CEE ECHO™

This guide may be used to check a test RAW file recorded in HYPACK to make sure the driver setup is correct. The time stamps of the recorded RAW data lines are inspected to check that the time stamps are written correctly and no time offsets are present. Time offsets might be very small – from a few milliseconds – to very large – several hours.

HYPACK offers two methods to acquire data when using CEE echo sounders with the proprietary time-stamped output format. When using the echo sounder and GNSS alone, as in most SBES surveys, the special CEE time stamps may be used for maximum timing precision. If using ancillary devices without time stamped data such as side scan, an alternative driver setup is required.

ACT Marine, a New England dredging contractor, uses a CEE ECHO™ with Hydromagic for its own QC and pre-final clearance surveys. The system sets up in 20 minutes, its results match the third-party survey, and projects are accepted on the final survey without costly post cleanup.

Blue Arc Engineering in Fort Myers, Florida swapped manual range pole and GNSS depth surveys for a CEE ECHO™ with Hydromagic and its existing Trimble R780. Fieldwork that would have taken a full day was cut in half, and the bathymetric product followed within days.

AOI Solutions surveyed a Daytona Beach retention pond, hit by hurricane Helene inflow and active backfilling, in 3 hours with a CEE ECHO™ and Hydromagic. An edited RTK-grade bottom surface reached the client three hours later, and the echograms showed both the sediment level and the original pond bottom.

Coastal Frontiers swapped its old echo sounder for a CEE ECHO™ on the San Elijo Lagoon Restoration Project, surveying lagoon depths typically under 4 ft (1.2 m) from a small boat or the CEE-USV™. Auto-gain and sensitivity cut collection and processing time, about 20 lbs of batteries were eliminated, and digital echograms in HYPACK replaced paper charts.

Copperstone Technologies fitted the CEE ECHO™ 33/200 kHz echo sounder to its screw-drive HELIX robot to survey mine tailings impoundments that manned boats and even small USVs can’t reach. It works with Hydromagic, keeps an on-board backup of the data, and the 33 kHz channel shows some surface tailings compaction.

In a San Diego Bay eelgrass survey, the CEESCOPE™ and CEE ECHO™ full water column echogram and HYPACK® editing mapped both vegetation extent and plant height on a 5 m x 5 m grid. Subtracting the digitized “real” bottom from the vegetation-top surface gives the height of the plants.
