1. 1. Marine Geology and Holocene Paleoceanographyof the Southern Quark, Baltic Sea

   University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

   Author : Anton Wagner; [2022]
   Keywords : Bottom currents; Sortable silt; Radiocarbon dating; Baltic Sea stages; Estuarine circulation; Marine sediment cores; Marine geophysical mapping;

   Abstract : The Understen-Märket trench is located in the Southern Quark and is the only deep-water connection between the Baltic Propper and the Gulf of Bothnia. Bathymetric mapping reveals a number of eroded channels and drift deposits exists on the seafloor, indicating that the area is heavily affected by current activity. READ MORE

   Abstract : The sediment Core SWERUS-L2-2-PC1 (2PC) retrieved from the Chukchi Sea, Arctic Ocean sits in an oceanographically dynamic location at the Arctic-Pacific Ocean gateway. The 8.3 m-long core was retrieved in Herald Canyon at the marginal ice zone at 57 m depth. READ MORE

4. 3. Quaternary Arctic foraminiferal isotopes: species reliability and palaeoceanographic application

   University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

   Author : Aron Varhelyi; [2018]
   Keywords : Palaeoceanography; Arctic; foraminifera; stable isotopes; Paleoceanografi; Arktis; foraminiferer; stabila isotoper;

   Abstract : To investigate whether foraminiferal stable isotope (δ18O/δ13C) variations have potential as a chronostratigraphic tool in the Arctic Ocean, this thesis presents new δ18O/δ13C data from five marine sediment cores. Three of those are downcore analyses (PS92/54-1; TC/PC-03; PC-07) and the remaining two are core top analyses (PC-04; PC-08). READ MORE

5. 4. The paleoceanography of Kattegat during the last deglaciation from benthic foraminiferal stable isotopes
