  1. 16. Atmospheric & Oceanic Applications of Eulerian and Lagrangian Transport Modelling

    Author : Joakim Kjellsson; Kristofer Döös; Jonas Nycander; Joseph LaCasce; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Eulerian; Lagrangian; trajectory; climate; atmosphere; ocean; modelling; drifter; thermodynamic; climate change; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : This thesis presents several ways to understand transports of air and water masses in the atmosphere and ocean, and the transports of energy that they imply. It presents work using various kinds of observations as well as computer simulations of the atmosphere and oceans. READ MORE

  2. 17. Man, murres and modern fisheries : A case study in the Baltic Sea

    Author : Martina Kadin; Henrik Österblom; Olof Olsson; Carl Folke; Morten Frederiksen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seabirds; ecosystem dynamics; fisheries; indicators; ecosystem services; Baltic Sea; common murre; common guillemot; Uria aalge; naturresurshushållning; Natural Resources Management;

    Abstract : Overfishing and climate change put increasing pressure on marine systems, with effects on commercially targeted fish and top predators dependent on these resources. To achieve sustainable resource use, governance mechanisms need to incorporate knowledge about ecosystem dynamics. READ MORE

  3. 18. The Impact of Multiple Drivers on Marine Systems : Novel approaches for studying structural changes

    Author : Johanna Yletyinen; Thorsten Blenckner; Örjan Bodin; Erik Bonsdorff; Daniel Stouffer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; naturresurshushållning; Natural Resources Management;

    Abstract : Human action is transforming the species composition, biogeochemistry and habitats of the world’s oceans at unprecedented rates. The cumulative effect of natural and anthropogenic drivers is challenging to measure, in part due to indirect effects and the complexity of marine systems. READ MORE

  4. 19. Air-Sea Fluxes of CO2 : Analysis Methods and Impact on Carbon Budget

    Author : Maria Norman; Anna Rutgersson; Erik Sahlée; William Drennan; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; air-sea exchange; carbon dioxide; Baltic Sea; eddy-covariance method; inertial dissipation method; cospectral-peak method; Baltic Sea measurements; CO2 fluxes; Galathea 3 expedition; Baltic Sea modeling; water-side convection; coastal upwelling; carbon budget; Meteorology; Meteorologi;

    Abstract : Carbon dioxide (CO2) is an important greenhouse gas, and the atmospheric concentration of CO2 has increased by more than 100 ppm since prior to the industrial revolution.  The global oceans are considered an important sink of atmospheric CO2, since approximately one third of the anthropogenic emissions are absorbed by the oceans.

  5. 20. Microbial Metagenomics : A Tale of the Dead and the Living

    Author : Katarzyna Zaremba-Niedźwiedzka; Siv G.E. Andersson; Jeroen Raes; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; single-cell genomics; single cell; fossil metagenome; freshwater metagenome; LD12;

    Abstract : It is a microbial world we live in: microbes outnumber other organisms by several orders of magnitude, and they have great importance for the environment. However, environmental microbes are notoriously difficult to grow in the laboratory, and using culture independent techniques is necessary to expand our view. READ MORE
