[coccoliths] Special call for nannofossil paleontologists for IODP Exp 367 & 368

[Denise Kulhanek]

The International Ocean Discovery Program (IODP) is seeking scientists with expertise in sedimentology, petrology, organic geochemistry, and nannofossil, foraminifer, and diatom micropaleontology to sail on Expeditions 367/368 South China Sea Rifted Margin aboard the JOIDES Resolution.

These
 two expeditions aim to understand the mechanisms of lithospheric 
breakup at a non-volcanic rifted margin. The South China Sea (SCS) 
margin shows similarities to the hyper-extended Iberia-Newfoundland 
margins, possibly including exhumed and serpentinized mantle within the 
Continental-Ocean-Transition (COT). However, modeling studies suggest 
that there can be mechanisms of plate weakening other than 
serpentinization of sub-continental lithospheric mantle and two 
competing models for plate rupture have widely different predictions for
 the development of the SCS margin. The proposed drilling during 
Expeditions 367 and 368 will aim to determine the nature of crust within
 the COT and constrain (a) post-breakup crustal subsidence, (b) how soon
 after break-up igneous crust started to form, (c) timing of rifting, 
and (d) rate of extension.

Expedition 367 is currently scheduled from 7 February through 9 April 
2017 and Expedition 368 is scheduled from 9 April through 9 June 2017.
