it is flowing downwards, rather than if you have looking at nigeria or in peru, where these currents are moving upwards. these two currents are going together and flowing down along the west australian coastline. we're talking -- that's more part of the african/asian monsoonal rate to be able to better predict ocean currents, where they are going, how they affect the climate, temperature of those upper boundary currents of the ocean. so, it's a very complex structure over there. that's why there is -- and unfortunately, such an understudied region. >> eric raes, thank you so much for helping us understand this area of the ocean, one of the most remote on earth, describing the currents there for us, which could, perhaps, explain why they have not been able to locate any debris in this area, because the current could have just swept anything away. eric, thank you so much. we are covering the breaking news with this discovery of possible pings from flight 370.
