Expedition Updates

Antarctic Expedition: 

  • The Antarctic Expedition vessel MV Ivan Papanin with 39 members including 09 Helicopter crew led by Dr S. Saini arrived in Cape Town on 04 April 2015. The two Helicopters and the vessel were de-chartered on 04 and 05 April 2015 respectively.  

 

Arctic Expedition

  • The Team selection meeting pertaining to glaciological projects for initiation during the ensuing summer phase of the Indian Arctic studies was held on 9th April 2015. 
  • Cryosphere and Climate Science: A two-member team from NCAOR visited Ny-Ålesund during this month to resume the ongoing glaciological and biogeochemical studies of the glaciers at Ny-Ålesund during the late Spring of 2015.  More than 32 line km of Ground Penetrating Radar data (by using 400 M-Hz, 200 M-Hz & 80 M-Hz frequencies) was collected to estimate the snow accumulation and ice depth of Vestre Broggerbreen glacier.  Snow sampling from Austre Broggerbreen , vestre Broggerbreen and Loverbreen glaciers was also carried out for chemical characterization of the snow.

 

Geoscience 

International Ocean Discovery Program (IODP):

  • Scientific drilling in the Eastern Arabian Sea (Laxmi Basin) based on Indian proposal commenced early April using the drilling platform JOIDES Resolution. The sixty-day long Expedition was launched from Colombo, Sri Lanka with 30 scientists from various countries including 12 from India, on board. The expedition aims to recover long and continuous sediment cores from the sub-seafloor to understand possible links between Asian Monsoon and the mountain building processes of the Himalaya. As on date,  drilling is in progress at site IND-03C, and a total depth of  ~1020 mbsf has been reached.

Delineation of the outer limits of the Indian continental shelf:

  • The sixth leg of ongoing seismic surveys commenced from Port Blair on 05-04-2015 and as on date, 1912.60 lkm of seismic reflection data has been collected from the western Andaman sector. 

EEZ Program:

  • Completed evaluation of the bids received for development of Marine Geoscientific Database and short listed a firm. Technical discussions and financial negotiations is in progress.
