iodp-Funded Projects

1. Millennial to centennial scale variability in the Asian summer monsoon: Foraminiferal perspective from the East China Sea

Principal Investigator: Dr Raj Kumar Singh, Assistant Professor, Indian Institute of Technology, Bhubaneshwar - 751 007

Project objectives: (i) To document distribution of benthic foraminifera assemblages from East China Sea site (ii) To understand proxy response of East China Sea site benthic and planktic foraminifera on millenial scale variability in the East Asian Summer Monsoon (ASM) during last 400 ka (iii) To find out relative sensitivity of internal and external function forces (like ENSO, solar insolation, sunspot number, orbital cycle etc.) on ASM variability and (iv) reconstruction of ASM variability since LGM using high resolution proxy records of past 20 ka. 

Time schedule: Three years

Sanctioned on: 22nd December 2014

Status: running

 

2. Mediterranean Outflow Water (MOW) paleoceanography and its impact on global climate during the last 3 MY

Principal Investigator: Prof. AD Singh, Department of Geology, Banaras Hindu University, Varanasi – 221 005

Project objectives: To reconstruct the history of MOW variability since ~ 3 Ma and to understand its dynamics; to determine global climatic significance of MOW paleocirculation; and to reconstruct history of climate variability in the last five glacial cycles on orbital scale and to evaluate linkages among MOW, North Atlantic Oscillation (NAO), ENSO and low latitude monsoonal climate.

Time schedule: Two(+1) years

Sanctioned on: 14th February 2013

Status: running

 

3.  Study of seismically induced slope failure of sediments and subsurface fluid flows in the Costa Rican Seismogenic zone using long sediment cores drilled during IODP expedition 334 (CRISP)

Principal Investigator: Dr Yateesh Vadakkeyakath, Scientist, National Institute of Oceanography, Dona Paula, Goa – 403004

Project objectives: To decipher the timing of induced slope failure and slumping of sediments due to the seismicity; to evaluate role of tectonics and fluid flow through the sediment characteristics.

Time schedule: Two(+1) years

Sanctioned on: 26th November 2012

Status: completed
