Angular momentum of Arctic Ocean tides
Oceanic tidal angular momentum (OTAM) is calculated for the four major tides of the Arctic Ocean, based on the tidal elevations and current velocities from a recent two-dimensional numerical hydrodynamic model. The presented OTAM tables are meant to be complementary to other modeling studies that use satellite altimetry (which cannot observe Arctic Ocean tides because of ice cover and limited s...
متن کاملDiurnal Tides in the Arctic Ocean
A two-dimensional numerical model with a space grid of about 14 km is applied to calculate diurnal tidal constituents K1 and O1 in the Arctic Ocean. Calculated corange and cotidal charts show that along the continental slope, local regions of increased sea level amplitude, highly variable phase and enhanced currents occur. It is shown that in these local regions, shelf waves (topographic waves)...
متن کاملArctic Ocean Circulation Patterns Revealed by GRACE
Measurements of ocean bottom pressure (OBP) anomalies from the satellitemissionGravity Recovery and Climate Experiment (GRACE), complemented by information from two ocean models, are used to investigate the variations and distribution of the Arctic Ocean mass from 2002 through 2011. The forcing and dynamics associated with the observed OBP changes are explored. Major findings are the identifica...
متن کاملArctic sea surface height variability and change from satellite radar altimetry and GRACE, 20032014
Arctic sea surface height (SSH) is poorly observed by radar altimeters due to the poor coverage of the polar oceans provided by conventional altimeter missions and because large areas are perpetually covered by sea ice, requiring specialized data processing. We utilize SSH estimates from both the icecovered and ice-free ocean to present monthly estimates of Arctic Dynamic Ocean Topography (DOT)...
متن کاملInverse 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...
