| Kura Spit & Frontal Boundary, SW Caspian Sea: The Caspian Sea coast has changed dramatically over time, and in the past twenty years sea level has risen 2.6 m. The effects of relative fall and rise are most easily seen where topographic relief is subdued, as along the coast south of Apsheron Peninsula, Azerbaijan. Comparison of this photograph of the Kura Spit (upper right) with STS036-89-51 conveys the magnitude of change. In 1980 the large island was part of the spit. When STS036 flew in March, 1990 the spit extended ~15 km farther south toward the island. The STS101 photo reveals further erosion of the central spit, isolation of the island, and retreat of the shoreline. This area is discussed by E. I. Ignatov and G. D. Solovieva in one of eleven articles on the Caspian Sea in Dynamic Earth Environments - Remote Sensing Observations from Shuttle-Mir Missions, a volume produced by the Office of Earth Sciences and published by John Wiley & Sons (June, 2000). The light parallel bands are gravity waves in clouds along an atmospheric frontal boundary. |
