1. 1. Impact of Sea Surface Temperature and Salinity on Phytoplankton blooms phenology in the North Sea

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Krystyna Muszel; [2023]
   Keywords : Geography; GIS; North Sea; phytoplankton; bloom; phenology; remote sensing; TIMESAT software; Earth and Environmental Sciences;

   Abstract : Various environmental forcings can affect phytoplankton blooms, resulting in changes in bloom timing and abundance, which can have many far-reaching consequences. Understanding bloom phenology is crucial to predict and counter any potential harmful changes. READ MORE

3. 2. Vegetation phenology derived using the plant phenology index and the normalized difference vegetation index for the Balkan peninsula, south-eastern Europe

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Aleksandra Ivanova; [2019]
   Keywords : physical geography; ecosystem analysis; phenology; vegetation; climate change; remote sensing; plant phenology index; PPI; timesat; Balkan peninsula; Earth and Environmental Sciences;

   Abstract : This study analyses the performance of the satellite derived Plant Phenology Index (PPI) against the Normalized Difference Vegetation Index (NDVI) for estimating start of season (SOS) and end of season (EOS) of vegetation growth in part of the Balkan Peninsula, Southeastern Europe (2000 – 2016). Results revealed that PPI and NDVI differ considerably; SOS and EOS may diverge by more than one month between the two indices. READ MORE

4. 3. Land Surface Phenology as an indicator of performance of conservation policies like Natura2000

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Gunjan Sharma; [2016]
   Keywords : MODIS NDVI; Natura2000; Land Surface Phenology LSP ; ecological indicators; TIMESAT; trend analysis; GEM; Earth and Environmental Sciences;

   Abstract : Considering the growing pressure on various ecosystems all around the world, the development of ecological indicators for assessing the health and condition of the ecosystems has become an integral part of environmental management and policy making efforts. Such indicators do not only simplify the complex ecosystem processes but can also act as a measure of performance of a conservation policy. READ MORE

5. 4. Relationship between tree species composition and phenology extracted from satellite data in Swedish forests

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Stefan Arvidsson; [2015]
   Keywords : MODIS; forests mapping; fractional mapping; satellite derived phenology; GIS; Physical Geography and Ecosystem analysis; TIMESAT; NDVI; EVI; Earth and Environmental Sciences;

   Abstract : This study investigated the “relationship between tree species composition and phenology extracted from satellite data in Swedish forests”. The proposed method investigated in this study aims at mapping the fractional composition of deciduous/coniferous tree species and also the fractional composition of Norway spruce (Picea abies) and several pine (Pinus sp.

6. 5. Mapping moth induced birch forest damage in northern Sweden, with MODIS satellite data

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Kristian Morin; [2013]
   Keywords : physical geography; topography; TIMESAT; Epirrita autumnata; geometrids; time series; MODIS; remote sensing; geography; birch forest; Earth and Environmental Sciences;

   Abstract : Large synchronous outbreaks of herbivory geometrids is regularly occurring at 9-10 years intervals when they reach peak densities in the Fennoscandian birch forest, in the northern part of Scandinavia (Tenow 1972, Bylund 1995). Climate change is likely to increase the frequency, intensity and extent of the outbreak due to increasing temperatures in the area (Callaghan 2010, Heliasz et al. READ MORE
