ABSTRACT:

Field studies were conducted along the coastline of Simpson Lagoon near Prudhoe Bay, Alaska, to assess hydrological processes along an Arctic coastline. In July 2022, a transect of monitoring wells was installed and each of the five wells was equipped with a conductivity, temperature, and depth (CTD) logger to monitor water level, salinity, and temperature at fifteen-minute intervals in the subsurface. CTD loggers were also installed in the nearshore lagoon and pond adjacent to the tundra for continuous surface water measurements. Loggers were retrieved September 29, 2022.

This resource includes publication of the specific conductivity (uS/cm) and water temperature (degrees C) measurements to accompany the previously published water level data at Guimond (2023) and Guimond et al. (2023). This resource also includes publication of the pond water level, which has been corrected for barometric compensation and to the same datum as previous data publication. For more details regarding the data collection, please refer to the manuscript and data product related to this resource.

ABSTRACT:

This resource includes sediment temperature and porewater data from low-, mid-, and high-marsh sites at Wells National Estuarine Research Reserve (WNERR) in Wells, Maine USA. Multi-depth sediment temperature was collected using a T.rod.X (Alpha Mach, Canada) at depths of 0, 5, 10, 20, 50, and 100 cm at each location. Shallow monitoring wells were co-located with temperature probes and equipped with conductivity, temperature, depth (CTD) loggers (Solinst, Canada) to continuously record water pressure, conductivity, and temperature. A CTD logger was also deployed in the tidal channel/creek for periods when the WNERR water quality monitoring station was not active. Sediment temperature, monitoring well, and creek data were collected every fifteen minutes. Temperature probes were deployed on September 29, 2021 and remained in the field through September 8, 2022, with some data loss due to logger failure. CTD loggers were deployed on September 29, 2021 and collected on June 6, 2022, with some data loss due to frozen conditions and logger failure.

ABSTRACT:

This resource expands on a previously published FlexPDE code (doi: 10.4211/hs.98d4192a4f8841149e1502f82b777f69), which solves the coupled partial differential equations describing variable-density fluid flow and solute transport, and heat transfer with salinity-dependent freeze-thaw, by incorporating additional text necessary for analyzing groundwater discharge in the coastal zone. Also included are scripts for -4 degree C and -2 degree C initial surface temperature scenarios.

ABSTRACT:

This resource includes a newly developed coastal cryohydrogeological model that simultaneously solves the coupled partial differential equations describing variable-density fluid flow and solute transport, and heat transfer with salinity-dependent freeze-thaw. This code was developed using the commercial code FlexPDE. Included in this resource are the scripts and initial condition files necessary to run various sea-level rise and warming scenarios for three values of intrinsic permeability.

ABSTRACT:

This resource includes seepage meter data from two field campaigns (August 26, 2016 and Marsh 2-3, 2017) at St. Jones National Estuarine Research Reserve in Dover, Delaware. Seepage meters were used to quantify groundwater-surface water exchange between the salt marsh sediment and tidal channel. This resource includes raw data and flux calculations from 16 seepage meters over a tidal cycle.

St. Jones Data Compilation 2017
Created: Dec. 21, 2019, 9:14 p.m.
Authors: Guimond, Julia

ABSTRACT:

This resource contains various hydrological, biological, and geochemical data from St. Jones National Estuarine Research Reserve from the year 2017. These data have been used to assess how net carbon storage is influenced by interactions between crab activity, water movement, and biogeochemistry. Hydraulic conductivity was measured by slug tests; crab burrows were counted manually and casts were created with Plaster of Paris. Redox potential was collected using in-situ, multi-depth redox sensors, and water table elevation was collected using pressure sensors.

Authors: Guimond, Julia

ABSTRACT:

This resource contains water table elevation data for St. Jones National Estuarine Research Reserve in Dover, DE. Monitoring well data from within the coastal wetland captures levels from January - May, 2018; monitoring well data from wells upland of the wetland include water table elevation for March, 2017-December, 2018. The coastal wetland water table elevation data follow from Guimond, J. (2019).
