UK Admiralty Tidal Stream Atlases around the British Isles (1973-2005)

Twenty atlases show diagrammatically, with the use of arrows, the tidal streams in
parts of north-west Europe at hourly intervals. Each diagram is referred to the time of
high water at a selected standard port, and a method is included for interpolating or
extrapolating the rate of the stream according to the range of the tide at the standard
port. The atlases are drawn using all the available tidal stream data. They refer only
to the upper ten metres of the water column, and are thus intended to show the likely
effect of the tidal streams on a typical sea-going vessel. The data are the same as the
tidal stream data given on large-scale Admiralty charts, but the diagrammatic display
shows the general movement of the water more effectively.

本数据集包含二十幅海图，以图形方式，利用箭头标记，按小时间隔展示了西北欧洲部分地区的水流状况。每幅图均参照所选标准港口的高潮时刻进行标注，并包含了一种根据标准港口潮位范围进行水流速度内插或外推的方法。这些海图是基于所有可用的潮流数据绘制的。它们仅涉及水体上层十米的高度，旨在展示潮流对典型航海船只可能产生的影响。这些数据与大型海军部海图上提供的潮流数据相同，但图解展示水流的总体运动更为直观。
