  2. 2. Modelling gross primary production in semi-arid regions: effects on carbon uptake of intensive agriculture in southern Kenya

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Malin Ahlbäck; [2020]
    Nyckelord :Physical Geography; Ecosystem Analysis; GPP; Africa; Kenya; Land cover changes; Cropland; Remote sensing; Sentinel-2; Earth and Environmental Sciences;

    Sammanfattning : Background and aim: Gross primary production (GPP) is the largest global carbon (C) flux and an important component for counteracting anthropogenic CO2 emissions, understanding vegetation dynamics, and sustaining universal human standards. Africa plays a prominent role in the global C cycle, though our understanding of GPP dynamics is largely hampered by a paucity of ground-based observations. LÄS MER

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

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Sammanfattning : 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.

  4. 4. Analysing the controls over DOM quality in two contrasting sub polar marine environments

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Chiara Monforte; [2020]
    Nyckelord :DOM optical properties; Absorbance; Fluorescence; EEMs; Burdwood Bank; Beagle Channel; Earth and Environmental Sciences;

    Sammanfattning : In this study, Dissolved Organic Matter (DOM) quality was analysed through its optical properties. Samples from the estuarine waters of the Beagle Channel and oceanic ones of the Burdwood Bank were examined in order to understand how DOM quality was changing. LÄS MER

  5. 5. Soil organic carbon prediction using Sentinel-2 data and the LUCAS topsoil database

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Philipp Hansen; [2020]
    Nyckelord :Sentinel-2 LUCAS topsoil database Soil organic carbon mapping Multispectral data; Earth and Environmental Sciences;

    Sammanfattning : Its carbon sink potential as well as soil fertility benefits make organic carbon a soil variable for which reliable quantification methods are sought. This thesis work aims at investigating the possibility of adapting a large soil spectral library to build models for SOC predictions with remotely sensed, multispectral data. LÄS MER
