  The satellite altimeters are TOPEX, Jason-1, Jason-2, ERS-1, ERS-2, Envisat, SARAL, and Cryosat. The sea surface height derived from the satellite altimeter has been very useful in the study of the ocean circulation but still is not appropriate for the oceanographic : K. N. A. A. K. Mansor, M.

On estimating the basin-scale ocean circulation from satellite altimetry. [Chang-Kou Tai; United States. National Aeronautics and Space Administration.]. Estimates of oceanic flow are currently made on the basis of space-borne measurements of the sea surface, and monitoring of the ocean interior.

Satellite altimetry and acoustic tomography are Cited by: Unfortunately, magnetic signals of ocean circulation are not jet detected from space. This manuscript proposes to use satellite altimetry as a by‐pass to generate characteristic magnetic time series of the ocean circulation.

These characteristic time series can subsequently be. The incoming and net shortwave radiation (NSW) at the ocean surface can now be estimated from satellite data with a reasonable accuracy (5–10 w/m2) for climate studies.

To determine the surface geostrophic currents (which are proportional to the slope of the dynamic topography) from satellite altimetry, one needs an accurate and independent estimate of the geoid. Cited by: Basin-scale ocean circulation from combined altimetric, tomographic and model data: and monitoring of the ocean interior.

Satellite altimetry and acoustic tomography are complementary for this quality acoustic-tomographic 2 and altimetric 3 data are now available to test the combined power of these technologies for estimating oceanic. Sea-surface height data from satellite altimetry provide a very powerful means of determining the general ocean circulation.

For oceanographic studies in which the absolute sea-surface height is required, one has to use the equipotential height of a geoid model as a reference surface. Mediterranean from satellite altimetry, satellite gravimetry and the ECCO (estimating the circulation and climate of the ocean) model.

Traditionally thought of as a slowly varying circulation, the overturning has been estimated from hydrographic sections. Using five sections at 26°N, the circulation was found to have slowed by 30% over the period – [Bryden et al., ].Cited by: Now comes the tough question of how much of the discrepancy in degree is due to geoid uncertainties.

According to Marsh et al. (), the uncertainty of GEM-TI up to degree 6 is only cm (effectively cm, ignoring spectral leakage), and cm (effectively cm) if up to degree 8. seafloor bathymetry and ocean circulation.

The shape of the ocean's surface is determined by Earth's gravity field. Bumps and wiggles in the time-averaged sea surface height measured by altimetry can tell us where the gravity field is particularly large or small [Sandwell and Smith, ]. In turn, the gravity field has been used to estimate the depth of the ocean.

Table ay and buoy pCO 2 measurements from different platforms in the GOM. These surface pCO 2 data were collected at a depth of ≤5 m over all seasons. No satellite data were found for pCO 2 μatm due to the lack of valid satellite measurements in estuaries and nearshore waters. The corresponding spatial distributions of the surface pCO 2 data are shown in Fig.

It allows for new insights into marine geodesy, ice sheet movements, plate tectonics, and for the first time provides high-resolution bathymetry for previously unmapped regions of our watery planet and crucial information on the large-scale ocean features on intra 5/5(1).

This is because the responsible orbital errors have left no traces in crossover differences and therefore can never be removed.

However, it is possible to reduce this fundamental uncertainty substantially if the record length is long enough. Its implications on observing the basin-scale ocean circulation by satellite altimetry are discussed.20 Years of Progress in Radar Altimetry Symposium.
