OSIL to Supply Specialist Multi-Corer
OSIL’s (Ocean Scientific
International Ltd.) range of
Multiple Corers help collect an undisturbed sediment sample from the seabed. Each of the four corers,
Mega, Maxi, Midi and Mini, pro- vide a simple and reliable way of col- lecting the most accurate sample possible. The corers use a unique hydrostatically damped coring mechanism (penetration rate ~1 cm/s) to attain the undisturbed sample. The hydrostati- cally damped head allows a true representative sample that has not been disturbed by the bow waves seen in front of traditional corers. In order to fully maximize its use, the modified corer has been extended to provide a longer core tube length of 800 mm (standard length 600 mm), which will result in an increased sample for work/study. The cor- ers collect the undisturbed sediment sample together with overlying supernatant water, which provides a unique insight into the sediment water interface. The frame of the corers is made of 316 stainless steel and the core tub- ing itself of acrylic.
With a deployment rate of approximately 1m per second on the descent coupled with a retrieval rate at winch speed the corers are ideal for rapid assessment work. OSIL’s cor- ers are currently used worldwide by companies such as
IAEA, Petrobras, Altima, NOC, BP and The University of
Aberdeen. www.oceanscientific.com
Launch of Bathy DataBASE 3.1
CARIS released Bathy DataBASE 3.1, a move which the company claims continues to solve the demands for robust and scaleable data management for the storage and analysis of ever-expanding volumes of sonar and LiDAR data. Bathy DataBASE now works with Oracle Spatial 11g utilizing the GeoRaster and geo point cloud data structures for storage. Oracle Spatial has been specifically designed to meet the needs of advanced geographic infor- mation system applications. This latest release of Bathy
DataBASE expands the database system options available to clients following last year’s release of Bathy DataBASE 3.0, which offered the open source PostgreSQL database for backend storage. www.caris.com/products/bathydatabase
Hydrophones for Unique Use
Sensor Technology Ltd. received a repeat order for hydrophones custom-designed for a unique application in fire hydrants. “Most of our hydrophones are used in marine applications, where designing for survival in sea water is the standard. For this project, the hydrophones are used in pipes carrying drinking water to millions of people, so finding suitable, food safe materials was our major challenge.” said Harvey Ng, production manager at
SensorTech. The fire hydrants, by Hinni AG of
Switzerland, use hydrophones to detect leaks in the piping network. The sensors take sound measurements at pre- defined intervals and compare them to reference values.
Significant deviations from the reference indicate a leak. www.sensortech.ca www.seadiscovery.com Marine Technology Reporter 59
C-FINS for Real-Time Mapping of
C3 Submersible Fluorometer Data
Turner Designs introduces C-FINS (Fluorometric Integrated Nautical
Mapping System), integrating the C3 Submersible Fluorometer’s digital output with GPS data for data mapping. A simple software module enables C-FINS and ArcGIS to work together allowing for real-time map- ping of fluorescence, temperature, depth, and turbidity. The ability to cap- ture and integrate these data reliably using the C-FINS package is an enhancement to its C3 product line.
