متن کاملGlobal vulnerability of peatlands to fire and carbon loss
11 Peatland ecosystems accumulate thick organic soil layers because plant production exceeds decomposition throughout the entire organic soil column (Fig. 1). Peatlands cover only about 2–3% of the Earth’s land surface but store around 25% of the world’s soil carbon1. They are most abundant at northern high latitudes (Fig. 2a), where they cover roughly 4,000,000 km2 of land1 and store an estima...
متن کاملBoundary conditions control for a Shallow-Water model
A variational data assimilation technique was used to estimate optimal discretization of interpolation operators and derivatives in the nodes adjacent to the rigid boundary. Assimilation of artificially generated observational data in the shallow-water model in a square box and assimilation of real observations in the model of the Black sea are discussed. It is shown in both experiments that co...
متن کاملMitigating wildfire carbon loss in managed northern peatlands through restoration
Northern peatlands can emit large amounts of carbon and harmful smoke pollution during a wildfire. Of particular concern are drained and mined peatlands, where management practices destabilize an array of ecohydrological feedbacks, moss traits and peat properties that moderate water and carbon losses in natural peatlands. Our results demonstrate that drained and mined peatlands in Canada and no...
متن کاملHeadwater Influences on Downstream Water Quality
We investigated the influence of riparian and whole watershed land use as a function of stream size on surface water chemistry and assessed regional variation in these relationships. Sixty-eight watersheds in four level III U.S. EPA ecoregions in eastern Kansas were selected as study sites. Riparian land cover and watershed land use were quantified for the entire watershed, and by Strahler orde...
