The 9.0 magnitude earthquake that occurred march 11, 2011 off the east coast of Honshu, Japan resulted in a debris field in the North Pacific Ocean.

Some possible marine debris types include derelict vessels, fishing nets and floats, lumber, cargo containers, and household goods. because different debris types move with currents and winds differently, the debris may be dispersed over a very broad area between Japan and the west coast of North America.

US-flag operators with ships transiting the subject area should advise such vessels to remain vigilant and to monitor all sources of available information affecting safe and secure navigation in this area.
