Scotia Arc Expedition

Scotia Arc Expedition

These expeditions in 2011 and 2013 took SIO scientists on 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. Researchers will identify the collected invertebrate specimens and use genetics to estimate how far these animals travel. This knowledge will help us determine if their movement patterns will change in the future, when Antarctica may be warmer and different.
