Title
C&C Technologies Install UnderwaySV on High Specification Survey Vessel
Description
The UnderwaySV was installed on the R/V Thunder for a cable route survey off Alaska in July 2011. Local sound speed variability from freshwater runoff and surface heating could potentially wreak havoc on the wide swath multibeam data without adequate sound velocity (SV) profiles. To avoid survey downtime while gathering the required SV profiles, all casts were completed while underway using the innovative Oceanscience system. The small footprint winch system and simple installation procedure was ideal for the cramped deck. The Bluetooth wireless data management system made operations simple and efficient. The system also prevented the need to recover the sidescan towfish during SV casts.

Title
Extensão da Plataforma Continental (EMEPC) Use UnderwayCTD for Eddy Survey
Description
The EMEPC group, based in Paço d’Arcos, near Lisbon (Portugal) conducted an extensive survey on and around the Selvagens Islands in the Atlantic Ocean in June 2010. In addition to habitat investigations using an ROV, an Oceanscience UnderwayCTD (UCTD) system was used to conduct a study of a synoptic scenario in the ocean close to the islands. During this survey, EMEPC scientists on board the N.R.P. Almirante Gago Coutinho were able to conduct the deepest UCTD cast recorded in the year 2010, to 942m at 5kts.

Title
Impact of Typhoons on the Ocean in the Pacific (ITOP) Project Uses UnderwayCTD to Sample the Cold Wake of a Typhoon
Description
In order to conduct a rapid-response upper ocean survey investigating the effect of a passing Typhoon in the Pacific Ocean, researchers from APL used the UnderwayCTD on a continuous basis during a 20 day cruise. This unique freefall profiler was the main instrument used to accomplish the October 2010 cruise goals, and was augmented by gliders, fixed CTD stations, and a Vertical Microstructure Profiler (VMP). Round-the-clock UnderwayCTD operations achieved a record-breaking 2,917 profiles. Dozens of transects were completed, mostly at about 10kts with a spatial resolution of only 1km. The UCTD allowed high quality underway CTD profiles to be gathered at a lower cost, with less manpower than using larger towed systems.

Title
Norwegian Hydrographic Service Select the UnderwaySV for MS Hydrograf
Description
The Norwegian Hydrographic Service (NHS) conducted the first ever multibeam survey using the revolutionary new UnderwaySV sound velocity profiler to provide critical sound speed data in early 2011. The partnership of the Oceanscience Group’s underway deployment system developed for the UnderwayCTD, and the innovative Valeport “free-fall” RapidSV probe has generated the first compact and affordable, high-quality underway sound speed profiler. NHS surveyors have reported several benefits from their new profiling capability; better SV data, more efficient surveys, and a happier crew.

Title
UnderwayCTD Used on the Stratus Ocean Reference Station / VOCALS Cruises 2007-2010
Description
As some of the first oceanographers to use the Oceanscience UnderwayCTD (UCTD) profiler, researchers at Woods Hole Oceanographic Institution (WHOI) have been able to gather hundreds of CTD casts while in transit and during dedicated UCTD transects during the Stratus and VOCALS cruises in 2007-2010. The cumulative number of underway casts now exceeds 1,050. The WHOI experience has been crucial in developing the latest Series II UCTD, with feedback from three cruises used to drive design and operating procedure improvements. A recent WHOI investment in two upgraded Series II UCTD systems for future cruises, including the next Stratus cruise in 2011, will be rewarded by faster and deeper profiling capabilities.
