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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Abstract : 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. READ MORE

  3. 2. Thermal induced yellowing of peroxide bleached birch pulp

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Alexander Nygren; [2020]
    Keywords : Accelerated ageing; Bleaching; Brightness reversion; Kraft pulp; pH; Yellowing;

    Abstract : Brightness reversion, also known as yellowing, is a well-known phenomenon which means that the brightness of paper products decreases during ageing. The name of this phenomenon is based on that paper products usually change in color towards yellow during ageing. READ MORE

  4. 3. Photo-chemical reactivity of dissolved organic carbon in subarctic lakes from northern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Hani Younes; [2020]
    Keywords : Photo-reactivity; DOM; subarctic lakes; EEM-PARAFAC. Brownification; Earth and Environmental Sciences;

    Abstract : Dissolved organic matter (DOM) is the major absorber of sunlight in most natural waters and a critical component of the carbon cycle in aquatic systems. The photochemical decomposition of DOM can have a significant impact on the landscape-atmosphere carbon exchange. READ MORE

  5. 4. Can we use optical sensors in highly turbid agricultural streams?

    University essay from SLU/Dept. of Soil and Environment

    Author : Ana Paula Abade Smoginski; [2017]
    Keywords : optical sensors; phosphorus and sediment losses; turbidity; organic matter; agricultural catchments;

    Abstract : Optical sensors are advanced technology capable of monitoring water quality con-tinuously at high temporal resolution. Optical sensors are prone to errors when deployed in streams with high sediment content. Agricultural streams, with high and variable suspended sediment loads, can affect the performance of these instru-ments. READ MORE

  6. 5. 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.
