Summary of Field Work: |
Starting in 2021 our objective is to deploy for two years 15 ocean bottom seismometers (OBSs) on Axial Seamount. These OBSs will enlarge the permanent 7 station seismic network in the southern Caldera to cover the entire caldera and the ends of the north and south rift. The objectives will be to record the high rates of seismicity expected in the build up to and during the next eruption so as to better understand the dynamics of the northern caldera, the interactions between the caldera faults and rifts, and search for precursory signals.
The OBSs will be deployed in summer 2021 The OBSs will be recovered and replaced on a single cruise in 2022 so as to maintain continuous monitoring The OBSs will be recovered in summer 2023 |
Summary of Facility Requirements: |
A regional class vessel with sufficient deck space for 15 OBSs and means to deploy them over the side |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
On site time is 3 days to deploy and survey OBSs and 1 day of contingency. Each OBS will take just under 3 hours to deploy and survey as per OBSIP/OBSIC guidelines (http://www.obsip.org/experiment-planning/obsip-instrument-use-policies-and-procedures/#plan) with =/1/2 hour transit in between. The OBS technicians cannot work around the clock. |
