Carbonate geochemistry, Professor Lohmann’s principal area of specialization in the geological sciences, utilizes the chemistry and fabric of carbonate minerals to reconstruct the conditions present in ancient environments. Studies undertaken in Professor Lohmann’s program have developed new analytical methodologies and interpretive approaches which have been applied to several areas of exciting research in the earth sciences. These include: evaluation of secular changes in ocean chemistry over the last billion years; reconstruction of latitudinal thermal gradients during times of global warming; and resolution of intra-annual temperature seasonality for continental settings.
