Late Quaternary sea-level and tectonic changes in northeast Fiji
The islands of northeast Fiji studied are all the emergent parts of the northern end of the Lau^Colville Ridge, a remnant island arc which has been rising for most of the Quaternary. Within the study area, investigations of coastal landforms (primarily emerged notches and shore platforms) and emerged coral reefs allow rates of tectonic movements to be calculated. The Vanuabalavu Island group is...
متن کاملQuaternary coastal morphology and sea-level changes—an introduction
Few things remain static in natural systems and perhaps no better illustrated than by changes in the level of the ocean surface with respect to the land over Quaternary timescales. The position of sea level (ultimate base level) and changes of sea level over geological timescales represent important controls in the evolution of coastal environments, and as an agent of profound geomorphological ...
متن کاملMonitoring of environmental changes of Tabriz plain at Quaternary sediments
Abstract Sediments provide a continuous, sensitive record of changing conditions of environment and processes within plain and in the surrounding plain, thus they contain significant archives of past environmental change on the continents. Valuable informations on regional and global scale patterns of past climate variability in the Azarbayjan region have been documented by numerous paleocli...
متن کاملQuaternary tracking of the Basin changes (Case Study: Ghezel Ozan)
The Ghezel Ozan basin in an area of 50000 KM2 is in the northwest of Iran. Recognition of variables like captivity and deviation of rivers, erosion and compact surfaces, the affects of old lakes by the reflected affects on 1:50000 scaled topographic maps of the region, are some of the points which is tried to find out the changes of Quaternary of the basin. Although Ghezel Ozan basin is ended t...
متن کاملSea level changes forced by Southern Ocean winds
[1] On regional scales, changes in sea level are significantly affected by local dynamical changes. Westerly winds over the Southern Ocean have been strengthening and shifting southward in recent decades, and this change is projected to continue in the future. This study applies wind forcing anomalies to an eddy-permitting ocean model to study the dynamical response to a Southern Hemisphere wes...
