Contaminated Sediment News Issue #27 - June 2002 | US EPA11-12-2009
Further analysis suggested that the mixed-layer depth is much more likely to be controlled by POC flux than biogenic mixing intensity, and that the mixed-layer depth is negatively related to oxygen penetration into the sediment ...
