The Quaternary, the last 2.6 million years of geological time, saw major climatic changes which caused ice sheets to advance intotemperate latitudes. Repeated glacial episodes caused significant fluctuations in sea level, major geographical changes and major plant and animal population migrations. Sedimentary sequences record these changes in great detail and are central to unravelling past events.

Cambridge Quaternary is a semi-informal research group of approximately 60 people within the University of Cambridge . Its constituent research groups are based in the Departments of Geography , Plant Sciences , Earth Sciences , shadowsock如何使用 and Zoology . Links also exist with the Department of Physics and the Scott Polar Research Institute . There is an excellent research environment at all levels, fostered by the staff (10 members), post-doctoral workers, and both Ph.D. and M.Phil. students pursuing interdisciplinary research in a wide range of Quaternary fields. This environment is unique in Britain, offering opportunities for research student training unequalled elsewhere, in terms of the range and quality of the expertise available.

Department of Zoology, University of Cambridge.

Title: A comprehensive climate history of the last 800,000 years and its
application to ecological modelling

Understanding ecosystems and their evolution through the climate of the Pleistocene ice ages requires detailed palaeo-climate reconstructions. Global climate models (GCM) are frequently used to explore the many
diverse aspect of past climates.

However, due to their high computational demand a continuous and spatially detailed exploration of the past remains elusive. In this talk, I will present a GCM emulator, which is based on climate snapshot simulations of the last 120ka, that allows us to reconstruct the climate of the last 800,000 years (and beyond) in a quasi-continuous way.

I will show how the predictive skill of the GCM emulator can be tested against existing Pleistocene climate proxies and I will present a few highlights of how such an emulator can
be used for ecological modelling, for example, the dispersal of anatomically modern humans out of Africa.

After this one (Nov 1) , the next Cambridge Quaternary talk will be: Global Estimates of Marine Nitrogen Fixation based on a Non-Redfield Inverse Model

It has been announced that the proposals for the subdivision of the Holocene Series/Epoch (11 700 years ago to the present day) into three stages/ages and their corresponding subseries/subepochs by the International Subcommission on Quaternary Stratigraphy (ISQS) (a subcommission of the International Commission on Stratigraphy – ICS) have been ratified unanimously by the International Union of Geological Sciences (IUGS). The subdivisions now formally defined are: 1. Greenlandian Stage/Age = Lower/Early Holocene Subseries/Subepoch. Boundary Stratotype (GSSP): NorthGRIP2 ice core, Greenland (coincident with the Holocene Series/Epoch GSSP, ratified 2008). Age: 11,700 yr b2k (before AD 2000). 2. Northgrippian Stage/Age = Middle/Mid-Holocene Subseries/Subepoch. Boundary Stratotype (GSSP): NorthGRIP1 ice core, Greenland. Global Auxiliary Stratotype: Gruta do Padre Cave speleothem, Brazil. Age: 8326 yr b2k. 3. Meghalayan Stage/Age = Upper/Late Holocene Subseries/Subepoch. Boundary stratotype (GSSP): Mawmluh Cave speleothem, Meghalaya, India.

Harry's intrepid determination to pursue a detailed understanding of changes in ocean chemistry in relation to volcanism and climate led to his winning many awards, including the Goldschmidt award and Lyell and Urey medals, and to achieving very significant progress in the understanding of the behaviour of the oceans. His gentle manner and quiet resolve made him and excellent teacher and leader of an outstanding research group. He will be greatly missed as a scientist, a gentleman, and a friend. Tributes to Harry Elderfield.

shadowdersocksr安卓下载 book provides a look at the climatic history of the last 2.6 million years during the ice age, a time of extreme climatic fluctuations that have not yet ended. The book focuses on the changing state of these glaciers and the effects of associated climate changes on a wide variety of environments (including mountains, rivers, deserts, oceans and seas) and also plants and animals. For example, at times the Sahara was green and colonized by humans, and Lake Chad covered 350,000 km2 larger than the United Kingdom. What happened during the ice age can only be reconstructed from the traces that are left in the ground. The work of the geoscientist is similar to that of a detective who has to reconstruct the sequence of events from circumstantial evidence. The book is published on 27 November 2015.

Paul Crutzen, an atmospheric chemist began popularising the idea of the Anthropocene in 2001, citing evidence such as humanity's alterations of biodiversity and our changing of the climate through the release of carbon dioxide and other greenhouse gases. Scientists agree that evidence of these and other global changes will leave a lasting impression in the geological record. However, the Anthropocene is not recognised by the International Commission on Stratigraphy (ICS), the body which safeguards the geological time scale. Jan Zalasiewicz's efforts may change that—his ICS working group wishes to formalise the Anthropocene time division.

Other geologists argue that the Anthropocene may not be suitable for the geological timescale at all. One critic, Philip Gibbard, a member of the ICS working group, says the time in which we now live should be called the Late Holocene, because it is consistent with this most recent official Epoch. "For the Anthropocene to merit formal definition, a global signature distinct from that of the Holocene is required that is marked by novel biotic, sedimentary and geochemical change," Gibbard wrote in a paper published last year. (article by Billings, in Nautilus 2014).

QPG joins GSI3D as a Consortium Member

7.12.12 - GSI3D (Geological surveying and investigation in three dimensions) is a methodology and associated software tool for 3D geological modelling which enables quick and intuitive construction of 3D solid models of the subsurface for a wide range of applications. The methodology and software has been developed jointly by the British Geological Survey (BGS) and INSIGHT GmbH and is being applied by the BGS, where it is the modelling tool of choice.
