Overfishing and other human pressures are severely harming many marine protected areas around the world, study finds
ecological destruction edge effect marine conservation areas MPA
<
2021/8/11
A new study points to a strong 'edge effect' in marine protected areas (MPAs), sharply reducing by 60 percent the fish population living up to 1 - 1.5 km within the MPA. This significantly diminishes ...
Climate regulation changed with the proliferation of marine animals and terrestrial plants
Climate regulation carbon-silicon cycle temperature
<
2021/8/3
Earth's climate was relatively stable for a long period of time. For three billion years, temperatures were mostly warm and carbon dioxide levels high - until a shift occurred about 400 million years ...
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...
MESMO 2: a mechanistic marine silica cycle and coupling to a simple terrestrial scheme

2014/12/12
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 respo...
Addressing the impact of environmental uncertainty in plankton model calibration with a dedicated software system: the Marine Model Optimization Testbed
environmental uncertainty plankton model calibration a dedicated software system the Marine Model Optimization Testbed
<
2014/12/11
A wide variety of different plankton system models have been coupled with ocean circulation models, with the aim of understanding and predicting aspects of environmental change. However, an ability to...

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 ...
iGen 0.1: the automated generation of a parameterisation of entrainment in marine stratocumulus
automated generation parameterisation entrainment in marine stratocumulus
<
2014/12/9
In a previous paper we described a new technique for automatically generating parameterisations using a program called iGen. iGen generates parameterisations by analysing the source code of a~high res...
