Underway Sensors

Data from Sikuliaq's underway sensors are logged by our science data acquisition system. Each sensor's data string can be found in the Format Descriptions document, located on the underway data external hard drive, given to the chief scientist at the end of each cruise.
Much of the underway sensor data can be viewed in Real-Time via TV monitors through-out the ship or your stateroom, the ship's internal website or the monitors in the computer lab.

Gravimeter

• Model: DGS AT1M

  • Specs

• WHOI PFPE 

• Location: Electronic workshop along ship's centerline, 1-12-1

Seawater Sensors

Currently Installed Instruments:

• 02 deck

  • Heitronics Infrared radiation pyrometer, Models: CT15.85 and CT09.85WT, measuring sea surface skin temperature. Photo

    • The CT15 sea surface skin temperature is corrected for reflected sky radiance with a direct input from a CT09 infrared radiation pyrometer. The CT09 is pointed skyward, orthogonal to the CT15.

    • Location: starboard side of the ship, forward of the Science Control Room (SCR), 8.8 m (29.0') above average water line.
      
      

• Bow Thruster Room

  • Sea-bird SBE 38 temperature sensor, near the Uncontaminated Seawater System intake.
    
    

• Centerboard

  • A Sea-bird SBE 38 temperature sensor and AML Sound Velocity sensor are installed at the bottom (shoe) of the centerboard.
    
    

• Main Lab Wet Wall, fed from the Uncontaminated Seawater System. Plumbed instruments, in series from manifold:

  • 1 - Two Sea-bird SBE 45 TSGs 

  • 2 - Pro Oceanus TDGP

  • 3 - Aanderaa Oxygen Optode

  • 4 - Sea-Bird ECO Triplet

    • The ECO Triplet is configured to measure Chlorophyll @695nm, FDOM @460nm and Scattering @650nm.

  • 5 - KROHNE OPTIFLUX 5000 Electromagnetic flowmeter

  • S - Sea-Bird SUNA V2 Nitrate Sensor, is plumbed with a separate line from the manifold.

  • Contact the Science Operations Manager about manifold port availability if you would like to plumb an underway instrument into the Wet Wall manifold. Depending on the data output, it may be possible to integrate your instrument(s) with Sikuliaq's science data acquisition system, given sufficient notice.

• Wet Lab sensors fed from the Uncontaminated Seawater System:

  • PC02 system

    • Air intake line is on the Foremast, 14.9m (49') above average water line.

  • Sunburst Sensors AFT-pH

  • KROHNE OPTIFLUX 5000 Electromagnetic flowmeter

Cameras

• A Bridge Cam is located inside the bridge looking forward at the bow. It is capturing a time stamped, low resolution, .JPEG photo once every minute while the ship is underway. The images are logged by our science data acquisition system. A live video stream from the camera is available on the ship's internal website and TV system.  A near-live feed is available shore-side.
