The profiling velocity, W, of a VMP instrument is derived using the signal dP/dt from the integrated pressure sensor. It is imperative to have an accurate and high-resolution sensor to derive the rate of change of pressure, because it is used to convert the shear-probe data into physical units, and to convert the time rate […]

The VMP-250 features an integrated compound fluorometer and optical backscatter (OBS) sensor to measure chlorophyll and turbidity. This CLTU-VMP-250 sensor is co-located on the nose of the profiler with the microstructure sensors and designed for Rockland for vertical profiling applications. The CLTU-VMP-250 compound chlorophyll/turbidity sensor uses a light emitting diode for fluorescence and backscattering […]
London, UK, March 13, 2018 – Rockland and Alseamar are proud to show the results of their recent partnership. At the previous OI 2016, both companies agreed on a joint R&D program to develop a turbulence sensor payload for the Alseamar SeaExplorer glider. The first customer conducted successful deployments with the sensor payload, the MicroRider-SE, […]
“Boaty McBoatface” has executed its most daring dive yet. The nation’s favourite yellow submarine swam under a near-600m thick ice shelf in the Antarctic, returning safely to its launch ship after 48 hours away. It was an important test for the novel autonomous vehicle, which was developed at the UK’s National Oceanography Centre (NOC). Boaty’s […]
The recently completed InSTREAM project assessed fundamental differences in turbulent flow measured in the field, generated in a tank and simulated in a numerical model To mitigate the risk and uncertainty associated with turbulent flows in tidal channels, developers often use tank experiments and numerical simulations to assess the power and loading performance of a […]
OMG 2018 is a specialized training program for Rockland turbulence measurement systems that are integrated with ocean gliders. OMG 2018 will be hosted by the Mid-Atlantic Glider Initiative & Collaboration (MAGIC) at the Bermuda Institute of Ocean Sciences. Training will be optimized for both scientists and technicians and facilitated by instrument specialists from Rockland Scientific. […]
As part of the Oceans Sciences Meeting 2018, Portland OR, this town hall event will unveil recommendations and next steps towards improving the characterization of the LCS, based on findings from the Committee on Advancing Understanding of Gulf of Mexico Loop Current Dynamics. Rockland Scientific is proudly co-sponsoring this event held at the Portland Convention […]
With support from the ONR-Global program, the Environmental Fluid Mechanics Lab at UKZN, in collaboration with Rockland Scientific, is organizing a training workshop on Ocean Turbulence in January 2018. Rockland’s Dr Rolf Leuck, a leading international expert on the measurement of ocean microstructure, will lead the workshop. The course deals with both theoretical and practical […]
In 2010, 2-axis piezo-accelerometers (vibration sensors) and a precision inclinometer accurate to 0.1 degrees replaced three DC-response accelerometers in Rockland instruments. The new system produces far better low-frequency angle measurements and a much improved signal-to-noise ratio for higher frequencies. The purpose of the vibration sensors is not to quantify the acceleration of a VMP or […]
On Monday the W.M. Keck Foundation announced USD $1.2M of funding to build a Hadal Water Column Profiler (HWCP) that will permit new exploration and understanding of the ocean’s deepest regions. This uniquely capable profiling instrument will, for the first time: • enable high quality physical, chemical, and biological sampling of the water column from the […]
