    "description": "Daily folders (11) of Simrad format (.raw) acoustic data. Echoview format (EV) template. FSS data for 6 pelagic hauls or rod and line deployments in FSS database. CTD data for 6 vertical dips. Continual thermo-salinograph data. Continual AGDS data. Go pro images for rod and line and net deployments.(MP4) Go-Pro attitude data.(CSV)\r\nOverall Objectives:\r\n\u2022\tTo investigate the use of a broadband system as a means to determine mackerel size.\r\n\u2022\tTo estimate mackerel density and abundance.\r\n\u2022\tTo study distribution of cetaceans and their relationship to mackerel shoals.\r\n\r\nSpecific Objectives\r\n\r\n1.\tCalibration of Broadband system.\r\n2.\tObtain acoustic data from mackerel using the broadband system.\r\n3.\tObtain echosounder recordings of mackerel schools and map their distribution. \r\n4.\tObtain biological samples of mackerel from schools by trawling.\r\n5.\tCalibrate Sv and TS gains on the Simrad EK60.\r\n6.\tDeploy a Go-Pro camera system with additional sensors into the mackerel schools to observe behaviour.\r\n7.\tObserve marine mammal distribution and activity during daylight hours. \r\n8.\tObtain towed hydrophone recordings of mammal vocalisation during survey transects.",
