Antarctic Surveying

Every month we will focus on a specific theme, featuring a selection of articles which have previously been published in Hydro International magazine. By including a mix of older and more recent articles, we will present a complete recap of the subject. Furthermore, we will be bringing you a bi-weekly round-up of ‘Focus Stories’ related to the theme through our newsletter (sign up here). The theme for November 2017 is:

Antarctic Surveying

This Focus on GNSS is interesting as it covers a fascinating area, having its requirements for the surveyors’ skills and equipment. However, also alternative and small-scale approaches may work well.

The Pull of the Poles

The 2015 April issue of Hydro International considered the contribution of Forward-looking Sonar (FLS) to safer navigation in inadequately charted waters. Certain polar waters fall in this category; in recognition, some expedition cruise vessels have FLS. The extent of... (read more)

Echo Sounders versus Air Bubbles in Research Vessels

Within echo sounding circles it is well known that air bubbles may have a negative effect on echo sounding systems. This article briefly presents the German way of dealing with air bubbles from sweep-down and cavitation processes as well as our experiences with the last thre... (read more)

Different Approach to Surveying Antarctica

Navigation data is poorly available in Antarctica. If navigational data is available it often dates back to the early 1900s with many lead line surveys. An initiative was undertaken by Stephen Wilkins of Xplore Expeditions to collect bathymetry with a multi-beam survey syste... (read more)

International Bathymetric Charts

Since the 1970s, the International Bathymetric Charts (IBCs) of the Intergovernmental Oceanographic Commission have offered a framework for compiling soundings with a view to producing detailed maps of sea floor relief. Conceived in an era when marine cartography was still l... (read more)

Ice Navigation and the ­Electronic Age

Ice navigation is more of an art than a science, and like most arts, does not fit neatly into any scheme for enhancement by electronic means. It is an art learned in theory at navigation school, and perfected by many years of practical experience in forcing ships though ice.... (read more)

Sea Levels and the Coast

The oceans are a central part of the global climate system. As Roger Revelle, one of the early directors of the Scripps Institute of Oceanography, said, “The oceans exert a profound influence on mankind and indeed upon all forms of life on Earth. The oceans are inexhau... (read more)

Reservist Hydrographers in Mobile Survey Team

The Royal Australian Navy’s Australian Hydrographic Service has recently added to its survey capability with the innovative use of reservist hydrographic surveyors in a mobile survey team. Earlier this year, the new team undertook a proving survey on Great Keppel Islan... (read more)

The International Polar Year

Bathymetric mapping remains incomplete in the Arctic and Southern Oceans. Some proposed International Polar Year activities could help improve the situation by collecting new soundings during vessel transits to and from their operating areas, and by making their observations... (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 a... (read more)

Increased-resolution Bathymetry in the Southeast Indian Ocean

The disappearance of Malaysian Airlines flight MH370 on 8 March 2014 led to a deep ocean search effort of unprecedented scale and detail in the remote southeastern Indian Ocean. Between June 2014 and January 2017, two mapping phases took place: (1) a shipborne bathymetric su... (read more)

Autonomous Drifting Echo-sounding Buoys

Drifting echo-sounding buoys will soon provide bathymetric control in inaccessible areas of the oceans. The SSPARR (Seafloor Soundings in Polar and Remote Regions) buoy project holds great promise for providing very low-budget bathymetry. Initial buoy implementation may be b... (read more)

Surveying in the Extremes

In 2007, the National Institute of Water & Atmospheric Research's (NIWA) deepwater 70m research vessel Tangaroa returned from a voyage to Antarctic waters. It had here continued hydrographic survey work begun in 2001 for New Zealand's national hydrographic authority, Lan... (read more)

Learning Curve during Survey in Antarctica

The first Colombian scientific expedition to Antarctica was a major challenge for the country and the Colombian Hydrographic Survey organisation because of the extreme conditions in which the investigations had to be carried out. It is Colombia’s vision to contribute t... (read more)

Multibeam Systems for Extreme Environments

The search for resources and energy reserves for the future is continuously increasing in the polar region. More and more states are trying to stake their claims and to register their rights. For the same reasons, the clarification of the exact borders of the continental loo... (read more)
