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

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

    Sammanfattning : 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. LÄS MER

  3. 42. Towards an understanding of diazocyte development and diazotrophy in the marine cyanobacterium Trichodesmium

    Författare :Gustaf Sandh; Birgitta Bergman; Rehab El-Shehawy; Louis Sherman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; Trichodesmium; diazocyte; cell differentiation; nitrogen fixation; cell division; flavodoxin; Plant physiology; Växtfysiologi; Plant Physiology; växtfysiologi;

    Sammanfattning : Trichodesmium is a filamentous cyanobacterium of great ecological significance as it contributes significantly to primary production in oceans through an efficient nitrogen fixation strategy, including a unique cell type, the diazocyte. The aim of this thesis was to generate a deeper understanding of the structural and molecular background related to the development of diazocytes and the maintenance of diazotrophy in Trichodesmium erythraeum IMS101.

  4. 43. Blurring the Colonial Binary : Turn-of-the-Century Transnational Entertainment in Southeast Asia

    Författare :Nadi Tofighian; John Fullerton; Charles Musser; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; colonial history; early cinema; film history; distribution; transnational networks; entertainment culture; Southeast Asia; Singapore; postcolonial theory; colonial discourse; ethnicity; race; whiteness; Cinema Studies; filmvetenskap;

    Sammanfattning : This dissertation examines and writes the early history of distribution and exhibition of moving images in Southeast Asia by observing the intersection of transnational itinerant entertainment and colonialism. It is a cultural history of turn-of-the-century Southeast Asia, and focuses on the movement of films, people, and amusements across oceans and national borders. LÄS MER

  5. 44. Multiple forces drive the Baltic Sea food web dynamics and its response to environmental change

    Författare :Susa Niiranen; Thorsten Blenckner; Olle Hjerne; Mike Elliott; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; climate change; Ecopath with Ecosim; food web interactions; multiple drivers; regime shift; trophic control; Marine Ecology; marin ekologi;

    Sammanfattning : Understanding the interaction of multiple drivers and their compounded effects on ecosystem dynamics is a key challenge for marine resource management. The Baltic Sea is one of the world’s seas most strongly impacted by effects from both human activities and climate. LÄS MER

  7. 45. Sea water – shelf sediment interactions: Tracing Neodymium export and water/particle exchange with radiogenic isotopes

    Författare :Per-Olov Persson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Ocean circulation is a key component for the Earth climate system. Driven by wind and density distribution, governed by temperature and salinity, the ocean currents are redistributing heat from low to high latitudes. LÄS MER
