  3. 3. Late Eocene through Oligocene calcareous nannofossils from the paleo-equatorial Pacific Ocean – taxonomy, preservation history, biochronology and evolution

    Författare :Teodora Blaj; Jan Backman; Jorijntje Henderiks; Isabella Raffi; Paul Bown; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; marine sediments; calcareous nannofossils; late Eocene; Oligocene; biochronology; evolution; morphometry; taxonomy; ODP Leg 199 Site 1218; paleo-equatorial Pacific Ocean; Historical geology and palaeontology; Historisk geologi och paleontologi; Marine Geoscience; marin geovetenskap;

    Sammanfattning : This study aims to unravel the ecological and evolutionary dynamics within the calcareous nannofossil communities at the Eocene/Oligocene (E/O) transition and during the Oligocene time when Cenozoic 'icehouse' conditions were established. The main question this study aims to answer is whether the changes in the nannofossil assemblages were controlled by intrinsic evolutionary trends or if the changes were controlled by environmental factors such as changes in temperature and nutrient availability in the surface water.

  4. 4. Holocene and Latest Glacial Paleoceanography in the North-Eastern Skagerrak

    Författare :Richard Gyllencreutz; Jan Backman; Eve Arnold; Reidulv Bøe; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Skagerrak; Holocene; sediment; chirp sonar; grain size; mineral magnetic properties; Earth sciences; Geovetenskap;

    Sammanfattning : Detailed information on past oceanographic and climatic changes is crucial for our understanding of natural climate variability and for the assessment of future climate variations. Sediments strongly influenced by the North Atlantic Current accumulate at high rates in the northeastern Skagerrak, forming a potential highresolution archive for information on past climatic and oceanographic processes and events.

  5. 5. Eastern equatorial Pacific bulk sediment properties and paleoceanography since the late Neogene

    Författare :Daniele Reghellin; Helen K. Coxall; Jan Backman; Gerald R. Dickens; Steve Hovan; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Paleoceanography; late Neogene; eastern equatorial Pacific; deep sea sediments; bulk sediment; stable isotopes; surface mixed layer; sediment physical properties; maringeologi; Marine Geology;

    Sammanfattning : Reconstructing eastern equatorial Pacific (EEP) oceanography since the late Neogene (about 8 million years ago, Ma) is a central topic in current paleoceanographic investigations. The reason for this is two-fold. LÄS MER
