Figure 2. Annual distribution (1748-2014) of major platform types in Release 3.0 (and total) shown as reports per year (logarithmic scale). Ships (mainly VOS plus some R/Vs; and prior to ~1888 hidden by the R3.0 curve), buoys, oceanographic, coastal, and tide gauge 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 (note: most are probably early ship reports).
