Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

We produced a new terrain map of the oceans from the best available resolution global bathymetry using a Geographical Information System. From this map, we calculated the following statistics for each sea and ocean, and each country’s Exclusive Economic Zone2: sea surface and seabed area, volume, mean, maximum and standard deviation of depth and slope. We found a total sea surface area of 353 million km2, seabed area of 354 million km2, and volume of 1 trillion litres or 1.3 billion km3. The deepest depth was 10,898 m in Micronesia, North Pacific Ocean. We found that the ocean was very flat; 71% of seabed had a slope of < 1o. We predicted locations of 56,741 seamounts (> 1,000 m high) with 74% within 30-min distance of known seamounts. We also identified over 1 million circular seabed features that may be seamounts or sea-hills.
