Valeport Debuts rapidCTD Automated Pro? ler

Designed initially to operate autonomously with the Tele- dyne OceanScience rapidCAST automated underway pro? l- ing system, Valeport’s new rapidCTD pro? ler with Bluetooth technology is targeted at the shallow water survey market as an evolution of the Valeport fastCTD and rapidSV that makes underway pro? ling work faster and more ef? cient. The pro- ? ler includes a conductivity cell designed for optimum ? ow- through, a fast responsive thermistor sensor and a 0.01 per- cent accuracy pressure sensor, synchronously sampling at up to 32Hz. Valeport said the rapidCTD will include an optional

Fluorometer sensor and an enhanced, rechargeable battery

Valeport later this year.

Buoy System Based on Campbell

Scienti? c Dataloggers

Construction upgrades at Costa Rica’s port of Limon required monitor- ing of sea-surface meteorology, including wind speed and direction, air temperature, barometric pressure, humidity, water column currents, sea- surface temperature and turbidity. Contractor RDSEA designed a buoy system using a Campbell Scienti? c CR6 datalogger and sensors that included a Campbell OBS501 turbidity probe and a Teledyne ADCP.

The buoy was deployed in March 2016 and immediately began trans- mitting wet-data daily via Campbell’s LoggerLink app on the project lead’s smart phone until the initial phase of the monitoring project was completed.

AutoNaut

Autonomous Boat

Monitors Ocean Noise

Plymouth University Marine Institute scien- tists are working with AutoNaut and its nearly silent 5m wave-propelled USV, which tows a

Seiche Ltd passive acoustic monitoring array, on a project studying how increasing levels of manmade noise in the sea is affecting marine life. Two days of initial trials of the autonomous concept were completed in July, and PAM data will now undergo a technical analysis.
