湾的外海海水特征，团队在湾口外10至60公里、水深不超过15米的站位采集了离散水样。上述外海水样分别于2017年6月、8月及11月，通过WTX1（R/V Manta号科考船）、WTX3（R/V Manta号科考船）与WTX4（R/V Pelican号科考船）三次航次完成采集。本次采集的水样用于分析总碱度、溶解无机碳、溶解氧与溶解态营养盐，所有采样站位均同步采集了CTD（Conductivity-Temperature-Depth，温盐深）剖面数据。 热带气旋伴随的强降雨与径流可引发随机近岸酸化事件，此类事件对具有重要生态价值的钙化礁生态系统构成显著威胁。明确此类酸化事件下生态系统的响应与恢复机制，对于优化牡蛎礁、珊瑚礁等近岸生态系统的保护与管理工作至关重要——尤其在气候变化持续、热带气旋降雨强度不断升高的背景下。本数据集用于评估飓风哈维（Hurricane Harvey）引发的降雨与径流对得克萨斯州加尔维斯顿湾酸化水平的影响。本批水样主要由Tacey Hicks完成采集与分析，得到了得克萨斯农工大学（Texas A&M University）Katie Shamberger博士研究团队其他学生的协助。
