1. 1. Glacial geology and palaeo-ice dynamics of two ice-sheet margins, Taymyr Peninsula, Siberia and Jameson Land, East Greenland

   Författare :Helena Alexanderson; Kvartärgeologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ice dynamics; Pleistocene; Arctic Siberia; East Greenland; Sedimentology; Physical geography; Sedimentologi; pedology; geomorphology; klimatologi; kartografi; marklära; geomorfologi; cartography; Fysisk geografi; ice-marginal processes; glacial history; climatology;

   Sammanfattning : The North Taymyr ice-marginal zone (NTZ) on the Taymyr Peninsula, Arctic Siberia and the Ugleelv Valley on Jameson Land, East Greenland, have been investigated with the aim of reconstructing the glacial history, including depositional processes and environments. Geomorphological, sedimentological, stratigraphical and remote sensing methods have been combined to give a comprehensive view of developments in the two areas. LÄS MER

3. 2. Evolution and taxonomy of Cambrian arthropods from Greenland and Sweden

   Författare :Martin Stein; John S. Peel; Dieter Waloszek; David J. Siveter; Reinhardt M. Kristensen; David L. Bruton; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cambrian; Arthropods; Trilobites; Evolution; Greenland; Sweden; Historical geology and palaeontology; Historisk geologi och paleontologi;

   Sammanfattning : Arthropods have a rich fossil record spanning the Phanerozoic. Biomineralized forms such as the extinct trilobites are particularly common and are proven index fossils for biostratigraphy. Forms with an unmineralized cuticle are more rare, preserved only in so called konservat lagerstätten. LÄS MER

4. 3. The Early Cambrian Fauna of North-East Greenland

   Författare :Christian B. Skovsted; John S. Peel; Lars E. Holmer; Gerd Geyer; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Early Cambrian; Dyeran; Botoman; Biostratigraphy; Palaeogeography; Small Shelly Fossils; Brachiopoda; Mollusca; Hyolitha; Trilobita; Geovetenskap; Earth sciences; Geovetenskap;

   Sammanfattning : Small shelly fossils are common in sediments of Early Cambrian age and include the earliest common representatives of metazoan animals with mineralized hard parts. The group includes fossils of very different morphology, composition and ultrastructure. LÄS MER

5. 4. An integrated study of geological, magnetic and electromagnetic data for mineral exploration in the Jameson Land Basin, central East Greenland

   Författare :Anaïs Brethes; Thorkild Maack Rasmussen; Florian Wellmann; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; central East Greenland; Jameson Land Basin; base metal mineralization; geological structures; magnetic data; electromagnetic data; Prospekteringsgeofysik; Exploration Geophysics;

   Sammanfattning : The Jameson Land Basin, located in central East Greenland, initiated in Devonian time with the collapse of the over-thickened Caledonian Orogen. The basin developed during different phases of rifting from the late Paleozoic to the Mesozoic and has accumulated between 16-18 km of sediments. LÄS MER

7. 5. Genomic insights into the population history of circumpolar Arctic dogs

   Författare :Tatiana Richtman Feuerborn; Anders Hansen; Love Dalen; Mikkel Holger Strander Sinding; Kerstin Liden; Matthew Collins; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Dogs; Arctic; Inuit; Migration; Siberia; Greenland; Sled Dog; arkeologi med inriktning mot laborativ arkeologi; Scientific Archaeology;

   Sammanfattning : The Siberian and North American Arctic have both borne witness to numerous migrations of humans and with them their dogs. This PhD thesis is based on whole genome data from 22 Siberian dogs and 72 North American Arctic dogs, in addition to 186 mitochondrial genomes Siberian and North American Arctic dogs. LÄS MER
