Quaternary International, 1— Band 6 Ed. Naturwissenschaften — These fluctuations in Bay phytoplankton imply dynamic short-term variability in bay environments that must be related to natural variations in hydrological conditions. Part of the NATO ASI Series book series volume 27 Abstract Dinoflagellate cysts have, in the past, been a neglected microfossil group in the documentation and interpretation of climatic change.

In Wrenn, J. Furthermore, this study highlights four species potentially useful for correlating mid-latitude sequences to the Central Arctic Ocean.
Fisheries and Aquatic Sciences — Episodes, — The presence of plant communities dominated by NAP in the Pliocene may indicate that these sediments are younger than about 2.
These trends are also observed in dinoflagellate assemblages from other Chesapeake Bay cores Verardo and others, ; Willard and others, in prep.
Analysis[ edit ] Once samples have been prepared chemically, they are mounted on microscope slides using silicon oil, glycerol or glycerol-jelly and examined using light microscopy or mounted on a stub for scanning electron microscopy.

Most recently semi-quantitative statistical techniques, with the utilisation of simple indices and ratios, and quantitative transfer function analyses have been applied to dinoflagellate cyst data in order to derive sea-surface temperatures. Alternatively, the cyst may comprise a more or less spherical central body with processes or crests, and such cysts are termed chorate or proximochorate.

The palynological investigation of 30 outcrop samples from seven sites in and near the Qattara Depression, north Western Desert, Egypt, has yielded six samples from three sites containing poorly to well-preserved assemblages including dinoflagellate cysts, freshwater algae, acritarchs.
