Project Title:Impacts of Changing Climate and Land Use on Carbon Cycling and Budgets of the Coastal Ocean Margin: Observations, Analysis, and Modeling

Project Leader(s):

Marjorie (Marjy) Friedrichs, Virginia Institute of Marine Science
Eileen Hofmann, Old Dominion University

Project Duration: 2011 - 2015
Solicitation:NASA: Interdisciplinary Research in Earth Science (2009)
Abstract: The overall goal of this project is to investigate the impact of climate variability, climate change, and land-cover/land-use change on the transport and cycling of carbon and nitrogen to and within the coastal ocean margins. This goal will be achieved by linking an ocean biogeochemical-circulation model of the Northeastern North American continental shelf (NENA) to a Dynamic Land Ecosystem Model (DLEM). Both models will be initialized, forced and evaluated with a large suite of satellite data products. Three interconnected research questions will be addressed: 1) how do extreme climate events (floods, droughts) and climate change (temperature, precipitation, solar radiation) affect the magnitude and seasonality of river discharge, and transports of carbon and nitrogen from upland landscapes to the continental margin; 2) what are the impacts of these changes in terrestrial runoff on ecosystem processes and biogeochemical cycling within the continental margin and o n cross-shelf nutrient and carbon fluxes; and 3) how will projected land use, climate variability, and climate change influence carbon and nitrogen cycling in the US eastern coastal ocean margins through changing the structure and function of terrestrial ecosystems in major watersheds on time scales of a century from now? These research questions will be addressed with an integrated modeling and data analysis approach. Much of the development and evaluation of the terrestrial (DLEM) and coastal ocean (NENA) models has been accomplished through prior activities, and thus the emphasis now is to couple the models and initiate coupled land-ocean simulations to address our interdisciplinary research questions.

Product Title:  CMS: Annual Estimates of Global Riverine Nitrous Oxide Emissions, 1900-2016
Start Date:  01/1900      End Date:  12/2016     (1900-2016)
Description:  This dataset provides modeled estimates of annual nitrous oxide (N2O) emissions at a coarse geographic scale (0.5 x 0.5 degree) for two sets of global rivers and streams covering the period of 1900-2016. Emissions (g N2O-N/yr) are provided for higher-order rivers and streams (4th order). The estimates were derived from a water transport model, the Model for Scale Adaptive River Transport (MOSART), coupled with the Dynamic Land Ecosystem Model (DLEM) to link hydrology and ecosystem processes pertaining to N2O flux and transport. Factors driving the model included climate, land use and land cover, and nitrogen inputs (i.e., fertilizer, deposition, manure, and sewage). Nitrogen discharges from streams and rivers to the ocean were calibrated from observations from 50 river basins across the globe.
