Micropaleontology, a study of microscopic remains of protists, plants and animals, is extensively applied in paleoceanography and paleoclimatology, and has also provided us with knowledge of the evolution of the biosphere. In addition, recently micropaleontological tools have been introduced more-and-more in modern day pollution monitoring and environmental assessments. This session welcomes contributions from all fields of micropaleontology, including, among others, foraminifera, coccolithophores, dinoflagellates and pollen. Both modern day field studies, assessing the relationship between a microfossil group and environmental conditions, and paleoenvironmental reconstructions comprise the focus of this session. Moreover, we welcome studies related to taphonomic processes, and laboratory studies on refining the proxy value of a microfossil group, or their biological features.
