  1. 16. The effect of the freshwater-sea transition on short-term dissolved organic carbon bio-reactivity : the case of Baltic Sea river mouths

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Sohidul Islam; [2014]
    Keywords : estuary; microbial community; nutrients; degradation; DOC; reactivity; bioavailability; physical geography and ecosystems science; Earth and Environmental Sciences;

    Abstract : Terrestrially-derived dissolved organic carbon (DOC) is transported to estuarine systems via river runoff, where it is largely degraded by microbial communities. I studied the combined influence of salinity (NaCl), microbial community (marine vs. READ MORE

  2. 17. The suitability of using Landsat TM-5 Images for estimating chromophoric dissolved organic matter in subarctic Lakes

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Julia Jakobsson; [2014]
    Keywords : CDOM; dissolved organic carbon; colored dissolved organic matter; Chromophoric; landsat thematic mapper 5; subarctic lakes; Stordalen; empirical algorithm.; Abisko; DOC; remote sensing; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

    Abstract : Recent trends of permafrost thawing in the subarctic are expected to cause increased release of dissolved organic carbon (DOC) to inland waters, which might have cascading effects on downstream aquatic ecosystems and release of CO2 to the atmosphere. This study therefore aimed at evaluating the applicability of an empirical band ratio algorithm for estimating chromophoric dissolved organic matter (CDOM; a proxy for DOC) from the easily accessible satellite images Landsat TM-5, to counter the inaccessibility of the region in general.

  3. 18. Calculation of past and present water availability in the Mediterranean Region and future estimates according to the Thornthwaite water-balance model

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Cansu Karsili; [2013]
    Keywords : Physical Geography and ecosystem analysis; climate change; water balance; Thornthwaite; Mediterranean; modelling; GIS.; Earth and Environmental Sciences;

    Abstract : The Mediterranean region is one of the most sensitive regions in the world in the face of climate change. Many studies name this region as a “hot spot”. It is essential to model the water balance of this region in order to better understand the impacts of climate change. READ MORE

  4. 19. Mapping Lupinus nootkatensis in Iceland using SPOT 5 images

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Arna Björk Thorsteinsdottir; [2011]
    Keywords : alien invasive species; physical geography; remote sensing; unsupervised classification; maximum likelihood classification; geography; Earth and Environmental Sciences;

    Abstract : Frön och rötter från Lupinus nootkatensis infördes till Island år 1945 med syftet att undersöka artens potential att bidra till återställandet av eroderad mark. Arten, som ursprungligen kommer från Alaska, visade sig vara mycket effektiv i samband med detta och dessutom kostnadseffektiv. READ MORE
