The seasonal closure of northern ports is particularly striking in this visualization. What's really interesting is how it reveals the economic implications - not just that shipping slows seasonally, but how companies plan infrastructure investments around these natural bottlenecks. The cold-water port shutdowns create cascading effects throughout global supply chains that we rarely discuss explicitly.

It would be fascinating to see this data overlaid with commodity prices and exchange rates during those seasonal transitions. The interaction between maritime logistics and commodities trading is largely invisible to most people, but it fundamentally shapes everything from energy prices to agricultural commodity costs in ways that filter down to consumers.
