Funding Agencies: |
DOE - interagency agreement - Funded |
|
Summary of Field Work: |
High resolution imaging of sediments and water column from shelf-break to base of upper slope (approximately 150 m to 1750 m water depth) on Mid-Atlantic margin from Washington to Wilmington Canyons to encompass the area of intense upper slope seepage documented by collaborative work in 2012 and 2013. Some additional lines may be acquired on parts of margin just to the north and in Hudson Canyon. |
|
Summary of Facility Requirements: |
Ship capable of working at water depths up to ~2500 m in Mid-Atlantic slope region in late spring timeframe.
No compressor required. |
|
Summary of other requirements and comments: |
Due to expiration of 5-year Interagency Agreement, cruise must be completed by 31 May, 2015.
Due to use of some of the same USGS equipment and personnel by Jason Chaytor (USGS) on the R/V Sharp in mid-May 2015, this STR is for a ship available in April 2015.
Data quality will be jeopardized by sailing in March. Money can be returned to sponsor if that is the only scenario possible, but cruise might not be possible in an out-year, depending on sponsor's funding situation. |

Optimum Start Date:
|
4/20/2015 |
Dates to Avoid: |
Must complete cruise by 5/31/2015 due to expiration of 5-yr interagency agreement
Some of the USGS equipment is needed by Jason Chaytor (USGS) on R/V Sharp in May 2015; USGS requires at least 5 days between end of Endeavor cruise and start of his Sharp cruise
Data quality could be seriously compromised (and sponsor may not pay) by weather and sea state before early April |

Are you or any member in your science party bringing in any science equipment items which are regulated for export by the International Traffic in Arms Regulations (ITAR) and/or the Export Administration Regulations (EAR)?
|
No |
If yes, have you applied for the necessary permits through your export control office?
|
No |

Requested Start Port |
Intermediate Port(s) |
Requested End Port |

None |
Narragansett, RI, USA |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
Would be happy to work out any Atlantic port farther south than Narragansett if the ship is already working in that area. Will shorten transits. USGS can take equipment overland to any US Atlantic port.
Would have preferred to work on Sharp, which is more proximal to the operations area,but understand her schedule is full starting in early April 2015. March sea conditions are too rough to assure good data acquisition |

Explain Major Ancillary Facilities
Requirements and list description
and provider for "other" systems. |
USGS will provide: 72-channel digital streamer, birds, and related peripherals; 5 kJ sparker and S-boom sources; appropriate navigational monitoring software for this equipment
USGS will provide a CTD, which may be used to log temperature/depth profiles to the seafloor if there is down-time with the MCS equipment.
As noted above, coordination is required with schedule for Chaytor (USGS) cruise on R/V Sharp, which requires this same equipment. The USGS requires at least 5 days between the end of this cruise and the start of the Chaytor cruise, but would prefer 10 days. |
