Ancient Channels Of The Susquehanna River Beneath Chesapeake Bay And The Delmarva Peninsula, Steven M. Colman, Jeffrey P. Halka, C. Hobbs, Robert B. Mixon, David S. Foster

VIMS Articles

Three generations of the ancestral Susquehanna River system have been mapped beneath Chesapeake Bay and the southern Delmarva Peninsula. Closely spaced seismic reflection profiles in the bay and boreholes in the bay and on the southern Delmarva Peninsula allow detailed reconstruction of each paleochannel system. The channel systems were formed during glacial low sea-level stands, and each contains a channel-fill sequence that records the subsequent transgression. The trunk channels of each system are 2 to 4 km wide and are incised 30 to SO m into underlying strata; they have irregular longitudinal profiles and very low gradients within the Chesapeake …

Pliocene And Pleistocene Depositional Environments On The York-James Peninsula, Virginia; A Field Guidebook, Gerald H. Johnson, Carl H. Hobbs Iii

Reports

The late Cenozoic deposits of southeastern Virginia represent a wide variety of depositional environments and record numerous marine transgressions. The formations range in age from Miocene to Holocene. This fieldguide provides an opportunity to visit and sample highly fossilferous marine bay and fluvial-estuarine sediments exposed in river bluffs and borrow pits on the York-James Peninsula.

Geological And Benthic Evaluation Of Sand Resources In The Lower Chesapeake Bay, Report 2, Tail Of The Horseshoe : Final Report V.1, Carl C. Hobbs Iii, Linda C. Schaffner

Reports

This is the second of two reports concerning the resources of sand in the lower portions of Chesapeake Bay. The first, Geotechnical and Benthic Evaluation of Sand Resources in the Lower Chesapeake Bay (Kimball and others, 1989), presents a study of the resources in Thimble Shoal. The present work is a study of the area known as Tail of the Horseshoe which is just east of Thimble Shoal (Figure 1). The deposits of sand described in this report will be of most interest to the communities of Norfolk and Virginia Beach.
