you should talk more about isiis-dpi it sounds neat as fuck

thanks for the ask! (i love yapping)

so i only started learning about the isiis dpi a week ago (im working with it for my summer job) so there will be much more infodumping in the future, but heres what i have to say rn:

- the isiis dpi itself consists of a camera and a light with a gap (~30cm) between them so when zooplankton find themselves in the gap they are backlit and cast a shadow to the camera

- the way the lenses are set up means that all the light crosses the gap as parallel rays so everything of the same size makes the same size image regardless of position in the depth of field

- the camera continuously records vertical lines of 2048 pixels (the image frame is 10.24cm high, hence 50micron pixel resolution) like a rolling shutter in a normal camera, only for longer duration. this produces a single super long image which is cut up into sequential square frames, and then further cut up to isolate individual particle or animal images

- when towed through the water at 2.5 m/s the camera can image more than 60 liters of water per second, nearly 4 m^3 per minute. there can also be multiple cameras (3 on the setup im working with) so its even more

- this setup has the dpi in the middle of an entire instrument platform the size of a small car (an rotv, remotely operated towed vehicle) that can record all manner of variables in the water column (depth, temp, salinity, chlorophyll, light, etc etc) as it is towed behind the ship

- the vehicle has wings and shit on it so it can be “flown” through the water column in a vertical zigzag pattern. this allows it to sample the entire depth range of the transect (i think we’re gonna do something like between 10 and 150m on the upcoming cruise)

- the actual data that comes out of this thing is really valuable because it lets us see The Squishies (small jellyfish, comb jellies, delicate worms, stringly mfs, various goop tubes) in their natural environment without obliterating them with nets and formaldehyde (look up jello tennis racket for visual aid)

- there is so much damn stuff in the ocean that this thing spits out literally millions upon millions of images, which absolutely cant be sorted by hand (i spent all day today sifting out just two taxa from a couple thousand images) so we need machine learning neural networks n shit to do it. this is what ai should be used for not whatever bs the tech bro oligarchy is tryna scam us with

- the algorithm kinda sucks ass unless you give it a huge amount of good training data, but the vast majority of the images are unrecognizable streaks and specks so i dont blame it

thats all i can think of rn but mark my words there will be more

did you know sturgeon are as old as the dinosaurs and did you know they don't have teeth and did you know they can live to be 150 years old and weigh 200 pounds and be six beautiful feet long and did you know I'm in love with them

wtf is rain world about all of your posts sound like “omg Stapled Macaroni Resting Upon A Rat is so cute :3” and show fanart of either a guy being held by one of those mechanical cranes or a girl on life support next to a rodent

look at the little guys i found them in a paper about an rebellatrix divaricerca (extinct coelacanth species) and have decided more people should see it because they are adorable
