Cape Baleia, Caravelas, Brazil

STS054-86-001 (13-19 Jan. 1993) --- This 70mm view shows a spectacular multiple spit on the coast of Brazil, about halfway between Rio de Janeiro and the mouth of the Amazon River. Over a few thousand years, according to NASA scientists, shifting regimes of wave and current patterns piled up sand onto a series of beach ridges and tidal lagoons. The present swirls of sediment along the coast evidently were derived from beach erosion, because streams flowing into the Atlantic contain dark, clear water. Offshore, reefs and sandbanks parallel the coast. The largest is the Recife da Pedra Grande (Big Rocks Reef).
