1. Modelling gross primary production in semi-arid regions: effects on carbon uptake of intensive agriculture in southern KenyaMaster-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap
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
2. Assessing annual forest phenology: a comparison of Unmanned Aerial Vehicle (UAV) and phenocamera datasetsMaster-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap
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.

3. A Scalable Approach for Detecting Dumpsites using Automatic Target Recognition with Feature Selection and SVM through Satellite ImageryUppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktion
Sammanfattning : Throughout the world, there is a great demand to map out the increasing environmental changes and life habitats on Earth. The vast majority of Earth Observations today, are collected using satellites. LÄS MER
- Master-uppsats, Lunds universitet/Geologiska institutionen
Sammanfattning : This study presents a detailed investigation into the evolution of sedimentary landforms over an ablation season at Blåisen, an outlet of the Hardangerjøkulen Icecap, Norway. The two visits to Blåisen, one each side of the ablation season, allowed the preservation and evolution of the landforms to be studied. LÄS MER
5. Submesoscale variations in sea surface temperature and salinity - a comparison between satellite data and in situ measurements from a mobile platformKandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap
Sammanfattning : 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. LÄS MER
