  1. 1. Cropland and tree cover mapping using Sentinel-2 data in an agroforestry landscape, Burkina Faso

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Ntandokazi Masimula; [2020-06-29]
    Keywords : Sentinel-2; Cropland mask; Tree cover estimation; Burkina Faso; Agroforestry; Random Forest;

    Abstract : Sentinel-2, with high spatial resolution bands and increased number of spectral channels,has provided increased capabilities for vegetation mapping. Cropland masks withinheterogeneous areas such as the Sudano-Sahel zone have become useful for monitoringlandscapes. READ MORE

  2. 2. Assessing annual forest phenology: a comparison of Unmanned Aerial Vehicle (UAV) and phenocamera datasets

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Shangharsha Thapa; [2020]
    Keywords : Geography; Ecosystem Analysis; Near-surface Remote Sensing; UAV; Phenocamera; Forest Phenology; Phenophase; Seasonality; NDVI; GCC; Geomatics; Earth and Environmental Sciences;

    Abstract : Near-surface remote sensing platforms such as Unmanned Aerial Vehicles (UAVs) and phenocameras appear to be potential platforms for keeping track of seasonal dynamics at a local scale. This research focusses on extracting time series of different vegetation indices (VIs) from both platforms, computing seasonality events from them and comparing the results against spectral sensor data.

  3. 3. Putting behavioral assays on fish to the test: Are sociality and scototaxis trials relevant in the wild?

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

    Author : Arno Veenstra; [2020]
    Keywords : Acoustic telemetry; Social network; Sociality; Scototaxis; Migration;

    Abstract : Animal behavior has become a frequently used tool in modern ecology and ecotoxicology, where laboratory behavioral traits are recognized as sensitive endpoints for assessing natural behavior or non-lethal effects of pollutants on animals. Within these research fields, behavioral traits measured in laboratory environments have been used to formulate predictions of ecological consequences that accompany specific behavior. READ MORE

  4. 4. 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

  5. 5. Automatic Characterisation of Magnetic Indices with Artificial Intelligence

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Veronika Haberle; [2020]
    Keywords : artificial intelligence; magnetic indices; magnetically quiet periods; geomagnetic field;

    Abstract : The complex interactions between the Sun and Earth are referred to as Space Weather. Key parameters include magnetic indices which quantitatively describe geomagnetic activity by determining a baseline that removes the background magnetic field and allows quantification of the remaining activity during geomagnetic events.
