I recently delivered a public webinar to the Royal Society of Tasmania. In this lecture I presented my recent research into the response of the Southern Ocean to human-caused changes in the atmosphere. The lecture was recorded and you can view it online.

Ocean Sciences Meeting 2014
This post is mostly for people who are also at the Ocean Sciences Meeting, but if you’ve stumbled across this from somewhere else, welcome!
There were lots of details about my work that I wanted to share, but I couldn’t squeeze everything onto my poster. Even though the following details didn’t make the cut, I think that they’re really interesting and worth sharing. The rest of this post will make a lot more sense if you’ve read the poster first.
The PhD – One year down
I’ve just finished the first year of my PhD! As well as being pretty exciting, this means I got to present some of my work so far at the annual Atmospheric, Oceanic & Planetary Physics retreat.
Read on for a whirlwind tour of what I’ve been up to for the last year.
Ekman transport: icebergs and algae
Imagine it’s the late 19th century. You’re a famous Norwegian Arctic explorer, and you want to be the first person to make it to the North Pole. Fridtjof Nansen was in just this position when he proposed his second voyage; freezing a ship in the sea-ice to spend three years slowly drifting across the pole. It’s an interesting tale, but I’ll leave it to others to tell.
His relevance to this post comes from his observation that icebergs don’t drift downwind; rather they move at an angle to the wind. Nansen presented this riddle to Vagn Walfrid Ekman, who in turn presented his answer to the world in 1905.
