A massive international effort has been underway in the search for Malaysia Airlines flight 370 since the Boeing 777 lost contact on March 8. A range of resources has poured in from various countries to help in the search.

The Wall Street Journal created a graphic that breaks down the resources being used:

The graphic shows a range of sea and air vessels from 12 countries that have been involved in the search. President Obama had previously said that finding the plane is a top priority and the US would make resources available in the effort. Australian officials have also promised to continue helping in the search. China has five ships in the search area and sent additional ships there, according to the Los Angeles Times.

The search area has focused on a remote part of the southern Indian Ocean after two large objects, possibly debris, were spotted by satellite on Thursday, Mar. 20. Since then, Australia has sent several planes to search the area, but investigators have not turned up anything. Today, a Chinese satellite spotted another object, but search efforts again ended without a new discovery.

There were 12 crew members and 227 passengers on the jetliner, which was traveling from Kuala Lumpr to Beijing.
