Products The Sea Owl can work in any orientation, including upside- down. Sea Owl ROV The Sea Owl concept introduced by Saab in the 1980s, has been com-pletely reengineered with new chassis, advanced technology content and in- creased work capability. Now named Sea Owl XTi, the new design offers 360° orientation, allowing the ROV to work in any orientation, even upside- down. The result is a vehicle made for hard-to-reach places and hostile envi- ronments that combines the character- istics of a highly maneuverable obser- vation vehicle with the versatility of a larger ROV. Key features: a doubling of the payload, extreme maneuver- ability courtesy of seven thrusters and a new depth rating to 2,000m. www.seaeye.com SediMeter with Integral CleanerLindorm, Inc. in Miami is releasing two new SediMeter versions. The SediMeter measures a vertical turbid- ity pro le through the bottom using an array of 36 OBSes, with 1 cm spac-ing. The bottom level is also estimat- ed based on the collected data. The SediMeter was designed for studying erosion, sediment accumulation, silt-ation, scour and sediment transport on the bottom of the sea, lakes, reservoirs and streams. These new models are permanently sealed and use recharge- able batteries. They have an UW-plug- gable connector in one end for battery charging and communication. www.lindorm.com MacArtney Updates MERMAC ROV Winches MacArtney Group introduced the newly upgraded MERMAC R series of ROV winches. Featuring high pow- er and speed, minimal maintenance requirements, a rugged and compact design, Active Heave Compensation (AHC) and a unique Remote Diag-nostics Tool, the MERMAC R se- ries promises to deliver cutting-edge winch solutions for ROV systems and tasks of all types, MacArtney said. Employed for work class and inspec- tion ROV systems alike, MERMAC R winches are available as standalone systems as part of launch and recovery packages or as part of complete vessel moon pool handling solutions.www.macartney.com Characterization of Hazardous Ocean Ice There is an increasing need for  ne scale detection and characterization of hazardous ice conditions in the Arctic. ASL Environmental Sciences Inc. has recently received funding from the Canadian Space Agency to address this need under the Earth Observation Applications Development Program. The project will develop improved techniques, tools and data products that will enhance the detection and characterization of hazardous ice conditions at  ne scales, based on advanced beam modes of RADARSAT-2, and the unique capabilities of moored, upward looking sonar technology. ASL?s Ice Pro ler along with Acoustic Doppler Current Pro lers will provide validation data and opportunities for im- provement in the analysis and interpretation of the SAR imagery. In effect, this project will combine the view of the ice canopy from below (Ice Pro ler) with the view from above (RADARSAT-2 high resolution quad-polarized data), and gen- erate enhanced ice information products. Using simulated data for Radarsat Constellation Mission compact polarimetry beam mode, the operational utility of such products will also be assessed.(Photo: Saab Seaeye) November/December 201356 MTRMTR #9 (50-64).indd 56MTR #9 (50-64).indd 5612/13/2013 12:28:29 PM12/13/2013 12:28:29 PM
