David Evans and the ‘Amoeba’ Lab at the University of Southampton (UK), researching (foraminifera) biomineralisation and climate change in Earth’s past
Perhaps most usefully, we also provide a data processing tool that can solve multiple trace element datasets to simultaneously reconstruct temperature and Omega/[CO32-], while fully propagating all sources of uncertainty. (VM28-122 B/Ca + Sr/Ca as an example)

Today in the Amoeba lab - an initial step on our path to building a new dedicated foraminifera culturing facility. Here are our first images of live foraminifera!
