attribute	NC_GLOBAL	summary	String	The SmartBay Observatory in Galway Bay is an underwater observatory which uses cameras, probes and sensors to permit continuous and remote live underwater monitoring. It was installed in 2015 on the seafloor 1.5km off the coast of Spiddal, Co. Galway, Ireland at a depth of 20-25m. Underwater observatories allow ocean researchers unique real-time access to monitor ongoing changes in the marine environment. The SmartBay Observatory is an important contribution by Ireland to the growing global network of real-time data capture systems deployed in the ocean. Data relating to the marine environment at the SmartBay Observatory site is transferred in real-time through a fibre optic telecommunications cable to the Marine Institute headquarters and then made publically available on the internet. The data includes a live video stream, the depth of the observatory node, the water temperature and salinity, and estimates of the chlorophyll and turbidity levels in the water which give an indication of the volume of phytoplankton and other particles, such as sediment, in the water. Maintenance take place on the observatory every 18 to 24 months.This dataset comprises of processed acoustic data that has been collected from the SmartBay Observatory using an icListen HF Smart Hydrophone – a digital hydrophone that processes and stores acoustic data. The dataset comprises of processed data, collected from the SmartBay Observatory since its installation in 2015. The wide frequency range hydrophone is installed on a separate lander approximately 30m away from the EMSO Smartbay Cable End Equipment Node in Galway Bay in approx. 25m depth of water at 53 degrees 13.640'N 9 degrees 15.979'W.
