The unique and frequently beautiful morphologies that characterize many biominerals have
long been a source of fascination. While research began by looking first at individual …

Diatom silica (frustules) are a form of biogenic opal and contain oxygen isotopes that are
being increasingly used in palaeoclimate studies. Frustules are comprised of an inner …

Understanding the timing and character of the expansion of Homo sapiens out of Africa is
critical for inferring the colonization and admixture processes that underpin global …

The nature of human dispersals out of Africa has remained elusive because of the poor
resolution of paleoecological data in direct association with remains of the earliest non …

Water level changes result from a variety of geological, biological or climatic processes.
Many of these changes occur over long periods of time; however, some may be rapid or …

Diatom dissolution in surface sediment samples from two regional lake datasets in the
Northern Great Plains (NGP; n= 64) and West Greenland (n= 40) is assessed using a …

Understanding late Holocene to present relative sea-level changes at centennial or sub-
centennial scales requires geological records that dovetail with the instrumental era. Salt …

Benthic foraminifera are found in a wide range of environments and may at times be one of
few proxies available for the study of palaeoenvironmental conditions. However, the …

Geochemical proxies and diatom assemblages were used in combination with grain size
characteristics not only to describe the deposit left behind by the 27 February 2010, Maule …

Endemic planktonic diatoms are a major component of Lake Baikal sediments during
interglacial periods. To investigate how these diatom assemblages are altered during …
