2. Hydrodynamic Services
(Waves & Tides)
Wave buoys
6 Directional Waveriders deployed originally
External contributions
Efficiency savings
Extra 6 deployed (plus 1 spare) making total of 12 wave buoys around the coast
Tide gauges
2 WaveRex tide gauges originally deployed
Extra 2 gauges deployed (1 WaveRex and 1 Etrometa Step Gauge) and 1 changed from WaveRex to Etrometa Step Gauge making total of 4 tide gauges around the coast

6. Bathymetric Surveys
Full bathymetric coverage from Portland Bill to Second Severn Crossing
Unexpected weather meant it took 5 years to complete
Multibeam surveys for Lyme Bay (Portland Bill to Torquay) and Mounts Bay
Singlebeam surveys for rest of coastline
Annual singlebeam surveys of Exe and Teign estuaries
Multibeam for Exe estuary 2010 survey

7. Majority of work done in 2007 and 2008, extension started and completed in 2009.
Hardest part of the coastline was Sennen to St ives, most done in 2010 and finally completed at the beginning of 2011.

8. Topographic Surveys
Full topographic surveys for all original management units
Initial baseline survey
Annual baseline (BMP) survey if designated
1 or 2 interim surveys per year
Partner requests
Efficiency savings
New surveys for management units around mouth of Taw / Torridge estuary including annual baseline surveys
6 sites changed to include annual baseline surveys

10. LiDAR Surveys
Unexpected weather caused alterations to original survey plan
Entire coastline has at least 1 flight
Most places have 2 flights
Many places have 3 flights
Several places have 5 flights

12. Aerial Photography 2 full sets of orthorectified aerial photography
Unexpected weather caused delays in data collection
2006, 2007 & 2008 first set
2009 & 2010 second set
