The last few days we have been staying on the icebreaker Aurora australis just off the the Antarctic coast near the Australian base of Casey. For the operations team on the vessel, it has been a busy time, resupplying the station, bringing gear and waste offshore, balancing logistical needs against the ever changing weather. For those on the AAE, it has been a time for rest, work and reflection. Everyone seems to have slept – a lot. Afternoon naps are a common occurrence, and during lectures, no matter how interesting the content, many team members – including myself – have been known to doze off. No one seems to get upset by this; it’s just seems to be the natural way of things.
Alongside the daily programme of talks, the team have been working hard on the analysis of the scientific data we have collected. Erik and Chris have been working on the salinity and temperature analyses made during the voyage south and around Commonwealth Bay. Chris Fogwill has been drilling down with New Zealand and German colleagues into the origins of the sea ice breakout event that trapped the Shokalskiy. Kerry-Jayne has been looking at changes in sea bird data during our journey down to Antarctica and trying to make sense of it with Erik’s ocean observations. I’ve been working with Kerry-Jayne on the the census data collected at Cape Denison and the Hodgeman Islands to explore the possible role of changing climate on numbers. Alongside this, Eleanor has been mapping the glacial features she sampled around Commowealth Bay with Chris while Graeme and Ziggy have been carefully analysing the film footage they made of life – or lack of it – on the sea bed around Cape Denison. And on top of all this, Tracey, Naysa and Alicia have been working hard on the seal observations and sounds they’ve made and what this means for changing diet and population over time. All diligently supported by the science volunteers. Excitingly several of these projects are already reaping results that we hope to submit to research journals in the next two weeks.
Yesterday was a good news day. We heard the Shokalskiy has safely reached Bluff and all the team are well; so much so they’re heading off south again – this time for the Ross Sea – in just a few days. But the other great news is the resupply at Casey is finished and we should be leaving today. Our estimated time of arrival in Hobart is not confirmed yet but everyone on board is excited by the prospect of getting home and seeing loved ones. And just to round off a great day, the weather cleared and we were treated to a stunning sunset; the Sun dropped below the horizon in the early hours and the result was the most brilliant light that lit up the few clouds in a range a spectacular pinks. I could not resist sharing an image with you.
A huge thank you to everyone who has helped support the team and we can’t wait to see you all soon.
