Palaeoproductivity and post-depositional aerobic organic matter decay reflected by dinoflagellate cyst assemblages of the Eastern Mediterranean S1 sapropel
TL;DR: In this article, the authors investigated how organic and calcareous-walled dinoflagellate cysts can be used for separately estimating bioproductivity and oxygen related diagenesis.

Coccolith distribution patterns in South Atlantic and Southern Ocean surface sediments in relation to environmental gradients
TL;DR: In this study, the coccolith compositions of 213 surface sediment samples from the South Atlantic and Southern Ocean were analysed with respect to the environmental parameters of the overlying surface waters and the abundance patterns of the main species and their ecological affinities were ascertained.

Shifts in the position of the north equatorial current and rapid productivity changes in the western tropical Atlantic during the last glacial
Annemiek Vink,Carsten Rühlemann,Karin A F Zonneveld,Stefan Mulitza,Matthias Hüls,Helmut Willems +5 more
TL;DR: In this article, high-resolution, well-dated calcareous dinoflagellate cyst and organic carbon records from a 58 kyr sediment core (M35003-4) located southeast of the island of Grenada show that rapid and pronounced changes in cyst association and accumulation, controlled by a significant southward shift in the position of the North Equatorial Current during the last glacial period and the Younger Dryas cold interval and rapid changes in local productivity in marine isotopic stage 3 that are associated with variations in Orinoco River nutrient discharge and

Establishing an Agenda for Calcareous Dinoflagellate Research (Thoracosphaeraceae, Dinophyceae) including a nomenclatural synopsis of generic names
Malte Elbrächter,Marc Gottschling,Tania Hildebrand-Habel,Helmut Keupp,Rolf Kohring,Jane Lewis,K J Sebastian Meier,Marina Montresor,Michael Streng,Gerard J M Versteegh,Helmut Willems,Karin A F Zonneveld +11 more
TL;DR: Calcareous dinoflagellates are considered to be a monophyletic group of peridinoid taxa that have the potential to produce calcified exoskeletal structures during the life cycle, or that derive fro the fossil record through “cell reprograming”.

Calcareous dinoflagellate cysts in South and equatorial Atlantic surface sediments: diversity, distribution, ecology and potential for palaeoenvironmental reconstruction
TL;DR: In this paper, the authors focus on the complex, often non-linear, relationships between individual species' distributions and the physicochemical and trophic conditions of the overlying (sub)surface waters through the use of x-y graphs of cyst abundance vs. (sub-surface water environmental parameters, and detrended correspondence analyses.

Detrended correspondence analysis: an improved ordination technique
M. O. Hill,Hugh G. Gauch +1 more
TL;DR: DCA consistently gives the most interpretable ordination results, but as always the interpretation of results remains a matter of ecological insight and is improved by field experience and by integration of supplementary environmental data for the vegetation sample sites.

Upper-level circulation in the South Atlantic Ocean
Ray G. Peterson,Lothar Stramma +1 more
TL;DR: A literature survey of the South Atlantic's climate and its oceanic upper-layer circulation and meridional heat transport is presented in this article, focusing on those elements having greatest oceanic relevance, i.e., distributions of atmospheric sea level pressure, the wind fields they produce, and net surface energy fluxes.

TL;DR: In this paper, the authors discuss the spatial aspects of Dune meadow data and propose a cluster analysis method for the Dune data set, based on case-studies.

Changes in East Atlantic Deepwater Circulation over the last 30,000 years: Eight time slice reconstructions
Michael Sarnthein,Kyaw Winn,Simon Jung,Jean-Claude Duplessy,Laurent Labeyrie,Helmut Erlenkeuser,Gerald Ganssen +6 more
TL;DR: Using 95 epibenthic δ13C records, eight time slices were reconstructed to trace the distribution of east Atlantic deepwater and intermediate water masses over the last 30,000 years as discussed by the authors.

Use of proxies in paleoceanography : examples from the South Atlantic

TL;DR: In this paper, a tool for the reconstruction of surface water Stratification using Pteropod Shells as a record of sub-surface water conditions is presented. But the tool is limited to the South Atlantic and the Southern Ocean.
