Abstract. Aprilia DA, Dianti, Arifiani KN, Cahyaningsih AP, Kusumaningrum L, Sarno, Rahim KAA, Setyawan AD. 2020. Review: Biogeochemical process in mangrove ecosystem. Intl J Bonorowo Wetlands 10: 126-141. The ecosystem, one of the unique and distinctive aquatic ecosystems, is located tidal areas coast coastal tropics subtropics. Mangrove ecosystems have many ecological, environmental, social b...

Dynamical systems are the paradigm for the representation of complex systems. The fixed encoding in a closed set of equations, however, contrasts with the openness of biogeochemical systems. Parameter identification is a major problem in biogeochemical systems and calibration of parameters converts models into ‘fitting machines’. Openness, self-modification, and historicity of biogeochemical sy...

Ecological mechanisms influence relationships among microbial communities, which in turn impact biogeochemistry. In particular, microbial communities are assembled by deterministic (e.g., selection) and stochastic (e.g., dispersal) processes, and the relative balance of these two process types is hypothesized to alter the influence of microbial communities over biogeochemical function. We used ...

Riverstrahler is a process-based model of nutrient transfer and biogeochemical functioning of large river systems (Billen et al., 1994; Garnier et al, 1995; Billen & Garnier, 2000) at the seasonal scale. Its essence lies in the coupling of an original representation of the drainage network, partly based on the streamorder classification of Strahler (1957), with a detailed model of biogeochemica...

The ocean holds a large reservoir of carbon dioxide (CO2), and mitigates climate change through uptake of anthropogenic CO2. Fluxes of CO2 between the atmosphere and surface ocean are regulated by a number of physical and biogeochemical processes, resulting in a spatiotemporally heterogeneous CO2 distribution. Determining the influence of each individual process is useful for interpreting marin...

The general focus of this work is to explore, better understand, model and predict the interactive dynamics and variability of sub-mesoscale and mesoscale features and processes in the Philippine Straits region and their impacts on local ecosystems through i. physical-biogeochemical-acoustical data assimilation of novel multidisciplinary observations, ii. adaptive, multi-scale physical and biog...

Hypoxia conditions are increasing throughout the world, influencing biogeochemical cycles of elements and marine life. Hypoxia results from complex interactions between physical and biogeochemical processes, which can not be understood by observations alone. Models are invaluable tools at studying system dynamics, generalizing discrete observations and predicting future states. They are also us...

The main purpose for developing biofuel is to reduce GHG (greenhouse gas) emissions, but the comprehensive environmental impact of such fuels is not clear. Life cycle analysis (LCA), as a complete comprehensive analysis method, has been widely used in bioenergy assessment studies. Great efforts have been directed toward establishing an efficient method for comprehensively estimating the greenho...
