Statistical sea surface temperature (SST) and chlorophyll a (Chl.a) maps and fields (monthly, seasonal and annual) have been prepared for the Black Sea region in the framework of the SeaDataNet project. Daily MODIS/Aqua (SST and Chl.a) and SeaWiFS (Chl.a) level 2 (L2) datasets were utilised to produce 1 km resolution final products, which are disseminated through the Internet. Data processing was done with the SeaDAS (SeaWiFS Data Analysis System) software package. Standard algorithms were used for calculation of Chl. a and SST. Only 'clean' pixels (i.e. pixels without any SeaDAS flag) were taken for averaging. Data interpolating empirical orthogonal functions (DINEOF) method was tested to reconstruct missing SST data, however, it did not work properly in conditions of insufficient data, producing some unrealistic results so it was not applied to the final products. In total, about 500 averaged maps and fields were prepared for period of September 1997 to December 2004 (Chl. a from SeaWiFS) and for period July, 2002, December 2007 (Chl. a and SST from MODIS).

Evaluation of glaciation and glacial shapes using geographic information systems and remote sensing (Eastern Black Sea)
Geçen, Reşat; Toprak, Vedat; Tombul, Saadettin; Department of Geodetic and Geographical Information Technologies (2011)
This study investigates the actual glaciers and the major properties of glacial landscapes (valleys, cirques and lakes) located over the Eastern Black Sea mountain chain using Geographic Information Systems (GIS) and Remote Sensing (RS) technologies. A database is created for each glacial feature that includes fundamental properties of each landscape. Data layers used in the study include digital and analog topographic maps, satellite images, geological maps and drainage maps. The studies carried out yielde...
Modeling the influence of hydrodynamic processes on anchovy distribution and connectivity in the black sea Karadeniz'deki hamsi dağılımı ve bölgeler arası bağlantısı üzerine hidrodinamik proseslerin etkisinin modellenmesi
Fach Salihoğlu, Bettina Andrea (2014-01-01)
Dispersal mechanisms of Black Sea anchovy larvae (Engraulis encrasicolus ponticus) across the Black Sea were studied with an individual based anchovy larvae model embedded in a Lagrangian model using surface currents calculated from daily dynamic height topography maps of altimeter data during a period of three years (2001-2003). Particles representing anchovy eggs were released at different sites during June to August and their movement was tracked over time. Drifters were advected for 36 days, representin...
Principal component and time series analysis of air-sea interactions in the "seas of the old world"
Gündüz, Murat; Özsoy, Emin; Graduate School of Marine Sciences (2002)
Climate data on surface atmospheric variables, sea surface temperature and computed air-sea fluxes are analysed to describe comparative surface climatolo gies of the 'Seas of the Old World' (Black, Caspian and Mediterranean Seas) and to investigate their interannual and interdecadal variability. Based on these analyses, differences and similarities between climates of these basins and their relationships to other global systems are identified. Empirical Orthogonal Function (EOF) Analysis is used to study sp...

The great success of the Tropical Rainfall Measuring Mission (TRMM) and its successor Global Precipitation Measurement (GPM) has accelerated the development of global high-resolution satellite-based precipitation products (SPP). However, the quantitative accuracy of SPPs has to be evaluated before using these datasets in water resource applications. This study evaluates the following GPM-era and TRMM-era SPPs based on two years (2014-2015) of reference daily precipitation data from rain gauge networks in te...
Comparison of regression and kriging techniques for mapping the average annual precipitation of Turkey
Bostan, P.A.; Heuvelink, G.B.M.; Akyürek, Sevda Zuhal (Elsevier BV, 2012-10)
Accurate mapping of the spatial distribution of annual precipitation is important for many applications in hydrology, climatology, agronomy, ecology and other environmental sciences. In this study, we compared five different statistical methods to predict spatially the average annual precipitation of Turkey using point observations of annual precipitation at meteorological stations and spatially exhaustive covariate data (i.e. elevation, aspect, surface roughness, distance to coast, land use and eco-region)...
