  Juniper Publishers -  Journal of Oceanography Abstract Ecological models have been signficantly improved during the last decades, leading to more realistic predictions of coastal water processes under different forcing. Even though benthic sediments play an important role in biogeochemical processes occurring in the water column, in the past, very few modelling studies have taken into account these contributions. Recent efforts are being put into the implementation of coupled models, including the biogeochemistry processes occurring at both the upper benthic layer and the water column. This step is important, as along with the river supply, benthic nutrient regeneration can contribute significantly to the phytoplankton growth and the primary production. During the validation process, due to the important number of parameters involving these models, the application of Sensitivity Analysis for selecting the most important model parameters is highly needed. The importance of th...

  Juniper Publishers -  Journal of Oceanography Abstract At present, the World experiencing a high level of pollution due to anthropogenic activity and increasing Carbon Dioxode (CO 2 ) level in the atmosphere, which resulted in the global climate change and global warming. The world population is increasing at the same time the technology has also developed. Various anthropogenic activities cause a major impact of rising temperature in the atmosphere. The researchers are focusing on the biological ways to reduce CO 2  in the atmosphere and suggested that marine microalgae is the most promising approach to capture the CO 2  in the atmosphere and microalgae have the potential to utilize CO 2  as a carbon source for growth. The microalgae biofixation process is the main concept of sequestration. This article discusses that CO 2  capture by microalgae is a most preferable method compared to employing other terrestrial plants for carbon capture. Keywords: ...

  Juniper Publishers -  Journal of Oceanography Abstract Nearshore marine climate at the Port of Bethioua, located on the west of Algeria, were studied using real-time field data and climatological offshore data obtained from the UK Met Office. Total waves, swells in the offshore are hind-casted separately and were validated using buoy measurements were supplied by UKMO at a nominal cost. Shallow water wave transformations are modelled using the Teluray wave-current model to calculate shoaling, depth refraction and current refraction taking bathymetry and tidal flows from the TELEMAC flow model as inputs. The results are of particular importance in the context of planning of port and safe anchorage and movement and anchoring of vessels in the harbour area, in addition, for future developmental programs at the port of Bethioua. Go to Introduction Waves are of varied forms, frequencies and directions. To arrive at their climatological picture has always been a challenge to harbo...
