  2. 1. Development and use of an optical pCO2 sensor in marine studies

    Author : Dariia Atamanchuk; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pCO2; O2; sensor; optode; cross-sensitivity; carbonate system of seawater; biogeochemistry; Redfield ratio; the Koljo Fjord; cabled observatory; CCS; QICS; environmental engineering; leakage detection; MVDA; DoE;

    Abstract : Partial pressure of CO2 (pCO2) is one of the most important parameters, which are measured in the global ocean in conjunction with ocean acidification studies. It is also a parameter of great interest to aquaculture and fish industries since CO2 in large amounts is highly toxic for animals. The requirements for pCO2 measuring systems, e.g. READ MORE

  4. 2. The Carbon Dioxide System in the Baltic Sea Surface Waters

    Author : Karin Wesslander; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; carbon dioxide; pCO2; total alkalinity; pH; air-sea gas exchange; inter-annual; seasonal;

    Abstract : The concentration of carbon dioxide (CO2) in the atmosphere is steadily increasing because of human activities such as fossil fuel burning. To understand how this is affecting the planet, several pieces of knowledge of the CO2 system have to be investigated. READ MORE

  5. 3. Causes and consequences of Gonyostomum semen blooms

    Author : Karla Münzner; Eva S. Lindström; Lars J. Tranvik; Gesa A. Weyhenmeyer; Silke Langenheder; Ann-Kristin Bergström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gonyostomum semen; algal blooms; brown water lakes; lake browning; iron; dissolved organic carbon DOC ; carbon cycling; pCO2; CO2; organic matter; sedimentation; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Aquatic ecosystems provide essential ecosystem services, but are also highly vulnerable to global change. Climate change, eutrophication and browning, for example, collectively drive the increase of harmful algal blooms in freshwaters. READ MORE

  6. 4. Modelling the Dissolved Inorganic Carbon System in the Baltic Sea

    Author : Moa Edman; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; Kattegat; pH; pCO2; total alkalinity; biogeochemistry; dissolved inorganic carbon; eutrophication; acidification; climate change; numerical modelling;

    Abstract : Oceans are capable of storing part of the emitted anthropogenic carbon dioxide (CO2) due to the formation of carbonic acid and subsequent dissociation. CO2 is also assimilated by biota and the inorganic carbon system is thus coupled to biogeochemical processes. READ MORE

  7. 5. Organic carbon dynamics in the Baltic Sea : A modelling perspective

    Author : Filippa Fransner; Jonas Nycander; Christoph Humborg; Andreas Oschlies; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon cycle; organic carbon; primary production; remineralisation; terrestrial DOC; extracellular DOC; flexible stoichiometry; Redfield ratio; air-sea CO2 exchange; pCO2; coupled 3D physical-biogeochemical modelling; Gulf of Bothnia; Baltic Sea; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Coastal seas constitute a link between land and the open ocean, and therefore play an important role in the global carbon cycle. Large amounts of carbon, of both terrestrial and marine origin, transit and are transformed in these waters, which belong to the more productive areas of the oceans. READ MORE
