Sea level heights wcrc rccordcd with a tide gauge at Flctchcr’s Ice Island (T-3) while it was aground in the Chukchi Sea at 71”55 ’ N lat, 160”20 ’ W long. Harmonic analysts of the data were made for five tidal components. The tidal hour ( Mz) was 9.11 at this loca-tion, in good agrccmcnt with the cotidal chart of Svcrdrup ( 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 tcndcd to follow tbc invertecl barometer. IIowcvcr, under moving prcssurc systems, the storm surge heights developed an asymmetry that dcviatcd from the inverted barometer. A one-dimensional flow model with characteristics similar to a profile tllrough the storm provides some undcr-standing of these asymmetric storm surge heights. IN’TRODUCTCON A unique opportunity for sea level studies at an offshore location was presented in
