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 AE 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.
