摘要：	With the launch of NASA's James Webb Space Telescope last year, scientists are more convinced than ever that space goes on into infinity. Back on Earth, those who work in the dredging business are more convinced than ever that shoaling in U.S. waterways also goes on into infinity. In addition to shoaling, containerships that call at U.S. ports are getting bigger and hauling more containers, which means the ships have deeper drafts. To handle these larger ships, ports in places such as New Orleans have had to dredge their shipping channels deeper. For companies like Great Lakes Dredge & Dock Corp. (GLDD), Orion Marine Group, Weeks Marine, EJE Dredging Service, and Callan Marine, the buildup of silt and sand in navigable waters, and deepening of waterways, harbors, and ports, has created an entire industry - and one that can be very lucrative.
