Ile de Sein is currently off the west coast of Africa heading north, probably to pick up equipment from Phoenix.
ILE DE SEIN - 9247039 - Vessel's Details and Current Position
Of perhaps more interest is this from the BEA:
The team on board the Alucia will complete vehicle operations on Friday. The vessel will leave the search area on Saturday 9 April and should reach the port of Suape (Brazil) on the morning of Tuesday 12 April.
This suggests either:
a.) WHOI is pausing its mapping and photography, and will resume after photos are interpreted, or when the Ile de Sein is enroute to the location;
b.) WHOI has photographed the recorders, or where they are likely to be, and thus there is no need for further photography at this time.
