Phosphorus session on EGU 2016- abstract submission deadline 13 Jan

EGU 2016Please be aware of our session at the forthcoming EGU General Assembly (17-22 April, Vienna, Austria). Abstracts can be submitted here 13 January!

“Interdisciplinary Session on the Global Phosphorus Cycle”

Phosphorus (P) is an essential element for life on Earth and is tightly cycled within the biosphere. Throughout geological history, P availability has regulated biological productivity with impacts on the global carbon cycle. Today, human action is significantly changing the natural cycling of P. Phosphate mining has depleted geological P reserves, while increased inputs of P to terrestrial ecosystems have enhanced fluxes of P to lakes and the oceans. On land, the soil system is a biogeochemical fulcrum, responding to the perturbed P cycle and ultimately determining the magnitude and timing of inorganic and organic P fluxes between terrestrial and aquatic ecosystems. In aquatic environments, P inputs determine the trophic state of the ecosystem, while burial in sediments returns P to the geological sink, eventually forming economically viable P deposits. Throughout the P cycle, redox conditions play a key role in transformations and mobility of P.

This interdisciplinary session invites contributions to the study of P from across the geosciences, and aims to foster links between researchers working on different aspects of the P cycle. We target a balanced session giving equal weight across the continuum of environments in the P cycle, from geological deposits, through soils and groundwater, lakes, rivers and estuaries, to oceans and marine sediments. We welcome studies of both past and present P cycling, with a focus on novel techniques and approaches.

Keynote: Ben Turner, Smithsonian Tropical Research Institute, Panama: “Soil phosphorus and the ecology of tropical forests”
