    "description": "Daily folders (19) of Simrad format (.raw) acoustic data. 19 Echoview format (EV) format analysis files. Excel biological data for 29 pelagic hauls. CTD data for 34 oblique dips. Excel data for 34 plankton tows. Continual Thermosalinograph data. Continual AGDS data.\r\nObjectives:\r\n\u2022\tTo conduct an acoustic survey to estimate the abundance and distribution of herring in the north western North Sea and north of Scotland between 58\u00ba30\u2019-62\u00baN and 4\u00baW to 2\u00baE, excluding Faroese waters.\r\n\r\n\u2022\tTo obtain biological samples for echosounder trace identification using a pelagic trawl.\r\n\r\n\u2022\tTo obtain samples of herring for biological analysis, including age, length, weight, sex, maturity, ichthyophonus infection and fat content.\r\n\r\n\u2022\tTo obtain hydrographic data for comparison with the horizontal and vertical distribution of herring.\r\n\r\n\u2022\tTo obtain plankton samples to map the distribution and abundance of zooplankton.\r\n\r\n\u2022\tTo obtain in-situ target strength data on herring using the autonomous echosounder mounted in a drop frame.",
