Shifts in coastal sediment oxygenation cause pronounced changes in microbial community composition and associated metabolism
Background A key characteristic of eutrophication in coastal seas is the expansion of
hypoxic bottom waters, often referred to as 'dead zones'. One proposed remediation strategy …
