Wishing you calm seas @alltooclearfilm.bsky.social! In partnership with @harknesslab.bsky.social and @lakeheaduniversity.bsky.social, we will be sinking an autonomous up-looking echosounder that will ping 24/7 to help understand the diel behaviour of fish and zoop at Sup Shoal. Be sure to tune in!

Measuring travel time and knowing the speed of sound in water, the echosounder provides depth measurements along swaths, which we combine to create bathymetric maps, revealing underwater landscapes, submarine volcanoes, and ridges.

A pretty solid read if you want to learn about CRS’s and the difference between a foot and a survey foot.

The future is #catostomidae... firmly believe that if there's a sentinel species that can tell us about enironmental changes, this group of fishes is it. Widely distributed, rarely targeted by anglers (and therefore don't need to worry about fishing mortality), and, I mean, just look at that face
There's a sucker (myth) born every minute. These are not trash fish.

Suckers are native fishes found across N. America. They are essential parts of the ecosystem. They're cool fishes to pursue.

This is why we turned on our multibeam sonar, which measures bathymetry at high resolution (~50 m/pixel) along the track of the ship, revealing spectacular highs and lows as we crossed the Southwest Indian Ridge a couple days ago.

Quote: "This situation shows why it's a bit of a risky proposition … to be relying on the industry to collect data that you're using to assess the fishery and then make decisions about how much quota the industry can take."
