Seismic-reflection surveys of the Chesapeake Bay, combined with geologic 

 mapping and analysis of boreholes on the Delmarva Peninsula, provide evidence 

 of at least three generations of the Susquehanna River system and three 

 generations of the Chesapeake Bay. The evidence for ancient courses of the 

 Susquehanna River is preserved as three distance paleochannels , and evidence 

 for ancient versions of the Chesapeake Bay is preserved as three sets of 

 paleochannel fill beneath the bay and three generations of barrier-spit 

 deposits on the southern Delmarva Peninsula. A history of three major marine 

 transgressions is recorded in the stratigraphy preserved in the filled 

 paleochannels and in the overlying barrier-spit complexes: three systematic 

 progressions from fluvial to estuarine to bay or nearshore marine 

 environments. The three paleochannel-f ill and barrier-spit complexes appear 

 to corresponds to oxygen- isotope stages 1, 5, and either 7 or 11; the three 

 related paleochannels correspond to stages 2, 6, and either 8 or 12.

Radiocarbon dating of marsh peats in south-central Louisiana permits 

 interpretations of relationships between former positions of land and sea. 

 Past marsh surfaces, now buried at depths ranging from 4 to 40 ft, indicate 

 the positive change in level that has taken place since their origin. 

 Abundant evidence for a stillstand in sea- level during the past 

 2000-5000 years affords a fixed datum for differentiation between eustatic 

 sea-level rise and subsidence in the study area is 0.24 ft per century. 

 Results show a eustatic sea- level was higher than at present at any time 

 during the interval studied. (Authors) .

 From the Quaternary of North and South Carolina, U.S. Atlantic Coast," 

 Ostracoda in the Earth Sciences , pp 77-88. 



Thirteen marginal marine ostracod species restricted to brackish water 

 lagoonal, estuarine and salt marsh habitats of the US Atlantic coast were used 

 for identifying palaeoshorelines and coastal environments. Marginal marine 

 ostracod species were analyzed from two Quaternary sections from North and 

 South Carolina for which reliable ages and palaeoclimatic data were available. 

 The results indicated a general faunal pattern for several middle and late
