by shipboard observations collected over the last 100 years. The ocean surface has highs and lows, similar to the hills and valleys of Earth s land surface depicted on a topographic map . These variations, called ocean surfacetopography or dynamic seasurfacetopography are mapped using measurements of seasurface height relative to Earth s geoid . Earth s geoid is a calculated surface of equal gravitational potential energy and represents the shape the seasurface would be if the ocean were not in motion.

Since the Earth s gravitational field is relatively stable on decadal to centennial timescales, ocean circulation plays a more significant role in the observed variation of SSH. Across the season seasonal cycle changes in patterns of warming, cooling and surface wind forcing affect circulation and influence SSH. Variations in SSH can be measured by satellite altimeter altimetry e.g. TOPEX Poseidon and used to calculate determine sea level rise and properties such as ocean heat storage.

Other uses Deadwater disambiguation Deadwater A deadwater is that part of an estuary through which there is little to no water flow. In situations where a river flow is weaker than the marine processes that build sand dune s, the river may be obstructed from flowing into the sea by the formation of a sand dune that is, a sandbar . In such cases the river will often form an elongate estuary in the swales of the dune. When river flow increases, or once the estuary has built up a large mass of water, it breaches the sandbar and flows out to the ocean. If this breach occurs at the farthest end of the estuary from the river inflow, then water must flow through the whole length of the estuary in order to reach the sea. Thus the entire estuary is flushed, and there is no deadwater. On the other hand, if the breach occurs near the river inflow, then most of the estuary will not be flushed by the flow of the river into the sea, resulting in a large deadwater. topography stub Category Estuaries ... more details

When the region is above sea level, as at the present time, rivers draining water from the land form, and these cut channels into the landscape.The rivers therefore strongly influence the topography of Paris. The Seine river cuts through Paris, but has apparently meandered in the past within a larger valley whose edges lie on the outskirts of the metropolitan area the edges of this larger valley are visible from tall buildings in Paris . Many of the hills in Paris, appear to be formed as the result of cutoffs from previous meanders in the Seine river, which is now largely channelized to maintain its stability.

The Christian Topography is a 6th century work, one of the earliest essays in scientific geography written by a Christian author. It was originally written as five books by Cosmas Indicopleustes and expanded to ten to twelve books around 550 AD. It is not known whether the word Cosmas is part of the real name of the author or a reference to the main topic of the text, namely a description of the cosmos . The work advances the idea that the world is flat earth flat , and that the sky heavens form the shape of a box with a curved lid, and especially attacks the idea that the heavens were spherical and in motion, now known as the geocentric model model of the universe. The author cites passages of scripture which he interprets originally in order to support his thesis , and attempts to argue down the idea of a spherical earth by stigmatizing it as Paganism pagan .

The pattern is focused on the anterior surface of the patient s cornea and reflected back to a digital camera at the centre of the bowl. The topology of the cornea is revealed by the shape taken by the reflected pattern. A computer provides the necessary analysis, typically determining the position and height ... corneal topography computerized analysis of photokeratoscope images.

File Sy1 2003 bearbeitet.jpg thumb 250px A Schlatt near the town of Syke, Lower Saxony Schlatt or Flatt is the Lower Saxony Lower Saxon name for a heathland pond, an undrained body of water usually shallow, that is fed by surface water and is largely unaffected by ground water . The water is impounded by a water retentive layer. Most Schlatts can dry out from time to time. Schlatts are characteristic of the nutrient poor geest topography geest ridges of the North German Plain . Most of them were formed as wind blown hollows in the periglacial region of the Weichselian Glaciation last ice age . The term is of Lower Saxon origin and is used mainly for the ponds in that part of Germany. In the district of Landkreis Diepholz Diepholz Lower Saxony the Conservation Foundation Stiftung Naturschutz has taken upon itself the preservation of Schlatts as part of a Schlatt programme. Using volunteers working with the land owners and farmers over 300 small ponds and Schlatts have been cleaned up and maintained in order to preserve them as habitats for threatened animal and plant species.

File D rpling hohe geest.jpg thumb A geest landscape near D rpling in Schleswig Holstein , Germany File L neburger Heide 109.jpg thumb The Osterheide a heath landscape on geest near Schneverdingen on the L neburg Heath , Germany Geest is a type of slightly raised landscape that occurs in the plains of in Northern Germany , the Northern Netherlands and Denmark . It is a landscape of sandy and gravelly soils, usually mantled by a heathland vegetation, comprising Glacier glacial deposits left behind after the last ice age during the Pleistocene epoch. ref Whittow, John 1984 . Dictionary of Physical Geography . London Penguin, p. 214. ISBN 0 14 051094 X. ref Geest lands are made up of moraine s and Sandur sandar s. They are almost always next to flat marsh lands, the geest being higher and better protected against flood but, compared to the marsh, with poor soil for agriculture. Where the geest borders the sea directly, sand cliff s exist. The oldest settlements in Northern Germany and Denmark lie on geest, since it provided better protection against storm flood s. Many important towns are on the boundary between geest and marshland where people could enjoy the flood protection of the geest but still use the much more fertile soil in the marsh. Examples of regions characterised by geest are the Burgdorf Peine Geest the Cloppenburg Geest near Cloppenburg the geest slopes between Wedel , Hamburg Altona and Hamburg Hamburg Neustadt and between Hamburg Hamburg St. Georg , Hamburg Bergedorf Bergedorf , Geesthacht and Lauenburg Elbe Lauenburg north of the Elbe the central geest areas of the islands of Amrum , F hr and Sylt the Hanoverian Moor Geest the Heide Itzehoe Geest the Linteln Geest near Kirchlinteln the L neburg Heath in Lower Saxony das Rehden Geestmoor the Schleswig Geest the Stade Geest near Stade the Wildeshausen Geest in Lower Saxony the Wingst ridge Wingst northwest of Hemmoor Lower Saxony See also Schlatt topography Schlatt References references Category Landfo ... more details
Image MoonTopoLOLA.png thumb right 345px alt Topography of the Moon measured from the Lunar Orbiter Laser Altimeter on the mission Lunar Reconnaissance Orbiter , referenced to a sphere of radius 1737.4 km Topography of the Moon. The topography of the Moon has been measured by the methods of laser altimetry and stereo image analysis, most recently from data obtained during the Clementine mission . The most visible topographic feature is the giant far side South Pole Aitken basin , which possesses the lowest elevation s of the Moon. The highest elevations are found just to the north east of this basin, and it has been suggested that this area might represent thick ejecta deposits that were emplaced during an oblique South Pole Aitken basin impact event. Other large impact basins, such as the Lunar mare maria Mare Imbrium Imbrium , Mare Serenitatis Serenitatis , Mare Crisium Crisium , Mare Smythii Smythii , and Mare Orientale Orientale , also possess regionally low elevations and elevated Rim craters rim s. Another distinguishing feature of the Moon s shape is that the elevations are on average about 1.9 Kilometre km higher on the far side than the near side. If it is assumed that the Crust geology crust is in Isostasy isostatic equilibrium , and that the density of the crust is everywhere the same, then the higher elevations would be associated with a thicker crust. Using gravity, topography and Seismology seismic data, the crust is thought to be on average about nowrap 50 15 km thick, with the far side crust being on average thicker than the near side by about 15 km. ref name W06 cite journal last Mark Wieczorek and 15 coauthors title The constitution and structure of the lunar interior journal Reviews in Mineralogy and Geochemistry volume 60 pages 221 364 date 2006 doi 10.2138 rmg.2006.60.3 first1 M.
