“…availability of aerial photographs and satellite imagery, identification and investigation of aeolian sand deposits in the unglaciated eastern USA increased (e.g., Hack, 1955;Hurst et al, 1966a,b;Daniels et al, 1969;Thom, 1970;Otvos, 1971;Pickering and Jones, 1974;Saucier, 1977;Thames, 1982). Continued advancements in radiocarbon, luminescence, and isotopic dating techniques, as well as increased availability of remotely-sensed imagery and high datadensity digital elevation datasets facilitated more-recent geologic, geochronologic, archaeologic, and paleoclimatic investigations of these deposits (Carver and Brook, 1989;Markewich and Markewich, 1994;Leigh and Ivester, 1998;Brooks et al, 2001Brooks et al, , 2010Ivester et al, 2001Ivester et al, , 2002Ivester et al, , 2004aIvester et al, ,b, 2007Ivester et al, , 2009Otvos and Price, 2001;Ivester and Leigh, 2003;Otvos, 2004;Wagner and McAvoy, 2004;Feathers et al, 2006;Markewich et al, 2009aMarkewich et al, ,b, 2010bMarkewich et al, , 2011aMarkewich et al, , 2012Markewich et al, , 2013Lowery et al, 2010;Pavich et al, 2010;Wysocki et al, 2010;Moore and Brooks, 2011;Moore and Daniel, 2011;Swezey et al, 2013;Moore et al, 2014).…”

“…Ivester et al (2004) used this dating method to establish the multiple phases of bay evolution during the past 100,000 years. Brooks et al (2010) concluded that most of the bays formed during the late Pleistocene, and Frey (1954) and Thom (1970) provided evidence for recent enlargement of existing bays. Moore et al (2014) demonstrated geomorphologically and stratigraphically that these bays migrate through their own lacustrine deposits and calculated the migration rate from a series of OSL dates.…”

A study of soil gases was made in North Carolina (USA) in and around morphological depressions called "Carolina bays." This type of depression is observed over the Atlantic coastal plains of the USA, but their origin remains debated. Significant concentrations of molecular hydrogen (H 2 ) were detected, notably around the bays. These measurements suggest that Carolina bays are the surficial expression of fluid flow pathways for hydrogen gas moving from depth to the surface. The potential mechanisms of H 2 production and transport and the geological controls on the fluid migration pathways are discussed, with reference to the hypothesis that Carolina bays are the result of local collapses caused by the alteration of rock along the deep pathways of H 2 migrating towards the surface. The present H 2 seepages are comparable to those in similar structures previously observed in the East European craton.

“…The Carolina Bays are thousands of shallow elliptical depressions with elevated rims scattered along the Atlantic Coastal Plain (see Brooks et al , ), which formed asynchronously over a significant period with multiple periods of rim accretion with intervening periods of erosion (Grant et al , ; Rodriguez et al , ).

During the end of the last glacial period in the Northern Hemisphere near 12.9k cal a BP, deglacial warming of the Bølling–Ållerod interstadial ceased abruptly and the climate returned to glacial conditions for an interval of about 1300 years known as the Younger Dryas stadial. The Younger Dryas Impact Hypothesis proposes that the onset of the Younger Dryas climate reversal, Pleistocene megafaunal extinctions and disappearance of the Clovis paleoindian lithic technology were coeval and caused by continent‐wide catastrophic effects of impact/bolide events in North America. While there are no known impact structures dated to the Younger Dryas onset, physical evidence of the impact/bolide events is argued to be present in sediments spanning several continents at stratigraphic levels inferred to date to the Bølling‐Ållerod/Younger Dryas boundary (YDB). Reports of nanometer to submicron‐sized diamonds in YDB sediments, in particular the rare 2H hexagonal polytype of diamond, lonsdaleite, have been presented as strong evidence for shock processing of crustal materials. We review the available data on diamonds in sediments and provide new data. We find no evidence for lonsdaleite in YDB sediments and find no evidence of a spike in nanodiamond concentration at the YDB layer to support the impact hypothesis.
