Our group studies mosses in Antarctica. Long shoots of these mosses reveal information about past climate and are showing marked changes to current conditions. Changes in ozone and carbon dioxide are driving winds further south, resulting in increased evaporation and a reduction in the growing period. Our latest paper on this topic is in press in Global Change Biology (Bramley-Alves et al. Moss δ13C: an accurate proxy for past water environments in polar regions). Well done Jess! You can also listen to an interview on the ABC Science Show about an early paper by Laurence Clarke.
Over Christmas we made a tree from plastic we found on the beach at Strangles in North Cornwall and since then I have been taking photos of plastic on beaches around the world. So far not surprisingly Antarctica had the cleanest beaches. I didn't find any plastic washed up there amongst the penguins. However, if you look inside Antarctic birds they have plastic inside them
Here is a link which makes sobering reading. As Hardesty and Wilcox say in their Conversation article "the ubiquity, volume, and permanence of plastic waste demands better solutions" Eight million tonnes of plastic are going into the ocean each year
Jessica Bramley-Alves has spent a lot of time down South over the last few years. She had multiple summers at both Casey Station and on Macquarie Island as part of both her PhD and Environmental Science Honours research. Maybe all that cold has got to her because she has just started working at the Center for Urban Ecology and Greenery and National Parks Board of Singapore.
The moss team at Escudero base has dispersed. Sharon, Sarah and Andrew left by plane to Punta Arenas on Tuesday 20th. Sarah is now back in Portland and we are in Australia. Meanwhile Melinda, Angelica, Andreas, Todd, Hannah and Paz got onto a Chilean Navy ship, The Achilles, early on Thursday and are en route to Byers Peninsula for some Antarctic Camping! Gustavo, Marisol and Tavo are still at the Base. They should have more food now that we have left and the Achilles has resupplied them.
After a few days in the field collecting moss samples and becoming familiar with the many types of moss species living on King George Island, we had enough to begin experimenting in the lab.
