As the Great American IV speeds along the South Atlantic, the ocean will look much the same to Rich as it did during his race in 2008. But if you look closely, there have been some pretty big changes in our global ocean and in the climate of our planet. Let’s start...
Are more icebergs breaking off Antarctica due to a changing climate, or not? Perhaps there is another reason that the hazard has moved north?
Hi Rich: First off, congratulations on your progress! It looks like you’re only some 170 nautical miles from the ice exclusion zone! The ice exclusion zone has grown from your last race, and the main reason is that the number of icebergs sailing around the Southern...
Several times I was in Corsica on a boat trip and I could see once a whale and once dolphins. You’ve been sailing for years – have you seen a decrease in marine fauna?
Dear Axelle, The sighting of a whale or a dolphin is so special every time, and as a sailor I feel lucky whenever I see them! But it is really hard for me to say if I’m more or less lucky this year over the past. The thing is, all these big animals are really...

“It all started in a dinghy. I grew up on a big lake system in Finland and spent most of my summers sailing around in small boats. Once on the water, I was captivated by the mystery of what was going on beneath the surface. Are we sailing over a school of fish? What are they eating? Why is it that the water changes color in the spring and the autumn? What does the bottom look like, and what animals live there? Such questions were always with me on the boat, so when it came time to think about school, it was clear what I wanted to study.
“By graduate school at Northeastern University, I’d narrowed my focus to corals. I traveled to Jamaica and Australia to scuba dive and conduct my research on the reefs. But I still loved sailing, and the bigger and deeper the waters under the keel, the more curious I grew about the ocean ecosystem, the plankton, the algae, the fish, and the ocean currents.
“For the past 15 years, I’ve been lucky enough to pursue these questions and combine sailing and science on board Sea Education Association’s sailing research ships. With a group of undergraduate college students, we sample the ocean as we sail from places like Hawaii, Tahiti, New Zealand, Fiji, and Samoa in six-week stretches across the equatorial Pacific. My questions haven’t changed much over the years, but they’ve become more focused. Why do some particular kinds of fish or zooplankton live in the equatorial ocean, near a particular current? Why are they around in such different numbers from one year to the next, and what changes in their world? On every trip there are surprises, and ocean has always something new to teach me.”
