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...

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)

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)

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)

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)

Marine Asset Integrity Mapping

Using Multibeam Bathymetry, Topographic Laser Scanning & UAS Photogrammetry
Advances in marine & terrestrial scanning survey techniques together with precise inertial navigation sensors, multi-sensor acquisition systems and cost-effective UAS photogrammetry allow hydrographic surveyors to undertake high-precision marine asset integrity mapping. The benefit of this approach is that it produces a very accurate three dimensional digital elevation model that could be used as a baseline comparative survey to determine the long-term stability of sea walls and breakwater structures for engineering purposes. Marine GeoSolutions have extensive experience in acquiring combined multibeam bathymetry & topographic laser scanning datasets and partnered with Land Surveys to demonstrate the viability of this technology over a...

3D Web-Mapping

Integrating Marine Data into NASA World Wind
While Google Earth is the best known 3D web-mapping viewer currently in the public domain, there are alternative virtual globe viewers available. In particular, this article focuses on the NASA World Wind viewer, using OGC data-dissemination standards and multi-beam sonar data from the Irish National Seabed Survey to illustrate its potential. The creation of a range of innovative GIS tools and systems is enabling the harmonisation and electronic sharing of geospatial data and services across distributed networks. 3D web mapping viewers, such as NASA World Wind, are perhaps some of the most visible of these products. OGC Standards Such developments... (read more)
