Underwater Sounds: Oil Rig Ferry

Whenever I have some free time I like to drop my hydrophones off my local pier. I am always hoping for some whales but more often than not it is just the sound of the shrimp, boats entering and exiting the 2 adjacent marinas (on the left and right), and sometimes even dolphins.

The ferry that picks up and drops off the oil rig workers happened to be making a drop during my last trip to the pier. Their boat makes some interesting underwater sounds.

There was also a dredge about half mile out; I couldn’t hear the dredging very well but I did get a couple of clips of the seafloor dirt being dumped by a barge. It sounds kinda like a metallic trash can.

Last but not least, the faintest of dolphin sounds. I need to get out on a boat and give these hydrophones a deeper dunk, fingers crossed for 2024.
