TIDAL CURRENTS, PACIFIC COAST, FOR THE YEAR 1916. 


The following special current tables for the Pacific coast in the 
vicinity of San Francisco and Puget Sound are published in order to 
make immediately available information relative to currents from 
observations of the Coast and Geodetic Survey. Further information 
will be added as rapidly as observations are available. 

In this volume the times of slack water are predicted for every 
day of the year 1916 for San Francisco Bay Entrance and for Admir- 
alty Inlet, Wash. 

These tables are followed by a list of differences, by means of which 
the time of slack water may be obtained from the daily predictions 
for a large number of other points. 

Beginning with the year 1917 these current tables will be included 
in the Pacific Coast Tide Tables, published by the Coast and Geodetic 
Survey, which furnish in a handy form, at a nominal cost of 10 cents, 
full tidal data for the Pacific coast of North America, Alaska, eastern 
Asia, and many island groups. Special attention is invited to the 
Pacific coast tide tables, as furnishing the known reliable information 
relative to tides and currents most needed by navigators, and ‘which 
are sufficient to meet the local needs of navigators for the Pacific 
coast of the United States and Alaska. 

These current tables will also be included in the General Tide Tables, 
which give the tides and other data for the entire world and which 
are furnished at a cost of 50 cents. 

Beginning with the year 1917 both of these tide tables have been 
greatly enlarged and simplified. Considerable additional informa- 
tion along tidal and current lines has been added, and all has been 
put in a form specially adapted for the use of mariners and others 
using the tables. 

Navigators and others are invited at all times to send information 
or suggestions for increasing the usefulness of the tide tables of the 
Survey to the ‘Superintendent, United States Coast and Geodetic 


Survey, Washington, D. C.”

High high waters indicate strong east-going streams, and low low waters strong west-going streams. 
a ae ordinary maximum velocity of the flood or east-going stream at the center of the channel is 3.3 knots, 
and of the ebb or west-going stream 3.4 knots.
