A nonlinear dynamical model for the plankton population in a fixed sea area under influence of asymmetric multiple factors, including atmospheric CO2 concentration, temperature, nutrient seawater light intensity, and predator density is proposed to address survival due global warming. The model’s accuracy confirmed by comparison with actual data, numerical simulations are carried out justify re...

The amount of fluvial input has important impacts on shelf regions. To understand how the magnitude discharge affects plume ecosystems, particularly organic carbon consumption, data over 10 consecutive summers (2003–2012) were examined in Changjiang River East China Sea. area ranged from approximately 4.90 × 103 km2 to 94.83 and varied proportion freshwater rate. Plankton community respiration ...

A review and discussion of analytical developments in the determination of DDTs and PCBs in sea environment are presented, including sample treatment, clean-up, identification and quantitative determination by gas-liquid chromatography. The fates of chlorinated hydrocarbons in the sea are discussed with regard to the pollutant-particle association with surfaces and their dynamics in a coastal m...

A long-standing problem in plankton ecology is sparseness of taxa-specific data. New optical imaging systems are becoming available which can acquire high-resolution data on the abundance and biomass of plankton taxa. The Video Plankton Recorder (VPR) has been designed and used for automatic sampling and visualization of major planktonic taxa at sea in real time, providing high-resolution data ...

The organic matter in the sea is unevenly distributed between the living plant and animal population, the suspended detritus, the organic matter in the sea bottom, and that present in the water in true and in colloidal solution. The living forms and the detritus make up only a small part of the total organic matter in the sea; the ratio between the organic matter in solution and that present in...

Climate change has had profound effects upon marine ecosystems, impacting across all trophic levels from plankton to apex predators. Determining the impacts of climate change on marine ecosystems requires understanding the direct effects on all trophic levels as well as indirect effects mediated by trophic coupling. The aim of this study was to investigate the effects of climate change on the p...

Despite recent evidence for sub-stock structuring, North Sea cod are assessed as a single unit. As a consequence, knowledge of sub-stock trends is poor. In particular, there are no recent evaluations of which spawning grounds are active. Here we report results from the first ichthyoplankton survey to cover the whole North Sea. Also, this survey, conducted in 2004, was the first to make extensiv...

The sea-surface microlayer (SML) forms the uppermost boundary layer between atmosphere and ocean, and has distinctive physico-chemical and biological features compared to the underlying water. First findings on metabolic contributions of microorganisms to gas exchange processes across the SML raised the need for new in situ technologies to explore plankton-oxygen turnover in this special habita...
