Figure 2. Annual distribution (1937-2007) of major platform types in Release 2.5 shown as millions of reports per year. For clarity the vertical scale is truncated at 9M; years 2005-07 have 13M, 15M, and 16M total reports (not visible) in Release 2.5, respectively. The red line curve shows the Release 2.4 annual counts. Ships (mainly VOS plus some R/Vs), buoys, and oceanographic are self explanatory, Ocean (permanent) Station Vessel = OSV, Coastal-Marine Automated Network = C-MAN, ocean drilling rigs/platforms and other small entities = other, and unidentified platform types = missing.
