Sea Surface Temperatures (SST) as derived from the Pathfinder Sea Surface Temperature Data Set and the Along-Track Scanning Radiometer on-board the European Remote Sensing Satellite provide a unique opportunity for comparing two independent SST data sets.

Seismic activity in the region of the Aswan Dam in southeastern Egypt has likely been induced by mass loading associated with initial filling and recent high water levels in Lake Nasser.

This study examines the spatial and temporal character of sea ice floe size distribution during summer melt, important variables for understanding the summer heat and mass budgets and the distribution of heat between the vertical and horizontal ice melt. Preliminary results are presented that indicate the gradual decrease in medium size floes (1-5 km diameters) and a fairly steady maintenance of floes smaller than 1 km in diameter over the primary summer months within the central pack ice region. The latter result indicates that smaller floes continue to melt or decay rather than accumulate, indicating the importance of dynamics in affecting ice melt.
Pairs of overlapping synthetic aperture radar (SAR) pictures from 1-3 day intervals were taken coinciding with the February- March 1992 occupation of an ice station in the Weddell Sea. The resulting vectors of ice movement were used in calculating divergence, vorticity, and shearing.
This paper reviews research since 1988 into the capabilities of synthetic aperture radar (SAR) for monitoring, classification, and characterization of the Bonanza Creek Experimental Forest on the floodplain of the Tanana River and adjacent uplands.

The sea surface temperature over the Arabian Sea during the 1987-1993 monsoons will be described from Advanced Very High Resolution Radiometer measurements recorded on the National Oceanic and Atmospheric Administration polar-orbiting spacecrafts.
In this paper we present an interpretation of coarse resolution passive microwave data for 1989 and 1992 in the context of a simple model of ice-edge retreat to obtain the Nordbukta emayment growth and the formation and migration of an Odden polynya.
