Harmful Algal Blooms and Their Assessment Fjords and Coastal Embayments
2015/7/27
Coastal embayments are a broad category of an ecosystem type that may be loosely defined as an enclosed or semi-enclosed aquatic environment along a land-mass margin. Embayments are highly diverse, re...
Risk Assessment and Ecotoxicology:Limitations and Recommendations for Ocean Disposal of Mine Waste in the Coral Triangle
Risk Assessment Ecotoxicology:Ocean Disposal Mine Waste Coral Triangle
2015/7/15
Mining is an important contribution to the economy of many developing tropical regions. Many sites of mining interest in the tropics have island geographies and potentially limited land area. While th...
Seabed foraging by Antarctic krill: Implications for stock assessment, bentho-pelagic coupling, and the vertical transfer of iron
Seabed foraging by Antarctic krill Implications for stock assessment bentho-pelagic coupling the vertical transfer of iron
2014/4/8
A compilation of more than 30 studies shows that adult Antarctic krill (Euphausia superba) may frequent benthic habitats year-round, in shelf as well as oceanic waters and throughout their circumpolar...
Living at the border: A community and single-cell assessment of lake bacterioneuston activity
Living at the border A community single-cell assessment lake bacterioneuston activity
2014/4/17
We assessed the physicochemical properties of the surface microlayer (SML: first 900mm) and its underlying water (ULW: 0.2–0.5-m depth) and compared the composition and activity of their bacterial com...
