  1. 1. Seagrasses in warming oceans physiological and biogeochemical responses

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Rushingisha George; Stockholms universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Global warming; greenhouse gas; warming oceans; temperate; tropical; coastal waters; Western Indian Ocean WIO ; tidal variability; seagrass; photosynthesis; respiration; photorespiration; biogeochemical processes; sulphide; methane; nitrous oxide; carbon dioxide; växtfysiologi; Plant Physiology;

    Abstract : The exponential increase of atmospheric greenhouse gas concentrations over the past 50 years has caused a rise in the global average temperature by more than 1ºC above pre-industrial levels. Ninety-three percent of this heat energy has been absorbed and stored by the oceans, increasing their temperatures, particularly in surface waters. READ MORE

  2. 2. Iodine Isotopes and their Species in Surface Water from the North Sea to the Northeastern Atlantic Ocean

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Peng He; Uppsala universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; iodine isotopes; 129I; 127I; oceans; North Sea; speciation; Atlantic Ocean; English Channel; Celtic Sea; AMS; iodine chemistry; geochemistry; Geovetenskap med inriktning mot miljöanalys; Earth Science with specialization in Environmental Analysis;

    Abstract : Huge amounts of anthropogenic 129I have been and still are released to the environment through liquid and gaseous discharges from the nuclear fuel reprocessing facilities worldwide and in particular the ones in Europe. Most of this 129I signal has been accumulated in the marine environment which plays a major role in the iodine natural pool. READ MORE

  3. 3. Are you ready for a wet live-in? explorations into listening

    University dissertation from Umeå; Lund : Umeå University; Lund University

    Author : Janna Holmstedt; Umeå universitet.; [2017]
    Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; artistic research; listening; situated practices; sound in art; expanded art; expanded scenography; media ecology; acousmatic orality; a orality; storytelling; interspecies communication; more-than-human relations; co-habitation; sensorial estrangement; posthumanism; parasites; play; technology; dolphins; sonic sensibility; transliteracy; voice; performativity; new materialism; Michel Serres; Karen Barad; John Lilly; oceans; wet live-in;

    Abstract : Listen. If I ask you to listen, what is it that I ask of you—that you will understand, or perhaps obey? Or is it some sort of readiness that is requested? What occurs with a body in the act of listening? How do sound and voice structure audio-visual-spatial relations in concrete situations?This doctoral thesis in fine arts consists of six artworks and an essay that documents the research process, or rather, acts as a travelogue as it stages and narrates a series of journeys into a predominantly sonic ecology.

  4. 4. Acoustic characterization of submarine geomorphological features in the Polar Oceans

    University dissertation from Stockholm : Department of Geological Sciences, Stockholm University

    Author : Francis Freire; Stockholms universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Marine glacial environments contain unique seafloor features resulting from the dynamic glacial processes. Studying these submarine geomorphological features can help us understand the glacial paleo-environments so that we can predict the likely responses of present day glaciers and ice sheets to future changes in the climate.

  5. 5. Exploration of microbial diversity and evolution through cultivation independent phylogenomics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Joran Martijn; Uppsala universitet.; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cultivation independent genomics; metagenomics; single-cell genomics; metagenomic binning; phylogenetics; phylogenomics; phylogenetic artefacts; comparative genomics; gene tree-species tree reconciliation; rRNA amplicon sequencing; Tara Oceans; origin of mitochondria; Alphaproteobacteria; Rickettsiales; Haloarchaea; endosymbiosis; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : Our understanding of microbial evolution is largely dependent on available genomic data of diverse organisms. Yet, genome-sequencing efforts have mostly ignored the diverse uncultivable majority in favor of cultivable and sociologically relevant organisms. READ MORE
