Just out @ Boreas Subarctic Front migration at the Reykjanes Ridge during the mid- to late Holocene: evidence from planktic foraminifera Author(s) Kerstin Perner, Matthias Moros, Eystein Jansen, Antoon Kuijpers, Simon R. Troelstra, Maartin A. Prins Abstract: Expansion of fresh and sea-ice loaded surface waters from the Arctic Ocean into the sub-polar North Atlantic is suggested to modulate the northward heat transport within the North Atlantic Current (NAC). The Reykjanes Ridge

Just out | A multiproxy macrofossil record of Eemian palaeoenvironments from Klaksvík, the Faroe Islands @ Boreas

Just out @ Boreas A multiproxy macrofossil record of Eemian palaeoenvironments from Klaksvík, the Faroe Islands Author(s) Ole Bennike, Lars Hedenäs, Geoffrey Lemdahl, Peter Wiberg-Larsen Abstract: Studies of interglacial successions are critical to our understanding of the environmental history of an area. Analyses of macrofossil remains of plants and invertebrates from Eemian sediments exposed in a coastal cliff section at Borðoyarvík near Klaksvík, Bordoy, northeastern Faroe Islands, indicate that the

Ezat, Tine L. Rasmussen, David J. R. Thornalley, Jesper Olsen, Luke C. Skinner, Bärbel Hönisch, Jeroen Groeneveld Abstract: Formation of deep water in the high-latitude North Atlantic is important for the global meridional ocean circulation, and its variability in the past may have played

Just out | Meltwater pulse recorded in Last Interglacial mollusk shells from Bermuda @ Paleoceanography

Just out @ Paleoceanography Title:  Meltwater pulse recorded in Last Interglacial mollusk shells from Bermuda Author(s) Ian Z. Winkelstern, Mark P. Rowe, Kyger C. Lohmann, William F. Defliese, Sierra V. Petersen, Aaron W. Brewer Abstract: The warm climate of Bermuda today is modulated by the nearby presence of the Gulf Stream current. However, iceberg scours in the Florida Strait and the presence of ice-rafted debris in Bermuda Rise sediments indicate

Small, shy, but plentiful of paleobiogeographic information

The paleontological record on shallow facies of the islands in the middle of a wide ocean such as the Atlantic allows to better understand the paleobiogeography of certain species, in particular those that have an amphi-Atlantic distribution. This is the case for small encrusting barnacles (you really need to pay attention to the surface of the fossil coral heads to spot them) of the genus Ceratoconcha. Ranging in age from the

Dinoflagellate Cyst | New Evidence on Utility as Tracers

The use of organic proxies as a way of reconstructing ancient climates and environmental conditions is well-established in paleoclimatology, paleoecology, and paleogeography. The measurement of stable isotopes and trace metals in microfossil shells are, for example, one of the most recurrent techniques used to assess the geochemical conditions of early ecosystems and the configuration of ancient ecotones. Simply put, the environmental conditions upon which early microorganisms have developed influence the geochemical
