High‐Resolution Numerical Modeling of Barotropic Global Ocean Tides for Satellite Gravimetry

Inverse Modeling of Ocean Tides

The principal long term goal of this project is to develop a practical, portable, nested, tidal data assimilation scheme which makes use of all available data (e.g., altimetry data, current moorings, coastal radar) to constrain barotropic and baroclinic tides (especially tidal currents) in coastal areas and shallow seas. A second long term goal is to develop more efficient methods for assimilat...

Potential and Limitations of Highresolution Satellite Imagery

The issue of commercial highresolution satellite images has found much interest lately within the remote sensing and geoinformation communities. Performance predictions and business expectations have come close to revolutionary changes in the geoinformation industry. Several missions have been planned but only one system made it successfully into orbit. Since the costs of images are high, only ...

Accuracy assessment of global barotropic ocean tide models

The accuracy of state-of-the-art global barotropic tide models is assessed using bottom pressure data, coastal tide gauges, satellite altimetry, various geodetic data on Antarctic ice shelves, and independent tracked satellite orbit perturbations. Tide models under review include empirical, purely hydrodynamic (“forward”), and assimilative dynamical, i.e., constrained by observations. Ten domin...

Nonlinear barotropic tides and bores in estuaries

The propagation of tides from the coastal ocean into shaHow estuarine waters often produces characteristic nonlinearly induced asymmetries of velocity and water level in time series. Until recently (Aubrey and Speer, 1985) a sound physical understanding of related phenomena has been difficult to obtain as flow field daia are rare. Numerical studies usually model a single estuary only; the model...
