Huybers' Identification of Deglaciations,
Cameron Thieme, School of Mathematics 


Huybers introduced a computer algorithm to automatically pick out deglaciations from paleoclimate data. There are problems with using the algorithm on alternate data sets and on data sets from different geologic times.
