Discussion. An Investigation Into the Effects of Warmed Water From Marchwood Power Station Into Southampton Water.

Abstract

stations and the staff operating them were part of the neighbourhood in which the station was found. Work of the nature described in the Paper, which was of general value to Southampton and elsewhere, was not likely to be so successful without that element of good neighbourliness.64. It had been said that 'a little fellow feeling makes us wondrous kind'. About the year 1950 somebody brought him the rudder of a little boat which he owned, unpleasantly eaten by the gribble. There was some evidence from ports in the southern half of the British Isles that, as Professor Raymont had indicated, occasional outbreaks, very similar to outbreaks of diseases in cities, could be triggered off by unusual occurrences of temperature, importation or local change in environment. It seemed probable that those areas primarily affected needed a permanent monitoring of the conditions in harbours of the kind in question. 65. The Paper described a considerable advance in the knowledge of temperature phenomena in tidal estuaries, particularly where fresh water and salt water mixed, or rather did not mix, and there might be a temptation to feel that the job had been nearly completed. The present results, however, were hardly what the original investigation had anticipated, and he hoped that the exercise would continue indefinitely, because the further useful results which were likely to arise might equally well not be anticipated at the present time and there was still a danger of reaching premature conclusions.66. Some support for that was to be found in the fact that the Authors in Q 56 referred to 'the limited time available for survey and office work'. He was very conscious of the calls on the time of senior staff in all three participating bodies and the natural tendency of technical and professional personnel to concentrate on doing the *
