Full Scale GeoEel LH-16 Data Graphic
To address the need for increased resolution required for windfarm construction and other construction, Geometrics developed the next generation of the GeoEel electronics – The LH-16. The new system allows:
A test was conducted by Fugro using a 72 channel GeoEel system with 1-m spacing and Fugro positioning and multilevel stacked sparker in the Murray Firth. The results show seismic resolution that has not been achieved before with multi-channel systems. Signal was recorded out to 5kHz which allowed vertical resolution that approached 10 cm while still maintaining imaging features as deep as 30 m below the seabed.
Source intervals for the survey shown are at 0.5m and 1m spacing which required the time between shot intervals to be a short as 0.2 s.
