Microplastics in Arctic ecosystem discovered
microplastics Arctic ecosystem mollusks Coral red algae
2021/8/6
Around the Svalbard archipelago in the Arctic Ocean, rhodoliths made up of coralline red algae provide ecological niches for a wide variety of organisms. A team of researchers has recently discovered ...
Global sensitivity analysis,probabilistic calibration,and predictive assessment for the data assimilation linked ecosystem carbon model
Global sensitivity analysis probabilistic calibration predictive assessment data assimilation linked ecosystem carbon model
2015/8/6
In this paper we propose a probabilistic framework for an uncertainty quantification (UQ) study of a carbon cycle model and focus on the comparison between steady-state and transient simulation setups...
Improving the dynamics of Northern Hemisphere high-latitude vegetation in the ORCHIDEE ecosystem model
Northern Hemisphere high-latitude vegetation ORCHIDEE ecosystem model
2015/8/6
Processes that describe the distribution of vegetation and ecosystem succession after disturbance are an important component of dynamic global vegetation models (DGVMs). The vegetation dynamics module...
Freeze/thaw processes in complex permafrost landscapes of northern Siberia simulated using the TEM ecosystem model: impact of thermokarst ponds and lakes
Freeze/thaw processes complex permafrost landscapes northern Siberia simulated TEM ecosystem model thermokarst ponds and lakes
2014/12/19
Freeze/thaw (F/T) processes can be quite different under the various land surface types found in the complex tundra of the Arctic, such as polygonal tundra (wet center and dry rims), ponds, and thermo...
Simulating high-latitude permafrost regions by the JSBACH terrestrial ecosystem model
High latitudes phenomenon freeze thaw coupling thermal stratified soil hydrological processes insulation moss cover basin northern system capture the dynamic
2014/12/18
The current version of JSBACH incorporates phenomena specific to high latitudes: freeze/thaw processes, coupling thermal and hydrological processes in a layered soil scheme, defining a multilayer snow...
Porting marine ecosystem model spin-up using transport matrices to GPUs
Porting marine ecosystem model spin-up transport matrices GPUs
2014/12/17
We have ported an implementation of the spin-up for marine ecosystem models based on transport matrices to graphics processing units (GPUs). The original implementation was designed for distributed-me...

The earth's climate system model the climate system biogeochemical cycle Marine geochemistry Ecosystems zooplankton
2014/12/10
Earth System Climate Models (ESCMs) are valuable tools that can be used to gain a better understanding of the climate system, global biogeochemical cycles and how anthropogenically-driven changes may ...
Seasonal leaf dynamics for tropical evergreen forests in a process-based global ecosystem model
Tropical evergreen forest canopy seasonal phenology photosynthesis ecosystem models canopy leaf photosynthetic capacity carbon dioxide the forest
2014/12/10
The influence of seasonal phenology on canopy photosynthesis in tropical evergreen forests remains poorly understood, and its representation in global ecosystem models is highly simplified, typically ...
Medusa-1.0: a new intermediate complexity plankton ecosystem model for the global domain
The sea is expected Plankton. Ecosystems The pump The carbon cycle. The terrestrial biosphere
2014/12/9
The ongoing, anthropogenically-driven changes to the global ocean are expected to have significant consequences for plankton ecosystems in the future. Because of the role that plankton play in the oce...
Terrestrial Ecosystem Carbon Fluxes Predicted from MODIS Satellite Data and Large-Scale Disturbance Modeling
Carbon Flux Deforestation MODIS Ecosystem Production
2013/3/8
The CASA (Carnegie-Ames-Stanford) ecosystem model based on satellite greenness observations has been used to estimate monthly carbon fluxes in terrestrial ecosystems from 2000 to 2009. The CASA model ...
Payment schemes for hydrological ecosystem services as a political instrument for the sustainable management of natural resources and poverty reduction – a case study from Belén, Nicaragua
Payment schemes hydrological ecosystem services a political instrument for the sustainable management of natural resources poverty reduction – a case study
2010/9/10
The importance of intact ecosystems for human-wellbeing as well as the dependence on functions and services they provide is undoubted. But still neither the costs of ecosystem degradation nor the bene...
Chemolithoautotrophic production mediating the cycling of the greenhouse gases N2O and CH4 in an upwelling ecosystem
Chemolithoautotrophic production the greenhouse gases N2O and CH4 an upwelling ecosystem
2010/1/21
The high availability of electron donors occurring in coastal upwelling ecosystems with marked oxyclines favours chemoautotrophy, in turn leading to high N2O and CH4 cycling associated with aerobic NH...
