Abstract
A survey of recent bottom sediments in the Northern Aral Sea wasundertaken to elucidate the main direction of the alteration ofsedimentation processes as a result of the significant decrease in the levelof the sea from the beginning of the 1960s. Investigations were carried outin August–September 1991 from on board helicopter MI-8 MTV-1 which wasequipped with the navigation system "LORAN-OMEGA". Sediments were sampledby means of gravity coring and grab sampling. The frequency of sampling wasabout 1 station per 10 km2. At several sites, watersamples were collected. Grain-size analysis was undertaken and themineralogy of the sediments was determined by optical means, using an SEMenergy dispersive X-ray microanalysis, and X-ray diffractometry using aDRON-2.0 diffractometer.
