  1. 21. 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

  3. 22. A spatiotemporal analysis of coral reef regimes and fish herbivory across the Hawaiian Archipelago

    Master-uppsats, Stockholms universitet/Stockholm Resilience Centre

    Författare :Emmy Wassénius; [2017]
    Nyckelord :Coral reef; Herbivory; Regime Shift; Hawaii; Functional space;

    Sammanfattning : Coral reefs can undergo shifts to alternative ecological regimes (or states) when exposed to stress. Acquiring a deeper understanding of when coral reefs become increasingly vulnerable to such shifts (i.e. LÄS MER

  4. 23. Defining The Geochemical Footprint For Gold Mineralisation Around Birthday Reef.Reefton Goldfield, New Zealand

    Master-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Jonathan Hamisi; [2016]
    Nyckelord :Orogenic gold; hydrothermal alteration; Reefton; mass changes; geochemical footprint; vectors; exploration; Blackwater;

    Sammanfattning : Abstract Orogenic gold deposits from the Reefton goldfield in New Zealand hosted in Ordovician metasediments of the Greenland group have produce 67 tons of gold before 1951. The Blackwater mine in Waiuta account for about 1/3 of the gold production at Reefton prior 1951. LÄS MER

  5. 24. Estimations of anthropogenic nutrient flows at the coral reef island Ko Sak, Thailand : A simplified source flow analysis

    Kandidat-uppsats, KTH/Industriell ekologi

    Författare :Emelie Lindström; Adam Engström; [2016]
    Nyckelord :;

    Sammanfattning : High levels of nutrients in tropical coastal areas is a big problem and poses large threats to coral reefs. Therefore this study will focus on nutrient flows from a source perspective. The aim of this study is to identify and quantify the phosphorus and nitrogen emissions from human activities at the island Ko Sak, Thailand. LÄS MER

  7. 25. Evaluation of methods to characterise the geochemistry of limestone and its fracturing in connection to heating

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Jessica Jennerheim; [2016]
    Nyckelord :geochemistry; limestone; Gotland; thermal properties; x-ray fluorescence; x-ray computed tomography; Earth and Environmental Sciences;

    Sammanfattning : Abstract: In 2011 Vinnova funded a joint project between Nordkalk AB, Kalkproduktion Storugns AB (KPAB) and the department of Geology at the University of Lund. The goal of the project is to increase the general knowledge of limestone and in extension, facilitate for the industry. LÄS MER
