Integrated coastal observations provide information on the ocean in near-real time and help to understand oceanic processes and place them in a climatological context. This presentation is based on data collected in Western Australia using IMO infrastructure. The coastal observation system includes a number of platforms including ocean gliders, ocean Radar, mooring arrays supplemented by satellite imagery. Integration of the oceanographic data sets from these observation platforms reveal a number of important processes and phenomena related to fisheries. The main area of interest is located in the south-west of Australian continental shelf and slope regions offshore Fremantle extending northwards to Jurien Bay. Within this region there important topographic features such as the Rottnest Island and Perth Canyon and the circulation is dominated by the southward flowing Leeuwin Current (LC) with the northward flowing Leeuwin Undercurrent (LU) beneath the (LC) and the wind driven Capes Current (CC) located on the shelf, particularly during the summer months. The interaction between the LC and CC generate eddies which are generate high primary production. Data collected over the past few years from the observation array indicate year to year changes in the Capes Current an important conduit for Australian salmon migration. For example, during early 2016 high numbers of salmon were found in the Perth metropolitan region which could be related to the strong southerly winds experienced during the El Nino year resulting in a strong Capes Current and associated upwelling. Similarly, frontal system between the Ningaloo Current and coastal regions between North-west Cape and Dampier is an area of numbers of fish species.
