This paper descibes the characteristics of, and outlines the most likely origins for, three forms of unusual patterned ground observed in the Falkland Islands, South Atlantic. The features here described are not products of frost-related processes
Geomorphology of South Atlantic Volcanic Islands. Part I: the Tristan da Cunha group
Volcanoes of the Tristan Group have varied physiography resulting from the interplay of repeated volcanic eruptions, coastal erosion and fluvial erosion. The geomorphic histories of the islands are more complicated than was described in earlier
Plate boundary tectonics and oceanic island geomorphology in The geomorphology of plate boundaries and active continental margins.
This paper illustrates how studies of the geomorphology of oceanic islands can contribute to the understanding of nearby plate boundaries. For this purpose, an oceanic island is defined as one within an ocean basin. Case studies are given of three
contrasting situations : a) islands behind a subduction zone (the Law islands behind the Tonga trench in the Pacific| b) an island oceanwards of a trench (Christmas island near the Sunda trench in the Indian Ocean| c) islands scattered each side of a spreading

For an investigation of the relation between the morphology and the tectonics in the Macaronesian Islands (i.e. the geographical group of middle AtlanticIslands between 10°N and 40°N, orientations studies have been made of steeply dipping joints
and, where possible, of the trends of valleys and ridges. A coincidence of the preferred directions of these features indicates a probable genetic relation between them. The main result is that the morphology of all Macaronesian Islands, although surficially
A review of amino acid racemization studies in Quaternary mollusks: stratigraphic and chronologic applications in coastal and interglacial sites, Pacific and Atlantic coasts, United States, United Kingdom, Baffin Island, and Tropical islands
Amino acid racemization (AAR) studies of Quaternary mollusks (mostly marine mollusks from coastal deposits) are reviewed. Data obtained in regional studies from the US Atlantic and Pacific coasts, Baffin Island, the United Kingdom, and tropical
islands are discussed as they relate to method evaluation, kinetic model development, and aminostratigraphic applications.

The main focus lies with climatic and hydrologic implications of the major circulation patterns in the northern North Atlantic, namely the North Atlantic Oscillation (NAO) and Arctic Oscillation (AO). The studies reviewed here reveal key
relationships between circulation, climate and streamflow across the northern North Atlantic, allowing the construction of a simple conceptual model for this system. To help promote a better understanding of the system, several research gaps are identified

of the North Atlantic Oscillation (NAO) index (extreme positive to extreme negative) and by extreme changes in annual sea ice extent across the Greenland Sea. It is suggested that this unusual relationship may be explained through the important role of sea ice
extent across the Greenland Sea affecting the extent of the polar anticyclone and hence the position of the North Atlantic storm track. By contrast, the later part of this time interval (AD 1894-1905) was characterized by very few winter gales
