  1. 1. Greenhouse gas emissions and carbon burial in a small pond

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Maria Carlson; [2023]
    Keywords : Pond; greenhouse gas; carbon dioxide; methane; nitrous oxide; flux; ebullition; carbon burial; Damm; växthusgas; koldioxid; metan; lustgas; flöde; ebullition; kolbindning;

    Abstract : There are a lot of uncertainties when it comes to global greenhouse gas (GHG) emissions which affects society’s ability to effectively respond to climate change. Small ponds have been found to potentially play a large role in global warming. READ MORE

  3. 2. Methane Sulphonic Acid in East Antarctic Coastal Firn and Ice Cores and Its Relationship with Chlorophyll-a and Sea Ice Extent in the Southern Ocean

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Emma Nilsson; [2022]
    Keywords : methane sulphonic acid; firn cores; sea ice proxy; marine primary productivity; Fimbul Ice Shelf; Dronning Maud Land; metansulfonsyra; firnkärnor; havsis-proxy; marin primärproduktion; Fimbulisen; Dronning Maud Land;

    Abstract : The seasonal retreat of sea ice in the austral spring and summer around Antarctica has a significant effect on phytoplankton activity, mainly due to light availability, meltwater input of dissolved iron, and surface water stratification. Phytoplankton produce dimethylsulfoniopropionate, the precursor to the climate-cooling gas dimethyl sulphide, which is ventilated to the atmosphere and oxidised to methane sulphonic acid (MSA).

  4. 3. Application of data-driven models in exploring cyanobacterial bloom risks in Lake Mälaren

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Abigail Huertas Herrera; [2021]
    Keywords : Random Forest; blue-green algae; WHO Alert Level Framework; drinking water supply; cyanobacterial blooms;

    Abstract : Cyanobacteria are a unique organism, a bacterium that develop photosynthesis, thus it contains chlorophyll, a pigment commonly associated to algae. For this reason, cyanobacteria are also known as blue-green algae. One of the secondary metabolites of cyanobacteria is cyanotoxin, a substance which is hepatoxic, neurotoxic, and dermatoxic.

  5. 4. Design and implementation of embedded system for chl-a fluorescence detection

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Anargyros Katsogridakis; [2021]
    Keywords : Embedded systems; Microcontrollers; Harmful algal bloom; Climate change; chl-a fluorescence; Inbyggda system; mikrokontroller; skadlig algblomning; klimatförändring; chl-a-fluorescens;

    Abstract : Over the last decades, the effects of climate change have become increasingly evident across natural environments. Apart from other areas, climate change poses a serious threat on water quality. READ MORE

  6. 5. Satellitövervakning av cyanobakterieblomningar i sjöar : en jämförande studie för Mälaren

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

    Author : Patrik Hildén; [2021]
    Keywords : cyanobakterier; algblomning; klorofyll; fjärranalys; Mälaren;

    Abstract : Cyanobakterieblomningar ökar världen över och orsakar både ekonomiska förluster och hälsorelaterade problem. På grund av cyanobakteriers potentiellt skadliga inverkan sker regelbunden provtagning i svenska vatten. READ MORE
