Scotia Arc Expeditions 2011-2013

This expedition took a journey along the northern part of the Scotia Arc- the series of islands and ridges that track where Antarctica and South America used to join. The research aims to understand whether animals also use these places as a series of ‘stepping stones’ to travel between these continents. This is the second expedition to the area. Researchers plan to work on collected invertebrate animals and use the power of DNA to estimate how far these animals travel. This will help us determine if their movement patterns change in the future, when Antarctica might be a little warmer and a little different.

EchinoToL researchers, Greg Rouse and Mindi Summers, participated in the expeditions in 2011 and 2013.
