Influence of production variables and starting material on charcoal stable isotopic and molecular characteristics [PDF]
, 2008 We present a systematic study on the effect of starting species, gas composition, temperature, particle size and duration of heating upon the molecular and stable isotope composition of high density (mangrove) and low density (pine) wood.

Groundwater recharge mechanisms inferred from isoscapes in a complex tropical mountainous region
Geophysical Research Letters, 2016 Stable isotope variations and groundwater recharge mechanisms remain poorly understood across the tropics, particularly in Central America. Here stable isotopes (δ18O and δ2H) in groundwater, surface water, and rainfall are used to produce high ...

Nickel and osmium isotope and trace element geochemistry of organic-rich sedimentary rocks: The first investigation of Ni isotope systematics in marine sediments [PDF]
, 2012 Understanding the chemical composition of organic-rich marine sediments has the potential to: 1) allow evaluation of variations in ocean chemistry, enabling assessment of changes in global processes throughout geological time; and 2) provide an increased

Multi-isotope analysis and the reconstruction of prey species palaeomigrations and palaeoecology [PDF]
, 2010 This thesis explores the use of multi-element isotope analysis and intra-tooth sampling to reconstruct prey species ecology and biogeography. Modern caribou (Rangifer tarandus ssp.) and bison (Bison bison) from North America are used to assess the ...
