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)

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...

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)

Multi-sensor Mapping

Integrating Data Streams for Coastal Science and Management
Among the most exciting advances in remote sensing are the innovations being made in multi-sensor data fusion. This can exponentially increase both the quality and quantity of information in the sensed environment. View Larger Map Scientists and practitioners in the National Oceanic and Atmospheric Administration (NOAA) and across the Federal government collect and use remotely sensed data for a wide range of activities including coastline mapping, military and disaster response personnel support, weather tracking, ecosystem monitoring and also to inform coastal planning officials and decision-makers on climate change adaptation strategies. Researchers continually strive to enhance the value, timeliness and efficient... (read more)

Mapping Northwest UK Seabed

The Maritime and Coastguard Agency (MCA, UK) and six partner organisations launched the Ireland, Northern Ireland and Scotland Hydrographic Survey (INIS Hydro) project at the Belfast Harbour Commissioners Office on Monday 4th July 2011. INIS Hydro, which receives GBP3.2 million from the European Union's INTERREG IVA Programme, will produce a standardised hydrographic survey specification and accurate high-resolution bathymetric datasets for seven important seabed areas to the east of Ireland/Northern Ireland and off the west coast of Scotland. A total of 1400 km2 will be surveyed by the partner organisation's research vessels fitted with multibeam sonar technology.   High-quality bathymetric information... (read more)

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. Acoustic sub-bottomprofiling... (read more)
