The Port of Long Beach resumed full cargo-handling operations Thursday, Aug. 28, after a lessening of storm surges from Hurricane Marie that had battered south-facing piers and interrupted the loading and unloading of four vessels a day earlier. With swells down to 8 to 10 feet, from a peak of 15 feet or more on Wednesday, Total Terminals International on Pier T went back to work on two Mediterranean Shipping Co. container ships. Crescent Terminal on Pier F also resumed the unloading of Mercedes-Benz automobiles and wind towers from two vessels.
