Seagrass density and biomass, and related data from seagrass monitoring station LM-151 in Laguna Madre Texas from 1989-03-24 to 2022-06-23 (NCEI Accession 0282643)

This dataset contains raw sampling data beginning in 1989 for a long-term environmental and seagrass monitoring station in Laguna Madre (“LM-151”). This project served to understand environmental drivers of long-term changes in seagrass condition within the Upper Laguna Madre, Texas. Environmental parameters measured within the water column include water depth, dissolved oxygen concentration, underwater light level, pH, salinity, Secchi depth (turbidity), water temperature, total suspended solids, and dissolved inorganic nitrogen and ammonium. Seagrass biological parameters measured are above/belowground biomass and shoot density. Typical seagrass species represented within the data include Halodule wrightii (shoal grass) and Syringodium filiforme (manatee grass). Sampling was dependent on funding/resource availability and local weather conditions, therefore temporal gaps in data may exist. Data are provided in CSV format.

该数据集包含始于1989年的原始采样数据，来源于拉古纳 madre（“LM-151”）的长期环境与海草监测站。该项目旨在探究得克萨斯州上拉古纳 madre区域内海草状况长期变化的环境驱动因素。水体中测量的环境参数包括水深、溶解氧浓度、水下光照水平、pH值、盐度、塞奇深度（浊度）、水温、总悬浮物，以及溶解性无机氮与铵盐。测量的海草生物参数包括地上/地下生物量及株密度。数据中包含的典型海草物种有Halodule wrightii（shoal grass）和Syringodium filiforme（manatee grass）。采样受资金/资源可用性及当地天气条件影响，因此数据中可能存在时间间隙。数据格式为CSV。
