  1. 16. Transport av förorenat sediment i Eskilstunaån

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Frida Gällstedt; [2019]
    Nyckelord :sediment transport; contaminated sediment; modelling; HEC-RAS; ArcGIS; accumulation; erosion; sedimenttransport; förorenat sediment; modellering; HEC-RAS; ArcGIS; ackumulationsbotten; erosionsbotten;

    Sammanfattning : Eskilstuna har sedan länge varit en industristad vilket har inneburit utsläpp av främst metallföroreningar men även organiska ämnen till Eskilstunaån. Provtagningar har vid upprepade tillfällen gjorts och det har visats att sedimentet i ån innehåller höga halter av förorenande ämnen. LÄS MER

  3. 17. Öreland- en försvunnen värld

    Kandidat-uppsats, Lunds universitet/Arkeologi

    Författare :Ingela Schånberg; [2019]
    Nyckelord :Late Paleolithic; Early Mesolithic; inundated areas; Öresund; Öreland; land bridge; settlements; bathymetry; History and Archaeology;

    Sammanfattning : Öreland – a Lost World The aim of this BA Study is two-folded. First, to investigate if and when the Strait of Öresund has been dry land and, second, if there are traces of human activities – tools and settlements – that could be related to Öreland, e.g. when Öresund was dry land.

  4. 18. Machine Learning for Inferring Sidescan Images from Bathymetry and AUV Pose

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Zitao Zhang; [2019]
    Nyckelord :;

    Sammanfattning : Underwater navigation has been a big challenge for autonomous underwater vehicles (AUVs) for a long time. It is highly dependent on acoustic methods called SONAR. There are two kinds of sonar sensors which are commonly used, the multibeam sonar and the sidescan sonar. Both of them have some advantages and limitations. LÄS MER

  5. 19. Humpback whale (Megaptera novaeangliae) location in Southeast Alaska : modeling the influence of mesoscale krill (Euphausiacea) patch depth and size

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Christine Walder; [2018]
    Nyckelord :physical geography and ecosystem analysis; humpback whales; krill; patchiness; vertical distribution; Generalized Additive Models GAMs ; spatial modeling; Earth and Environmental Sciences;

    Sammanfattning : Humpback whales ([i]Megaptera novaeangliae[/i]) require dense prey aggregations due to the high energetic cost of their feeding methods. Modeling studies have shown that when whales are on their feeding grounds, they are closely associated with high prey concentrations. LÄS MER

  7. 20. Sediment transport and bathymetric change at Hornafjörður tidal inlet - Field data analysis and mathematical modeling

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Clemens Klante; [2018]
    Nyckelord :Coastal Inlet; Hornafjörður; Morphology; TELEMAC; ebb shoal; mathematical modeling; Technology and Engineering;

    Sammanfattning : Commercial fishing makes the coastal inlet in Hornafjörður to an important navigational link for the port of Höfn in southeast Iceland. Low water depth caused through sediment accumulation along the ebb shoal generates navigational problems and the phenomenon of glacial rebound seems to intensify this problem. LÄS MER
