Seasonal variation in sea level in the Pacific Ocean during the International Geophysical Year, 1957-1958

Abstract

Seasonal variations in sea level derived from IGY measurements are described and compared with those previously published. These measurements confirm the earlier descriptions, which were baaed on observations from gauges attached mostly to continental coastlines. That is, in low latitudes in each hemisphere, sea level is high at the end of summer. There is a zonal band of high sea level from about the Equator to 40° N in September while in comparable southern latitudes sea level is low...
