NEW ORLEANS (AP) - A New Orleans rabbi is wondering when the public's mind will refocus on what happened in the Gulf of Mexico a year ago today.

Rabbi Edward Cohn says "our souls are slumbering in moral indifference." He spoke as a handful of environmentalists and religious leaders gathered to remember the 11 oil rig workers who died in the Deepwater Horizon explosion that sent 206 million gallons of oil into the Gulf.

Those taking part in the ceremony also called for steps to prevent another environmental catastrophe.

The sunrise ceremony in New Orleans was one of several events planned today to mark the anniversary.

Family members of some of the men who died have accepted an invitation from rig owner Transocean to fly by helicopter over the spot where their loved ones were lost. Their bodies haven't been recovered.

Other vigils are scheduled in Louisiana, Mississippi, Alabama and Florida.
