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
MESMO 2 mechanistic marine silica cycle coupling simple terrestrial scheme
2014/12/16
Here we describe the second version of Minnesota Earth System Model for Ocean biogeochemistry (MESMO 2), an earth system model of intermediate complexity, which consists of a dynamical ocean, dynamic-...
How should sparse marine in situ measurements be compared to a continuous model: an example
sparse marine situ measurements be compared continuous model
2014/12/16
This work demonstrates an example of the importance of an adequate method to sub-sample model results when comparing with in situ measurements. A test of model skill was performed by employing a point...
Assimilating water column and satellite data for marine export production estimation
Assimilating water column satellite data marine export production estimation
2014/12/12
Recent advances in satellite retrieval methodology now allow for estimation of particular organic carbon (POC) concentration in ocean surface waters directly from satellite-based optical data. Because...
MEDUSA-2.0: an intermediate complexity biogeochemical model of the marine carbon cycle for climate change and ocean acidification studies
MEDUSA-2.0 intermediate complexity biogeochemical model marine carbon cycle climate change ocean acidification studies
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...

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 ...
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...
