Technical Instrument Training Course

The Technical Instrument Training Course is essential to ensuring safe operation of Rockland microstructure instruments and the collection of high quality data.  The Technical Instrument Training Course typically takes place over 3 days or as part of a 5 day Turbulence Workshop, which also  includes the Turbulence Education modules. Rockland instructors can provide individualized training focused on a specific microstructure instrument and the needs or your group. Rockland Scientific also organizes annual group training sessions for both Ocean Microstructure Gliders (OMG) and Vertical Microstructure Profilers (VMP). If you would like join a group training session or inquire about individualized training, please contact our Technical Support Team.

Over 3 days of training you will learn everything there is to know about the operation of RSI instruments and software, including deployment, recovery, maintenance, troubleshooting and data processing. The course includes a sea-going excursion during which the RSI equipment is deployed and recovered in field conditions.
