1. Fate and transport of POPs in the aquatic environment : with focus on contaminated sediments
Abstract : Persistent organic pollutants (POPs) are hydrophobic substances that readily sorb to organic matter in particles and colloids instead of being freely dissolved in the water phase. This sorption affects the bioavailability and environmental transport of the POPs. READ MORE

2. Microbially induced concrete degradation in subsea tunnels - Community structure of biofilms from sprayed reinforced concrete in the Oslofjord tunnel
Abstract : Microbially induced concrete deterioration has been discovered in several Norwegian subsea tunnels with significant disintegration of the calcium silicate hydrate (C-S-H) and steel fibre corrosion in areas with leakages of saline groundwater. Complex microbial biofilm activity together with abiotic attack from saline ground water, with high concentrations of Cl−, SO42−, Mg2+ and HCO3−, are responsible for the degradation in the specific subsea tunnel environment.

3. Nutrient Dynamics and Exchanges Between a Mangrove Forest and a Coastal Embayment: Chwaka Bay, Zanzibar
Abstract : Nutrient dynamics and exchanges were studied in the Mapopwe Creek, a tidally dominated mangrove lined waterway, and a shallow lagoon in Chwaka Bay, Zanzibar, in order to assess whether there was any ecological coupling between the mangrove forest and adjacent ecosystems. In this study it was found that seasonal terrestrial input sources and benthic microalgal uptake strongly influenced the concentrations and distribution of dissolved nutrients in the system.

4. Mechanisms of below-ground carbon cycling in subarctic ecosystems
Abstract : Some components of the below-ground carbon (C) cycle in terrestrial ecosystems are still poorly understood. A better understanding will be necessary to predict adequately the impacts of global change factors on C cycling and storage, especially in high-latitude ecosystems, where much of the C is stored below-ground.

5. Ecology across Boundaries : Food web coupling among and within ecosystems
Abstract : Cross-boundary movements of energy and material are ubiquitous. Freshwater ecosystems receive nutrients, dissolved, and particulate organic matter from adjacent terrestrial ecosystems, whereas terrestrial ecosystems mainly receive prey organisms and detritus deposited by physical processes such as floods from freshwater ecosystems.
