Abstract : Foraminiferal proxies of hypoxia indicate apparent low oxygen to hypoxic conditions in several hotspots in the Mississippi Bight. The foraminiferal hypoxia proxies, the Ammonia to Ephidium (A/E) index and the Pseudononion- Epistominella- Bullimella (PEB) index were tabulated from three sets of core tops collected in 1951-1956. Additionally, the oxygenation history of a site near the Balize delta was evaluated over the past one hundred years based on ArE and PEB indices and size distributions of pyrite framboids in a gravity core dated by 210Pb geochronology.
