Export and Leaching of Carbon and Nitrogen from Mississippi River Basin, 1901-2099

This dataset provides 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 (MRB) to the Gulf of Mexico. The estimates are provided for a historical period of 1901-2014, and a future period of 2010-2099 (carbon estimates only) under two scenarios of high and low levels of population growth, economy, and energy consumption, respectively. The estimates are from the Dynamic Land Ecosystem Model 2.0 (DLEM 2.0). These data are applicable to studying how changes in multiple environmental factors (e.g., fertilizer application, land-use changes, climate variability, atmospheric CO2, and N deposition) affect the dynamics of leaching and export to the Gulf of Mexico.

本数据集提供了密西西比河流域（MRB）至墨西哥湾的溶解无机碳（DIC）、溶解有机碳（DOC）、总有机碳（TOC）、颗粒有机碳（POC）、铵离子（NH4+）、硝酸盐（NO3-）和总有机氮（TON）的出口和淋溶估算。估算数据涵盖1901年至2014年的历史时期，以及2010年至2099年的未来时期（仅碳估算），分别对应高增长和低增长的人口、经济和能源消耗两种情景。估算结果源自动态陆地生态系统模型2.0（DLEM 2.0）。这些数据适用于研究多种环境因素（如肥料施用、土地利用变化、气候变率、大气CO2和氮沉降）如何影响向墨西哥湾的淋溶和出口动态。
