Businesswoman in the Middle East

Interview with Susan Murray, General Manager of the Seatronics’ Middle East office
Ms Murray joined Oceonics (the forerunner of Seatronics) in 1981. It was here that she got her first taste of business in the hydrographic Industry, specifically in the sales environment. After spending a couple of years gaining valuable experience with another equipment rental company in Aberdeen, she returned to Oceonics as Sales Manager. Between 1987 and 1996 she was the General Manager of her own equipment rental company in Aberdeen, selling this in 1996. In 2000 she decided it was time to move on and, believing herself too young to retire, agreed to take on the role of Middle East... (read more)

Measuring the Uncertainty of a Swath Bathymetric Sonar

A Statistical Analysis for System Performance and IHO Compliance
In the last few decades, substantial efforts have been made to improve and facilitate the way hydrographic data is obtained. One technology is the EdgeTech 4600, an interferometric phase difference sonar. Unlike traditional interferometers, the EdgeTech 4600 is the first of its kind to offer complete swath coverage of the seafloor, even at nadir. Combining this kind of coverage with a vertical accuracy that exceeds IHO Special Order requirements in depths less than 30 metres, results in a sonar with superior area coverage rates, especially in shallow water. In the summer of 2012, bathymetric survey data was collected using an... (read more)

The Study of Mapping the Seafloor

What is the Difference Between a Bathymetry Chart and a Hydrographic Chart?
This article will immerse you into the deep water of bathymetry. It explains in detail what a bathymetry map is, what it shows, what methods we use to collect the bathymetry data and, last but not least, how to create a good-quality bathymetry map. It will also cover the difference between a bathymetry chart and a hydrographic chart and the techniques our ancestors used in the past to collect and record depths. What is Bathymetry? Bathymetry is the study of mapping the seafloor. Bathymetric maps represent the ocean (sea) depth as a function of geographical coordinates, just as topographic maps represent... (read more)

Surveying in the Ross Sea

The deepwater research vessel Tangaroa of the National Institute of Water & Atmospheric Research (NIWA) of New Zealand undertakes regular research expeditions to the Antarctic waters. In the last eight years, this 70m ice-strengthened vessel has successfully completed seven voyages to Antarctica: three of which were to the Ross Sea. This article describes her 48-day voyage in 2006. During this latest voyage, she once again collected data to extend our knowledge of the geophysical and biological make-up of the Ross Sea region Looking Back Tangaroa ’s first voyage to the Ross Sea was in February–March 2001, when it undertook a...

The ROV in Nearshore Site Investigation

Nearshore engineering surveys are undertaken for the purpose of gathering information pertaining to the bathymetry and morphology of the seabed, along with the geotechnical characteristics and geophysical profiles of the sub-stratum. Standard practice tends to involve a low-resolution bathymetric and sub-bottom survey of the approximate area of interest, followed by a higher-resolution, site-specific investigation entailing detailed analysis of the location and form of the materials present. The traditional survey technique in the nearshore region is to use surface towed equipment and jack-up rigs, with diving teams and ROVs (Remotely Operated Vehicles) acting as support systems, performing very basic investigation tasks....

Surveying and Dredging in the Middle East

Interview with Charles Martin, Martin Mid East LLC, UAE
Charles Martin was born in Cape Town and schooled at Bishops, where he played moderate rugby, bad cricket and was a reluctant member of the choir for a few years. After a year compulsory internment in the South African Navy, he obtained a Civil Engineering Diploma and commenced his professional career by blasting away a large portion of Ben Schoeman Dock for Christiani Ham. He worked for Ham Dredging for eight years and National Marine Dredging Company in Abu Dhabi for twelve years before starting his own company in the United Arab Emirates (UAE). What is the history behind Martin... (read more)

The Dutch Sector of the North Sea

A geological introduction
The North Sea directorate of the Ministry of Public Works and the department of Geo-Marine & Coast of The Netherlands Institute of Applied Geoscience-TNO jointly carried out a geological mapping programme and the assessment of industrial sand deposits in the Dutch sector of the North Sea. A brief outline of the methods used and the knowledge obtained is given. The Dutch part of the North Sea (NCP) occupies an area of 57,000 km2 which is larger than the mainland of The Netherlands (Figure 1). In addition to traditional activities, like fishery and shipping, since the 1960s there have been new... (read more)

Minimising Offshore Survey Product Liability

In this article, offshore survey products are meant in the broadest sense. Not just survey, navigation and positioning, but the purpose or project that the dependent results are used for. No work in the offshore industry can proceed efficiently without good positioning data and survey information. From the initial 2D and eventual 3D surveys, through to the commissioning of the offshore installation and pipelines, offshore survey is the link between the various pieces of the complex puzzle. In this article, offshore survey products are meant in the broadest sense. Not just survey, navigation and positioning, but the purpose or project... (read more)
