the rainy season 1995: a deep channel was eroded during two typhoons. In addition, the river started meandering. It is supposed that this reverse process will also occur in other channels, after the major sediment sources are depleted. The previously deposited sediments have been and will be re-eroded and transported farther downstream by hyperconcentrated flows and fluvial sediment transport. Due to new watershed areas the river channels will not necessarily adjust to pre-eruption conditions. Changes in the water and sediment regime affect almost all river channels for a distance of 50 to 100 km over the coming decades. Beside an unprecedented magnitude of the natural processes the socio-economic impacts are enormous: the eruption hit one of the most populous areas of the Philippines which serves as the granary for Luzon Island, including the capital area of Manila. To date about 350 square kilometres of agricultural land (mainly rice and sugar cane) are already covered by lahar sediments. A total of 1.5 million people are living within the endangered area. Nearly 70,000 families lost already their homes. The eruption itself and the ongoing lahar activity constitute a major impact to the economy of this Southeast Asian country. ZBIGNIEW ZWOLINSKI Mineral matter circulation within a polar geoecosystem, south Shetland Islands Quaternary Research Institute, Adam Mickiewicz University, Fredry 10,61-701 Poznan, Poland In the areas free from permanent glacier ice on the coast of King George Island (the South Shetlands), mineral material found in the Admiralty Bay geoecosystem comes primarily from volcanic rocks. Additionally, it is supplied by 418 glacial transport from ice cups, aerosol transport from the Admiralty Bay waters, littoral and aeolian transport (of various ranges), and meteoric fallout. These sources, however, are much less significant. Under the severe climatic conditions bedrocks undergo high-magnitude weathering, especially mechanical (disintegration, multigelation, exudation etc.). The big amounts of rock waste thus produced undergo denudation easily, and in effect are transported outside their area of provenance. Among the dominant denudation processes are mass movements, glacial erosion, abrasion, fluvial erosion, and deflation. Each of them involves its own type of waste transport: slope (including avalanches), glacial, littoral, fluvial, and aeolian. Of lesser significance are the periglacial and nival types of transport. In each of these morphogenetic environments deposition and redeposition takes place at various spatial and temporal scales. As a result of diverse transformation of the waste in morphogenetic and sedimentary environments, the Admiralty Bay drainage basin receives material of different origin, but mostly slope, glacial, fluvial, abrasion and aeolian. The material delivered to the Admiralty Bay assumes three forms: dissolved, suspended and solid. All three come as glacial and fluvial, partly also abrasion, material. Solid material derives exclusively from slope and aeolian processes. The supply of solids is determined by the occurrence of above-zero temperatures, and is only episodic unless produced by glacial and fluvial processes. The glacial and fluvial supply of dissolved and suspended material is continuous even in the short periods of sub-zero air temperatures. The supply of this type of material to the Admiralty Bay basin is decisive for the primary production of biomass. The waste reaching the Admiralty Bay can be transformed in only one or in. many morphogenetic environments with different hierarchical patterns. Besides land mineral matter, there are huge amounts of matter (mostly dissolved and suspended) reaching the Admiralty Bay from glacier fronts and Bransfield Strait in daily and seasonal cycles. Of no little significance is also meteoric fallout and aeolian fallout of a global range.
