The relationship between the gyre-scale circulation of the North Atlantic, represented by air pressure near to the centre of the sub-tropical gyre, and sea level measured at the eastern boundary of the ocean has been investigated using records commencing in the middle of the 18th century. These time series are twice as long as those employed in an earlier study of this relationship. Near-contin...

The shoreline is one of the most important features on earth’s surface. It is valuable to a diverse user community. But the dynamic nature of the shorelinemakes it difŽ cult to be represented in a naturally dynamic style and to be utilized in applications.The ofŽ cially usedshoreline,for examplein nauticalcharts,is the so-calledtide-coordinatedshoreline. It is also the shoreline that makes the ...

Ever since the first fishermen ventured into the sea, tides have been the subject of intense human observation. As a result computational models and ‘tide predicting machines’, mechanical computers for predicting tides have been developed over 100 years ago. In this work we propose a statistical model for short-term prediction of sea levels at high tide in the tide influenced part of the Weser ...

A continuous monitoring of sea level changes is important for human society since more than 50% of the world’s population live within 60 km of the coast. Sea level is traditionally observed with tide gauges that give measurements relative to the Earth’s crust. To improve the understanding of sea level changes it is necessary to perform measurements with respect to the Earth’s center of gravity....

Generating accurate and unbiased wall-to-wall canopy height maps from airborne lidar data for large regions is useful to forest scientists and natural resource managers. However, mapping large areas often involves using lidar data from different projects, with varying acquisition parameters. In this work, we address the important question of whether one can accurately model canopy heights over ...

. Abstract: Polychaete species composition, abundance and seasonal variation were analyzed in relation to Spartina alterniflora cover and tide levei at Ponta do Arrozal, Cananéia, during 1989/1990. Two intertidal stations were located on the S. alterniflora OOlt,one ca mean high water of neap tides (MHWN) and the other ca mean high water of spring tides (MHWS). Two other stations were establish...

Melting points and fusion enthalpies are predicted for a series of 81 compounds by combining experimental solubilities in a variety of solvents and analyzed according to the theory of mobile order and disorder (MOD) and using the total phase change entropy estimated by a group additivity method. The error associated in predicting melting points is dependent on the magnitude of the temperature p...

Different solvers for computationally difficult problems such as satisfiability (SAT) perform best on different instances. Algorithm portfolios exploit this phenomenon by predicting solvers’ performance on specific problem instances, then shifting computational resources to the solvers that appear best suited. This paper develops a new approach to the problem of making such performance predicti...
