The procedures involved in model development may be set out as a ten-step process, beginning with defining the purpose of the model and ending with evaluation of the appropriateness and utility of the completed model. This process, recently outlined by Jakeman et al. [2006], is often iterative as model development is a continuous process that refines and improves the intended capacity of the mo...

Researchers in the discipline of biogeochemistry face an enormous challenge as they perform carbon cycle studies related to global climate change. These include quantifying energy and element flows through the earth system and coupling these flows to the dynamic climate system with the goal of devising models that can be used to predict how these flows might change in the future. In facing this...

Forest ecosystems play a critical role in the cycles of carbon and water from local to global scales. These cycles and their variability, in turn, play an important role in the non-trivial emergent and self-organizing interactions between forest ecosystems and their environment. Observational evidence, based on micrometeorological eddy covariance measurements, suggests that heterogeneity and di...

Mechanistic models have been developed to understand longterm landfill emissions and settlement (White et al., 2004; McDougall, 2007) . By finding emission/settlement controlling processes with these models, mechanistic boundary conditions can be applied in modeling to enhance predictions. In our research, we focus on finding the mechanistic biogeochemical reaction network that best describes b...

This paper summarizes the glider activities carried out in the last 5 years by the IMEDEA Department of Marine Technologies, Operational Oceanography and Sustainability (TMOOS). TMOOS has been operating gliders in the Western Mediterranean Sea since 2006 and has set-up electronic and maintenance laboratories in order to establish a key glider port in the area. Twenty-two glider missions have be...

The expression of genes of biogeochemical interest in calcifying and noncalcifying life stages of the coccolithophore Emiliania huxleyi was investigated. Transcripts potentially involved in calcification were tested through a light-dark cycle. These transcripts were more abundant in calcifying cells and were upregulated in the light. Their application as potential candidates for in situ biogeoc...

A mechanistic, biogeochemical succession model, FIRE-BGC, was used to investigate the role of fire on long-term landscape dynamics in northern Rocky Mountain coniferous forests of Glacier National Park, Montana, USA. FIRE-BGC is an individual-tree model-created by merging the gap-phase process-based model FIRESUM with the mechanistic ecosystem biogeochemical model FOREST-BGC-that has mixed spat...

1. Rice is an important agricultural production system with more than 80 million ha of irrigated rice paddies in annual production globally. As water resources become scarcer, the competition between urban development and agriculture for available water will intensify. Paddy rice cropland distribution and management intensity will need to evolve over the coming decades to accommodate increased ...
