Web Links

  • Fractionation Factors
    An online calculator for equilibrium fractionations of stable isotopes in a wide variety of (mainly condensed) phases.
  • GNIP
    Access the database of the Global Network of Isotopes in Precipitation program.
  • Hydrogen Isotope Standards
    Organic compounds for use as carbon- and hydrogen-isotopic standards in compound-specific isotope analyses, from my colleague Arndt Schimmelmann.
  • ISIS Draw
    A free chemical drawing program that I like a lot (except that no MacOS app is available).
  • Isogeochem
    A listserver and website for all things related to stable isotopes in geochemistry.
  • Isotopes in Precipitation
    Calculate isotopic composition of precipitation over time intervals.
  • Lipid Analysis
    The web site of W. Christie, author of the "Lipid Analysis" bible. Lots of information about analytical methods, including a library of mass spectra.
  • McLane Research
    The manufacturer of submersible, in-situ pumps for filtering seawater at depth. We love 'em.
  • Paleomap
    Paleogeographic maps showing the configuration of the continents through geologic history.
  • The Prokaryotes
    An encyclopedic collection of microbiological information about all of the major Prokaryotic groups.
