Until recently the central highland of sub-Antarctic Marion Island was permanently covered with snow. Climatic amelioration has exposed the area, enabling the documentation of the geology and geomorphology. The lack of glacial and periglacial

Rock weathering as relative-age indicators are tested on rock surfaces of generally known chronological sequence on Marion island in the sub-Antarctic. While the weathering characteristics could not establish any chronosequence in the relict glacial

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.
Temperature as an environmental factor in the Arctowski Station Area (King George Island, South Shetlands Islands)

Data on the temperature of the air and bodies of water, as well as soil at depths 5-100 cm were collected in the vicinity of the Polish Arctowski Station on King George Island in the years 1979-1998. The temperature data for the soil surface layer
Prospects for climate change on three Polynesian outliers in Solomon Islands : exposure, sensitivity and adaptive capacity
Adaptation ; Climatic change ; Island ; Pacific Region ; Scenario ; Vulnerability
This paper discusses future prospects for climate change, impacts and adaptation of 3 small islands in Solomon Islands (Ontong Java, Bellona, Tikopia). Based on a review of literature a climate change scenario is suggested and with point
of departure in a survey of 3 characteristics of the islands ( bio-physical conditions, economic base and social organization). The exposure, sensitivity and adaptation options of island populations are analyzed. It is argued that the 3 islands are likely
factors, external to the islands, will be of increasing importance.
Advance of the outlet glaciers during regional warming as inferred from Late Holocene massive diamicton in the King George Island fjords, the South Shetland Islands, West Antarctica
Holocene sea-level changes and seismic crustal movements in a marginal coral reef area: the central and south Ryukyu Islands (Japan) in Proceedings. Volume 3. Symposia and seminars.
Investigations on marine notches, beachrocks and emerged intertidal barnacles have shown that the southern part of Okinawa Island was uplifted about 2.5 m approx. 2400 years ago, probably as a result of a great earthquake of an estimated magnitude
of 7.4 and a recurrence interval of 7000 to 10,000 years. Holocene crustal movements are discussed also in Ishigaki and Miyako islands.

Since the 1880s, the ice mass on the Tasman Glacier on SouthIsland has been shrinking. Beginning in the 1960s, lateral moraines and valley walls began to undergo slope failure of which the A. identifies four distinct types. Suggests a seasonal
Rock glaciers in the South Shetland Islands, Western Antarctica
This paper analyzes the results of an inventory of rock glaciers and protalus lobes in the South Shetland Islands. The work is based on aerial photo-interpretation, field recognition and measurements, and estimations of volumes, debris transport
This paper describes shore platforms around Shag Point on the eastern coast of SouthIsland, New Zealand. The interesting feature of these platforms is that within a very limited distance their elevation changes from supratidal to low tide level
