Today I had a field trip out to the Biological Station again for my Marine Methods course. The course teaches you different sampling methods for various substrates and depending on the aim of your experiment. Previously we did the typical rocky shore intertidal sampling with the squares, but today we played with trawls and dredges. It was cool being on the boat and the weather was perfect!!
