Tom Coad - Final Day Land ho! On the home stretch of our transit journey, spirits were high as we sailed into view of the picturesque Maria Island, albatross flying overhead in droves. We were warmly greeted by a truly spectacular sight as pods of dolphins came from all angles to escort us to our next sampling station. It was ‘action stations’ with four sites (13, 14, 15 and 16) to be sampled at Maria with seven hours to do so. These stations were of high importance, comprising the primary focus of the voyage, a perfect opportunity to calibrate the IMOS CO2 sensing buoy in the area. We began a transect out from the coast, starting at 40m depth progressing through 90 to 1000m with CTD deployments yielding CO2 samples that would achieve this task. Everyone had a bit of fun on the final CTD of the voyage, sending down personally decorated polystyrene cups to 1000m where the crushing pressure produced fancy little keep sakes. A momentous souvenir from our travels. The CPR was retrieved marking the end of our journey with final samples of chlorophyll, oxygen and salts being analysed. Valuable tutorials were also given on swath mapping, acoustics and how the underway pCO2 sensing instruments collect data. As the sun set over Maria, so began our last night on board the RV Southern Surveyor. The voyage was a fantastic experience, one I cannot recommend highly enough. I would like to extend huge thanks to both Zanna and Patti for their thorough planning and guidance and of course the 14 crew that made it happen.
