1. 1. Analysing seasonal snow cover trends and patterns on Svalbard

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Dhruv Maniktala; [2022]
   Keywords : snow cover; snow disappearance; snow onset; snow-free duration; CARRA; Svalbard;

   Abstract : Rapid warming in the Arctic is highly impacting the cryosphere in the region, causing melting of the sea ice, retreat of glaciers and reduction in the snow cover. If suffering further temperature increase, the albedo of the region would reduce due to higher absorption of the solar radiation in snow-free areas. READ MORE

3. 2. Effects of snow-free season, temperature and radiation variations on the retreat of Linné glacier, Svalbard

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Juliano Hanna; [2020]
   Keywords : Glacier; Arctic; Svalbard; climate change; GIS; drone; air temperature and solar radiation; Earth and Environmental Sciences;

   Abstract : Linné glacier has retreated approximately 1.8 km since 1936 and 1 km between 1995 and 2019. Linné glacier is following the same trend as other glaciers around Svalbard. Linné glacier is a well-monitored glacier with a time series of air temperature, incoming solar radiation and snow height data since 2003. READ MORE

4. 3. 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

5. 4. Impact of environmental variables on tundra vegetation onset of flowering explained by survival modelling

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Hanna Jonsson; [2019]
   Keywords : Flowering; Phenology; Cox proportional hazard model; Tundra; International tundra experiment; Climate change; Physical Geography and Ecosystem analysis; Earth and Environmental Sciences;

   Abstract : Timing of phenological events are highly related to climate and is one of the first signs of ecosystem responses to the climate change. Timing of flowering phenology is an important trait influencing the distribution and fitness of plants species. READ MORE

6. 5. Estimating the timing of animal and plant phenophases in a boreal landscape in Northern Sweden (Västerbotten) using camera traps

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

   Author : Sherry Young; [2018]
   Keywords : camera trapping; timing phenology; abiotic parameters; northern Sweden;

   Abstract : It is becoming more important to understand shifts in plant and animal phenology as climate is changing. However, the methods to study phenology used so far have shown to be limited over time and space. Therefore, a method such as camera traps is interesting to use since it bridges satellite remote sensing and on-ground observation methods. READ MORE
