  3. 2. Cell Size Variation in Fossil Coccolithophores (Haptophyta) : A Study of Pliocene Sediments from Northwestern Australia

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Nicole Eliassen; [2018]
    Nyckelord :Coccolithophore; cell; carbon cycle; Australia; palaeobiology; climate change.; Fästalger Haptophyta ; kokkolitoforider; Pliocen; cell; kolcykel; Australien; paleobiologi; klimatförändring;

    Sammanfattning : This report examines the size variations of fossil carbonate-producing haptophyte microalgae, coccolithophores, using sediments deposited during the Pliocene. The sediments were collected by the International Ocean Discovery Program (IODP) in 2015, off the coast of NW Australia (Gallagher et al., 2017). LÄS MER

  4. 3. Magmatic Sources and Processes Recorded by the Volcanics from the Izu Bonin Rear Arc

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :John Owen Edgar; [2017]
    Nyckelord :Izu-Bonin; plagioclase; magma; strontium; thermobarometry; rear arc; Izu-Bonin; plagioklas; magma; strontium; termobarometri; bakbåge;

    Sammanfattning : The Izu rear-arc volcanism was investigated by IODP EXP350 in spring 2014. A total stratigraphy of1800 m was drilled, and contains volcaniclastic material within tuffaceous mudstone. LÄS MER

  5. 4. Size and Abundance of Late Pleistocene Reticulofenestrid Coccoliths from the Eastern Indian Ocean in Relation to Temperature and Aridity

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Jeroen van Dijk; [2017]
    Nyckelord :coccoliths; abundance; biometry; circular polarized light microscopy; Late Pleistocene; Marine Isotope Stage 11; kokkoliter; mängder; biometri; cirkulär polariserat ljus; pleistocen; Marine Isotope Stage 11;

    Sammanfattning : Measurements on coccolith abundance and mass can be used as a signal of primary productivity and pelagic calcification in response to environmental change. The Leeuwin Current (LC) is known to transport warm and low-salinity waters from the Indo-Pacific Warm Pool (IPWP) southwards along the coast of West Australia. LÄS MER

  7. 5. Cenozoic history of North Atlantic deep sea carbonate preservation

    Kandidat-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Marcus Länje; [2015]
    Nyckelord :Carbonate compensation depth; CCD; IODP; ODP; DSDP; Atlantic Ocean; subsidence modeling; Cenozoic; database of sediment lithologies; Google Earth;

    Sammanfattning : Carbonate preservation in the oceans occurs at a depth called the carbonate compensation depth (CCD). The CCD is where the input rate of carbonate from the surface of the ocean is balanced by the dissolution rate. LÄS MER
