Algologies: Seaweed Under the Microscope

These are a series of experiments made using my own microscope (which is normally used for looking at samples of bacteria). The seaweed samples were collected from the Undercliff, rinsed in warm water and the put in water in a Petri dish (as shown below). Antonie van Leeuwenhoek, one of the fathers of microscopy is believed to have first observed algae in 1674, using a tiny handheld microscope. I have a replica one but it’s not possible to capture the images from it with a camera. It’s not exactly possible identify all the images but I believe the samples were Ulva, Coralina officinalis, and the invasive species Sargassum muticum but it’s hard to be sure as I’m still a beginner and mainly using the book “Seaweeds of Britain and Ireland” which seems the best resource I’ve found.
