Utilizing the US Nationwide Oceanic and Atmospheric Affiliation’s Marine Cadastre software, you’ll be able to obtain 16 years of detailed each day ship actions, in addition to “transit rely” maps generated from a 12 months’s price of information displaying every ship’s collected paths. The info is collected completely from ground-based stations alongside the US coasts.
I downloaded all of 2023’s transit rely maps and loaded them up in geographic data system software program referred to as QGIS to visualise this 12 months of marine visitors.
The maps are summary and electrical. With landmasses eliminated, the ship traces resemble long-exposure pictures of sparklers, high-energy particle collisions, or strands of fiber-optic wire.

Zooming in on these maps, you would possibly see unusual geometric patterns of excellent circles, or strains in a grid. A few of these are fishing grounds, others are scientific surveys mapping the seafloor, and others symbolize boats going to and from offshore oil rigs, particularly off Louisiana’s gulf coast.
Hiding in plain sight
Having a worldwide, near-real-time system for monitoring the exact actions of all ships at sea feels like an ideal innovation—until you’re making an attempt to maintain your ships’ actions and cargoes secret.
