Mass Spectrographs and the Birth of Stable Isotope Geochemistry
Originally published January 7, 2016 on paleopix.com/blog by Penny Higgins: I've been working on a little project that has required me to dig a little into the history of stable isotope geochemistry. Today I learned about the first mass spectrometers. I've found the results interesting and thought I might share them here. This is research … Continue reading Mass Spectrographs and the Birth of Stable Isotope Geochemistry
From the Archives – Lake Effect Snow – An Isotopic Study: Some Results
Originally published February 13, 2013 on paleopix.com/blog by Penny Higgins: A while ago, I proposed an experiment in which I collected snow at regular intervals during a Lake Effect Snow event. I made some predictions and collected the snow, and have now finally succeeded in analyzing the waters. The results weren’t quite what I expected. … Continue reading From the Archives – Lake Effect Snow – An Isotopic Study: Some Results
From the Archives – An Isotopic Study of Lake Effect Snow
First published January 19, 2013 at paleopix.com/blog by Penny Higgins: I’ve written a few blog posts about what can be done with isotopes from precipitation, and how that might assist us in understanding how to interpret isotopic data collected from ancient rocks and fossils. (Look here and here.) As I live here in western New … Continue reading From the Archives – An Isotopic Study of Lake Effect Snow
