Paleoclimatologists study ice cores to investigate earth’s past climate. they use methods such as oxygen isotope analysis. which feature inside the ice are the scientists interested in analyzing and why? they search for the geological layer at which ice turns to water, which is an indicator of past precipitation data. they seek single-celled microorganisms deep within the ice to assess the efficiency with which they processed oxygen. they study air bubbles trapped in the ice, comparing their chemical composition between past and present. they build a temperature and albedo profile of ice and water samples to predict when and where climate change is eminent.
