Notes and a drawing of Ivy with Phaeophyceae (brown algae), I learned a lot and got down a Macrocystis rabbit hole. I’ve seen microcystis in my own water samples but that’s cyanobacteria if I remember right. Not the same, but the names make me feel like I’ve collected both things, a match set. What more is there to know

(A lot)

I wanted to see how tall M. pyrifera would be if it were stretched out like a tree (and needed a tree-person ratio) bc other kelp forest pics were too close-up I wanted to see how small that was. Also the way it grows/develops leaves is so good. Love it.

Then went “oh shoot,” that’s pretty deep. I wonder if there were bigger paleo (?) kelp forests. But yeah diving/living that deep does weird stuff with nitrogen so I wonder if that matters at all to them?

Leathesia marina/sea cauliflower

maybe not the prettiest seaweed overall, but personally I think the colour is really beautiful
