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...

Mapping Diamondiferous Gravel

Using the Aquares Resistivity System on a Fluvial Diamond Concession
An Aquares resistivity survey was carried out in a river in sub-Saharan Africa to map the sub-bottom features of a diamond concession. Diamondiferous gravels were distinguished remotely from bedrock and other soft sediments by the Aquares Resistivity System (ARS), a sub-bottom acquisition and profiling tool. It was selected due to its cost-effective operation and ability to provide qualitative and quantitative results. The ARS utilises recently developed processing innovations, which enable data to be presented in vertical sections and horizontal slices. This facilitates accurate volume calculations and the development of isopach maps for distinguishable types of bedrock and sediments.<P> View Larger... (read more)

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....

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)

Benthic Habitat Mapping

Utilisation of Multi-beam Backscatter for Ecological Study of the Seafloor
The establishment of multi-beam echo sounders (MBES) as a mainstream tool in ocean mapping has revolutionised approaches towards nautical charting, seafloor geotechnical/geological surveys and benthic habitat mapping. The resolution of bathymetric and backscatter data collected by MBES has improved significantly in recent years through technological improvements of these acoustic systems. Furthermore, developments in data collection and processing of MBES backscatter have resulted in the increasing preferential use of multi-beam technology over conventional side-scan sonar or single beam sonar for these applications. This article explores some recent developments in the methods used to generate benthic habitat maps using multi-beam sonar systems.... (read more)
