Dynamics of Manganese and Cerium Enrichments in Arctic Ocean Sediments: A Case Study From the Alpha Ridge

Frontiers in Earth Science, 2019
Manganese (Mn) and cerium (Ce) are known as reactive metals sensitive to marine redox conditions, and can therefore serve as useful proxies for paleoceanographic environments. Quaternary sedimentary records in the Arctic Ocean show a consistent cyclicity

Holocene vegetation dynamics of Grande Terre (Kerguelen Islands) inferred from sedimentary ancient DNA

Journal of Quaternary Science, EarlyView.
ABSTRACT While the Antarctic region has experienced significant climatic changes over the Holocene, few high‐resolution records have examined their effects on the local biota. In order to understand past ecological shifts and forecast future changes, it is important to obtain high‐resolution palaeoecological records from this region.

The sedimentary record of dinoflagellate cysts: looking back into the future of phytoplankton blooms

Scientia Marina, 2001
Marine systems are not as well understood as terrestrial systems, and there is still a great need for more primary observations, in the tradition of the old-time naturalists, before newer methods such as molecular genetics and modeling can be fully ...

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

Journal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

A talus rock glacier in Nantlle Valley, North Wales

Journal of Quaternary Science, EarlyView.
ABSTRACT Landforms comprising mixtures of fine and coarse sediment and deposited during late glacial times are ubiquitous in the British mountains. In many cases, their interpretation has often proved contentious; as a result, the non‐generic term discrete debris accumulations (DDA) has been used to describe them and, over the last 50 years, some have ...
