    "title": "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)",
    "description": "This dataset contains raw sampling data beginning in 1989 for a long-term environmental and seagrass monitoring station in Laguna Madre (\u201cLM-151\u201d). 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.",
