Airborne Oil Spill Remote Sensing

Remote sensing of oil spills in conjunction with their prevention and combat has long since evolved into a key element for the protection of the marine environment. The impact of oil spills caused by ship traffic and platform discharges has induced decision makers worldwide to establish airborne pollution surveillance services.<P> Assuming state-of the-artsurveillance equipment onboard the aircraft, these services can provide (1) flexible overviews of survey areas with regard to marine pollution and sea traffic, (2) quick assessments of oil spill sites, and (3) deterrence of potential polluters. Airborne pollution surveillance has proven to be an indispensable tool for the... (read more)

OSRL Tests and Validates Remote Sensing Equipment

A recent offshore exercise, conducted by Oil Spill Response Ltd. (OSRL, UK), was designed to understand how remote sensing technologies can help detect oil spills at sea more effectively. Utilising the latest in satellite, airborne and in-water surveillance and communications equipment, the successful event demonstrated the value of the technology in identifying and monitoring spills and was conducted with full approval of the Marine Management Organisation (MMO) following a rigorous planning and stakeholder consultation process. The main surveillance tools and providers involved in the exercise included: Radar and optical satellite imagery (MDA, Earth-I, Airbus, Telespazio) Infra-red and Ultraviolet sensors on... (read more)

2013 Pecora Award for Ocean Remote Sensing Scientist

The US Department of the Interior's U.S. Geological Survey (USGS) and NASA have presented the 2013 William T. Pecora Award for achievement in Earth remote sensing to Dudley B. Chelton, distinguished professor of Earth, Ocean, and Atmospheric Sciences at Oregon State University, Corvallis. Chelton was recognised on Wednesday 11 December 2013 for his contributions to ocean remote-sensing science, education and applications. The award was presented by Suzette Kimball, USGS acting director, and Michael Freilich, director of the Earth Science Division in NASA's Science Mission Directorate, at the American Geophysical Union meeting in San Francisco. Chelton is a pioneer in the... (read more)

Mapping the Seafloor with Remote Sensing and Satellite Imagery

An Analysis of the Techniques and Benefits of These Methods
70% of the Earth is covered by water, but so far just 7% of it has been surveyed (Mars, Venus and the Moon are better surveyed). Hydrography as a science has changed dramatically since the first measurements were made by Alexander Dalrymple and James Cook with lead lines and sextants. Singlebeam echosounders were invented in the 1920s – a technology still used today for mapping the seafloor. This method of using echosounders can produce very high-resolution bathymetric data but the high operational costs and the slow working process make it economically unsuitable for covering large areas. However, with the ongoing expenses of... (read more)

Sensing Earth

Medusa Explorations BV
In soil and sediment studies, geophysical mapping is often used as a prerequisite to focus or guide traditional sampling and coring of the locations of interest. This way, synoptic and concise information can be obtained about soil and sediment structure, composition and pollution. This concept has been a driving force behind the technology that Medusa has developed. Medusa Explorations, founded in 2000 in Groningen (the Netherlands), was a spin-off of the nuclear accelerator lab of the University of Groningen. The company aims to commercialise the results of 15 years of research and development focused on tailoring nuclear sensor technology for... (read more)

Remote Survey System

Clearpath Robotics from Canada has unveiled the Kingfisher M200 Remote Survey System, providing environmental professionals with an agile, customisable platform for remote sensing and environmental monitoring. Applications range from hydrology staples such as bathymetric data collection, shore erosion monitoring, sediment mapping and flow rate measurements to dam inspection and harbour safety. The newly refined features include semi-planing hulls for increased speed with less draw on power, a compact design, and electric jet thrusters that allow the Kingfisher M200 to traverse fast-moving water with ease. These adaptations make the newest Kingfisher suitable for performing dangerous, dirty, and dull jobs. The vessel... (read more)

Remote Hydrographic Surveying System

Staff at Frontier Precision, USA, have been working hard to design and build a safe, affordable and reliable hydrographic surveying system that is simple to use, and easily deployed. The boat uses an RC system that is integrated with a SonarMite high-accuracy echo sounder and a Trimble GNSS receiver which communicate via long-range Bluetooth, with a Trimble TSC3 running Trimble Access. This system provides safe data capture in otherwise challenging hydrographic environments or areas that are too small for conventional boats. In November 2013, one of the boats was used to perform a hydrographic survey of a utility crossing in... (read more)
