  1. 1. Snow and sea ice temperature profiles from satellite data and ice mass balance buoys

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Isabella Grönfeldt; [2016]
    Keywords : IMB; ice mass balance buoys; snow-ice interface; air-snow interface; temperature profile; snow; sea ice; Fram Strait; Greenland; Arctic Ocean; climate change; climate; physical geography and ecosystem analysis; remote sensing; satellite; sensor; SMOS; AMSR-2; TIR; numerical weather prediction; multiple regression analysis; Earth and Environmental Sciences;

    Abstract : The sea ice covers approximately 5% of the Earth’s surface at any given time and it plays an important role in the polar climate system affecting the heat, mass and momentum exchange between the atmosphere and the ocean. The snow cover on top of the sea ice affects its insulating and reflective properties and thus key figures in the climate system feedback loop. READ MORE

  2. 2. Is there an influence of solar activity on the North Atlantic Oscillation? : a literature study of the forcing factors behind the North Atlantic Oscillation

    University essay from Lunds universitet/Geologiska institutionen

    Author : Ida Johansson; [2015]
    Keywords : stratospheric-tropospheric couplings; solar activiy; The North Atlantic Oscillation; blockings; climatic variations; Earth and Environmental Sciences;

    Abstract : Nordatlantiska Oscillationen (NAO) är ett atmosfäriskt cirkulationsfenomen som kännetecknas av skillnader i havsnivåtryck mellan högtrycksområdet vid Azorerna och lågtrycksområdet över Island. NAO varierar mellan en positiv och negativ fas beroende på hur väl utvecklade dessa högtrycksområden är. READ MORE

  3. 3. Shipping in the World's Northernmost Ocean - Legal Disputes & Controversies in the Arctic Sea Routes & the Legal Impact of an Future Internationalization

    University essay from Lunds universitet/Juridiska institutionen

    Author : Daniel Jonsson; [2014]
    Keywords : Transpolar Sea Route; Northwest Passage; Northern Sea Route; Arctic; Article 234; Daniel Jonsson; Daniel Viktor Jonsson; Law and Political Science;

    Abstract : Arktis utgör ett av de minst utvecklade internationella regioner i världen. Trots politiska initiativ som arktiska rådet och liknande existerar det inte idag något övergripande legalt ramverk för att adressera flertalet juridiska dispyter och kontroverser. READ MORE

  4. 4. Unsupervised Change Detection Using Multi-Temporal SAR Data : A Case Study of Arctic Sea Ice

    University essay from KTH/Geodesi och geoinformatik

    Author : Linda Fröjse; [2014]
    Keywords : sea ice; the Arctic; Kittler-Illingworth; generalized Gaussian distribution; log-normal distribution; ERS; ENVISAT; SAR; ASAR; havsis; Arktis; Kittler-Illingworth; generaliserad normaldistribution; lognormal distribtion; ERS; ENVISAT; SAR; ASAR;

    Abstract : The extent of Arctic sea ice has decreased over the years and the importance of sea ice monitoring is expected to increase. Remote sensing change detection compares images acquired over the same geographic area at different times in order to identify changes that might have occurred in the area of interest. READ MORE

  5. 5. On the Relation Between Arctic Sea Ice and European Cold Winters During the Little Ice Age 1400-1850

    Keywords : Barents Sea; Kara Sea; sea ice reduction; Arctic; midlatitudes; feedback effect; Last Millennium; historical climate change; climate modeling; threshold; global warming; cold winters; Little Ice Age; North Atlantic oscillation; LIA; NAO; PMIP3; CMIP5; NASA-GISS.; Barents hav; Karahavet; reducerat istäcke; Arktis; mellanbredderna; återkopplingseffekt; historiska klimatförändringar; klimatmodellering; tröskeleffekt; global uppvärmning; kalla vintrar; Lilla istiden ; Nordatlantiska oscillationen; NAO; PMIP3; CMIP5; NASA-GISS.;

    Abstract : This study aims to investigate the possible historical correlation between sea ice reduction in the Arctic and cold winters in Central Europe. The study is conducted over a cold period in Europe known as the Little Ice Age (LIA), 1400–1850, and uses a Global Climate Model with eight different forcing scenarios. READ MORE
