Multibeam training course in Portsmouth NH

My mate Mike Brissette from MosaicHydro is running a training course in Portsmouth NH in October. Mike is a fantastic tutor and I think they are using the Substructure vessel, which is probably the best inshore vessel on the Eastern Seaboard and one of the best in the world. More info below. Excellent price too for what you get.

New bathy LiDAR system

I got this through on an email the other day from Riegl. This is meant to sort out the problem of very shallow water but seemed quite far off being a product last year at ELMF. It looks like they have been working hard.

RIEGL VQ-820-G – Airborne Laser Scanner for Bathymetric Use

The VQ-820-G Bathymetric Airborne Laser Scanner with echo digitization and online waveform processing provides high speed, non-contact data acquisition utilizing a fast line scanning mechanism and a powerful laser source, emitting visible green laser light. For this particular wavelength, the instrument can measure the bottom of shallow waters due to low signal absorption in water. The VQ-820-G is designed to survey the coastline, the water surface, and the seabed or ground of a river or lake, depending on water turbidity. Laser

Operation Gooseberry

Here at NetSurvey we are just gearing up for Operation Gooseberry, which is a survey we will perform at the end of September of the British and Canadian D-Day Beaches (Gold, Silver and Juno).

As well as a survey it is going to be a joint training exercise with the UK Hydrographic Office. We will be training both NetSurvey and UKHO staff on how to install multibeam survey equipment, calibrate it, acquire the data and then process it.

I’m really looking forward to it as it will be a really interesting survey both from a historical perspective and also because we are going to be running the very latest firmware on our RESON Seabat 7125s and this will be the first outing of our new Optech ILRIS 3D laser scanner.
