  1. 1. Submesoscale variations in sea surface temperature and salinity - a comparison between satellite data and in situ measurements from a mobile platform

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Kerstin Bergentz; [2020]
    Keywords : Earth and Environmental Sciences;

    Abstract : Sea surface temperature and salinity are important variables for understanding many ocean and climate processes. They can be measured both by in situ sensors and satellite remote sensing, each method with its own advantages and disadvantages. READ MORE

  2. 2. Spatial and temporal variations in stable isotope signatures (δ13C and δ15N) of the gammarids and the common carp in the southern coast of the Caspian Sea

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Nazila Hajizadeh Koupayeh; [2020]
    Keywords : carbon stable isotope; Caspian sea; Cyprinus carpio; food webs; Gammarus aequicauda; nitrogen stable isotope; Pontogammarus maeoticus;

    Abstract : Despite the growing body of research on the use of stable isotope analysis in food web studies, spatial and temporal variations in stable isotope ratios of coastal communities are still poorly understood. The aim of my study is to explore how carbon and nitrogen stable isotopes of selected benthic communities vary spatially and temporally across the south of Caspian Sea. READ MORE

  3. 3. Dietary preferences of Golden eagles (Aquila chrysaetos) in Sweden : a camera trap approach

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Tomas Melin; [2020]
    Keywords : Aquilla chrysaetos; breeding; camera trap; Golden eagle; nestling; prey; Sweden;

    Abstract : Food availability and suitable habitat are necessary for reproductive success of raptors. Monitoring these variables may therefore provide important insights on fitness and population dynamics of species such as the golden eagle (Aquila chrysaetos), which are often very difficult to monitor.

  4. 4. The Local Effect of Oil on Women's Employment and Empowerment - Evidence from Africa

    University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Author : Nadja Friedl; Sailee Sakhardande; [2020]
    Keywords : Local Impact of Natural Resources; Oil; Employment; Female Empowerment; Africa;

    Abstract : Does oil extraction impact local communities in developing countries? The socio-economic ramifications of oil extraction on the local population are not clear a priori. Recent evidence pointing towards a gender-differential impact of natural resources motivates an analysis focused on women. READ MORE

  5. 5. Indoor and Outdoor Measurements of Particulate Matter with the Low-Cost Optical Sensor OPC-N3

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Ellen Grace Soroka; [2020]
    Keywords : Physics and Astronomy;

    Abstract : This paper evaluates the low-cost optical sensor OPC-N3 from Alphasense as a suitable scientific instrument for measuring particulate matter levels in air, both outdoors and in- doors. The time-keeping and data-retrieval was additionally improved by connecting the OPC-N3 to an Arduino microcontroller equipped with a real-time clock (RTC) module and an external SD card. READ MORE
