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...
WRFv3.2-SPAv2: development and validation of a coupled ecosystem–atmosphere model, scaling from surface fluxes of CO2 and energy to atmospheric profiles
development ecosystem–atmosphere model
2014/12/12
The Weather Research and Forecasting meteorological (WRF) model has been coupled to the
Soil–Plant–Atmosphere (SPA) terrestrial ecosystem model to produce WRF-SPA.
Can we model observed soil carbon changes from a dense inventory? A case study over England and Wales using three versions of the ORCHIDEE ecosystem model (AR5, AR5-PRIM and O-CN)
model observed soil carbon changes inventory
2014/12/12
A widespread decrease of the topsoil carbon content was observed over England and Wales during the period
1978–2003 in the National Soil Inventory (NSI), amounting
to a carbon loss of 4.44 Tg yrW...
A new marine ecosystem model for the University of Victoria Earth System Climate Model
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...
Widespread variability in overnight patterns of ecosystem respiration linked to gradients in dissolved organic matter, residence time, and productivity in a global set of lakes
The ecological system lakes

Widespread variability in overnight patterns of ecosystem respiration linked to gradients in dissolved organic matter, residence time, and productivity in a global set of lakes。
Identifying variable sea ice carbon contributions to the Arctic ecosystem: A case study using highly branched isoprenoid lipid biomarkers in Cumberland Sound ringed seals
Sea ice carbon The arctic ecosystem
2014/10/16
We analyzed liver samples from 322 ringed seals (Pusa hispida) collected from Cumberland Sound (southeast
Baffin Island) to test our ability to differentiate between carbon sources in near apex preda...
Against the tide: Recent diversity increase enhances resource use in a coastal ecosystem
Against the tide coastal ecosystem
2014/4/2
Biodiversity losses in marine, terrestrial, and freshwater ecosystems have raised concerns about the maintenance
of sustainable ecosystem functions and services (‘‘biodiversity crisis’’). A positive ...
The roles of productivity and ecosystem size in determining food chain length in tropical terrestrial ecosystems
ecosystem size food chain length food web structure islands
2015/11/13
Many different drivers, including productivity, ecosystem size, and disturbance,
have been considered to explain natural variation in the length of food chains. Much remains
unknown about the role o...
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 ...
3D geospatial modelling and visualization for marine environment: Study of the marine pelagic ecosystem of the south-eastern Beaufort Sea, Canadian Arctic
GIS Oceanography Visualization Spatial, Modelling Three-dimensional, Interpretation
2014/4/25
Geospatial modelling of the marine pelagic ecosystem is challenging due to its dynamic and volumetric nature. Consequently, conventional oceanographic spatial analysis of this environment is in a 2D e...
Emergence of diversity in a model ecosystem
Emergence of diversity model ecosystem Populations and Evolution
2012/4/28
The biological requirements for an ecosystem to develop and maintain species diversity are in general unknown. Here we consider a model ecosystem of sessile and mutually excluding organisms competing ...
