1. 1. Geochemical and palaeomagnetic characteristics of a Swedish Holocene sediment sequence from Lake Storsjön, Jämtland

   University essay from Lunds universitet/Geologiska institutionen

   Author : Joakim Robygd; [2015]
   Keywords : Jämtland; geochemistry; palaeomagnetism; PSV; sedimentation rate; Holocene development; geochronology; climate change; Earth and Environmental Sciences;

   Abstract : As a part of a French-Swedish collaboration project to reconstruct middle to northern European climate variations during the Holocene, a sediment sequence from Lake Storsjön, Jämtland was retrieved and analysed for geochemical and palaeomagnetic properties. The subsampled sequence, composed of one freeze core and three Niederreiter piston cores, revealed information of both climatic, environmental and anthropogenic changes over the past 10,800 years.

3. 2. Exploring long-term trends in hypoxia (oxygen depletion) in Western Gotland Basin, the Baltic Sea

   University essay from Lunds universitet/Geologiska institutionen

   Author : Tianzhuo Liu; [2012]
   Keywords : Baltic Sea; hypoxia; lead analysis; lamination; mineral magnetism; loss on ignition; magnetotactic bacteria; Östersjön; hypoxi; bly analys; laminering; glödgningsförlust; magnetotactic bakterier; Earth and Environmental Sciences;

   Abstract : Övergödningen är ett av de största hoten mot Östersjöns miljö. Den orsakar inte bara algblomning under sommarhalvåret utan även syrebrist (hypoxi). Utbredningen av syrefria bottnar i Östersjön har ökat fyrfaldigt sedan 1960-talet till följd av ökade utsläpp av näringsämnen, så som fosfor och kväve. READ MORE
