Science objectives

The Expedition is broken into 2 phases. 

(1) OASIS Pt. 2
The first 4-days of science will be utilized to complete the objectives of the 2016 OASIS Expedition to the 8 20N Seamounts flanking the East Pacific Rise, north of the Siqueiros Fracture Zone. 

(2) Early Career Science Training Cruise
The second 4-days of science will be conducted at the 9 50N potential eruption location on the East Pacific Rise. We will spend 4 days mapping and characterizing the 9 50N segment to determine whether a recent eruption has occured. 

Science Activities

Part 1: OASIS, 8 20N Seamounts

The field program has two main components: Underway Geophysics and On-site Sample collection and detailed mapping. 

(1) Underway Geophysics - 1 North-South line on our way to the first OASIS station.

• High-resolution Multibeam (need optimal swath width)
• Shipboard, BGM-3 Gravity

Pre-cruise planning meeting: Teleconference

Media personnel on board: Video, Writer
Ken Kostel will be joining the cruise and handling media.
