    Determination of Mass Balance of Polar Ice from Gravity

    We use satellite solutions to the low degree zonal coefficients of the Earth’s gravitational potential, J 2 through J 7, to reveal large scale f...

    MASS BALANCE OF POLAR ICE FROM LONG WAVELENGTH FEATURES OF THE EARTH'S GRAVITATIONAL FIELD

    We have used satellite solutions to the low degree zonal harmonics of the Earth's gravitational potential, and rates of surface accumulation to partially constrain, by means of repeated forward solution, the t...

    Constraints on Long-Period Sea Level Variations from Global Tide Gauge Data

    We use monthly, global tide gauge data archived at the Permanent Service for Mean Sea Level to search for: (1) the 18.6-year ocean tide; (2) the 14-month pole tide in the deep ocean and in the North Sea region...
