Land-Ocean Matter Flux

We work basically on three aspects:

1) Global scale matter fluxes

Pairing global spatial data with regional hydrochemical data (GLORICH), we develop a new global weathering model framework to quantify spatially explicit weathering related fluxes, as well as land-ocean carbon and nutrient fluxes.

2) The fate of carbon and nutrients in aquatic systems

The capacities of the hydrochemical laboratory and of cooperation partners help us to understand the fate of carbon and nutrients in the land-ocean-aquatic continuum.

3) Feedbacks of land-ocean matter fluxes

We parameterize a land-ocean-matter flux modules of coarser resolution for Earth System Models, recognizing inorganic and organic carbon, silica and liberation of phosphorus to ecosystems.

Currently we focus on two projects:

a) Providing Land-Ocean-flux estimations for coastal biogeochemical modelling within the Cluster of Excellence CLICCS A5 The Land–Ocean Transition Zone

b) Chemical weathering in active volcanic areas with focus on the Aso-Caldera and Kirishima (Partner Hosono Takahiro)
