  1. 11. Analys av metanflöden från sjön Erken

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

    Author : Ryan Mintz; [2016]
    Keywords : methane; transfer velocity; flux; waterside concentration; eddy covariance; Nyckelord: metan; utbyteskoefficient; flux; metankoncentration; eddy kovarians;

    Abstract : While it is not the most abundant greenhouse gas, a significant portion of the greenhouse effect is caused by methane. The amount of methane in the atmosphere is increasing, indicating that there is a continuous source of methane to the atmosphere. READ MORE

  3. 12. An Investigation of the Relation between Sea Breeze Circulation and Diurnal Variation of Methane at a Swedish Lake

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

    Author : Martin Svensson; [2015]
    Keywords : WRF model; Sea breeze; methane emission; diurnal variation; internal boundary layer; WRF-modellen; sjöbris; metanemission; dygnsvariation; internt gränsskikt;

    Abstract : Methane measurements over lake Tämnaren show a pronounced diurnal variation with high values at night and low values during daytime. The atmosphere over the lake and its surroundings is simulated with two different settings and resolutions of the WRF model during a period of eight days in May 2011 to investigate if a lake/land breeze circulation could be the cause of the observed methane variation.

  5. 14. Paleoenvironment and shore displacement since 3200 BC in the central part of the  Långhundraleden Trail, SE Uppland

    University essay from Institutionen för naturgeografi och kvartärgeologi (INK)

    Author : Christos Katrantsiotis; [2013]
    Keywords : Shore displacement; isostatic variability; Uppland; saddle-point; paleoenvironment;

    Abstract : In this study, litho-, bio- and chronostratigraphic investigations combined with RTK GPSleveling have been carried out to reconstruct the paleoenvironment in the central part of theLånghundraleden Trail. The area displays four shallow lake basins of varyingmorphologies. The basins are now covered with peat as a result of infilling and overgrowth. READ MORE
