1. 1. Underwater Worlds : An Ethnography of Waste, Pollution, and Marine Life

   Författare :Rasmus Rodineliussen; Bengt Karlsson; Helena Wulff; Marianne Lien; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Aquabiopolitics; Lake Mälaren; Marine Life; Pollution; Relations; Science; Social Media; Stockholm; The Baltic Sea; Time; Trash Diving; Violence; Visibility; Waste; Water; Social Anthropology; socialantropologi;

   Sammanfattning : In this dissertation, I investigate relations between humans, waste, pollution, and marine life. I introduce the concept of Aquabiopolitics as a means to understand how humans govern life in water in order to enrich human life on land. LÄS MER

3. 2. Genetic Aspects of Environmental Disturbances in Marine Ecosystems : Studies of the Blue Mussel in the Baltic Sea

   Författare :Josefine Larsson; Mats Grahn; Inger Porsch-Hällström; Katarzyna Smolarz; Andrew Whitehead; Södertörns högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Blue mussel; Baltic Sea; anthropogenic disturbance; pollution; sewage effluents; harbors; genetics; genomics; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

   Sammanfattning : Anthropogenic environmental changes can serve as drivers for evolutionary responses in wild populations. To predict the long-term impact of anthropogenic changes on populations, it is crucial to understand the genetic effects caused by these disturbances. LÄS MER

4. 3. Coral reefs in the Anthropocene : The effects of stress on coral metabolism and symbiont composition

   Författare :Suzanne Faxneld; Michael Tedengren; Alina Szmant; Stockholms universitet; []
   Nyckelord :Corals; Disturbance; Galaxea fascicularis; ITS2; Metabolism; mtDNA; Pollution; Porites lutea; Symbiodinium; Temperature; Turbinaria mesenterina; Vietnam; Marine Ecotoxicology; marin ekotoxikologi;

   Sammanfattning : Coral reefs constitute some of the most prolific and diverse ecosystems on our planet, but also among the most threatened. This thesis investigates the effects of environmental stressors on corals’ metabolism and symbiont diversity. LÄS MER

5. 4. Element transport in marine coastal ecosystems – modelling general and element-specific mechanisms

   Författare :Lena Konovalenko; Clare Bradshaw; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Modelling; bioaccumulation; concentration ratio; radionuclides; marine foodweb.; Marine Ecology; marin ekologi;

   Sammanfattning : Understanding the behaviour of naturally-occurring and anthropogenically-derived radionuclides (isotopes) in the marine environment is important, because there is a need for their effective utilization either as in situ tracers or for industry, medical applications, the planning of waste-disposal facilities, and estimations of human and animal health risks. Radionuclides generally have the same chemical properties as their stable element analogues and thus show similar environmental behaviour and cycling to their stable counterparts. LÄS MER

7. 5. Life Cycle Assessment of Present and Future Marine Fuels

   Författare :Selma Bengtsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA; marine fuels; environmental impact; LNG; biofuels; heavy fuel oil; Life Cycle Assessment; marine gas oil; liquefied natural gas;

   Sammanfattning : Interest in new fuels for marine propulsion is growing, mainly as a result of stricter environmental regulations but also due to increased attention to air pollution, greenhouse gas emissions and the uncertainty of future oil supply. Several different fuels and exhaust abatement technologies are proposed for marine transportation, all of which have different advantages and disadvantages in relation to the environment and human health.
