A long story that I will make short. I have been Captain on the JOIDES Resolution for 5 years. However before joining the JOIDES Resolution some 19 years ago I have sailed as Captain on larger offshore fishing boats. I have worked as a Ship’s Officer since 1980 (34 years)
Foraminifera are single-celled micro (very small) planktonic animals (they eat plankton) with perforated (holed) shells made of calcium carbonate (CaCO3 i.e. chalk). Most kinds are marine (live in the ocean), and when they die, their shells form thick ocean-floor sediments.
