3. 2. 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
