‘Hydrography’

Why is this book different from the wide range of books on hydrography? As an oceanographer I have spent a lot of time reading books on the general knowledge of hydrography. Most of them are self-explanatory. However, they hardly ever cover half the range of topics that are the building stones of hydrography. The authors of this book have set out to and succeeded in presenting an introduction to and overview of the broad field of hydrography. It is impossible to cover all these topics in great detail, as such a book would be far from enjoyable to read. However,... (read more)

Hydrography: Teamwork

Our profession is one that carries with it lots of wonderful things. Travelling to remote places, exploring new territories, fighting the elements, providing new routes as well as improving existing ones for mariners, all belong to the uniqueness of being hydrographer. But these tasks and conditions also demand that hydrographers work very closely together, both in the field and between field parties and the office, to achieve the aims of a survey. Facing adversity as teams of professionals and technicians, along with the hydrographic vessel crew, nurtures very bonded human relations. Relations based upon the shared sacrifice of being away...

Chinese Hydrography

The Chinese Dragon rears its head in many fields of the world economy and despite the latest reports of a slowdown of growth, it is interesting to see the development in hydrographic surveying and chart production. The Chinese hydrographic sector is certainly increasing. Let’s take a look at a few figures from the Chinese Maritime Safety Authority, under which the Hydrographic Office falls, laid down in the annual report of 2010. The Chinese surveyed 26,814.89km2 in 2010, compared to 15,722.42km2 in 2006. Of this total, 6,209.5km2 was surveyed in the North Sea area, 10,830.94km2 in het East Sea Area and... (read more)

Hydrography 2.0

This month's theme is hydrography and living resources. However, you won't find any articles on the subject in this magazine. A bit strange coming from me, who for years worked in nature conservation. Like a doctor not seeing his own kid is ill, or a contractor not working on his own house in his spare time. But I haven't developed a blind spot for living resources, just sometimes a theme comes up that's too interesting too ignore. In promising to make it up to you over living resources, I would like to introduce Hydrography 2.0!   Invite you into a... (read more)

World Hydrography Day: Hydrography For Maritime Trade

The International Hydrographic Organization (IHO) celebrates World Hydrography Day (WHD) on 21st of June, this year carrying the theme Hydrographic Services - the essential element for maritime trade. This is the anniversary date on which the IHO was created in 1921. The theme for each year's celebration highlights aspects of the work and the contribution that the IHO makes to the world community. For 2010 the IHO has chosen the theme, ‘Hydrographic Services - the essential element for maritime trade'. Maritime trade is extremely important to most countries in the world, and hydrography and the provision of nautical charts are... (read more)

South Pacific Hydrography

In April this year I represented the South West Pacific Hydrographic Commission (SWPHC) at the eleventh meeting of the Pacific Islands Maritime Association and the first Meeting of Pacific Minsters of Transport. During the discussions I was reminded of the unique challenges the South Pacific Ocean has for hydrographers. A relatively small number of ships transit about 16% of the earth’s surface, some 41,500,000 square kilometres of this falling within the boundaries of the SWPHC. Distances of 2,000 to 3,000 kilometres between the ports of the region are common. The South has a few sub-Antarctic Islands buffeted by the Roaring... (read more)

How Important is Hydrography?

The link between the development of a State and its trade was identified centuries ago. In spite of the efforts of countless projects, the awareness of the importance of charts and maritime safety information to the overall development of some States has been generally unsuccessful. How can this be improved?<P> The efforts of the IMO, IHO and ­Inter­national Association of Lighthouse Authorities are well known and recognised, but how can anything be achieved when major international funding for purely maritime safety projects is limited. Apart from separate initiatives by the aid agencies of a number of developed States, funding for... (read more)

Hydrography by the State

Legislation varies from country to country, with respect to the definition of the maritime, fluvial and lacustrine spaces administered by the state. In general, the sea floor and the water column are encountered seawards from the line defined by the lowest tide. A similar situation is found in navigable rivers and lakes, where the river or lake floor is found from the their normal lowest level. Another space is also found between the lowest and the highest tide or the normal lowest and highest level of rivers and lakes: the beach. In some places a third sector also exists: the...
