In context
Counts over companies and vessels actually held in this directory — not over the world fleet, which is larger. Nothing here is estimated.
With 3 vessels attributed to it here, Lamont–Doherty Earth Observatory is the 262nd largest of the 965 operators in this directory that hold at least one ship on record, against a median of 2 across that group. That is a count of individually identified hulls, not the company’s published fleet size — the two are different measurements and both are shown above where available.
United States is the country of registration for 144 commercial operators in this directory, among which Lamont–Doherty Earth Observatory ranks 25th by ships on record. Between them those companies hold 435 vessels here. 1 of them carry a published container-capacity ranking. See every operator registered in United States.
Founded in 1949, Lamont–Doherty Earth Observatory is 77 years old. This directory holds 79 operators founded within five years either side of that date, whose median fleet on record is 1 ships. The median founding year across all commercial operators here is 1966, and the oldest on record dates to 1514.
