locally represented by a submarine hardground that formed after drowning of a 

 carbonate shelf. In the updip Gulf Coast, mid-Cenomanian paraoki and deltaic 

 sediments were deposited upon an Albian-early Cenomanian shallow carbonate 

 shelf. In the downdip Gulf Coast, this event either is not recognizable in 

 deep-water muds or is represented by drowning of shallow-water carbonates. A 

 third, intra-Albian event at 104.3 Ma may also be a eustatic sea- level rise; 

 however, it needs to be identified in other tectonic settings. (Authors).

 Investigations on the Soviet Primorye Coast: Their Application to 

 Interpretations of Paleoclimates and Former Sea-Levels," Journal of Coastal 

 Research . Vol 1, No. 2, pp 141-149. 



Sixteen archeological sites along the coast of Soviet Primorye formed 

 the basis for developing geoarcheological methodologies. Stages and methods 

 of subsistence by ancient peoples are used to infer prior climatic conditions 

 and former sea- levels. Artifact-bearing sediments, geomorphological position, 

 and results of granulometric , mineralogical-petrographical , and spore-pollen 

 analyses as well as radiocarbon dates were studied for the sixteen 

 archeological sites. Three broad levels of cultural development were 

 identified the Vestigial Neolithic, Bronze Age, and Early Iron Age. Based on 

 three geoarcheological investigations, it was determined that sea- level rose 

 repeatedly to higher stands (compared to the present) during the Holocene. 

 Transgressions are thought to have occurred 3,000 year ago and again at about 

 2,000 BP. These high stands are tentatively identified with the Atlantic 

 period and also correspond with recognized relict shorelines along the 

 Japanese coast. The correlation between changes in sea- level and monsoon 

 climate in coastal Primorye is attributed to the Peterson- Shnitnikov mechanism 

 where a high monsoon index corresponds to a lowering of sea- level and a low 

 index to a rising sea- level. A possible exception occurred 2,000 years ago 

 when a transgression coincided with a high monsoon index. It was probably a 

 response to Holocene warming at this time. (Authors).

 System and Its Implication For Sea-Level History Reconstructions in 

 Southwestern Australia," Marine Geology . Vol 67, pp 197-212. 



The Leschenault Peninsula in southwestern Australia is a Holocene retro- 

 graded barrier dune system. The barrier separates an estuarine- lagoon from 

 the Indian Ocean and, in Holocene time, the barrier has migrated over 

 estuarine sediments deposited leeward of the dune system. Stratigraphic stud- 

 ies and radiocarbon dates indicate that the barrier has had a complex history 

 resulting in composite internal structure. The barrier is composed of three 

 members, each of which was emplaced during a discrete historical phase in the 

 Holocene when relative sealevel stood: (1) at 2 or 3 m below present level 

 between ca. 8,000-5,500 '"C years B.P.; (2) 3 or 4 m above present level about 

 ca. 4,800-3,000 '■'C years B.P.; and (3) at present level ca. 2,800 '"C years 

 B. P. -present . The fact that the barrier still exists as a structure even 

 though it has experienced such widely fluctuating sealevels indicates that
