This paper deals with the determination of relative heights of the seal-level during the Eemian in The Netherlands and adjacent parts of the North Sea region. Dating was based on pollen analysis. Eight levels have been established, four of them determining the phase of rising 被引量: 80 年...

Analysis of organic sediments, including their diatom and pollen contents, was carried out in a swamp forest on the coastal plain of So Paulo State (southeastern Brazil). A palaeoenvironmental reconstruction was made regarding this region where communities of fisher–gatherers lived in prehistory, pr...

Comparison of terrestrial and marine records of changing climate of the last 500,000 years A broad correspondence between long pollen sequences and the deep-sea oxygen isotope record has been noted for some time, but there has been little effort ... PC Tzedakis,V Andrieu,JLD Beaulieu,... ...
The new chronology enabled us to redate the old pollen profile [van Zeist and Woldring, 1978a, b] and to establish an accurate timescale for the reconstructed lake level change. Carbon 14 dates show that the highest lake terrace corresponds to high lake level at around 19,000 years B.P...
In the absence of radiometric dating, pollen zones provide a chronological framework for the Eemian throughout Europe. The similarity of the Eemian Material and methods The Eemian site Peski (60°9′13″N, 29°17′25″E) is located in the Karelian Isthmus, Russia (Fig. 1), and has a ...
Public Clouds today provide a variety of services for data anal- ysis such as Amazon Elastic MapReduce and Google BigQuery. Each service comes with a pricing model and service level agree- ment (SLA). Today's pricing models and SLAs are described at the level of compute resources (instance-...
aIn the anther, four microsporangia (pollen sacs) are positioned in two pairs. The pollen sacs of each pair are adjacent to each other and share a common dehiscence zone (the stomium). Each pair is a structural unit of the anther, called a theca, and combined with a connective. The ...
