In brief
RV Atlantic Explorer is a twin-screw ocean vessel. It is owned and operated by the Bermuda Institute of Ocean Sciences (BIOS) in coordination with and as a part of the University-National Oceanographic Laboratory System (UNOLS) fleet. Atlantic Explorer is in compliance with US Coast Guard, UNOLS and American Bureau of Shipping (ABS) regulations as an uninspected oceanographic research vessel and is supported by the National Science Foundation (NSF). Its homeport is St. George's, Bermuda.
The ship was constructed in 1982 as a Class III ocean-going environmental research vessel. In it was known as Seward Johnson II, owned by Harbor Branch Oceanographic Institute and based in Ft. Pierce, Florida. BIOS purchased the vessel in October 2005, and modified it to better support the planned activities. This vessel replaced the previous BIOS research vessel, the smaller Weatherbird II, which had been in use since November 1989.
The most extensive modification made to the new ship was installation of a housing and a deployment station for the institute's 24-place Conductivity, Temperature and Depth (CTD) rosette package, which is extensively used for Bermuda Atlantic Time-series Study (BATS) operations.

In context
Every figure in this section is a count, a rank or a percentile over vessels actually held in this registry — not over the world fleet, which is larger. Nothing here is estimated.
At 861 gross tons, RV Atlantic Explorer is the 67,417th largest of the 84,014 vessels in this registry that report a tonnage. The median across that set is 5,994 GT, so this hull is about 7.0 times smaller than the typical vessel on record here. The largest measures 499,167 GT.
Among the 612 research / surveys held here, it ranks 359th by tonnage — larger than 26% of that group. Their median tonnage is 2,180 GT, and the largest tenth begin at 9,452 GT. The flag most often flown by this group is United States (90 ships). The yard that appears most often against it is Wärtsilä, with 36 hulls on record.
United States is the country of registry for 2,278 vessels in this directory, of which RV Atlantic Explorer is the 1,006th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (977 ships), and the median vessel measures 1,706 GT. Browse every ship flagged United States.
Narrowing to both dimensions at once, this registry holds 90 research / surveys flying the United States flag, of which 48 are larger by tonnage.
RV Atlantic Explorer was built in 1982, making it 44 years old. It is one of 1,706 hulls in this registry delivered that year, a cohort whose median tonnage is 3,592 GT; within it this ship is the 1,257th largest. Across the whole of the 1980s the registry holds 13,213 vessels, median 3,004 GT. The median build year across the entire registry is 1995.
At 52.0 m overall, RV Atlantic Explorer is 19.0 m shorter than the 71.0 m median for research / surveys on record, with a beam of 38.0 m and a draft of 11.5 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8120014 this registry holds 30 other vessels, whose median build year is 1983 and which range from 1980 to 1985. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1982.
Its IMO number, 8120014, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 1×6 + 2×5 + 0×4 + 0×3 + 1×2 = 74 — and the last digit of that total, 4, must equal the seventh digit, 4. It does, so this number is well formed.
