We are excited to bring back our Photo of the Week section so stay tuned for new content coming soon! In the meantime, take a look at these fantastic pictures from our teachers.
“Hydrographic survey launches can go to shallower depths than the large hydro ships, allowing them to get much closer to shoals and the coast.”

Small boats play a big part in hydrographic surveying.

In general, the survey launches do the same work as the <i>Thomas Jefferson</i>, just on a smaller scale. The <i>TJ</i> can only drive on lines with a minimum depth of 30 feet, but the survey launches can go to a minimum depth of 12 feet which allows them to get much closer to shoals and the coast. Every morning, the launch survey teams have a meeting to discuss logistics and safety. My boat was headed out to survey grounds on a new sheet near Cape May, New Jersey. Specifically, we were driving lines in the Prissy Wicks Shoal. This particular region has highly variable depths and created quite a challenge for two reasons: you cannot navigate in straight lines over shoals, and the shoals constantly change so you must drive slowly in case an area is shallower than charted." - Yaara CraneRead the blog post
