Surface manifestations of non-tidal internal waves in the north-eastern Black Sea as viewed by satellite sensors

In present paper the satellite remote sensing data (obtained by Envisat ASAR, Terra and Aqua MODIS, and NOAA AVHRR instruments) is used to study coastal dynamics of the north-eastern Black Sea. Surface manifestations of internal wave (IW) packets were registered in ASAR images of the sea surface. Possible factors leading to the generation of non-tidal IWs are determined on the basis of joint analysis of available satellite remote sensing data of the sea surface in microwave, visual and IR ranges complemented by contact measurements. A mechanism of IW generation is suggested. The coherence between occurrence of IW surface manifestations and location of the density pycnocline layer is established.
