Visualizing California's stunning shipping gridlock
CNN
Cargo ships have been circling off the ports of Los Angeles and Long Beach, waiting to offload critical household goods and manufacturing supplies.
To visualize the recent supply-chain gridlock, CNN used location data transmitted by each container ship and collected by MarineTraffic.
When animated in a time-lapse video, dozens of vessels can be seen maneuvering in holding patterns 10 to 20 miles offshore. Another group of ships is moored closer to shore. Container ships move inland to the port only occasionally.
