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)

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)

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)

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)

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...

Offshore Innovation and Improvisation

Key Elements for Successful Geotechnical Investigations
Geotechnical investigations for offshore constructions require continuous technical innovation in order to meet market demands. This is also relevant to the growing offshore wind energy industry, which is itself on a path of constant innovation. The daily costs of offshore operations are high, meaning that honouring a contract satisfactorily and on time is important. To achieve this, improvisational skills are vital to overcome the challenges that may occur while testing and boring at sea.<P> The world’s first offshorewind farm was constructed just off the coast of Vindeby (Denmark, see Figure 2) in 1991, when GEO – the Danish Geotechnical Institute...

30+ Years of Hydrographic Education

Category A Programme of Hamburg’s HafenCity Universities
A hydrographic education programme has been offered in Hamburg for more than 30 years. The programme was first offered in 1985 as an addition to an existing programme in general surveying, and the course became fully recognised as a Category A programme by the IHO in 1990. The Hydrography programme has been integrated as a specialisation in the two-year MSc in Geodesy and Geoinformatics at HafenCity University since 2009. In March 2017, the current programme was re-recognised as one of the first against the new standard S-5A. With the new recognition in place, the programme has shown that it is... (read more)
