   Author : Erik Browaldh; [2022]
   Keywords : diatoms; late holocene; SWERUS-L2-2-PC1; Herald Canyon; Chukchi Sea; ice-algae; sympagic; cryophilic; warm water diatom; Bering Sea Water species; bottom water temperature; BWT; benthic foraminifera; palaeothermometry; ice dynamics; Fragilariopsis; Fossula arctica; Paralia sulcata; Shionodiscus oestrupii; Thalassiosira simonsenii; Chaetoceros; Chaetoceros sp. 7;

   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

3. 2. Framtidens vattenvård : en kvantifiering av internbelastningen av fosfor i Vansjön och Nordsjön i Norduppland

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Caroline Agrillo; Jens Fölster Jens Fölster; [2021]
   Keywords : fosfor; internbelastning; eutrofiering; syrebrist; aluminiumbehandling; biomanipulation;

   Abstract : En kvantifiering av internbelastningen av fosfor gjordes i de eutrofierade sjöarna Vansjön och Nordsjön i Norduppland genom fysiokemisk mätning av vattnet och fraktionsanalys samt inkuberingsanalys av sediment. Mycket låga syrehalter mättes under vintern 2021 medan vattnet var övermättat på syre under våren detsamma året. READ MORE

4. 3. Hydrodynamic modelling of fate and transport of natural organic matter and per- and polyfluoroalkyl substances in Lake Ekoln

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Frida Ekman; [2021]
   Keywords : Ekoln; Natural organic matter NOM ; Total organic matter TOC ; Colour; degradation; sedimentation; photooxidation; PFAS; MIKE 3 FM; Ekoln; naturligt organiskt material NOM ; totalt organiskt kol TOC ; färg; nedbrytning; sedimentation; foto-oxidation; PFAS; MIKE 3 FM;

   Abstract : Societies are facing great challenges with obtaining a good quality and quantity of drinking water in the context of climate change. Increases in natural organic matter (NOM) and per- and polyfluoroalkyl substances (PFAS) have been observed in lakes and drinking water the past years, which is of great concern for water treatment plants in Sweden.

   Author : Johanna Forsvall; [2021]
   Keywords : Kombucha; Kombucha culture; Fermentation; Food engineering; Technology and Engineering;

   Abstract : The fermented tea beverage kombucha is a traditional drink that has been consumed for thousands of years in Asia. Over the past decades, it has gained greatly in popularity amongst consumers and researchers also in the rest of the world. READ MORE

6. 5. Hydrological catchment analysis from characterisation of organic matter in stream water

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Hannes Berg Wiklund; [2020-02-05]
   Keywords : Organic matter; Time-of-flight mass spectrometry; aquatic chemistry; catchment hydrology;

   Abstract : Organic matter (OM) in aquatic systems is a complex field which have rapidly developed during the last decade due to the introduction of high resolution mass spectrometers. The composition of OM in the aquatic environment is directly dependent on factors such as oxygen supply, pH and the flow rate in the local system. READ MORE
