Delta-X: Total Suspended Solids Concentration across MRD, LA, USA, 2021, Version 2

This dataset provides measurements of total suspended solids concentrations (TSS) of surface waters in the Atchafalaya River and Terrebonne Basins during the spring (2021-03-25 to 2021-04-22) and fall (2021-08-14 to 2021-09-24) field efforts by the Delta-X project. Field sampling was paused on August 25 and resumed on September 13, 2021, due to the landfall of Hurricane Ida on 2021-08-26 approximately 70 km east of the study site. Water quality changes caused by the hurricane were expected to be minimal. Samples were collected from ~0.5 m of surface in multiple channels of varying width (from a few meters to >100 m), near Delta-X intensive study sites, in open bays and lakes, and at few locations in the nearshore Gulf of Mexico. For each collection, the water sample volume was filtered, and the suspended particles retained on the filter were weighed after drying. The TSS concentration was calculated as the difference of the filter weight (before and after filtration) divided by the volume filtered.

本数据集提供了阿查法拉亚河和特雷博恩流域地表水体中总悬浮固体浓度（TSS）的测量数据。这些数据是在Delta-X项目春季（2021年3月25日至2021年4月22日）和秋季（2021年8月14日至2021年9月24日）的实地考察期间收集的。由于2021年8月26日飓风Ida在研究地点以东约70公里的登陆，实地采样于8月25日暂停，并于2021年9月13日恢复。预计飓风引发的水质变化将微乎其微。样品从多个不同宽度的渠道（从几米到超过100米）的约0.5米深处的地表水中采集，这些渠道位于Delta-X密集研究区域附近、开放海湾和湖泊以及墨西哥湾近岸的少数地点。对于每次采集，水样体积经过过滤，干燥后称量过滤上保留的悬浮颗粒。TSS浓度通过过滤前后滤纸重量之差除以过滤体积来计算。
