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)

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... (read more)

Seismic Activity Data Collection on the Ocean Floor

Sponsored Article
Unlike neighbouring Japan, earthquake activity is infrequent in the peninsula area of South Korea, and those that do occur tend to be low in intensity. Typically, earthquakes in this region measure between 2.0 and 5.0 on the Richter scale[1]. The record for the quake with the highest magnitude on the Korean Peninsula stood for some time, recorded at 5.3 in 1980. This was recently overtaken by a 5.8 magnitude tremor in Gyeongju in 2016 and a 5.4 magnitude tremor in Pohang, followed soon after by a 4.8 magnitude aftershock tremor. Data on these events is collected using the existing seismological... (read more)

The Public-private Dilemma

Interview with Dr Cees Laban, marine project developer, Business Unit Geology, TNO
Privatisation as an answer to the financial challenges of survival has become a trend among public organisations, and hydrography is no exception. Private enterprise, worried about ‘unfair competition’, often looks with suspicion upon this. How are public-knowledge institutions currently organised and operating? Dr Cees Laban of the Geological Survey of The Netherlands agreed to be interviewed about his own organisation. Please outline for our readers how you as a geologist became involved in hydrography. From its inception, one of the main tasks of the Geological Survey of The Netherlands was mapping the subsoil of the Dutch land area. In 1968... (read more)

No Exploration without Hydrography

Harvesting minerals in the deep sea
According to a UN group of experts in 1978, "there can be no exploitation of marine resources without exploration and there can be no exploration without hydrography". For hydrographic surveyors this is quite obvious, but exactly how important is surveying in the seabed exploration business? And does hydrographic surveying play a crucial role in the decision making of the ‘seabed explorers’? Let’s take a small tour…. With general mapping for safe navigation purposes, harbour construction and maintenance, offshore and support activities for coastal protection, hydrocarbon exploration in coastal zones, survey and seismic activities for the oil and gas industry, and...

Southern Ocean Bathymetry

The Scientific Committee on Antarctic Research (SCAR) expert group for the compilation of the new International Bathymetric Chart of the Southern Ocean (IBCSO) proposes to build a consistent bathymetric database for digital ocean mapping of the Southern Ocean together with additional data that covers the ice shields of Antarctica, for example, radar satellite imagery, digital elevation models and free-air gravity from satellite altimetry. Acquisition, storage, compilation, and modelling of the heterogeneous data sets will be realised in a high-end GIS environment with server-GIS capabilities. Digital data processing throughout the work will facilitate the production of traditional printed maps and digital... (read more)

Australasian Hydrographic Society

News Australasian Hydrographic Society Lydia Taylor, AHS Education Award winner for Academic Year 2004, has reported on her participation in the scientific cruise led by Geoscience Australia in May 2004. The aim of the cruise was to look at the geology of a large, submerged continental block, the Kenn Plateau lying off the Queensland coast. The cruise was conducted on board CSIRO Research Vessel, the Southern Surveyor and involved extensive seismic, multi-beam, gravity, magnetic measurements and dredge samples across the plateau in order to investigate its evolution, structure and hydrocarbon potential. Her further research in 2004 involved the use of... (read more)

It’s on the Map – But Does it Exist?

In a reversal of the centuries-old tradition of explorers undertaking ocean voyages of discovery with the hope of finding new land, a scientific party from the University of Sydney, Australia, has done the complete opposite. They have solved a mystery regarding the existence of a supposed island in the Southwest Pacific. The Australian Hydrographic Service has added a further explanation of the phenomenon. The detective work took place on the RV Southern Surveyor, Australia's Marine National Facility research vessel, during a research voyage aimed at understanding the tectonic evolution of the eastern Coral Sea. Chief scientist Dr Maria Seton from... (read more)
