Rockland and Dalhousie University researchers combine to develop solutions for turbulence measurement at in-stream tidal power sites.

The need for improved knowledge of turbulence statistics in tidal energy generation has led to a trans-Canadian collaboration between British Columbia-based Rockland Scientific International (RSI) and the Ocean Acoustics Laboratory (OAL) at Nova Scotia’s Dalhousie University to develop advanced techniques for turbulence measurements at turbine ‘hub height’.These new techniques will be traceable to a laboratory […]

Despiking Data

Spikes in data can be caused by environmental debris in the water column (phytoplankton, jelly fish, etc.). Regions of high biological productivity are more likely to result in lots of spikes in your data set. Such spikes can change the spectra and skew estimates of dissipation. Despiking detects anomalous, stand alone spikes in data and […]

Converting Raw Data Into Physical Units: odas_p2mat

A second cornerstone of our ODAS Matlab Library 4.0 is the new function odas_p2mat.  odas_p2mat uses the configuration information embedded in the RSI data file to convert the binary data into data vectors in physical units for both raw signals and derived signals. The data vectors created by odas_p2mat are saved in a mat-file with the same name as the p-file. […]

A Quick Guide to quick_look.m

A cornerstone of our ODAS Matlab Library 4.0 is the new and improved quick_look.m.  quick_look.m visualizes the content of an RSI data file, the p-file, computes spectra for a selected range, and returns a profile of the rate of dissipation of turbulent kinetic energy.  First, data is converted into physical units by calling the new function odas_p2mat.m.  After data […]

Introducing ODAS Matlab Library 4.0

Welcome! We are very excited to unveil our new website. Please take the time to click around to see what information is new and updated. This first blog post is an opportunity to introduce you to our exciting new product available on our website: ODAS Matlab Library 4.0. The new ODAS Matlab Library adds a […]

Time Steps Closer to Development of Industry Guidance on Tidal Turbulence to Reduce Risk for Industry

Rockland’s strategic UK partner, Partrac, has announced that the TiME (Turbulence in Marine Environments) project is entering the final stages of data analysis following the success of turbulence measurement surveys. The project, developed to improve the understanding of the effect of marine turbulence on tidal arrays in Scottish waters, is being delivered with partners Ocean […]

VMP-250 hands-on demonstration at Ocean Business 2015

RSI is hosting a hands-on demonstration of the VMP-250 microstructure turbulence profiler as part of Ocean Business 2015, NOC Southampton. This course is free to attend, but registration is required on the Ocean Business 2015 website. The demonstration will be in two parts: a 1-hour field demonstration and a 1-hour classroom session.  Wednesday, April 15, 1:30 – […]
