...TROY L PÉWÉ; RICHARD E CHURCH Abstract Three pieces of driftwood in frozen beach gravel were recovered at 77 inches, 115 inches, and 131 inches below the surface of the spit at Barrow, Alaska. Radiocarbon dating gives an age of 1100 ± 120 years for the stratigraphically highest wood fragment, 1090...

It extends from the town of Boundary Bay to approxi- mately 3 mi north of Beach Grove where the salt marsh begins (Fig . 3) . It occurs primarily on the beach face and extends seaward...

... of the multidisciplinary Kuril Biocomplexity Project. The Kurils are a volcanically active arc with many small islands in the central region ( Fig. 1 ). Accordingly, dominant coastal geomorphologies are rocky cliffs or boulder to gravel beaches, with some sandy embayments. Figure 1. A: Historical tsunamigenic...

A large fan of boulders transported during periods of flood is found at the river mouth and this gives an indication of the former width of the estuary. A conspicuous hill, situated on the coast about 3 miles north of Callo, forms...

... continuity can be used to constrain sea-level history. On Sandy Neck, a 10-km-long coastal spit, the boundary between dune sand and underlying beach sand and gravel forms a remarkably smooth plane, as reconstructed from bailer-auger cores and ground-penetrating-radar records ( van Heteren and van de...

During this study Violet Point, a gravel spit extending to the southeast, supported a breeding colony of 2000–3000 pairs of glaucous-winged gulls ( Cowles et al. 2012 ). We focused on nests built on the north beach of a small marina. Depending on the nature and duration...

... (~0.4 m) at 0.6 m downcore (Fig. 8 ). This coincides with an abrupt lithological contact between a woody, pebble gravel and overlying massive sandy mud. The gravel is similar in composition to that of extreme high tidal beaches today where driftwood is stranded. One piece of wood in the gravel has been...

... of a lagoon. Organic-rich deposits on the lakeward side of the lagoon were buried 9.3–9.4 ka by sand and gravel of the spit, and a thin overwash of sand marks this event throughout the lagoon. At about this time, Lake Agassiz fell below the Upper Campbell beach level. Subsequent accumulation at Wampum...

..., gravel is concentrated by wave processes on the barrier beach and in the surf zone, and much of this material is progressively reworked landward as the barrier migrates through overwash processes ( Reinson, 1992 ; Hart and Plint, 1995 ). Storms may transport some gravel down the shoreface...

... ). The foreshore is predominantly sand and pebble beach material, often littered with driftwood storm deposits ( Forbes and Frobel 1985 ; Harper et al. 1988 ). Beach berms and washover deposits indicate active storm remobilization and deposition. The majority of the beach material fronts low tundra cliffs...

... by the longshore currents diverging from the delta tip. Between the coastline inflection east of Lagos and the Benin River, however, the shore is muddy on account of the little sand so far drifted there. Nonetheless, the frequent occurrence of gravels of cohesive silt and clay debris shows this sector of the beach...

The periodic incorporation of coarse material may result in the observed patchy distribution found...

Crusts cover fluvial deposits in horizontal layers and finer shore and lacustrine sediments in wavy surfaces. The crusts appear also as fine laminae...
