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
(2) On Station Sampling and Detailed Mapping - 4 days
  • 4 DSV Alvin Dives
  • 3-4 AUV Sentry Dives, to be conducted primarily during night operations
  •  4-6 Dredge hauls, to be conducted during night operations
Part 2: Early Career Science Training Cruise

The field program is focused on Detailed Mapping and On-site Sample Collection

(1) Detailed Mapping
  • High-resolution Multibeam 
  • Shipboard, BGM-3 Gravity
  • 3-4 AUV Sentry Dives 
(2) On Station Sampling 
  • 4 DSV Alvin Dives
