[1] This paper examines monthly variability of climatological mean sea surface temperature (SST) in the Black Sea. A total of eight products, including observationand model-based SST climatologies, are formed and compared with each other. Some of the observation-based SST data sets include only satellite measurements, while others combine in situ temperatures, such as those from moored and drif...

The instability and mobility of sand dunes is a major concern of planning and management in arid coastal plains. The aim of this study is to identify morphogenetic characteristics of sand masses and their locations, as well as to identify the processes that formed and transported them in the western part of the Makran coastal plain. Research data and tools were including spatial distributions o...

Dispersal of many coastal marine species is mediated by flows with strong directionality; bathymetric and topographic effects lead to strong alongshore variability in this transport. Using a simple model of the population dynamics of competing benthic species in a coastal ocean, we found that alongshore variability in dispersal can lead to clustering of species range boundaries for species whos...

The formation of Fe(III) oxyhydroxide colloids by oxidation of Fe(II) and their subsequent aggregation to larger particles were studied in laboratory experiments with natural water from a freshwater lake and a brackish coastal sea. Phosphate was incorporated in the solid phase during the course of hydrolysis of iron. The resulting precipitated amorphous Fe(III) oxyhydroxide phases were of varyi...

Global sea levels and the frequency severity of coastal storm events are both predicted to rise with anthropogenic climate change. Coastal storms often accompanied by intense wave energy producing large waves which lead impact damage, overtopping flooding infrastructure Erosion soft coasts can cause instability exacerbate flood risk weakening natural protective features like dunes. To plan effe...

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
