Excel biological data for 16 pelagic hauls. CTD data for 27 vertical dips. \r\nObjectives:\r\n1.\tTo conduct an acoustic survey to estimate the abundance and distribution of mackerel in the northern North Sea (ICES division IVa).\r\n\r\n2.\tTo obtain samples of mackerel for biological analysis, including age, length, weight, sex and maturity.\r\n\r\n3.\tTo determine the species composition and target strength of fish in schools using the autonomous echosounder and video rig.\r\n\r\n4.\tTo make video observations of the multi-sampling pelagic trawl with the RCTV.",
