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 @ Marine Micropaleontology Eastern equatorial Pacific benthic foraminiferal distribution and deep water temperature changes during the early to middle Miocene Author(s) Karlos G.D. Kochhann, Ann Holbourn, Wolfgang Kuhnt, Jian Xu Abstract: We investigate changes in benthic foraminiferal assemblages and estimate bottom water temperatures (BWT), based on Mg/Ca ratios of Oridorsalis umbonatus, over three selected intervals of major climate change during the late early to middle Miocene at Integrated Ocean

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

D. Ramos, N. F. Goodkin, F. P. Siringan, K. Hughen Abstract: The Indo-Pacific coral Diploastrea heliopora reveals regional multi-decadal to centennial scale climate variability using coral carbonate δ18O (δ18Oc) as a combined proxy for sea surface temperature (SST)

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

Insects and Catfishes | New Species Reported this week

The week that just ended was particularly poor in descriptions of new species. The new species reported come from Egypt and China, are only two: a vertebrate (new genera and new species of catfish) and an invertebrate (new species of an insect). Full account of fossil species reported this week: Qarmoutus hitanensis, gen. et sp. nov., a new marine catfish (Siluriformes; Ariidae) from the upper Eocene Birket Qarun Formation, Wadi El-Hitan, Egypt, was reported in PLOS one (1st March 2017). Vitimoilus ovatus sp. nov., a Lower Cretaceous species of Cyrtophyllitinae (Insecta: Ensifera) from the Dabeigou Formation and Yixian Formation, China, was reported in Cretaceous Research (4th March 2017).
