The Ainsdale sand dunes have been designated as a national nature reserve and a Ramsar site. |
|
Coastal dunes expand laterally as a result of lateral growth of coastal plants via seed or rhizome. |
|
Additionally the height of coastal dunes is impacted by storm events, which can erode dunes. |
|
The grasses add nitrogen to the soil, meaning other, less hardy plants can then colonize the dunes. |
|
Young dunes are called yellow dunes and dunes which have high humus content are called grey dunes. |
|
Leaching occurs on the dunes, washing humus into the slacks, and the slacks may be much more developed than the exposed tops of the dunes. |
|
These dunes most often form as a continuous 'train' of dunes, showing remarkable similarity in wavelength and height. |
|
Sand dunes can have a negative impact on humans when they encroach on human habitats. |
|
Sand dunes move via a few different means, all of them helped along by wind. |
|
One way that dunes can move is by saltation, where sand particles skip along the ground like a bouncing ball. |
|
The gypsum sand dunes of the White Sands National Monument in New Mexico are famous for their bright, white color. |
|
Desert sand dunes and loess are examples of aeolian transport and deposition. |
|
Pinnipeds may move further inland and rest in sand dunes or vegetation, and may even climb cliffs. |
|
Some evidence of neolithic inhabitants has been found in the island's sand dunes, though its name is likely of Norse origin. |
|
|
North of Earnsie Point are secluded beaches, backed by dunes, which tend to be used by naturists. |
|
The oolites are commonly found in large current bedding structures that resemble sand dunes. |
|
The site is severely threatened by the rapid erosion of the overlying sand dunes. |
|
Sand dunes were much more widespread and active in many areas during the early Quaternary period. |
|
Compound dunes are large dunes on which smaller dunes of similar type and slipface orientation are superimposed, and complex dunes are combinations of two or more dune types. |
|
The sand mass of dunes can move either windward or leeward, depending on if the wind is making contact with the dune from below or above its apogee. |
|
The landscape has been formed for a great part by storm tides in the 10th to 14th centuries, overflowing and carrying away former peat land behind the coastal dunes. |
|
Models of coastal dunes suggest that their final equilibrium height is related to the distance between the water line and where vegetation can grow. |
|
Drenching sand dunes with oil stops their migration, but this approach is quite destructive to the dunes' animal habitats and uses a valuable resource. |
|
Recent work has suggested that coastal dunes tend to evolve toward a high or low morphology depending on the growth rate of dunes relative to storm frequency. |
|
The stability of the dunes was once attributed to the vegetative cover but recent research has pointed to water as the main source of parabolic dune stability. |
|
Planting dunes with vegetation also helps to stabilise them. |
|
The coastal plain consists mainly of sand dunes and polders. |
|
The body of rock, or facies, is dominated by alluvial sediments and conglomerates at its base, and progresses to a combination of dunes, lakes and river sediments. |
|
The site was farther from the sea than it is today, and it is possible that Skara Brae was built adjacent to a fresh water lagoon protected by dunes. |
|
With air suspension raised to boost ground clearance and plenty of urge to keep up momentum the Range Rover dusts across the dunes like a sand fly. |
|
Mycorrhizae and succession in plantings of beachgrass in sand dunes. |
|
Golf is a Scottish import to many countries but it is said to have been played in this region by St Cuthbert on the dunes of the Northumberland coast. |
|
Dome dunes are rare and occur at the far upwind margins of sand seas. |
|
And following that was a tortuous passage through a weird region of clay dunes, blue and violet and heliotrope and lavender, all worn smooth by rain and wind. |
