DINEOF (Data INterpolating Empirical Orthogonal Functions) is an EOF-based technique to reconstruct missing data in satellite images. Sea surface temperature (SST) hourly cloudy data collected by EUMETSAT organization, have been used in order to present a fully reconstructed set. DINEOF method is described with details at Alvera-Azcárate et al. (20...

The Cyprus Oceanography Center has been constantly searching for new ideas for developing and implementing innovative methods and new developments concerning the use of Information Systems in Oceanography, to suit both the Center’s monitoring and forecasting products. Within the frame of this scope two major online managing and visualizing data sys...

The risk from oil spill pollution in the Mediterranean is high due to the heavy traffic of merchant vessels for transporting oil and to the increasing coastal and offshore platforms related to the hydrocarbon exploration. This is especially true in the Levantine Basin following the recent widening of the Suez canal and the increase of the offshore...

Here we present the first results from a four year study (2012-2015) on the use of citizen science for recording the species and abundances of jellyfish which occur in the coastal waters of Cyprus. In the total duration of this study 60 reports and 11 species of jellyfish were reported from the waters of Cyprus, with Mnemiopsis leidyi and Cassiopea...

The impact of sea surface currents to the estimation and modeling of wave energy potential over an area of increased economic interest, the Eastern Mediterranean Sea, is investigated in this work. High-resolution atmospheric, wave, and circulation models, the latter downscaled from the regional Mediterranean Forecasting System (MFS) of the Copernic...

During the last decade, Rixen (2005) and Alvera-Azkarate (2010) presented the DINEOF (Data Interpolating Empirical Orthogonal Functions) method, a EOF-based technique to reconstruct missing data in satellite images. The application of DINEOF method, proved to provide relative success in various experimental trials (Wang and Liu, 2013; Nikolaidis et...

Using Data INterpolating Empirical Orthogonal Functions (DINEOF) Algorithm for filling the missing data of AVHHR satellite images.

ArcGIS® is a well known standard on Geographical Information Systems, used over the years for various remote sensing procedures. During the last decade, Rixen (2003) and Azcarate (2011) presented the DINEOF (Data Interpolating Empirical Orthogonal Functions) method, a EOF-based technique to reconstruct missing data in satellite images. The recent r...

In the frame of the E-Wave project, funded by the Cyprus Research Promotion Foundation, the wave energy – the energy that can be captured by sea waves – is being studied in the sea area of Levantine Basin in the Eastern Mediterranean. The approach adopted is based on the simulation of the sea state over the area of interest by numerical wave modeli...

The need for efficient and effective on line data management is greatly recognized today by the marine research community. The Cyprus Oceanography Center at the University of Cyprus, realizing this need, is continuously working in this area and has developed a variety of data management and visualization tools which are currently utilized for both...

The wave energy, that is the energy that can be captured by the sea waves, is an alternative form of renewable energy which has not been exploited so far as other forms of “clean” energy despite some critical advantages that it possess like the low variability that allows the easier adaptation to the general grid. The E-wave project, coordinated by...

In a rapidly evolving operational and research framework concerning the global energy resources, new frontiers have been set for the scientific community work-ing on environmental and renewable energy issues. In particular, new numerical techniques supporting the accurate estimation of renewable energy sources are highly emphasized. In this framewo...

The MyOcean marine core service, implementing the GMES objectives is composed among other regional forecasting centres by the Mediterranean, Black Sea and Baltic Sea ones. These centres, provide to the intermediate and to the Member States national marine services, as well to the end-users, forecasting products for sea currents, temperature, salini...

Knowledge of the hydrographic character of the Levantine Basin increased dramatically with the few seasonal Physical Oceanography of the Eastern Mediterranean (POEM) cruises in the SE Levantine Basin during the 1980s. They first depicted the existence of a multi-pole gyre, the Shikmona gyre. This gyre consisted of three eddies, with the Cyprus warm...
