Sentences with phrase «ocean biogeochemistry»

So we expected that ocean acidification - driven changes in ocean biogeochemistry in the water column can also be reflected in the microlayer.

Professor Achterberg, who is based at the National Oceanography Centre, Southampton, says: «There is an urgent need to understand micronutrient, trace element and isotope cycles to advance our understanding of ocean biogeochemistry in the present day ocean and in the past.

Deposition of mineral dust plays an important role in the biogeochemical cycle of the oceans, by providing the nutrient iron, which affects ocean biogeochemistry with feedbacks to climate and dust production (Jickells et al., 2005; Section 7.3.4.4).

Hence, use of coastal typologies, which consider the elements above, has led to an improved capacity to represent and integrate ocean biogeochemistry and CO2 fluxes (Laruelle et al. 2010) and may help identify contrasting modes of pH and Ω regulation in coastal waters.

The working group on coupled biogeochemical cycling and controlling factors dealt with questions regarding the role of plankton diversity, how ocean biogeochemistry will respond to global changes on decadal to centennial time scales, the key biogeochemical links between the ocean, atmosphere, and climate, and the role of estuaries, shelves, and marginal seas in the capturing, transformation, and exchange of terrestrial and open - marine material.

Biotic and human vulnerability to projected changes in ocean biogeochemistry over the 21st century.

Last but not least, ocean biogeochemistry impacts CO2 uptake in this region as well.

This work gradually transitioned to more complex representations of climate and investigations of transient CO2 changes with models incorporating simplified ocean biogeochemistry (Sarmiento and Le Quere, 1996; Sarmiento et al., 1998) towards fully prognostic carbon system models (Dunne et al., 2013).

This is an important advance because nutrient uptake is a central property of ocean biogeochemistry, and in many regions controls carbon dioxide fixation, which ultimately can play a role in mitigating climate change.

Theme 3 is improving biogeochemical, sediment, and coupled ocean - climate models to better account for how ocean acidification will affect ocean biogeochemistry and ecosystems.

Maher, B.A. et al. (2010) Global connections between Aeolian dust, climate and ocean biogeochemistry at the present day and at the last glacial maximum.

«Oxygen minimum zones play key roles in ocean biogeochemistry and are an important repository of microbial animal biodiversity,» she said.

For example, Theme 3 exploits information from Theme 2 to help predict future changes in ocean biogeochemistry and ecosystems, but results from Theme 3 also feed back into Theme 2 by providing critical information on the expected temporal and spatial changes of ocean acidification and thus enable meaningful experimental designs.

A pH sensor is not part of the CTD; this variable is considered to be «ocean biogeochemistry» rather than «physical oceanography» which has historically taken the back seat.

The International Ocean Carbon Coordination Project (who acts as the GOOS Biogeochemistry Panel) coordinates this highly diverse set of activities and facilitates the development of globally acceptable strategies, methodologies, practices and standards which homogenize efforts of the research community and scientific advisory groups as well as integrate the ocean biogeochemistry observations with the multidisciplinary global ocean observing system.

Our efforts over the last decade have focused on component model development in ocean biogeochemistry (Dunne et al., 2005; 2013) and land ecosystems (Shevliakova, et al., 2009), and subsequently representing the coupled carbon - climate system through Earth System Modeling and the role of anthrogogenic carbon emissions in the earth system (Dunne et al., 2013).
