  1. 1. Seasonal community dynamics of macroinvertebrates in an Arctic stream

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Ellinor Jakobsson; [2019]
    Keywords : Macroinvertebrates; Arctic; seasonality; community composition; Abisko;

    Abstract : Arctic ecosystems are amongst the most vulnerable on Earth to ongoing climate change. While the responses to these changes are well studied on land, less is known about how aquatic communities may respond to a warmer arctic. READ MORE

    Author : Alicja Miodonska; [2019]
    Keywords : remote sensing; multispectral satellite imagery; Landsat; Iceland; glaciers; ice caps; Geography; GIS; Earth and Environmental Sciences;

    Abstract : The study focuses on the application of multispectral satellite imageries in glaciological studies. It aims to assess how the Icelandic glaciers have evolved over the last decades (from the 1980s to 2014). The study area covers Mýrdalsjökull and Eyjafjallajökull ice caps located in Suðurland, Iceland. READ MORE

  5. 5. 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
