Summary: | Atmospheric carbon dioxide concentrations have been rising for the past 200 years, and started increasing at a faster rate during the last 60 years. The world's oceans act as a reservoir for large amounts of CO_2. How they will respond to increasing atmospheric concentrations of carbon dioxide is unknown. It is imperative that the movement of CO_2 between the air and the ocean is unequivocally understood. Sea-water pCO_2 concentrations were measured in the north-east Atlantic Ocean off the island of Ireland, using a Pro-Oceanus CO_2 Pro pCO_2 instrument. The sensor was installed on the R.V. Celtic Explorer during 2010. The accuracy of the instrument was examined by bench-marking the sensor through a series of methods. Once completed, pCO_2 data collected by the instrument was analysed. CO_2 concentrations in the atmosphere remained stable throughout the year, while sea-water CO_2 concentrations varied on an seasonal basis. They were highest during the spring and winter months, whilst lowest during the summer ... |
