How many scientists does it take to play a board game? Enough to break the ice.
Welcome to CAPSTAN Voyage 2, a collaborative program to give young scientists an opportunity to experience marine research and life at sea. Step one of our journey required an introduction to each other and to the various disciplines that fit under the marine research umbrella. Geology, Chemistry, Biology, Oceanography and Geophysics just to name a few. One of the best ways we found to get to know each other was by playing board games at our accommodation in Hobart prior to boarding the RV Investigator. Teams were created and friendships born through rummy-cube, Monopoly and Settlers of Catan. It’s amazing how easily the group connected with their common logical minds and strategic thinking, qualities that are often associated with great scientists.
Our target stations are located just off Portland, so we spent a few days adjusting to shift work and familiarising ourselves with the ship. Geophysical data was collected continuously throughout our journey to help understand the bathymetry around Tasmania and Victoria, this will be continued right through to Fremantle. Day one at our first station and it was all systems go, the CTD rosette was loaded and ready to be winched off the ship to collect hydrochemistry data through the water column down to 1700 metres. The CTD collects samples at intervals through the column, directed by the Operations Room which we had the privilege of viewing and assisting the direction.
In addition to the CTD, coloured polystyrene cups were placed in an onion bag and sent with it, to showcase the increase of pressure with depth. After the CTD returned to the ship, the bongo net was put over the edge to collect plankton samples in shallow water depths (40 metres and 100 metres).
The last collection at this station was a Kasten Core, which is used to collect 3 metres of sediment below the sea floor. On top of all of this, bird and marine mammal counts were being conducted from the viewing point on the ship. We have been lucky enough to see several species of albatross, petrels, shearwaters and prions. We even saw six seals having the time of their lives hanging around the ship. Speaking of wildlife, the team of young scientists had some spare time at night to wind down. Naturally, we bonded over watching appropriate films, such as Finding Dory.
We are only at the beginning of our journey through to Fremantle and I know there is so much more to learn. I’m already so grateful for what I have experienced and I can’t wait to wake up tomorrow to see what new knowledge lies ahead.
