Twentieth-century warming and hydrographical changes in the Tagus Prodelta, eastern North Atlantic
Pluri-annual proxy records of marine sediment cores from the Tagus Prodelta off Lisbon, Portugal, have been generated to gain insight into the climatic and hydrographic changes in the area during the twentieth century. The study includes benthic and planktonic foraminiferal faunas and the stable isotopic composition of one benthic ( Uvigerina celtica) and two planktonic ( Globigerina bulloides and Globorotalia inflata) foraminiferal species. Sea …
Radiocarbon Levels in the Iceland Sea from 25–53 kyr and their Link to the Earth's Magnetic Field Intensity
By correlating the climate records and radiocarbon ages of the planktonic foraminifera N. pachyderma (s) of deep-sea core PS2644 from the Iceland Sea with the annual-layer chronology of the GISP2 ice core, we obtained 80 marine 14 C calibration points for the interval 11.4-53.3 ka cal BP. Between 27 and 54 ka cal BP the continuous record of 14 C/cal age differences reveals three intervals of highly increased 14 C concentrations coincident with lo…
Correlation of Marine 14 C Ages from the Nordic Seas with the Gisp2 Isotope Record: Implications for 14 C Calibration Beyond 25 ka BP
We present two new high-resolution sediment records from the southwestern Iceland and Norwegian Seas that were dated by numerous 14 C ages up to 54 14 C ka bp. Based on various lines of evidence, the local 14 C reservoir effect was restricted to 400–1600 yr. The planktic stable isotope records reveal several meltwater spikes that were sampled with an average time resolution of 50 yr in PS2644 and 130 yr in core 23071 during isotope stage 3. Most …
