The Quaternary Times New Web Sites
Bill Johnson has prepared a home page for the GSA Archaeological Geology Division. It is still a work-in progress, with sections yet needing work, such as the "photo gallery." Your suggestions would be appreciated: wcj@ukans.edu
NOAA’s Paleoclimatology Program produced this webpage to educate, inform, and highlight the importance of paleoclimate research; as well as to show how paleoclimate research relates to global warming and other important issues regarding climate variability and change.
This website details the Interior Department sponsored report on the ~8000-9000 year old Kennewick human remains. The report information on the skeletal biology of the remains, their geological context, and the legal issues they raise in regard to the Native American Graves Protection and Repatriation Act (NAGPRA). Other Kennewick related materials can be accessed through the Kennewick Man Virtual Interpretive Center, sponsored by the Tri-City Herald, at: http://www.tri-cityherald.com/bones/
The University of Arizona and Pierre Zippi have made all 2093 of the data files of the Deep Sea Drilling Program at this site. They can be downloaded individually as .txt files, or the entire dataset is available from NOAA on CD-ROM
This site houses the main CARD database, with over 6000 dates of archaeological and vertebrate palaeontological sites. In addition, "Mapping Ancient History", an interactive map based on the CARD dates that visually represents the location and spread of dated sites is located at: http:// wwwims1.gsc.nrcan.gc.ca/projects/mabasyquad/radiocarbon/indexC14.htm
Radiocarbon’s list of online 14C databases.
The classic article by M. Stuiver and H.A. Polach, "Discussion: Reporting of 14C Data" is now available in PDF (Adobe Acrobat) format on the Radiocarbon web server. This article, published in Radiocarbon in 1977, systematized the conventions used for calculating and reporting radiocarbon ages and isotopic fractionation. We are planning to publish an article revisiting radiocarbon terminology in a future issue (aka "Stuiver and Polach 2"). In the meantime, feel free to consult and/or print the original (one copy for personal use only, please.) David Sewell
Global Database of Borehole Temperatures and Climate Reconstructions http://www.geo.lsa.umich.edu/~climate/index.html The thermal regime of the Earth’s outer continental crust comprises the superposition of two conductive processes: the steady-state outward flow of heat from the deeper interior, and transient perturbations to the deep regime by changes of temperature at the surface. The latter effects are commonly climatological in origin. The identification of the transient component of the subsurface thermal regime is central to the geothermal approach to climate reconstruction, and has drawn increasing attention over the past decade. With support from the international hear flow community and under the sponsorships of the NSF and NOAA, a database of borehole temperatures has been assembled and analyzed for the special purpose of climate reconstruction (Huang and Pollack, 1998). This database currently contains 616 borehole temperature profiles from around the world. A set of overheads showing some key recent results of paleoenvironmental science can be downloaded from the PAGES website.
DIRTMAP Database Dust Indicators and Records of Terrestrial and Marine Paleoenvironments (DIRTMAP) has established a new public database. Mineral dust aerosols play an important role in the global climate system, by mediating physical and biogeochemical exchanges among the atmosphere, land and ocean. Atmospheric dust can have a profound effect on the earth system by affecting the radiative forcing of the atmosphere, through chemical reactions with other atmospheric constituents, and through its impact as a source of micronutrients to marine and terrestrial ecosystems. Climate modeling studies are underway to assess the effect of dust on the current climate. The DIRTMAP database will serve both the earth science and modeling communities. We are enlisting the help of the international community to produce this new database. For the first phase, we have established an interactive web form, through which members of the loess community can contribute information about their field sites to a global inventory. For the second phase, the database will target data from 0 to 30,000 yr BP, containing sediment age models and accumulation rates, bulk densities, mineralogical and provenance tracer data, grain size information, and chronological data. Scientists interested in contributing to this effort or in obtaining more information can contact Karen Kohfeld, the DIRTMAP Database coordinator at: Max Planch Institute for Biogeochemistry, Jena, Germany; dirtmap@bgc-jena.mpg.de Land Use History of the Colorado Plateau The CP-LUHNA website was introduced in late October to researchers, land managers and policy-makers at Northern Arizona University at the Fifth Biennial Conference of Research on the Colorado Plateau. The goal of this web site is to provide land managers and policy-makers with an accessible and comprehensive informational resource that describes the processes that drive long-term, broad scale ecological trends on the Plateau. Comments and new contributions are welcome. Contact: John Grahame; luhna@nau.edu. Permafrost Site Terrain Sciences Division of the Geological Survey of Canada has added a section on permafrost to its website. |
