Bathymetric Data Collection for Larimore Dam in North Dakota, August 2020 Bathymetric Data Collection for Larimore Dam in North Dakota, August 2020
Data were collected in August, 2020 to support development of a bathymetric map for Larimore Dam in Grand Forks County, North Dakota. Global Navigation Satellite System (GNSS) surveying equipment was used in static and real-time kinematic (RTK) mode to establish a local reference mark and check-in/check-out point, to collect water surface elevations, and to collect topographic points...
OFR 2021-1008 MODEL OUTPUT: Soil-Water-Balance net infiltration and irrigation water use output datasets for the Mississippi Embayment Regional Aquifer System, 1915 to 2018 OFR 2021-1008 MODEL OUTPUT: Soil-Water-Balance net infiltration and irrigation water use output datasets for the Mississippi Embayment Regional Aquifer System, 1915 to 2018
This data release includes four sets of gridded annual net infiltration (groundwater recharge) and irrigation water use data sets for the Mississippi Embayment Regional Aquifer System (MERAS).Also included are gridded water balance component data sets of precipitation, runoff, actual evapotranspiration, and soil-water storage for 2000 to 2018. The net infiltration, irrigation, runoff...
Microbial Nutrient Cycling in the Upper Floridan Aquifer Microbial Nutrient Cycling in the Upper Floridan Aquifer
Groundwater samples were collected from a South Florida Water Management District (SFWMD) monitoring well at the discharge point of the Kissimmee River into Lake Okeechobee between 2018 and 2019. The groundwater source was the Upper Floridan Aquifer at approximately 1,000 feet below land surface (fbls). Samples were dosed with nitrogen, phosphorus, and carbon, then sampled over a period...
