Gravimetry from a combination of INS and GPS measurements is well known and investigated since several years. The main application is in the field of airborne gravimetry, where the results can be used to fill the spectral gap between spaceborne gravity field data (from satellite missions such as CHAMP, GRACE or GOCE) and terrestrial data available from regional or continental gravity networks. ...

A shadowing-analysis-based algorithm is modified to estimate significant wave height from shipborne X-band nautical radar images. Shadowed areas are first extracted from the image through edge detection. Smith’s function fit is then applied to illumination ratios to derive the root mean square (RMS) surface slope. From the RMS surface slope and the mean wave period, the significant wave height ...

The Norwegian Remote Sensing Experiment in the marginal ice zone north of Svalbard took place in fall 1979. Coordinated passive and active microwave measurements were obtained from shipborne, airborne, and satellite instruments together with in situ observations. The obtained spectra of emissivity (frequency range, 5 to 100 gigahertz) should improve identification of ice types and estimates of ...

The goals of this project are to utilize shipborne remote sensing to understand the scattering and attenuation process of ocean waves interacting with ice. A dedicated nautical X-band radar on a vessel would be used to follow the propagation of waves into the marginal ice zone (MIZ) and observe the attenuation and scattering of wave modes from the floating ice as well as estimate surface wind a...

Seven years of SeaWiFS and three years of MODIS observation data were used to obtain seasonal and interannual time histories of the major water color producing agents (CPAs), phytoplankton chlorophyll (chl), dissolved organic carbon (doc) and suspended minerals (sm) for Lake Michigan. Correlations of the retrieved CPAs with the coincident environmental observations are established. Episodic eve...
