Paleodeltas and Preservation Potential on a Paraglacial Coast — Evolution of Eastern Penobscot Bay, Maine

Sea-level change and inner shelf stratigraphy off Northern Ireland

“…The unconformity clearly truncates acoustic reflectors in the glacial-marine material and marks the post-lowstand rise in sea level. Similar interpretations were recognized elsewhere (Barnhardt et al, 1997;Kelley et al, 1992;Belknap et al, 2004;Stea et al, 1994). We interpret the sand deposits near the 30 m isobath in the two deeper cores as low-energy beach deposits slightly seaward of an eroding bluff of glacial-marine mud.…”

Subsurface Evidence of Storm-Driven Breaching along a Transgressing Barrier System, Cape Cod, U.S.A.

“…They allow for the development of safe harbors (Turner et al, 1998), nursery grounds for commercially important fish species, and areas for recreation (Barbier et al, 2011). In New England, most coastal barriers were formed during the past 5000 years and derived their sediments from the transgressive reworking of glacial and fluvial deposits (Belknap, Gontz, and Kelley, 2005;FitzGerald, Buynevich, and Rosen, 2001; Uchupi and Mulligan, 2006;van Heteren et al, 1998). The continued rise in sea level coupled with a coeval reduction in sediment supply make retrograding barriers a relatively common landform along the formally glaciated coastline of Massachusetts (FitzGerald, Buynevich, and Rosen, 2001;Gutierrez et al, 2003).…”

Glaciated Coasts

“…Although fjords and other overdeepened basins and glaciated or progla cial shelves are important sinks for proglacial and paraglacial sediments, the focus in this chapter is on specifically coastal settings in a range of embayments (including fjords) and open coastal environments. The widespread Holocene marine trans gression, which continues today in many areas marginal to former continental ice sheets, has resulted in the partial pre servation of paraglacial coastal facies on adjacent continental shelves (e.g., Belknap et al, 1994Belknap et al, , 2002Belknap et al, , 2005Forbes et al, 1993Forbes et al, , 1995b.…”
