The special issue of Ocean Dynamics published papers presented at the 2010 International Workshop on Modeling the Ocean (IWMO), which was held at Old Dominion University in Norfolk, VA, US, from May 24-26, 2010. Two important topics highlighted at the event were international collaborations and involvement of young scientists. IWMO organized a special session for the Outstanding Young Scientist Award competition to encourage the participation of young scientists. Participants from more than 15 countries attended the meeting, including attendees from Europe, North and South America, Asia, and Australia. The meeting was also extensively covered by the local media due to the BP oil spill in the Gulf of Mexico that happened before the event.
