As shipping companies continue to make their operations more cost efficient and environmentally friendly, the demand for high density data has increased. Uncertainty management is...

Following the suspension of Parliament in the summer of 1858 due to the ‘Great Stink’, an act was passed to allow construction of a network of giant sewers, pumping sta...

High-resolution bathymetry and water quality surveys of shallow shelf and inland water bodies are an increasingly necessary part of environmental management with climate change pre...

My earlier articles on the alignment of motion reference units (MRU) with the ships reference frame (SRF) did not cover the calibration of GNSS augmented heading systems. Although...

In times past, it was often the lot of the hydrographer and ocean scientist to have hand-me-down ships and vessels from the naval service or revenue service of various nations. Or,...

Most continents have long histories of utilising their waterways to facilitate trade but, with a few notable exceptions, Africa has not yet taken full advantage of possible riverin...

An earthquake of unprecedented magnitude hit the east coast of Japan on 11 March 2011. A tsunami, a large wave caused by the earthquake, crashed into the ports and coastal regions,...

Seaports, waterways and climate are inextricably linked. Weather anomalies change bottom contours and destroy aids to navigation, compromising safety. In the past decade, maritime...

Recent hydrographic advances are revolutionising the way the marine environment can be accessed, scanned and quantified. With the emergence of sonar technology and, more recently,...

Over the years there has been a requirement to calibrate navigation (heading and motion) sensors and verify DGNSS systems on vessels working in the offshore oil industry. These cal...

Remote, difficult to access: it just depends on the point of view. Often, trying to reach some areas with a classical survey vessel or with an opportunity launch is like banging ou...

The ability to conduct inshore hydrographic surveys has always been dependent on small boats and the seamanship of those conducting the surveys. Besides the obvious use of small bo...
