Galway Bay Observatory DeploymentJuly2018-xxxx

This is the third deployment of the Galway Bay Observatory having been deployed using the Granuaile vessel in July 2018. Prior to this deployment the Observatory was modified with new Cabling drums and an extended frame. The SmartBay Observatory in Galway Bay is an underwater observatory which uses cameras, probes and SENSORS to permit continuous and remote underwater monitoring. It was installed in 2015 on the seafloor 1.5 km off the coast of Spiddal, Co. Galway, Ireland at a depth of 20-25 m. Underwater observatories allow ocean researchers unique real-time access to monitor ongoing changes in the marine environment. The Galway Bay 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 Galway 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. The Observatory is equipped with a suite of SENSORS, these include: Acoustic Doppler Current Profiler (ADCP) — Teledyne RDI Workhorse Conductivity-Temperature-depth (CTD) sensor probe — Idronaut Ocean-Seven 304 plus Acoustic data that has been collected from the Galway Observatory site using an icListen HF Smart hydrophone Video data is streamed in near-real-time from the observatory and also available for download. A WetLabs ECO-FLNTU is installed on the observatory infrastructure.
