Sea level heights were recorded with a tide gauge at Fletcher’s Ice Island (T‐3) while it was aground in the Chukchi Sea at 71°55′ N lat, 160°20′ W long. Harmonic analyses of the data were made for five tidal components. The tidal hour ( M 2 ) was 9.11 at this location, in good agreement with the cotidal chart of Sverdrup (1926). Mean spring tide range was 12.5 cm. Storm surges at this location on the continental shelf had a range of about 40 cm. During relatively stationary atmospheric conditions, the storm surge heights tended to follow the inverted barometer. However, under moving pressure systems, the storm surge heights developed an asymmetry that deviated from the inverted barometer. A one‐dimensional flow model with characteristics similar to a profile through the storm provides some understanding of these asymmetric storm surge heights.
