The AA. review some of the latest Quaternary paleoenvironmental changes in the Japan Sea, and discuss possible mechanisms linking sealevel change driven primarily by North Atlantic events and a Younger Dryas-type oscillation in the northwest
Notes on the holocene sea-level study in Japan. On the basis of Atlas of holocene sea-level records in Japan.
Summarizes the results of recent researches and some problems on the Holocene sea-level change in Japan. The studies are concentrated on the areas of large coastal plains. Uplifting areas fringed by the Holocene marine terraces (south Kanto, Rynkyn
islands have been also intesively studied. Most Japanse sea-level curves are characterized by higher sea-level of ca. 6000 y. B. P. which followed rapid sea-level rise accompanying the deglaciation. Subdivision of the terraces was probably caused by co
Sealevel change: environmental and socio-economic impacts
Economic impact ; Fishery;Fishing ; Global change ; Impact study ; Ocean ; Sealevel
Recent calculations that a rapid sealevel rise is imminent, has prompted concerned efforts at meeting the socio-economic impacts that are likely to occur. These impacts, rather than being localized and temporary as has been true in the recent past
This study demonstrates the utility of the whole-rock aminostratigraphy method for dating and correlating widespread emergent marine deposits. It constitutes the first regional geochronological framework for the Bahamas, and highlights major sea
Sequence stratigraphy, depositional history, and middle to late Quaternary sealevels of the Ventura shelf, California
California ; Marine quaternary ; Sealevel ; Seismic method ; Stratigraphy ; Tectonics ; United States
Through analysis of high resolution seismic-reflection profiles, this paper addresses the middle to late Quaternary history of sedimentation of the Ventura shelf and associated glacioeustatic sealevel fluctuations, and it constructs a chronology
Eustasy can no longer be defined as world wide simultaneous changes in sealevel, but must be redefined as ocean level changes or any absolute sealevel changes regardless of causation and including both the vertical and horizontal changes
of the geoid surface as well as changes of the dynamic sea surface topography. In the field, only relative sealevel changes can be observed (Author).
Analytical predictions of beach profile change in response to a sea-level rise in Geomorphology of changing coastlines.
Recent studies predict a sea-level rise of the order of 0.5 to 3.5 m by the year 2100. Beach profile translation and coastal erosion will, in most cases, accompany the rising level of the sea. Calculations for estimating potential erosion on a sandy
Forward and inverse models in sea-level studies in Models in geomorphology.
For regions in eastern North America it is the ice sheet that is the likely cause of incorrect predictions. Using a suitable inversion method a glacial history was found that efficiently fit the sea-level data.
Late Holocene sea-level changes seen from prehistoric settlements
Radiocarbon dates from prehistoric human settlements in Varanger, Finnmark, North Norway, are used to examine Holocene relative sea-level changes. (JH).
Raised coral terraces at Malakula, Vanuatu, southwest Pacific, indicate high sealevel during marine isotope stage 3

The occurence of a series of raised coral reefs from the uplifted island of Malakula (Vanuatu, SW Pacific) provide an opportunity to examine sea-level fluctuations over at least the past 120,000 years. Thirteen fossil coral samples from Malakula
were analysed by the thermal inonization mass spectrometry (TIMS) U/Th dating technique, yielding information on sealevels during late marine isotope stage 3 and early stage 4. The findings are in good agreement with sea-level estimates from raised
coral terraces in Papua New Guinea and the recent sea-level reconstruction from the deep-sea sedimentary δ O 18 records.
This work, based upon the results of 4 tide-gauges : Władysławowo, Hel, Gdynia and Gdansk-Harbour, presents the relative changes of sealevel and a determination of its quantitative and qualitative variability in the eastern part of the coast along
the Polish Baltic Sea. The first part of the paper examines long-term and seasonal fluctuations of sealevel, then the paper discusses the matter of amplitudes, and the final part analyses the appearance of high water levels and storm surges during the year.

The article deals with the issue of the sealevel rise as one of the indicators of climate change in Slovenian sea. The primary purpose of the article is to find out if the changing sealevel in Slovenian sea is a consequence of global climate
change in a period of forty-seven years. It is focused to investigate the reasons for the changes of mean sealevel and its influencing factors in north Adriatic Sea. Results on the analysis of time series of mean sealevel and factors are illustrated

The article deals with the relative sea-level, the isostasy, the sea-level fluctuations, the coastal mires, the macrofossils and the radiocarbon dating at Baltic Sea in North Eastern Germany. After a short geographic setting and data acquisition
the authors describe three case studies, the Körkwitz study site (mire Fischland located of the Saaler Bodden), the Augustenhof study site (small coastal mire located at the Großer Jasmunder Bodden) and the Wismar study site at the NE Germany Baltic Sea
Holocene sea-level rise recorded by a radiocarbon-dated mussel in a submerged speleothem beneath the Mediterranean Sea

Fossil shells of the boring mussel Lithophaga lithophaga provide a means for dating changes in relative sealevel. Here are reported data concerning the deepest submerged speleothem presently sampled in a temperate area, at 48 m below present sea
level off the west coast of Italy (Mediterranean Sea).

The A. summarizes the effects of climatic changes in the past, indicates the different types of man-induced climatic changes and discusses the (potential) effects of these changes on the worldwide average sea-level. Thereafter a summary
of the progress in geomorphological survey and mapping is presented with The Netherlands serving as an example. Finally some remarks are made on useful geomorphological data : survey and mapping can contribute in encountering the problems caused by sea-level rise
Global mean sealevel rise is a potentially sensitive indicator of climate change. Global warming will contribute to worldwide sea-level rise (SLR) from thermal expansion of ocean water, melting of montain glaciers and polar ice sheets
