2. 1. Dealing With Reservoir Effects in Human and Faunal Skeletal Remains : Understanding the radiocarbon dating of aquatic samples

   Author : Jack Dury; Gunilla Eriksson; Kerstin Lidén; Peter Jordan; Johannes van der Plicht; Philippa Ascough; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Radiocarbon Dating; Reservoir Effects; Bayesian; Modelling; Palaeodiet; Stable Isotopes; Skeletal Remains; Collagen; arkeologi med inriktning mot laborativ arkeologi; Scientific Archaeology;

   Abstract : Archaeology relies on the ordering of past events to study cultural developments. This has traditionally been achieved by looking at the stratigraphic depths of materials relative to one another. In this way, chronologies of past technological progressions and stylistic changes can be built. READ MORE

4. 2. Norm and difference : Stone Age dietary practice in the Baltic region

   Author : Gunilla Eriksson; Kerstin Lidén; Birgit Arrhenius; Michael Richards; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; diet; norm; variation; Mesolithic; Neolithic; Sweden; Latvia; stable carbon and nitrogen isotopes; radiocarbon; reservoir effect; dogs; breastfeeding; gender; Archaeology subjects; Arkeologiämnen;

   Abstract : Stone Age research on Northern Europe frequently makes gross generalizations about the Mesolithic and Neolithic, although we still lack much basic knowledge on how the people lived. The transition from the Mesolithic to the Neolithic in Europe has been described as a radical shift from an economy dominated by marine resources to one solely dependent on farming. READ MORE

5. 3. Molecular and isotopic characterization of terrestrial organic carbon released to (sub-)Arctic coastal waters

   Author : Jorien Elisabeth Vonk; Örjan Gustafsson; Jason Neff; Stockholms universitet; []
   Keywords : organic carbon; terrestrial biomarkers; radiocarbon; particulate organic carbon; sediments; sphagnum; Arctic; Bothnian Bay; East Siberian Sea; Kalix River; Kolyma River; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : Arctic soils store half of the global soil organic carbon (OC) pool and twice as much C as is currently present in the atmosphere. A considerable part of these carbon pools are stored in permafrost. READ MORE

6. 4. Testing palaeomagnetic and 14C based geochronological methods in the Baltic Sea

   Author : Bryan Lougheed; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; coastal; geochronology; palaeomagnetic secular variation; PSV; radiocarbon; 14C; reservoir age; R t ; ΔR; salinity; δ18O; geomagnetic field; Holocene; deglacial; Fennoscandia.;

   Abstract : The Baltic Sea is a continental shelf sea that is influenced by both river runoff and marine water. The two water masses are vertically stratified in the Baltic Sea, resulting in a positive, estuarine circulation system, which has undergone changes in the past due to isostatic uplift of the Baltic basin.

7. 5. Isotope-based constraints on sources and processing of black carbon, carbon monoxide, and brown carbon in South Asia

   Author : Sanjeev Dasari; Örjan Gustafsson; August Andersson; Jos Lelieveld; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; South Asia; Air Pollution; Short-Lived Pollutants; Atmospheric Abundance; Model-Observation Mismatch; Radiocarbon; Stable Isotopes; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : The highly populated South Asian region is facing rapid economic growth and urbanization. Here, both climate- and health-affecting atmospheric agents such as light-absorbing aerosols black carbon (BC) and brown carbon (BrC), trace gas carbon monoxide (CO), are often found in relatively high levels compared to in other regions.
