  Juniper Publishers -  Journal of Oceanography Abstract Most recently signed economic, political, and social agreements such as the Paris Agreement, the 2030 Agenda for Sustainable Development, or the FAO’s Blue Growth Initiative have as common objective the strengthening of the global response to the threat of climate change holding the increase in the global average temperature well below 2 °C above pre-industrial levels. Aside of the implementation of ambitious plans on adaptation and mitigation, our ability to contain climate change within safe limits depends largely on the evolution of the ocean circulation and state. The increased awareness of the rapid degradation of the ocean and its importance to the future of humanity is the result of decades of ocean research that has finally been embodied by the proclamation of a Decade of Ocean Science for Sustainable Development (2021–2030) by the United Nations General Assembly. In the framework of this program, there is an ext...

  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 Recent report of  Hydrocharis morsus-ranae  from Kasmir Himalaya-India should serve as an early warning to the whole South Asia that this invasive species might be already in the phase of breaking down of the historical biogeographic barrier (Himalayas) and may be introduced in the adjoining areas of South-East Asia in the near future. Therefore, it is high time to initiate early detection and rapid response, the most cost- effective strategy with maximum chances of success in the management of plant invasions. Keywords:  Early warning; South Asia; Invasion; Biogeographic barrier Go to Introduction The genus  Hydrocharis L.  is widely distributed in tropical and temperate regions of the old world (Cook and Luond, 1982), and comprises of 3 species namely:  H. dubia  (Blume) Backer,  H. morsus- ranae  L. and  H. chevalieri  (De Wildeman) Dandy. Biogeographically, these...

  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...
