NOAA Uses RS to Monitor Algae

Using remote sensing technology, scientists at NOAA have developed a way in which to identify and monitor harmful algal blooms. This monitoring will help detect HABs along the coastal areas of the US, where they are causing concern, while providing more information to managers on how to reduce the impact of these toxic blooms. Scientists from the NOAA National Centers for Coastal Ocean Science are monitoring HABs using a combination of ocean colour satellite imagery with field and meteorological data. Satellites from the Sea-viewing Wide Field of view Sensor (SeaWiFS) owned by Orbimage provide information on the colour of the... (read more)

New Magnetic Survey System

Innovatum has announced availability of a new magnetic survey system for a wide variety of applications Ð the SEARCHER system. This is a new towed array tool providing highly detailed magnetic mapping, both on land and in marine environments. It consists of an array of magnetic sensors mounted on a frame, which may be towed over land or on the seabed or mounted on other underwater vehicles. A wide tracking swath allows a vessel to tow the array along a linear target such as a pipe or cable. High-speed data acquisition means the speed limitations of previous towed arrays are...

Canadian REA Analysis

OEA Technologies Inc. has initiated a study of Canadian Forces requirements and opportunities in the field of maritime Rapid Environmental Assessment (REA). The study, led by Defence Research and Development Canada Ð Atlantic (DRDC Atlantic), an agency of Canada's Department of National Defence, will capitalise upon OEA expertise in oceanography and DRDC Atlantic expertise in ocean acoustics. This investigation of REA expands on an earlier OEA/DRDC Atlantic investigation of the use of Earth-observation satellite sensors and coastal HF radar systems for purposes pertaining to military oceano-graphy. The previous investigation also involved representatives of Canadian Forces Meteorology and Oceanography (METOC) operation... (read more)

Autonomous Semi-submersible

Autonomous Surface Vehicles Ltd, with Seaspeed Technology Ltd, have exhibited the first 5.5-metre Survey Autonomous Semi-Submersible (SASS) vehicle. SASS vehicles are used to collect survey or surveillance data of all kinds from the ocean. SASS vehicles have both civilian and military applications, ranging from oceanographic and fisheries research to anti-terrorist surveillance and mine countermeasures. A detachable nose-cone enables a variety of in-water sensors to be fitted to suit any particular application. It can also deploy sensors or smaller daughter vehicles from a winch housed in the nose-cone. SASS involves an unmanned submerged torpedo-like body running below waves with a strong... (read more)

Measuring Waves in Makassar Strait

Fugro GEOS has successfully completed an oceanographic programme measuring surface and internal waves in the Makassar Strait, offshore East Kalimantan, Indonesia for the Total E&P Indonesia-Donggala project. The measurements were made using a single oceanographic mooring deployed in about 1,900m of water and serviced on a regular two-monthly basis over the ten-month period of the programme. The mooring had nineteen instruments configured to measure currents, waves, tidal elevations and seawater properties throughout the water column. The instruments consisted of ADCPs (acoustic Doppler current profilers), conventional rotor current meters, temperature sensors and a water level recorder. An important aspect of the... (read more)

First SHOALS-1000T Survey

Thales GeoSolutions (Pacific) recently completed a hydrographic and topographic LIDAR survey with the SHOALS-1000T laser bathymeter, the first time that SHOALS-1000T has been used for commercial applications. This was also the first time that hydrographic and topographic LIDAR data have been collected from the same airborne sensor. The system toggles between the two modes in mid-flight at the switch of a button and also comes fitted with a co-registered digital camera. The project specified the collection of data on the north-eastern United States coast in order to determine the existing conditions of harbours and harbour entrances, mainly focusing on the...

Water Framework Directive

OSIL is offering equipment packages especially for the purpose of coastal survey and monitoring work associated with the Water Framework Directive. Each package includes a Guildline MiniBAT sensor platform and a selection of key sensors for coastal sampling. The MiniBAT forms the core of the package and is perfectly designed for coastal sampling work, allowing undulating, constant, or fixed depth off-the-bottom profiles to be collected in depths of up to 60 metres and at speeds of 2-10 knots. In addition, the MiniBAT is lightweight and compact, enabling deployment from small survey vessels. The OSIL coastal monitoring package includes a choice... (read more)

Royal Navy Confirms Repeats Order of Valeport Products

Valeport announces that the Royal Navy has again chosen Valeport Model 740 portable tide gauges for use in its survey programme. Similar products ordered two years ago have proved so effective in application that a substantial new order has been placed by the Navy and supplemented by an additional order for Valeport miniSVS sound velocity sensors. As an addition to the standard specification, the 740s were supplied with a telemetry link so that the Navy could receive measurements in real-time. The miniSVS sound velocity sensors also supplied, use state of the art digital Ôtime of flight' acoustic technology to provide... (read more)
