What does ES stand for?

Technologies, such as motion reference, multi-beam echo sounding and precise GPS positioning were used to paint a complete picture of each harbor's sea floor.

Vessels using sophisticated echo sounding technology are sweeping the waters between Malin Head in Co Donegal and Fair Head in Co Antrim.

The tests are conducted in the Strait of Juan de Fuca, Johnston Strait, at Whonnock in the Fraser River and at the Mission Echo Sounding test facility.

Repsol conducted its original work on Kaleidoscope with Houston-based 3DGeo, an imaging company founded by Stanford University professor and seismic imaging pioneer Biondo Biondi and Stanford University's Stanford Exploration Project (SEP), a leading industry-funded academic consortium, whose purpose was to improve the theory and practice of constructing 3-D and 4-D images of the earth from seismic echo soundings.
