By: A. Orfila; J. Tintoré; A. Jordi; G. Basterretxea

Description: IMEDEA (CSIC-UIB), Institut Mediterrani d’Estudis Avançats, Esporles, Illes Balears, Spain. In this paper, we present the results from a high horizontal resolution numerical simulation of the northwestern Mediterranean using a z-level, non-hydrostatic, primitive equation ocean model (DieCAST). The high resolution allows an accurate representation of the submarine canyons that presides in the region. The model is one-way coupled to a large scale model of...

Description: Centro de Investigación Científica y de Educación Superior de Ensenada (CICESE), Unidad La Paz, Miraflores No. 334, Fracc. Bella Vista, La Paz BCS, 23050, Mexico. The Gulf of Ulloa, a highly productive area off the western coast of Baja California Peninsula, is examined for five successive years (2003–2007) by using satellite data and seasonal net primary productivity estimates obtained by a vertical generalized production model. The results clearly ident...

By: N. Bin Abu Bakar; S. Jamshidi

Description: School of Physics, Universiti Sains Malaysia, 11800 USM, Penang, Malaysia. Phytoplankton as chlorophyll-containing organisms is the first step of production in most marine processes and food chains. Nutrient enhancement in the seawater due to the discharge of agricultural, industrial, and urban wastes threatens the Caspian Sea environment. Increasing concentrations of chlorophyll-a in seawater, in reaction to the elevation of nutrient supply can ...

Description: Fundación Centro de Estudios Ambientales del Mediterraneo, CEAM, Paterna, Valencia, Spain. Throughout Europe the summer of 2003 was exceptionally warm, especially July and August. The European Environment Agency (EEA) reported several ozone episodes, mainly in the first half of August. These episodes were exceptionally long-lasting, spatially extensive, and associated to high temperatures. In this paper, the 10$ndash;15 August 2003 ozone pollution event ...

By: B. Hünicke; E. Zorita; N. Tim

Description: Helmholtz-Zentrum Geesthacht, Institute of Coastal Research, Max-Planck-Strasse 1, 21502 Geesthacht, Germany. Detecting the atmospheric drivers of the Benguela upwelling systems is essential to understand its present variability and its past and future changes. We present a statistical analysis of a high-resolution (0.1°) ocean-only simulation driven by observed atmospheric fields over the last 60 years with the aim of identifying the large-scale atmosp...

Urban Warming in Villages : Volume 12, Issue 1 (13/07/2015)

By: J. Esper; C.S.B. Grimmond; J. Lindén

Description: Department of Geography, Johannes-Gutenberg University, Mainz, Germany. Long term meteorological records (> 100 years) from stations associated with villages are generally classified as rural and assumed to have no urban influence. Using networks installed in two European villages, the local and microclimatic variations around two of these rural-village sites are examined. An annual average temperature difference ($\Delta{T}$) of 0.6 and 0.4 K was obser...

By: S. C. Hackenberg; L. J. Carpenter; S. J. Andrews

Description: The University of York, York, YO10 5DD, UK. The oceans are a key source of a number of atmospherically important volatile gases. The accurate and robust determination of trace gases in seawater is a significant analytical challenge, requiring reproducible and ideally automated sample handling, a high efficiency of seawater–air transfer, removal of water vapour from the sample stream, and high sensitivity and selectivity of the analysis. H...

Description: Oceanography Centre, University of Cyprus, Nicosia, Cyprus. The MyOcean marine core service, implementing the Global Monitoring for Environment and Security (GMES) objectives, targets the provision of ocean state data from various platforms to assist, among other downscaled activities, the needs of the operational response to marine safety, particularly concerning oil spills. The MEDSLIK oil spill and trajectory prediction system makes use of the MyOcea...

By: D. Spivakovskaya; E. Deleersnijder; A. W. Heemink

Description: Department of Mathematical Physics, Delft Institute of Applied Mathematics (DIAM), Delft University of Technology, Mekelweg 4, 2628 CD Delft, The Netherlands. Random walk models are a powerful tool for the investigation of transport processes in turbulent flows. However, standard random walk methods are applicable only when the flow velocities and diffusivity are sufficiently smooth functions. In practice there are some regions where the rapid but contin...

Using Dissolved Oxygen Concentrations to Determine Mixed Layer Dep...

By: K. Castro-morales; J. Kaiser

Description: University of East Anglia, Norwich, UK. Concentrations of oxygen (O2) and other dissolved gases in the oceanic mixed layer are often used to calculate air-sea gas exchange fluxes; for example, in the context of net and gross biological production estimates. The mixed layer depth (zmix) may be defined using criteria based on temperature or density differences to a reference depth near the ocean surface. However, temperature c...

By: L. Bertino; E. Simon

Description: Nansen Environmental and Remote Sensing Center, Norway. We consider the application of the Ensemble Kalman Filter (EnKF) to a coupled ocean ecosystem model (HYCOM-NORWECOM). Such models, especially the ecosystem models, are characterized by strongly non-linear interactions active in ocean blooms and present important difficulties for the use of data assimilation methods based on linear statistical analysis. Besides the non-linearity of the model, one is...
