Efficiencies in Coastal Zone Mapping

Hawk Eye II, the unique airborne laser technology from aerial imaging specialist Blom, is flying high at Ocean Business with a high speed upgrade delivering faster, more efficient data gathering and imaging for shallow water and coastline surveys.     The only technology able to capture accurate data simultaneously from both land and seabed terrain, gathering bathymetric, topographic and photographic imagery all in one pass, Hawk Eye LiDAR is already proving a valuable tool for enhancing the feasibility, quality and speed of coastal and nautical mapping, operating at typically 60% of the cost of traditional hydrographic survey methods and with...

Mapping Cold Water Coral Reef

In recent trials off Trondheim, Norway, the GeoSwath Plus swath bathymetry and side scan system was used for the first time on a remotely operated vehicle (ROV) to map cold water coral reefs. The objective of the survey was to test how effective the GeoSwath was as a ROV mounted sonar for identifying cold-water coral colonies. At 60m deep the Tautra ridge in Trondheim Fjord is home to world’s shallowest known cold-water coral reef, and was an ideal site for initial system trials. The corals seen there usually thrive in much deeper waters.  The GeoSwath was deployed on a Minerva... (read more)

Mapping Inspired by the Imagination

Sand maps were commonly used by Indigenous Australians over their 40,000 year history, to communicate local topography, significant landmarks and the location of water.
Recently, I had the opportunity to visit the Australian National Library in Canberra to view the exhibition ‘Mapping Our World: Terra Incognita to Australia’. This exhibition showcased some of the most significant milestones in the history of mapping and discovery of Australia and included Australian Indigenous paintings, a Babylonian clay tablet thought to be the oldest surviving world map, the works of Ptolemy and rare medieval maps. It also explored the development in projections by Mercator and chronicled the expansion of Dutch commercial trading and the voyages of discovery of the Portuguese, Spanish, English and French. Maps have stirred the... (read more)

Mapping a Roman Shipwreck Site

A 3rd century AD Roman shipwreck site, off the coast of Sicily has been inspiring archaeologists with its array of historical treasures. The wreck site was first discovered in May 2006 under 92 metres of water during a survey of the Sicilian coast. It was an enormous find with an artefact distribution suggesting it was once a vessel 15 - 20 metres long, possibly larger.   Objects recovered from the wreck site included ceramics, concretions and possibly hull timbers. These artefacts are currently undergoing extensive study to identify the date and further detail of the ship and its final journey.... (read more)

INIS Hydro Seabed Mapping Project

Maritime & Coastguard Agency
Since January 2011, an ambitious EU-funded seabed mapping project has been surveying and charting 7 key marine areas off the Republic of Ireland, Northern Ireland and the west coast of Scotland. Their mission? To harmonise and integrate cross-border baseline marine data collection between the UK and Ireland. Led by the UK’s Maritime & Coastguard Agency (MCA), INIS Hydro is a groundbreaking scientific partnership between 7 leading marine organisations, drawn from across the British Isles: · Agri-food & Biosciences Institute (AFBI); · Geological Survey of Ireland (GSI); · Irish Marine Institute (MI); · Northern Lighthouse Board (NLB); · Scottish Association for...

Jason 2 Begins Mapping Oceans

Less than a month after launch, the NASA-French space agency Ocean Surface Topography Mission (OSTM)/Jason 2 oceanography satellite has produced its first complete maps of global ocean surface topography, surface wave height and wind speed. The new data will help scientists monitor changes in global sea level and the distribution of heat in the ocean.     This information is used to monitor climate change and ocean circulation, and to enable more accurate weather, ocean and climate forecasts. The data reveal patterns of sea level anomalies, which are used by scientists to calculate the speed and direction of ocean surface... (read more)

Integrated Mapping of Seabed Features

Dual use Hydrographic Surveys for Seabed Nature and Morphological Research
The Italian Navy, using survey vessel Ammiraglio Magnaghi and personnel from the “Istituto Idrografico della Marina” (IIM), in cooperation with ENEA Marine Environment Research Centre, surveyed the Levante Canyon system, located in the offshore area of “Cinque Terre”, eastern Ligurian Sea, NW Mediterranean. The purpose of the operation in the area depicted in figure 1 was on the one hand to collect the data necessary for the updating of nautical documentation and on the other hand to carry out scientific research on the seabed nature and specifically on deep coral banks. Italian Navy Ships are equipped with state-of-the-art equipment and... (read more)

ESRI Mapping Center Improving Maps

ESRI has launched Mapping Center, a new website that helps users learn about cartographic concepts and best practices for mapmaking with ArcGIS. The site is designed to provide quick answers to mapmaking problems. Site visitors will find information and sample maps displaying a wide variety of cartographic techniques and effects along with tips and instructions on how to reproduce the featured effects on their own maps.   The application aims to encourage ArcGIS users to employ the same concepts when using geographic information system software that professional cartographers do when making maps. ESRI thus identifies and supports members of the... (read more)

GIS in Mapping Ocean Floor

Ocean Globe from ESRI Press examines bathymetry from its early history through today's use of geographic information systems (GIS) and other technologies to map the ocean floor. With contributions from oceanographers, explorers, and historians, this new book is a valuable resource for those interested in coastal management, seafloor mapping, and marine biology. The anthology addresses how recent developments in bathymetry and seafloor mapping are applied to animal migrations, coral reef growth, tsunami forecasts, coastal ecosystems, aquatic farming, whale habitats, and more. In addition, the book includes a special appendix on the history of seafloor mapping-from early line-and-sinker methods to multibeam... (read more)
