Waterside Mapping

Laser scanning and bathymetric side-scan sonar represent the cutting edge of environmental survey technology. Over the last few years, we have tested the integration of these two methodologies, carrying out a number of high-resolution surveys on the Po River, the Venice canals and various Italian harbours. Bathymetric surveys were conducted using a SEA SWATHplus-H wide-swath sonar. An Optech ILRIS-3D terrestrial laser scanner was used to scan the areas above water level. Information from these scans was used to create 3D black and white images (intensity images) of the surveyed area. In the case of the laser scanner, these images are... (read more)

Arctic Mapping

Mapping the American and Canadian Continental Margins Around the North Pole
For the third consecutive summer, the United States and Canada teamed up with their icebreakers in August to tackle the technical aspects of mapping their continental margins in the Arctic Ocean. However this time they included in their survey a zone of dispute that was much closer to shore. The teams reported that the two previous joint expeditions with the U.S. coast guard cutter Healy and Canada's Louis S. St-Laurent icebreaker have tripled the amount of bathymetry and seismic data collected from the western Arctic. "Last year's survey was extremely successful, and the ice conditions permitted the ships to collect... (read more)

Mapping the Future by Mapping the Past

How Maritime Archaeological Research is Training Tomorrow’s Marine Scientists
This article describes the internship programme that has been offered during six years while performing maritime archaeological projects in the Mediterranean. This collaborative effort between academia and industry provides affordable manpower, whilst interns have a chance to learn and experiment on significant discoveries as part of a closely-knit group. After their internship, motivated interns benefit from broad experiences and contract opportunities. This introduction to quasi-professional employment contrasts with typical commercial operations in terms of pressure and learning opportunities; an approach that translates into continued success for the organisation and the majority of summer interns being motivated to further their career in...

Energy for Oceanographic Mapping

Oceanographers at the University of Alaska Fairbanks are installing a new alternative energy device along the arctic coast of Alaska. After two years of design and development, the device will provide power to scientific instruments in remote areas, where sources of electricity are often scarce. The device, called a remote power module, is equipped with four wind turbines, a solar array and a backup generator. The wind and solar energy provide five days' worth of battery charge. If the batteries get low, the module recharges using a biodiesel generator.Scientists will install the module in Barrow this month and test it... (read more)

Seabed Mapping Solutions

IXSEA launched its new seabed mapping brochure at Ocean Business 09 in Southampton today, which includes the new ECHOES 1500 Deep Tow sub-bottom profiler.     "The launch of ECHOES 1500 Deep Tow at Ocean Business, a step change in sub-bottom profiler technology, demonstrates the diversity of the IXSEA product range," said IXSEA's Offshore Director Richard Parkinson. "DELPH is a powerful suite of real-time data acquisition and fully integrated processing and interpretation tools. While SHADOWS, the fourth generation side scan sonar, provides ‘more pixels per hour'."     (read more)

Maritime Animal Mapping

CSIRO scientists from Australia have learned animal trekkiing quirks by fitting them with electronic recording and transmitting devices, setting them free, and studying the information they retrieve. King penguins in the Indian Ocean ride ocean currents to eddies rich with fish before making a bee-line back to their chicks. European eels navigate to ocean currents and make deep dives to dodge predators on their 5,000 kilometre migration from Ireland to Bermuda to breed. More than 250 specialists in the use of telemetry devices (tags) to study animals meet in Hobart from 14-18 March at the Fourth International Science Symposium on... (read more)

Submerged Aquatic Vegetation Mapping

In July 2007, a hydrographic survey team from Duck (NC, USA) mapped 6.7 square miles of the Currituck Sound in water depths of less than 3m. The aim was to chart the depth and identify areas of submerged aquatic vegetation (SAV) around the proposed corridor routes for the mid-Currituck Bridge. The team used a pontoon boat equipped with a GeoSwath Wide Swath Sonar along with bottom grab samples to produce a bathymetric map and identify a total of 1.31 square miles of Submerged Aquatic Vegetation (SAV).   Hypack survey software was used to navigate the boat along pre-programmed survey lines...

3D Web-mapping

Integrating Marine Data into Google Earth
Google Earth has become a popular 3D web-mapping viewer, mainly due to the richness of satellite imagery in its primary database. However, the database contains very limited marine data. While the addition of marine data would be welcome, this article explores the use of Web Map Service (WMS) and Keyhole Markup Language (KML) to overlay large-scale multi-beam imagery datasets from the Irish National Seabed Survey into the Google Earth viewer. Over the last seven years the Irish National Seabed Survey (INSS) has returned many terabytes of multi-beam sonar and ancillary data, providing detailed bathymetry data and knowledge of seabed characteristics....
