Some observations of sea ice near the shoreline were made during a weeks visit to Herschel Island, N.W.T. in January and February 1973. The observations of leads, hummocks, tidal cracks and ice strains constitute the authors initial acquaintance with ice conditions above the arctic circle. Apparent expansions and contractions in the level ice sheet of Thetis Bay give positive and negative values of strain averaging 0.00017. The latter phenomenon may correspond to relative decreases and increases in air temperature from day to day.
