Every month we will focus on a specific theme, featuring a selection of articles which have previously been published in Hydro International magazine. By including a mix of older and more recent articles, we will present a complete recap of the subject. Furthermore, we will be bringing you a bi-weekly round-up of ‘Focus Stories’ related to the theme through our newsletter (sign up here). The theme for April 2016 is Shallow Water.
An important area of work in hydrography is shallow water. This month, Hydro International collected papers focussing on shallow-water surveying. Interesting is that this field of work has multiple ways to collect the data: traditionally using a vessel but also techniques like Lidar, satellite bathymetry or hovercrafts (and smaller) are used.

Almost all (99%) international data is transmitted by around 265 subsea cable systems connecting the world. The total length of subsea cables exceeds 1.6 million kilometres, and th...

In order to meet the requirements of the European Water Framework Directive (EU-WFD), authorities face the problem of performing area-wide surveys of all kinds of inland waters rep...

Shore-based marine radar techniques have recently proved to be an excellent tool for monitoring erosion and accretion in the dynamic nearshore area through repeated and automated l...

In March 2015, Leica Geosystems conducted a series of demonstration surveys in Japan with the HawkEye III Airborne Topographic Bathymetric Lidar system. This demonstration was...

Due to their particularly shallow and turbulent thermocline, conducting seafloor mapping in lochs, fjords and other estuaries always presents a unique challenge to the hydrographic...

Interferometric sonars acquire millions of soundings in a hydrographic survey. The processing of this data by a hydrographer without a reliable statistical algorithm like CUBE (Com...

In June 2014, the Bureau of Economic Geology, a research unit at the University of Texas at Austin, was contracted to conduct an airborne bathymetric Lidar survey on the Alaskan No...

The River Murray Operations Unit (RMOU) of the South Australian Water Corporation surveys very shallow waters, a type of surveying that has its own specific problems overcome by no...

Proteus FZC, EOMAP and DigitalGlobe have formed a partnership to bring satellite-derived bathymetry and seabed classification to the hydrographic community. A pilot conducted by UK...

Since the management of coastal areas came to the attention of marine science, much effort has been expended in applying originally ‘blue water’ measurement technologie...

During the last week of a hydrographic survey of Lough Derg, Ireland’s third largest lake, the remnants of a preserved flooded landscape were unveiled beneath the surface wit...
