  2. 1. Ecosystem services of wetlands and wetlandscapes under hydro-climatic change : Impacts of water flow and inundation patterns

    Author : Imenne Åhlén; Jerker Jarsjö; Peter Hambäck; Georgia Destouni; Andrew Frampton; Heather E. Golden; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Ecohydrology; Wetlands; Wetlandscapes; Ecosystem services; Spatial Ecology; naturgeografi; Physical Geography;

    Abstract : Wetlands provide ecosystem services valuable for human society and are therefore often considered as nature based solution to different environmental problems. However, with centuries of wetland degradation due to anthropogenic pressures, such as agricultural expansion and forest industry, as well as pressures from climate change, there are large challenges for sustainable wetland management.

  4. 2. Linking water and permafrost dynamics

    Author : Ylva Sjöberg; Steve Lyon; Andrew Frampton; Britta Sannel; Georgia Destouni; Michelle Walvoord; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; permafrost; hydrology; arctic; modeling; streamflow; geophysical measurements; ground thermal dynamics; groundwater; Physical Geography; naturgeografi;

    Abstract : The extent and dynamics of permafrost are tightly linked to the distribution and movement of water in arctic landscapes. As the Arctic warms more rapidly than the global average, profound changes are expected in both permafrost and hydrology; however, much is still not known about the interactions between these two systems.

  5. 3. Changes in the Freshwater System : Distinguishing Climate and Landscape Drivers

    Author : Fernando Jaramillo; Georgia Destouni; Zbigniew W. Kundzewicz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Budyko; evapotranspiration; freshwater; hydrology; hydroclimatic change; landscape change; land use; observation data; runoff; separation; water partitioning; water storage change; water use; worldwide; Physical Geography; naturgeografi;

    Abstract : Freshwater is a vital resource that circulates between the atmosphere, the land and the sea. Understanding and quantifying changes to the partitioning of precipitation into evapotranspiration, runoff and water storage change in the landscape are required for assessing changes to freshwater availability.

  6. 4. The layer that did not swim away : Broadband acoustic discrimination and characterization of ocean stratification

    Author : Elizabeth Reed-Weidner; Martin Jakobsson; Richard Hobbs; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acoustical Oceanography; acoustics; oceanography; stratification; remote sensing; maringeologi; Marine Geology;

    Abstract : Ocean stratification plays a critical role in many oceanographic processes. The magnitude of mixing between stable water masses is regulated, in part, by the intensity of stratification. READ MORE

  7. 5. Model analysis of ocean carbon storage and transport across climate states

    Author : Malin Ödalen; Jonas Nycander; Johan Nilsson; Kevin I. C. Oliver; Nathaelle Bouttes-Mauhourat; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Oceanography; Climate; Climate model; Carbon cycle; Paleoclimate; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : The ocean carbon cycle plays a fundamental role in the Earth’s climate system, on decadal to multi-millennial timescales. Of the carbon held in the ocean, the atmosphere, and the terrestrial biosphere combined, more than 90% resides in the ocean. Carbon enters the surface ocean through air-sea gas exchange and from terrestrial sources. READ MORE
