eTrac recently collected topo data points in transects along a mostly shallow river in CA. This was an area boats and motorized vessels could not enter, but some of our dedicated crew could.

Sometime field work literally means being IN the field 😅

eTrac collected multibeam data over a 270ft historic shipwreck while working in the Great Lakes.

The steamer Sidney C. McLouth was built in 1880 and was used for package freight in the Great Lakes. In 1912, a fire spread on the vessel and the ship sank. The entire crew was able to escape safely.

eTrac has officially kicked off it's latest NOAA charting contract in Southern Green Bay, WI this week! The survey area, which spans from Southern Green Bay to Sturgeon Bay, was last surveyed in the 1940s. The area was determined to be statistically significant and in need of new data due to high vessel traffic and migrating shoals. Three eTrac vessels equipped with multibeam echosounder sonars will be used to collect high resolution sounding data of the lake. Conducting a modern bathymetric survey in this area will identify hazards and changes to the seafloor, provide critical data for updating National Ocean Service (NOS) nautical charting products and improve maritime safety.

To help improve the efficiency of the National Spatial Reference System modernization in 2022, eTrac employees are volunteering their time taking 4 hour GPS observations on passive control marks in their community. The benefits of these efforts will be seen in many industries from vehicle automation and energy exploration, to land surveying and Hydrography.

It’s been a while since all of eTrac came together in person, so we decided to come together in a slightly different way. Our employees participated in a beach cleanup over various local beaches! Beach cleanups are a nice way to give back to the marine environment we work so closely with year round.

We encourage you to bring a spare garbage bag with you the next you head to the beach! Even a few minutes makes a difference.
