Water level, salinity, and elevation data at Turtle Bayou Mitigation Area of Bayou Sauvage National Wildlife Refuge, 2025 (ver. 2.0, January 2026) Water level, salinity, and elevation data at Turtle Bayou Mitigation Area of Bayou Sauvage National Wildlife Refuge, 2025 (ver. 2.0, January 2026)
Bayou Sauvage National Wildlife Refuge (BSNWR) is an urban refuge in southeastern Louisiana that has been altered extensively due to human impacts. As a result, the hydrology of the impounded (interior) marshes within the BSNWR has been disrupted due to obstructions such as spoil banks, levees, and water control structures that affect the gradient and fluctuation of water surface...
Nutrient balances, river loads, and a counterfactual analysis to determine drivers of Mississippi River nitrogen and phosphorus loads from 1975 to 2017 Nutrient balances, river loads, and a counterfactual analysis to determine drivers of Mississippi River nitrogen and phosphorus loads from 1975 to 2017
This data release includes data processing scripts, data products, and associated metadata for a study investigating trends in Mississippi River nitrogen and phosphorus loads to the Gulf of Mexico. This data release consists of three main components: 1) Nitrogen and phosphorus balances and accumulation, which account for major nutrient inputs (fertilizer, manure, waste water treatment...
