Hi! I’m Frankie Pavia, a PhD student at Lamont-

Doherty Earth Observatory in New York working with Robert Anderson. My research focuses on ocean chemistry, specifically on radioactive isotopes produced naturally in the environment (yes, there is lots of natural radioactivity!).

I also study Earth’s how Earth’s climate has changed naturally in the past. My role aboard the cruise is to collect deep cores of the seafloor, which is layered by time (the deeper you go, the older you get!) to investigate how the physics of the Southern Ocean were different during the last ice age 20,000 years ago.

This is my second time at sea but first time in Antarctica!

Marlo Garnsworthy

Science Communication & Outreach

Hi, my name is Marlo, and I am a writer, illustrator, and editor.

I have always been an adventurer. When I was a little kid, growing up in Australia, I was fascinated by animals and the natural world. I enjoyed looking under rocks and wading in ponds, climbing trees and making bird calls. When I wasn't outside, I was drawing and reading books. Today, I love all these things just as much as I did when I was little.

I have dreamed of going to Antarctica for as long as I can remember, and I am beyond thrilled to spend a couple of days at McMurdo Station. I'm also really looking forward to the ice-breaking portion of our cruise as we travel north through the Ross Sea and to seeing Antarctica's unique wildlife in its natural habitat.

My role aboard the cruise is to communicate our science to you and keep you in touch with our journey via our social media pages. I'll also be taking lots of photos and making art, as well as working on a book about our experience.
