62 ‘U. S. COAST AND GEODETIC SURVEY 
All four stations indicate a more or less progressive rise in sea level but at a much 
slower rate than on the Atlantic or Gulf coasts. At San Diego this rise was at the rate 
of about half a hundred of a foot per year to 1930 and at a slightly greater rate since 
then. Los Angeles indicates a rise of about 0.12 foot between 1924 and 1948, or at 
the rate of 0.005 foot per year. For San Francisco the rate is 0.005 foot per year from 
1898 to 1930 and somewhat larger since then. For Seattle it was Jess than 0.005 foot 
per year up to 1930 and since then about 0.006 foot per year. 
Alaska.—For Alaska there is only one station at which continuous observations 
for more than 20 years are available, namely, at Ketchikan. For Sitka, Juneau,
