Southern Exposure: New Paleoclimate Insights From Southern Ocean and Antarctic Margin Sediments
Southern Ocean Antarctic Margin Sediments
2015/7/15
Much of what is known about the evolution of Antarctica's cryosphere in the geologic past is derived from ice-distal deep-sea sedimentary records. Recent advances in drilling technology and climate pr...
Rare earth elements in the ornithogenic sediments from the Maritime Antarctic: A potential new palaeoecology proxy
Antarctica ornithogenic sediments rare earth elements
2017/4/12
The ornithogenic sediments in the maritime Antarctic are good archives for studying the changes of historical penguin
population. Rare earth elements (REEs) along with biological and lithophile eleme...
New approaches for automated data processing of annually laminated sediments
automated data processing annually laminated sediments
2009/11/11
Laminated sediments, like evaporites and biogenic lake sediments, provide high-resolution paleo-climate records. Yet detection and counting of laminae causes still problems because sedimentary structu...
New correlations of Telychian (Silurian) bentonites in Estonia
bentonite K-bentonite Telychian sanidine correlation
2009/10/22
Seventy-seven Telychian bentonite samples from six drill-core sections were correlated on the basis of their sanidine composition. In total, bentonites from 43 volcanic eruptions, of which six are new...
Focusing of phytodetritus deposition beneath a deep-ocean front, Chatham Rise, New Zealand
Focusing of phytodetritus deposition beneath deep-ocean front Chatham Rise New Zealand
2014/4/22
In October 2001, we observed a deep-ocean phytodetritus deposition event on Chatham Rise beneath the Subtropical Front (STF). The origin of this phytodetritus was probably an extensive phytoplankton b...
