Normally atmospheric CO2 is the major driver of ocean acidification (OA); however, local discharge/degradation of organic matter (OM) and redox reactions can exacerbate OA in coastal areas. In this work we study the response of nutrient and carbon system...

The mobility of a metal in mining-impacted sediments is determined by the environmental conditions that influence the metal?s oxidation state and bonding environment. Coeur d?Alene Lake, USA, has been impacted by legacy mining practices that allowed the ...

For infrastructure applications in marine environments, the eventual initiation of corrosion (and pitting) of steels (and other metals and alloys) often is assumed an inescapable fact, and practical interest then centres on the rate at which corrosion da...
