35 YEARS AGO – 1977
The Port of Busan, South Korea planned a $112 million project to extend its container wharf by 700 meters, which would require dredging the berths to 12.5 meters, plus rehabilitation of two existing piers and two wharves.

The National Wetland Inventory was launched to identify wetlands in the U.S., its territories and possessions. President Jimmy Carter told Congress that the total wetlands in the U.S. had been reduced 40 percent since the 1950s and were being lost at the rate of 300,000 acres per year.
