  1. 1. Carbon emission allocation of Ro-Pax ferry transport and the application for ferry companies

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Qiutong Xu; [2023]
    Keywords : CO2 emissions; Emission allocation; Ro-Pax ferry; Ferry transport; Passenger; Freight; CO2-utsläpp; Utsläppsfördelning; Ro-Pax-färja; Färjetransport; Passagerare; Frakt;

    Abstract : The EU has set up the target of cutting GHG emissions by at least 55% by 2030 and becoming climateneutral by 2050. Accordingly, the IMO has launched initiatives to reduce CO2 emissions per transportwork by at least 40% by 2030, however the CO2 emissions generated from the ferry operations arecontinuously increasing.

  3. 2. Biochar from separated digestate and pig manure as soil amendment

    University essay from SLU/Dept. of Soil and Environment

    Author : Lovisa Nissen; [2022]
    Keywords : separation; screw press; incubation study; CO2 emission; N mineralization;

    Abstract : The situation in and around the Baltic Sea, with large areas with hypoxia in the sea and areas in the watershed with a high concentration of animal farms, has led to a need to increase the nutrient recycling of animal manure. High levels of phosphorus (P) in the soil lead to leaching, and by reducing the P-level in organic fertilizers, this leaching can be reduced. READ MORE

  4. 3. Co-occurence and co-metabolism of phototrophic and heterotrophic microbial communities in the Baltic Sea

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Cátia Ifigénia Corujo Chaves; [2017]
    Keywords : microbiology; extracelullar enzymatic activity; amplicon sequencing; 16S and 18S sequencing;

    Abstract : In the marine water column, microbial autotrophs and heterotrophs coexist forming the beginning of the food chain which sustains the whole biological system. Both groups play a vital role in the microbial loop. READ MORE

  5. 4. Control of marine plankton respiration : High temperature sensitivity at low temperatures influenced by substrate availability

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

    Author : Katharina Amundsson; [2016]
    Keywords : plankton respiration; temperature; substrate; limiting factors; Q10; Baltic Sea;

    Abstract : Temperature dependence of marine plankton respiration is an important factor in understanding the function and changes in the ecosystem of the ocean. The aim of this study is to test the temperature sensitivity (Q10) of plankton respiration. The oxygen optode method was used to measure plankton respiration. READ MORE

  6. 5. Global Sensitivity of Water Quality Modeling in the Gulf of Finland.

    University essay from KTH/Mark- och vattenteknik

    Author : Daorui Lin; [2015]
    Keywords : Gulf of Finland; Eutrophication; Modelling; Morris sampling; Sensitivity analysis;

    Abstract : The Gulf of Finland is the most eutrophied water body in the Baltic Sea, which is mainly caused by nutrient loads produced by human activities in its surrounding cities. In order to solve this environmental problem, a computational model based on the understanding the relations between eutrophication, water quality and sediments is needed to forecast the water quality variance in response to the natural and anthropogenic influences.
