Summary of Field Work: |
This project complements, integrates, and extends ongoing research efforts at the Hikurangi subduction zone offshore New Zealand by providing 1) continuous records of fluid flow rate and composition over the time frame of expected slip (~ 2 yr); 2) information on the present background state and potential locations of past fluid flow; and 3) comparative data between the northern and southern sections of the margin. We propose a nested approach of surface ship operations followed by ROV Jason surveys and benthic fluid flow meter deployments. At each fault target along the margin, we will conduct a multi beam sonar survey, pogo heat flow measurements (OSU violin probe), and piston coring. Based on the results of the multibeam surveys and heat flow, ROV Jason will be deployed for 3 days to conduct reconnaissance video, multibeam surveys, heat flow measurements (with Jason heat flow probe), collect push cores, and deploy the fluid flow meters. After the flow meters are deployed, Jason will be recovered and would undergo maintenance for ~3 days while multibeam mapping, heat flow measurements, and piston cores are collected in the next target area upslope. |

Summary of Facility Requirements: |
Global class vessel with dynamic positioning and multibeam sonar
Oregon State heat flow probe
OSU coring facility, ship capability to deploy piston cores
DSV Jason with Reson 7125, jason heat flow probes, push cores, elevators |

Optimum Start Date:
|
2/1/2019 |
Dates to Avoid: |
Avoid southern hemisphere winter, fall, and early spring due to inclement weather. Prefer expedition to be in austral summer/early fall. Start date on or after Jan 1, 2019 preferred to ensure instruments are fabricated/refurbished in time for expedition and to ensure enough time for pre-expedition preparations and project management meetings |

Short Description of Op Area
for use in schedules: |
New Zealand |
| Description of Op Area: |
We will be conducting our work off the east coast of the north Island of New Zealand. The northern portion of our study area is the continental slope offshore Gisborne at depths ranging from 200-3000 m. The southern portion of our study area is the continental slope offshore Wellington spanning water depths of 200-3000 m. Length of northern transect ~21 nmi, length of southern transect ~29 nmi |
| Op Area Size/Dia.: |
Distance between two transects = 210 nmi |
