Today begins the fifth day of sailing and there continues to be calm water. Every day my team group begins at midnight and we perform measurements with the XBT and uCTD and sometimes CTD with the rosette. After the end of the shift, I sleep a few hours until lunchtime and then I start again the next shift. Over the course of the shift, we were surprised when garbage got stuck in the “Fish instrument”. It’s amazing what the currents transports…
I am excited because now I am working on my project. The project involves the “Foramifera and the water masses”. These organisms have a fossil record that extends from today to more than 500 million years ago. Although each foram is just a single cell, they build complex shells around themselves from minerals in the seawater. These shells have accumulated in layers of sediment below the seafloor of the open ocean and in regions where the ocean once flooded the continents for millions of years and get insight into how climate changed in the past.
