Aboard ship, navigation and environmental data are collected hourly and normally transferred to shore
four times daily during scheduled email transmissions. They are then processed and displayed on this web page.
The process is automatic from start to finish. The data are collected, bundled into an email, sent to shore,
and these charts and this web page are made without human intervention. All times are GMT.
