Chronometers are instruments used for measuring time, especially those designed to keep accurate time in spite of motion or variations in temperature, humidity, and air pressure. The science area housed many of the instruments used by the expedtion for their scientific work. Anemometers are used to measure windspeed. Arctic winds are strongest in winter, averaging 7 to 12 m/s (25 to 43 km/h, 16 to 27 mph), and weakest in summer, averaging 5 to 7 m/s (18 to 25 km/h, 11 to 16 mph). Windspeed recorders use paper tapes to record variation in wind speeds over time.
