The marsh is located landward of Seven Mile Island, a populated barrier island in Cape May County, New Jersey, and is a part of the Seven Mile Island Innovation Laboratory (SMIIL), a research initiative focused on advancing dredging and marsh restoration practices. Data were collected using In-Situ Aqua TROLL 600 multiparameter sondes, which were cleaned, recalibrated, and swapped every 4–12 weeks to enable continuous monitoring. Turbidity and chlorophyll a data are included but have highly variable coverage. The dataset comprises 18 deployments, which have been appended and quality controlled. Meteorological data (air temperature, relative humidity, atmospheric pressure) from a centrally located Young ResponseONE Weather Transmitter and Onset HOBO water level logger, along with ERA5 wind speed data, are provided for the same time period. This high-resolution, multi-year dataset supports the analysis of aquatic ecosystem metabolism and environmental variability in a marsh-dominated estuary, a system type that remains underrepresented in long-term, high-frequency monitoring efforts.\n\ncdm_data_type = Other\nVARIABLES:\ntime (Datetime_utc, seconds since 1970-01-01T00:00:00Z)\nsite (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\ndepth (m)\nsalinity (psu)\ntemperature (degrees Celsius)\nDOconc (μmol/L)\nDOsat (percent (%))\npH (pH Scale)\nchla (Relative Fluorescence Units (RFU))\nturbidity (Nephelometric Turbidity Unit (NTU))\nTair (degrees Celsius)\nrhumid (percent (%))\npatm (hPa)\nwspd (m/s)\n | BCO-DMO | bcodmo_dataset_971943_v1 |
