  1. 1. Thermal tolerance of native vs. invasive marine species at the Northern coast of Portugal

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sofie Michelsen; [2023]
    Keywords : Biodiversity; Climate change; Marine ecosystems; Marine heat waves; Intertidal environment; Invasive species; Macroalgae; Mussels; Sustainable Development; Thermal tolerance;

    Abstract : Two prominent factors posing a major threat to biodiversity in marine ecosystems are climate change and the establishment of invasive species, and the interaction between these two. Because of the upwelling of cold, nutrient-rich water, the coast of Portugal is a thermal refuge and distribution edge for cold-adapted species, making it a particularly important study area from a biodiversity point of view.

  3. 2. Cloud Observations at a Coastal site – Analysis of Ceilometer Measurements from Östergarnsholm, Sweden

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Aron Stenlid; [2019]
    Keywords : Ceilometer; Stratocumulus; cloud base height; LCL; DLS; upwelling; cloud cover;

    Abstract : In this study, four and a half months of ceilometer data from Östergarnsholm are used to analyze cloud related to processes in the boundary layer. Measurements are divided into two categories, which are defined by wind direction: a continental and a marine sector. READ MORE

  4. 3. Transcriptomic profiling of marine bacteria between development and senescence phases of a phytoplankton bloom

    University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Author : Dennis Amnebrink; [2018]
    Keywords : Transcriptomics; bacteria; microbes; DOM; marine environment; bioinformatics;

    Abstract : Bacterioplankton provide important ecosystem functions by carrying out biogeochemical cycling of organic matter. Playing an important role in the microbial loop they help remineralize carbon and nutrients. Bacteria also interact with phytoplankton during phytoplankton blooms. READ MORE

  5. 4. Towards Sustainable Use of Groundwater Resources: Aquifer 23, La Mancha-Spain.

    University essay from KTH/Mark- och vattenteknik

    Author : Pablo Doncel Fuentes; [2015]
    Keywords : Water scarcity; Water resources management; Aquifer carrying;

    Abstract : La Mancha Plain lies in the core of Spain and partially stretches over the Guadiana River Upper Basin (UGB), is one of the most arid regions of the Iberian Peninsula, indeed “La Mancha” in Arabic means “the dry”, and also houses a vast Aquifer that has supported the related numerous marshlands and hydro-ecosystems in harmony with the human development till the 1970s, when the “Agrarian Green Revolution” commenced. Land reclamation over River and lagoon beds joined to the irrigation implementation of more than 150. READ MORE

  6. 5. A comparsion of size fractions in faunal assemblages of deep-water benthic foraminifera : a case study from the coast of SW-Africa

    University essay from Lunds universitet/Geologiska institutionen

    Author : Oliver Björnfors; [2014]
    Keywords : Benthic; foraminifera; upwelling; size fraction; faunal assemblages; marine geology; Earth and Environmental Sciences;

    Abstract : Foraminifera are abundant in the marine sediment in all of the worlds’s oceans and offer a valuable proxy method to reconstruct water depth, circulation, productivity and deep water aeration. The choice of size fraction used when studying benthic foraminifera in upwelling areas are important. READ MORE
