Summary of Field Work: |
Up to 17 days at sea conducting sound source verification on a range of high-resolution geophysical sources that do not require IHA or other permitting. Sources would include, but not be limited to, sparkers, Chirps, multibeams, boomers, and hull-based transducers. Hydrophone arrays will be deployed to receive signals at different distances from ship. Work will be carried out at few tens of meters water depth up to 150 m. |
|
Summary of Facility Requirements: |
Clear deck space to accommodate various towed acoustic sources. Ability to pole-mount various equipment. Deck anchors and space for up to two standard (10x20) user-provided vans. Use of Knudsen 320BR for part of the cruise or capacity to accommodate user-provided 320BR transducer. Potentially require access to removable keel to install an auxiliary transducer for sound source testing. Ability to berth up to 14 scientific party members. DP is preferable, although not necessarily required. Ship with existing sound study on her hull and known quiet hull preferred. |

Optimum Start Date:
|
6/6/2016 |
Dates to Avoid: |
Would like to avoid earlier in spring (prior to 5/1) due to sea state constraints and potential deterioration of noise data (that is the point of this work). Would like to avoid after 9/1/2016 for the same reason and due to the concern about hurricanes. |

Explanation of Science Party Requirements and Technician Requirements |
The USGS will constitute part of teh science part to manage the cruise, deploy acoustic sources, and so forth. An unknown vendor will be conducting the acoustics measurements. We will require a max of 13 personnel plus the R/V Sharp technician. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
None of this should affect ship scheduling:
USGS will provide acoustic sources (except operator installed equipment). Other scientific party (acoustics vendor) will provide hydrophones and deployment technique (moored?) for detection of acoustic signals.
DP is strongly preferred. Sharp Reson MBES is high frequency compared to what is typically of concern for ocean noise, but it will be tested on this cruise.

Explain Major Ancillary Facilities
Requirements and list description
and provider for "other" systems. |
USGS and other science party would each supply a standard van.
There are specific power requirements for the sparker source (220/240 single phase generator), but USGS can discuss potential workarounds as necessary.
USGS will install 38 kHz split beam transducer in removable keel for testing on this cruise and will likely want to use the 3.5 kHz Sharp transducer as well. If both cannot be accommodated, we will likely default to the 3.5 kHz.
USGS can provide NTP server or ship can provide. Require UPS or will bring our own. DGPS feeds required in dry lab space. |
