Biogeochemical Controls on Coastal Hypoxia

Annual Review of Marine Science, Journal Year: 2018, Volume and Issue: 11(1), P. 105 - 130

Published: June 11, 2018

Aquatic environments experiencing low-oxygen conditions have been described as hypoxic, suboxic, or anoxic zones; oxygen minimum and, in the popular media, misnomer “dead zones.” This review aims to elucidate important aspects underlying depletion diverse coastal systems and provides a synthesis of general relationships between hypoxia its controlling factors. After presenting generic overview first-order processes, we system-specific characteristics for selected estuaries where adjacent human settlements contribute high nutrient loads, river-dominated shelves that receive large inputs fresh water anthropogenic nutrients, upwelling regions supply nutrient-rich, waters generates zones without direct influence. We propose nondimensional number relates timescale residence time guide cross-system comparison. Our analysis reveals basic principles generation framework discussing future changes.

Bioelectrocatalysis is an interdisciplinary research field combining biocatalysis and electrocatalysis via the utilization of materials derived from biological systems as catalysts to catalyze redox reactions occurring at electrode. synergistically couples merits both electrocatalysis. The advantages include high activity, selectivity, wide substrate scope, mild reaction conditions. possible renewable electricity electron source energy conversion efficiency. These properties are integrated achieve selective biosensing, efficient conversion, production diverse products. This review seeks systematically comprehensively detail fundamentals, analyze existing problems, summarize development status applications, look toward future directions bioelectrocatalysis. First, structure, function, modification bioelectrocatalysts discussed. Second, essentials bioelectrocatalytic systems, including transfer mechanisms, electrode materials, medium, described. Third, application bioelectrocatalysis in fields biosensors, fuel cells, solar catalytic mechanism studies, bioelectrosyntheses high-value chemicals summarized.

MEDUSA-2.0: an intermediate complexity biogeochemical model of the marine carbon cycle for climate change and ocean acidification studies

Geoscientific model development, Journal Year: 2013, Volume and Issue: 6(5), P. 1767 - 1811

Published: Oct. 29, 2013

Abstract. MEDUSA-1.0 (Model of Ecosystem Dynamics, nutrient Utilisation, Sequestration and Acidification) was developed as an "intermediate complexity" plankton ecosystem model to study the biogeochemical response, especially that so-called "biological pump", anthropogenically driven change in World Ocean (Yool et al., 2011). The base currency this nitrogen from which fluxes organic carbon, including export deep ocean, were calculated by invoking fixed C:N ratios phytoplankton, zooplankton detritus. However, due anthropogenic activity, atmospheric concentration carbon dioxide (CO2) has significantly increased above its natural, inter-glacial background. As such, simulating predicting cycle ocean entirety, ventilation CO2 with atmosphere resulting impact acidification on marine ecosystems, requires both inorganic be afforded a more complete representation specification. Here, we introduce MEDUSA-2.0, expanded successor includes additional state variables for dissolved alkalinity, oxygen detritus (permitting variable exported matter), well simple benthic formulation extended parameterizations phytoplankton growth, calcification remineralisation. A full description functionality, is provided multi-decadal spin-up simulation (1860–2005) performed. performance evaluated using diverse range observational data, MEDUSA-2.0 assessed relative comparable models output Coupled Model Intercomparison Project (CMIP5).

Although most research has focused on eutrophication as cause this trend, many other global- regional-scale anthropogenic influences may also play a role.

Abstract. The European Regional Seas Ecosystem Model (ERSEM) is one of the most established ecosystem models for lower trophic levels marine food web in scientific literature. Since its original development early nineties it has evolved significantly from a coastal model North Sea to generic tool simulations shelf seas global ocean. current release contains all essential elements pelagic and benthic parts ecosystem, including microbial web, carbonate system, calcification.
