Featured Product The New RBRsolo T RBR Ltd. released the new RBRsolo T: RBR?s smallest, lightest, and most versatile single channel logger. Tested in harsh environments to ensure per- formance, the RBRsolo T provides reliable temperature measurements even in the most unpredictable conditions. The RBRsolo T is ideal for long term deployments, bore holes, extreme environments, or anywhere where size is a concern. Even though the RBRsolo T is small in size, there is no need to sacriÞ ce when it comes to deployment performance. The RBRsolo T can take up to 20M readings on a single battery, samples up to 2Hz, provides three years of sampling at Þ ve second intervals, has a depth rating of 1700m, and uses true USB data download for speed and convenience. The RBRsolo T is equipped with a pressure-protected thermistor which has a 0.8 second time constant, providing reliability under varying deployment conditions (initial ac- curacy ±0.002 °C). The temperature logger offers exceptional stability; drift is typically less than 0.002°C per year.

The HADCP is used for gathering critical current measure-ments for ship navigation in the port. The Clear Signal coated HADCP has been deployed since April 2011. The Clear Signal is designed to greatly decrease biofouling accumulation, cleaning times, and as reported by the Port of Vancouver diving contrac- tors, left no residual biofouling. The Port of Vancouver had suffered extensive biofouling on its HADCP instruments causing unacceptable maintenance costs. The Clear Signal Biofouling Control System is a robust coating that the ,manufacturer says has been proven to withstand the rigors of port and harbor use.

Designed for subsea equipment manufacturers, the low inser- tion loss and back reß ection make this connector suited for high speed data and video transmission. The rugged stainless steel design warrants the robustness and reliability of the connector, whether mounted on the deck of a vessel under harsh sea con- ditions, on an offshore platform, or at full ocean depth. In step with the trend toward smaller equipment, the new addition to the OptoLink range has been developed to offer reliable and efÞ cient Þ ber optic connectivity in a minimal sized connector. Especially in proportion to the fact that (as a standard) the OptoLink Single Fiber Connector features a full ocean depth rating of 6000m - the connector is very compact. In addition, the OptoLink Singe Fiber Connector is engineered for minimal weight. In practice, this entails that the connector applies a minimum amount of strain on for instance small and medium sized ROV?s, thus allowing them to carry more equipment. The single Þ ber (single pass) OptoLink connector is available in a bulkhead (BCR) and cable mount (CCP) conÞ guration with minimal attenuation between the mated connector pairs. Further- more, it is available in both single and multi mode. The connectors have SS316 stainless steel housing as standard, however, other shell materials are available upon request. www.macartney.com Marine Technology Reporter 59www.seadiscovery.com MTR #9 (50-64).indd 59MTR #9 (50-64).indd 5912/3/2012 11:00:01 AM12/3/2012 11:00:01 AM
