1. 1. 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

3. 2. 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
