RV Roger Revelle is a Thomas G. Thompson-class oceanographic research ship operated by Scripps Institution of Oceanography under charter agreement with Office of Naval Research as part of the University-National Oceanographic Laboratory System (UNOLS) fleet.[2] The ship is named after Roger Randall Dougan Revelle, who was essential to the incorporation of Scripps into the University of California San Diego.

Construction and characteristics

Roger Revelle was built by Halter Marine Inc., Gulfport, Mississippi. She was laid down on 9 December 1993 and launched on 20 April 1995. She was delivered to the U.S. Navy 11 June 1996, as RV Roger Revelle (T-AGOR-24), a Thomas G. Thompson-class oceanographic research ship. Her maiden voyage was from Gulfport to San Diego, California, the following month.[3] She is a sister ship to the RV Thomas G. Thompson (UW), NOAAS Ronald H. Brown (NOAA) and RV Atlantis (Woods Hole), all built upon the same design.

The Roger Revelle underwent a $60 million refit between 2019 and 2020, where over six miles of cable were replaced.[4][5] The refit overhauled the power systems, ballast management, bow thruster (to a new retractable ZF thruster), refurbished the A-frame, and added a scientific gondola. The refit is estimated to add 15 years of operational life to the ship (until 2035).[6]

Data acquisition sensors and processing systems

[edit]

As of 2014, the ship comes standard with these set of Oceanographic sensors; with provisions, space, and modularity to add a variety of other scientific sensors and equipment.

Computing environment

[edit]

Shipboard computer systems consists of a cluster of Linux (CentOS) servers capable of up to 20 Terabytes of available and expandable cruise data storage in RAID6 configuration. The cluster provides email, intranet, NAS, DHCP, proxy, SAMBA, Active Directory, data processing, and data procurement services. Internet is provided using a combination of UNOLS-designed proprietary satellite system (C-Band), shore cellular network (3G, 4G/LTE), and/or Inmarsat FleetBroadband (L-Band). In addition to the cluster, there is a wide array of data acquisition computers hooked up to a modular display array. All live processed data from the ship's standard set of acquisition systems is displayed on the array, and provide live feedback of the ship's underway data. There are repeating displays in the main lab, and hydro lab that shows MET and navigation data.

The various Windows, Linux, and Mac acquisition machines perform data acquisition, archiving and processing functions on many of the permanently installed data collection systems. All data is centralized in the cluster.

Associated cruises

[edit]

The Roger Revelle's first research cruise was for the 1996 CalCOFI cruise, which she commonly undertakes on an annual basis.[3]

Roger Revelle and her sister ships are required for maintenance on the OOI Regional Cabled Array off the west coast of the United States.[10][11] The Revelle is capable of deploying a 36-niskin rosette and has participated in several sections of the NSF GO-SHIP and GEOTRACES hydrography programs.[12] She is large enough to accommodate for an ROV and associated equipment, thereby also making her capable of engineering cruises and exploration for hydrothermal vents.[13][14] This included portions of the NOAA vents program (1980 - 2013).[15][16]

With a large operational range, she is used to deploy floats (ARGO, GO-BGC, SOCCOM, etc.) in remote areas.[17][18]

In December 2006, Roger Revelle departed from SIO's Nimitz Marine Facility in Point Loma and embarked on a six-year journey around the globe, stringing together 86 distinct missions.[19] When finally returning to its home port, an estimated $300,000 was spent on upkeep maintenance.

In 2018, the Roger Revelle and Sally Ride were used to research zooplankton responses to phytoplankton blooms (and associated impacts on the biological pump), particularly in relation to Salps and climate change.[20] The Roger Revelle was used to deploy the large MOCNESS net system, collecting biological samples from multiple depths.
