From ping signal to MH370 Wreckage

Multinational aircrafts and vessels concentrate in the southern Indian Ocean to search for the wreckage of the ill-fated flight MH370. Vessels such as Haixun 01 and Ocean Shield detected the ping signal believed to be from the black box of MH370. Ocean Shield picked up the signal again.
     Will the Joint Agency Coordination Centre (JACC) send submersibles to locate the MH370 wreckage?
