Nutrient and trace element results for the U.S. Geological Survey vernal ponds study, Pleasant Grove, New Jersey, 2022-23 This data release contains the concentration results for basic water-quality constituent class parameters (water temperature, pH, turbidity, and specific conductance), total nitrogen, total phosphorous, chloride, and trace elements in surface-water samples collected from two subsites within two vernal pools near Pleasant Grove, New Jersey in 2022-23. In the winter (December 2022 and February 2023) samples were collected at opposing ends of the ponds, or wherever ponding was sufficient for a sample to be taken. An additional sample was collected in July 2023 during the amphibian breeding season. The number of samples collected during each sampling event varied based on water availability and in July 2023 only one...

The database provides information for each withdrawal point including estimated location and completion interval (Moreo and others, 2003). Groundwater withdrawal estimates for each withdrawal point have been compiled by water use and year. Uncertainty was assigned to the annual withdrawal values based on the use and method of estimation (Moreo and others, 2003)....

The files within the field-measured channel incision folder include 1) a point file of original survey locations with a description of channel characteristics and 2) a stream network file with the field-surveyed degree of channel incision classified by stream reach. The file within the model-predicted channel incision folder includes stream networks for each watershed, and the incision prediction from lidar for the years 2002, 2008, 2013, and 2018.

More than half of the thickness of the aquifer system is composed of fine-grained sediments, including clays, silts, and sandy or silty clays that are susceptible to compaction.

The lifespan calculation is based on estimated sediment supply and sea-level rise (SLR) predictions after Ganju and others (2020). Sea level predictions are local estimates which correspond to the 0.3, 0.5, and 1.0 meter increase in Global Mean Sea Level (GMSL) scenarios by 2100 from Sweet and others (2022).

Annual median nitrate values were computed for PSWs throughout the SJV during the period of study. Median annual nitrate values were calculated at all PSWs with available data in the SJV, resulting in a total of 698 PSWs with complete annual records after single-year linear gap imputation.
