ADMIRALTY TIDAL STREAM ATLAS AND CO-TIDAL CHARTS
Thames Estuary


This atlas contains 13 charts showing tidal streams at hourly intervals commencing 6 hours before HW Sheerness and ending 6 hours after HW Sheerness. It also includes 6 charts showing Spring and Neap Range Factors and High and Low Water Time Differences. The times of HW Sheerness and other details of the prediction for this port are given in NP201, Admiralty Tide Tables Vol.1, which is published annually. NP201 also gives tidal predictions for a number of ports and tidal stations in the area covered by this atlas.
On the tidal streams charts the directions are shown by arrows which are graded in weight and, where possible, in length to indicate the approximate rate of the tidal stream. thus -> indicates a weak stream and --> indicates a strong stream.
The figures against the arrows give the mean neap and spring rates in tenths of a knot, thus: 19,34 indicates a mean neap rate of 1.9 knots and a mean spring rate of 3.4 knots. The comma indicates the approximate position at which the observations were obtained.
