R/V Oceanus Scientific Instrumentation


The National Science Foundation (NSF) Shipboard Technician Grant provides support for a suite of scientific instrumentation available for use aboard WHOI vessels. In most cases, a scientist may operate the equipment with a minimum of instruction; some instruments (e.g. sediment corers) require WHOI technical supervision. If a scientific program includes use of any of the following items, please complete the relevant portions of the Cruise Planning Questionnaire as soon as possible. The Marine Operations Coordinator will notify the appropriate contacts at WHOI and every effort will be made to provide that equipment aboard the vessel.


- Ship parameter data logging and display system (Calliope) with Ethernet, video and RS232 data distribution capability

- Navigation displays, winch readouts, meteorological readings in principal laboratory spaces- Uncontaminated salt water distribution system

- Bathymetric systems (3.5 kHz and 12.0 kHz)  
  • Knudsen 320B/R with digital data logging and EPC graphic recorder
  • Knudsen 3260 Chirp echsounder
  • Edo 323 B 12 kHz transducer
  • Array of 12 3.5 kHz transducers
- SBE 911+ Deck Unit and CTD Rosette equipped with 24 ea. 10-liter Niskin bottles (see WHOI Standard CTD Package)

- Sippican MK 21 XBT with software  
  • Hand-held and deck launchers
- RDI NarrowBand 150 ADCP
- RDI Ocean Surveyor 75 KHz ADCP

- Ashtech GPS position, ship heading & attitude sensors

- Meterological sensor system (IMET specific sensors requested seperately)

Meteorlogical sensors vs. IMET sensors
A meteorological sensor suite consisting of wind speed, direction, air temperature, humidity, precipitation, short-wave radiation and barometric pressure is provided. These sensors conform to standard forecast quality instrument requirements. For specific climate related studies, an IMET instrumentation package is available with independent data logging. For information on IMET sensors see:  IMET Sensors Defined
