Dugdale, R.; Wilkerson, F.; Halpern, D.; Chavez, F.; Barder, R., 1993, "Remote Sensing of Seasonal and Annual Variation of Equatorial New Production: A Model for Global Estimates", https://hdl.handle.net/2014/35376, Advances in Space Research, JPL Open Repository
Sea-surface temperatures (SSTs) are strongly correlated with surface nitrate concentrations in coastal upwelling regions. Upwelling also occurs in the equatorial Pacific; correlations between temperature and nitrate concentration are strong. The University of Miami weekly average... |

Sovers, O., 1993, "Vertical Ocean Loading Amplitudes From VLBI Measurements", https://hdl.handle.net/2014/35464, UNKNOWN, JPL Open Repository
Vertical ocean loading amplitudes are determined by analysis of IRIS geodetic VLBI data. Vertical ocean loading amplitudes can thus be inferred from VLBI data at a level which improves the overall model, but detailed assessment of individual tidal components is presently obscured... |

Peter, M., 1993, "A Parametric Approach for the Geocoding of Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) Data in Rugged Terrain", https://hdl.handle.net/2014/35509, UNKNOWN, JPL Open Repository
A geocoding procedure for remotely sensed data of airborne systems in rugged terrain is affected by several factors: buffeting of the aircraft by turbulances, variations in ground speed, changes in altitude, attitude variations, and surface topography. |
