Engineered aeration is one solution for increasing oxygen concentrations in highly eutrophic estuaries that undergo seasonal hypoxia. Although there are various designs for engineered aeration, all approaches involve either destratification of the wa

Biogeochemical processes capable of altering global carbon systems occur frequently in Earth’s Critical Zone–the area spanning from vegetation canopy to saturated bedrock–yet many of these phenomena are difficult to detect. Observation of these

Permafrost sediments contain one of the largest reservoirs of organic carbon on Earth that is relatively stable when it remains frozen. As air temperatures increase, the shallow permafrost thaws which allows this organic matter to be converted into p

Weathered crude oil sank to the seafloor following the 'Deepwater Horizon' disaster in 2010, removing this oil from further physical and photo-chemical degradation processes and leaving benthic processes as the mechanisms for altering and remediating

Current estimates of methane (CH 4 ) flux suggest that Arctic shelves may be a significant source of atmospheric CH 4 , a potent greenhouse gas. However, little information is known about the CH 4 flux from most Arctic shelves, other than the East Si
