Showing papers on "Sea-level curve published in 2008"
TL;DR: In this article, the authors constructed five palaeogeographic maps of the infill of the Lower Tagus Valley since ∼20,000-cal BP, showing that relative sea level rise and fluvial sediment supply were the prime forcing factors determining the depositional history and palaeographic changes.

TL;DR: In this paper, the densest network of echogrammes yet available for the Kieler Bucht, Western Baltic, the submarine erosional terraces have been mapped, and these correlate well with the features mapped and described by Kolp (1976) for the adjacent Mecklenburger Bucht.
Abstract: From analysis of the densest network of echogrammes yet available for the Kieler Bucht, Western Baltic, the submarine erosional terraces have been mapped. In general these correlate well with the features mapped and described by Kolp (1976) for the adjacent Mecklenburger Bucht. The lower terraces are at - 30 m and may reach 2100 m in broadness. Compared to present day conditions, the rates of cliff retreat at the time of formation were evidently much accelerated, due possibly to harsher climatic conditions including a greater intensity of winter lake ice, frosts, wind and rain. Other terraces at - 27, - 24, - 19, and - 14 m were identified, and these are related to syngressions in the various eustatic curves applicable to the Western baltic. A hypsometric curve for the submarine terrain of the Kieler Bucht, when compared to the relative sea level curve shows that 65% of the bay was transgressed in only 700 years. Maximum sedimentation rates in the Kieler Bucht should have occurred at this time, and independent data from dated cores from Vejsnas Rinne support this prediction.

TL;DR: In this article, the Chinese Ordovician acritarch diversity curve is presented using all literature data from South China(including the Yangtze Platform),Tarim and North China at the generic level.
Abstract: The Chinese Ordovician acritarch diversity curve is here presented using all literature data from South China(including the Yangtze Platform),Tarim and North China at the generic level.The diversity changes can partly be related to sea level changes,both at a regional(South Chinese sea level curve)and at a global level(global curve).The curve for all Chinese localities indicates that peaks in diversity apparently correspond to three sea level highstands at a global level at the early-middle Ordovician boundary(middle "Arenigian"),at the Sandbian-Katian boundary(middle "Caradocian")and during the Upper Katian(pre-Hirnantian "Ashgillian").
