Description
1901-2099 estimates for export and leaching of dissolved inorganic carbon (DIC), dissolved organic carbon (DOC), total organic carbon (TOC), particulate organic carbon (POC), ammonium (NH4+), nitrate (NO3-), and total organic nitrogen (TON) from the Mississippi River Basin to the Gulf of Mexico. Data is generated by the Dynamic Land Ecosystem Model 2.0 (DLEM 2.0), covering a historical period and future projections under high and low socio-economic scenarios.
Use Cases
Analyzing long-term trends in dissolved inorganic carbon (DIC) and nitrate (NO3-) export to assess impacts on Gulf of Mexico hypoxia.
Modeling the effects of fertilizer application and land-use changes on total organic nitrogen (TON) and particulate organic carbon (POC) leaching.
Projecting future carbon export under different socio-economic scenarios using total organic carbon (TOC) and dissolved organic carbon (DOC) estimates.
Studying the combined influence of atmospheric CO2, nitrogen deposition, and climate variability on river basin biogeochemistry.
Strengths
Provides a 198-year temporal coverage from 1901 to 2099, combining historical reconstruction with future projections.
Models multiple nutrient species (carbon and nitrogen compounds) under two distinct socio-economic and climate scenarios.
Generated by a named process, the Dynamic Land Ecosystem Model 2.0 (DLEM 2.0), which integrates multiple environmental drivers.
Limitations
Specific column names, row counts, and file sizes are not provided by any source platform.
Future projections (2010-2099) are limited to carbon estimates only, not nitrogen species.
Conflicting 'last updated' metadata: one source shows 2099-12 31, another shows 2026-03-13.
