The Ocean Surface Topography Outreach Team announces a brand new product. A web-based lithograph entitled, The Legacy of Topex/Poseidon was unveiled in July and is available for downloading. The product is informally referred to as the "Topex 14-globe litho". The lithograph displays 13 years of sea-surface topography data acquired by the Topex/Poseidon satellite during its remarkable operating period. The 14th globe represents one year of Jason-1 data. The globes show the annualized sea-surface height anomalies from 1993- 2006 and clearly indicate the year-to-year changes of the ocean.

Launched in August 1992, Topex/Poseidon was the first great oceanographic research vessel to sail into space. The data acquired by its radar altimeter, operating in conjunction with its radiometer and precision orbit determining instruments revolutionized our understanding of the global ocean circulation and sea level rise, and provided important insight into the role of the ocean in global climate change.
