Snowed In

We just weathered two, plus, days of ‘white out’. That’s when there’s so much snow in the air that you can’t see more than a few meters ahead, especially if you’re located where there is… {Read More »}

Setting up Royds Penguin Camp

Two of us, Jean Pennycook (a science teacher) and I, arrived at Cape Royds, landing by helicopter chock full of food boxes, camping gear, and scientific equipment. Back in the cargo portion of the helo,… {Read More »}



Adventures with Adélie Penguins at Cape Royds in the 2007–08 Austral Summer

We have set out in the 12th year of a project in which we seek to understand why Adélie Penguin populations have been increasing in the Ross Sea since the early 1980s, and why the… {Read More »}
