I've just realised that we haven't put up any of the results from the Cornish Survey yet on the blog, so here is an image I made from the Fledermaus scene of our bathy data combined with the EA's topo LiDAR data around St Michael's Mount.

Mark and Andrew have been up in the Orkneys surveying for renewable energy firms the last two weeks. This was the first time we have had a chance to use the new RESON mounting bracket for our 7125-SVs. Apart from a few small design faults (bolt lengths, etc) it worked very well. As you can see from the photo the bracket is designed for both the 400 kHz and the 200kHz transmitters with just the 400 kHz shown. The receive array is broadband so it can listen in to both frequencies

Combining multibeam bathymetry and laser scanner data gives you the best of both worlds above and under the water. The best thing is that it is very simple to do an very cost effective. You can collect both at the same time or go for laser at low water and multibeam at highwater to get a bit of overlap. Other great applications are cliffs, bridges, beachfronts, basically anywhere you want seamless coastal zone data. Here's an image of one of the results.

NetSurvey have been contracted by BP Angola to supply quality control personnel for a 3 month AUV survey in Block 31 Angola. This is the third time BP Angola have contracted NetSurvey. NetSurvey will use IVS3D Fledermaus software to identify problem areas of data and to process data for BP.

The survey from Lizard Point around to Lands End is almost finished. The weather has been worse than last year, which is saying something, but Max, Rob and JP have done some sterling work, getting into areas which we never thought we would get in. For instance they collected 100% coverage data behind St Michael's Mount. The image is the survey coverage so far completed.

NetSurvey are currently surveying off Lands End and also up in the Shetland Isles.

The Lands End survey is for Channel Coastal Observatory and the Maritme & Coastguard Agency. The survey is from Lizard Point to Lands End and extends from Mean Low Water Neaps out to 1 kilometre. Rob Bertram and Max Fisher are the NetSurvey personnel involved. They are running a Kongsberg EM3002 dual system with an Applanix POS MV 320 on the vessel Remote Sensor. The picture attached is of the vessel surveying with St. Michael's Mount in the background.

The survey in the Shetlands is also for the Maritime & Coastguard Agency and is part of NetSurvey's ongoing multi-year contract on the ETV Anglian Sovereign. Paul Robertson and Andy Sinclair are the senior surveyors up there. Already our survey has uncovered a 6m rock pinnacle where it was supposed to be 60 m of water on the chart! We submit H102s to the UKHO when we find significant differences to the charts which are then broadcast as a Notice to Mariners.

Paul Robertson, Mark Bennett and Max Fisher completed a multibeam survey of all the shipping channels in Bermuda in three weeks. The Bermuda Marine & Ports Department contracted NetSurvey to perform the survey. We mobilised a RESON Seabat 8125 and an Applanix POS MV 320 onto one of the department's pilot vessels, the St David.
