First Ocean Acidification Experiment

I am excited to be running my very own ocean acidification experiment!

For the last two months I have been planning and executing an experiment testing the feeding behaviors and abilities of Nucella dogwhelk snails from different sites in different pH treatments. To my great satisfaction, everything has been working according to plan. As a result of this experiment, I will witness sunrise outside every day for at least 14 days straight! Hooray!

Thanks sooo much to the volunteers who have helped me every step of the way. You guys are super great!

Enjoy these pictures of the process!

bins covered with acrylic sheets weighted with cinder blocks.

We even do it all in the rain!

The little mussel was eaten by that snail!

This snail has its proboscis through the hole it drilled in the
right valve of this mussel. Since the mussel is open, you can see
the snail's proboscis on the inside!
