Variability is one of the characteristic features of polar geoecosystems. On the meso- and macro-time scales, the variability of geoecosystems can be expressed in relation to : irregular interannual changes, multi-year cyclic changes, year-to-year
directional changes and anthropogenic changes. Polish multidisciplinary research concerning the physical, chemical and biological processes in the region of Admiralty Bay (King George Island, South Shetland Islands) demonstrates such variability.

Anthropogenic changes in the suspended load transportation by and sedimentation rates of the river Vistula, Poland
Evidence is presented that regulation works on the Vistula channel have introduced very significant and rapid changes in the magnitude of river load transportation and sedimentation. It is acknowledged that human interference represents the most
significant cause of change in the Vistula catchment within historical times. The alluviation of the Vistula valley floodplain as described here, which was initiated about 150 years ago, may be compared with the equally rapid changes of load transportation
