Data Integration for Coastal Surveying

Combining Laser Scanner and Bathymetric Sensor
When surveying the coastline, the integration of bathymetric (below sea level) and laser scanning (above sea level) data causes problems due to the different imaging properties. However, by ensuring that the different data sets have been accurately georeferenced and oriented, a complete and accurate model of the terrain above and below sea level can be obtained. This technique was employed to survey the area of Portovenere in Italy, including the San Pietro church located on a steeply sloping rocky promontory, with positional accuracies in the order of 5cm.<P> View Larger Map One of the biggest issues incoastline survey is the...

Coastal and Marine Spatial Planning

On 14th December 2009, US' President Obama's Ocean Policy Task Force released its Interim Framework for Effective Coastal and Marine Spatial Planning (Interim Framework) for a 60-day public review and comment period. With competing interests in the ocean, the coasts and the Great Lakes, the Interim Framework offers a comprehensive, integrated approach to planning and managing uses and activities.     Under the Framework, coastal and marine spatial planning would be regional in scope, developed cooperatively among Federal, State, tribal, local authorities, and regional governance structure.  Everyone is encouraged to comment by mid-February 2010.     (read more)

Innovation in Coastal Water Monitoring

HCTECH is a technology-based company that started as a spin-off of CIS (Centro de Investigaciones Submarinas SL) in Santiago de Compostela (NW Spain). It was founded to improve the management and to further develop the technical know-how gathered during 10 years of R & D in CIS. The company is dedicated to the designing and manufacturing of water quality monitoring systems and other marine technologies. CIS (Centre for Submarine Investigations), founded in 1987, is an environmental consulting company, specialised in the marine environment. For over a decade, CIS maintained a research, development and innovation department that ­generated techniques to prospect... (read more)

Coastal Monitoring of Water Quality

Autonomous Surveying of Shallow Coastal Waters for Clean Seas and Shorelines
The wave-propelled AutoNaut unmanned surface vessel (USV) completed a short trial off the south-west coast of England to monitor the water quality by a sewage outfall. AutoNaut demonstrated its ability to reliably operate in shallow waters whilst also recording and transmitting data. A suite of sensors aboard the USV worked in conjunction with satellite data from synthetic aperture radar (SAR). Analysis indicated that the seawater close to the outflow was not negatively affected. The combination of technologies is pioneering for the application and the trial highlights the potential of this innovative approach to conduct long-term marine monitoring – including the...

Indian National Coastal Surveillance System

Defence and security company Saab was in November awarded a SEK116 M (approximately EUR 12,2 Million) contract from the India Directorate General of Lighthouses and Lightships (DGLL) to deploy a coastal surveillance system covering the entire Indian mainland coast. The national coastal surveillance system will encompass 74 sensor locations, six regional control centres and three national control centres, most which will be connected by broadband satellite links. The contract includes options to add another 12 sensor sites in the future. The sensor sites will be equipped with redundant Saab AIS base stations that will identify and track the movements of...

Maps Will Help Turn Ocean Into New Economic Boom Zone

China will accelerate its pace of mapping the deep seabed, Zhang Jixian, president of the Chinese Academy of Surveying and Mapping, told China Daily in an exclusive interview. In the near future, China's surveying and mapping science will gradually extend from the ground area to the country's 3 million square kilometres of water territory.     Unlike the electronic navigation chart released by the Chinese navy on 25 Augustus with information mainly focusing on navigation, the future ocean map will concentrate on the geological features of the sea floors and the water depth, and the location of reefs. In the... (read more)

Bed Mobility in the Weser Estuary Turbidity Zone

Mud in its unconsolidated, highly dynamic, fluid state may complicate problems arising from other detection difficulties in estimating water depth in estuarine channels with mobile bed deposits. This study presents new results on riverbed mobility in the turbidity reach of the Weser estuary based on datasets from an Innomar sediment echo sounder (SES-2000) and combined fluid mud sampling. Many estuaries of the world are important waterways. A high sediment turnover leading to highly dynamic mud deposits and large bed-forms such as sub-aqueous dunes is a characteristic feature of tidal estuaries. Often their presence poses navigation risks due to considerable reduction... (read more)

Robots Help to Map England’s Deep-water Marine Conservation Zone

The first true three-dimensional picture of submarine canyon habitats has been produced using a combination of marine robotics and ship-based measurements. The information captured in this set of maps ranges in scale from the 200km canyon down to the size of an individual cold-water coral polyp and will be used to inform the management of the only English Marine Conservation Zone in deep water. This ‘nested map’ is the result of a recent scientific expedition to the Whittard Canyon in the Bay of Biscay, led by the National Oceanography Centre (NOC). It works in a way not unlike a set...
