An orange Bovallia gigantea perched on seaweed.

The last time we talked, I briefly mentioned the objective of our experiment for this field season. If you don’t remember, let me refresh your memory.

A chart showing local wind speed forecasts and actual speed and gusts. I had planned for this post to be about diving, but we’ve done much less of it so far than expected. Why you might ask? Because of the weather.

A semi-transparent pteropod (sea snail).I am going to expand on the excellent introduction Hannah gave you to the science of ocean acidification (OA) in an earlier blog. In doing so, I will highlight some of the bigger picture implications of ocean acidification globally. I will focus on two different cold-water geographic regions of the world and for each briefly highlight the impacts of ocean acidification on key, ecologically or economically (or both) important marine organisms. Both regions are ‘hot spots’ for ocean acidification.

Addie standing in the zodiac boat, steering with one hand and holding onto one of the boat ropes with the other, ocean, glacier, and blue sky behind her. After settling in, the team began preparing for our first dives, and there was a lot for me to learn. We practiced setting up a tent and starting a camp stove in case we could not get back to station due to weather and had to seek refuge on an island. We also learned how to tie various hitches and knots for use on the zodiac boats.

A dark-colored limpet in a lab tank. It’s a cold winter’s morning. You sit in the driver’s seat of a car and turn on the engine, giving it a few minutes to warm up before making your morning commute. Perhaps, instead of a car, you are on a bus, train, or plane. In all of these scenarios, you are producing a common thing. Carbon dioxide (CO2).
