Abstract
The spatiotemporal variability of chlorophyll concentrations on the North-Western Shelf of the Black Sea was studied. The monthly average chlorophyll data of the CMEMS for 2007-2017 are analyzed with a spatial resolution of 1 km. As a result, a breakdown scheme for 4 regions is proposed and the cross-correlation coefficients are estimated for each pair of neighboring regions by the moving correlation method. The wind field repeatability was analyzed using the six-hour ERA-Interim reanalysis surface wind data for the periods which were identified by the maximum values of the correlation coefficients. The duration and frequency of transport of chlorophyll between regions has significant interannual variability due to the variability of the wind field on the same time-scale. The results are discussed and compared with recent achievements about the spatial variability and cross-frontal exchange of chlorophyll on the North-Western Shelf of the Black Sea.
