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)

Grand mapping coalition

The need to build a grand coalition of mapping partners all over the world, from all corners and professions of the maritime community, is more urgent now than ever. During a one-day symposium -  From Vision to Action hosted by the Nippon Foundation-GEBCO Seabed 2030 Project Seabed, held in London on 22 October - it was once again emphasized that the creation of a definitive global ocean floor map by 2030 would support the sustainable use of the ocean and lead to sound policy decisions regarding the seas and their coasts. During the symposium, three new initiatives were revealed. It... (read more)

Coastal Mapping Project Completed

Fugro, USA, has completed data acquisition and processing of the entire United States West Coast under a contract with the U.S. Army Corps of Engineers (USACE) in support of the National Coastal Mapping Program. The company's efforts earned Fugro the USACE 'LCDR Peter Johnson Best Practices Award' at the recent Joint Airborne Technical Center of Expertise (JALBTCX) Annual Airborne Coastal Mapping and Charting Workshop. This major, multi-year effort covered a 1,500m-wide ribbon, extending 500m inshore to 1,000m offshore, along the coastlines of California, Oregon and Washington. Over three survey seasons, approximately 2,000km of coastline were surveyed.  This marks the first... (read more)

Habitat Mapping - Increasing Importance

Two decades ago as CO of a survey ship, I interpreted the SSS-registrations (still on wet paper) twice. Once was for nautical charting purposes and the second, in my own time, was simply to ‘get the most from data collected at high costs’ (my hobbyhorse) when I made a bottom texture chart for those institutions interested. Since then, for various reasons e.g. a growing concern about the environment, more and more habitat studies are now conducted, ranging from baseline surveys to full-blown scientific studies. The multidisciplinary studies are mostly based on hydrographic charting specifications and data quality methods (which I... (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)

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)

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....
