2. 1. Waterborne Carbon in Northern Streams : Controls on dissolved carbon transport across sub-arctic Scandinavia

   Author : Elin Jantze; Steve W. Lyon; Georgia Destouni; Helen Dahlke; Pirkko Kortelainen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; dissolved carbon; DOC; DIC; TOC; sub-arctic; hydrology; Abisko; Physical Geography; naturgeografi;

   Abstract : Waterborne carbon (C) forms an active and significant part of the global C cycle, which is important in theArctic where greater temperature increases and variability are anticipated relative to the rest of the globe withpotential implications for the C cycle. Understanding and quantification of the current processes governing themovement of C by connecting terrestrial and marine systems is necessary to better estimate future changes ofwaterborne C.

4. 2. Impacts of global change on primary production in northern lakes

   Author : Isolde Callisto Puts; Ann-Kristin Bergström; Jenny Ask; Tom H. Andersen; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Primary production; global change; warming; browning; lake; carbon dioxide; organic carbon; inorganic carbon; boreal; arctic; DOC; DIC; CO2; allochthonous organic carbon; benthic; periphyton; environmental change; miljöförändringar; environmental science; miljövetenskap; biology; biologi; climate change; klimatförändringar;

   Abstract : Algae are primary producers, a major component of the aquatic foodweb, and changes in primary production affect aquatic ecology in general. Global changes such as warming, recovery of acidification and changes in land-use have caused warming and browning of northern lakes. READ MORE

5. 3. The role of inland waters in the carbon cycle at high latitudes

   Author : Erik Lundin; Jan Karlsson; Reiner Giesler; Robert Striegl; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; lakes; streams; carbon C ; carbon dioxide CO2 ; methane CH4 ; dissolved inorganic carbon DIC ; boreal; sub-arctic; arctic; emission; sediments; burial; budget; limnologi; Limnology; Earth Sciences with Specialization Environmental Analysis; geovetenskap med inriktning mot miljöanalys; naturgeografi; Physical Geography;

   Abstract : Understanding the drivers of climate change requires knowledge about the global carbon (C) cycle. Although inland waters play an important role in the C cycle by emitting and burying C, streams and lakes are in general overlooked in bottom-up approached C budgets. READ MORE

6. 4. Beyond carbon-limitation : A re-evaluation of the ecological role of photorespiration and direct oxygen photoreduction in seagrasses

   Author : Pimchanok Buapet; Mats Björk; Ilana Berman-Frank; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon limitation; Chlorophyll fluorescence; Electron transport rate; Irradiance; Mehler reaction; Non-photochemical quenching; Photorespiration; Photosynthetic activity; Plant Physiology; växtfysiologi;

   Abstract : Seagrasses living in shallow coastal waters are regularly subjected to changes in environmental conditions including the two essential factors for photosynthesis: dissolved inorganic carbon (DIC) and irradiance. This thesis focuses on the photosynthetic responses of seagrasses to carbon limitation induced by community metabolism and/or high light intensities. READ MORE

7. 5. Carbon Dynamics in Northern Marginal Seas

   Author : Sofia Hjalmarsson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; dissolved inorganic carbon; total alkalinity; continental shelf pump; marginal seas; Baltic Sea; Skagerrak; Laptev Sea; East Siberian Sea; Chukchi Sea;

   Abstract : The marginal seas have, despite their relatively small area, an important role in the global carbon cycle. They are largely influenced by carbon and nutrient fluxes from land and a large part of the biological production occurs in the marginal seas. READ MORE
