The carbon budget of the North Sea

Effects of seawater pH on survival, growth, energy budget and oxidative stress parameters of juvenile turbot Scophthalmus maximus

This study aimed to elucidate the influence of environment pH on survival, growth, energy allocation and oxidative damage of juvenile Scophthalmus maximus (19.89±0.25 g). Six pH treatments (6.3±0.2、6.8±0.2、7.3±0.2、7.8±0.2、8.3±0.2、8.8±0.2) lasting for eight weeks were included. Measurements of survival (SR), feed conversion ratio (FCR), specific growth rate (SGR), weight gain rate (WGR), energy ...

Nitrogen and carbon cycling in the North Sea and exchange with the North Atlantic—A model study. Part I. Nitrogen budget and fluxes

The three-dimensional biogeochemical model ECOHAM was applied to the Northwest European Shelf (471410–631530N, 15150W–131550E) for the years 1993–1996. Nitrogen budgets were calculated for the years 1995 and 1996 for the inner shelf region, the North Sea (511,725 km). Simulated temperatures as well as nitrate, oxygen, and chlorophyll concentrations are compared with observations. The mid-1990s ...

CHAPTER 15. The First State of the Carbon Cycle Report (SOCCR): The North American Carbon Budget and Implications for the Global Carbon Cycle

The combustion of fossil fuels has increased carbon dioxide in the atmosphere, and the oceans have annually absorbed an equivalent of 20-30% of the carbon dioxide in fossil-fuel emissions. The present annual uptake by the oceans of approximately 1.8 billion tons of carbon (26% of global fossil-fuel emissions in 2003) is well constrained, has slightly acidified the oceans and may ultimately affe...

Preparation of Ceramic Composite Filter with Titanium Oxide Nanoparticles and Active Carbon Content for Treatment of Sea Water

In this mentioned study for sea water treatment ceramic composites were made from natural alumina and adsorbent active ingredients. According to the experimental results, filters along with active agents have acceptable effects on drinking water parameters and contaminants in compare with 1053 ISIRI standard. Modular set up was made for sea water treatment tests. Water flowrate after filtration...
