First introduced on board the Half Moon in 2007, the Deck Log is a record of river science readings maintained from one Voyage of Discovery to the next.
Each half hour during our operating day, the student crew work in tandem to collect and record the current date and time, the ship's position (using latitude & longitude), the air and water temperature, wind speed and direction, and relative humidity levels. On this voyage, we also tracked air temperature and relative humidity overnight as part of our Anchor Watch duties.
