Partnering on the Digital Ship: Inside Denmark’s ShippingLab
When will the first fully digitized, autonomous and environmentally friendly ship be ready to sail? The answer is uncertain but the Danish Maritime Authority’s ShippingLab project aims to have most of the technical and managerial challenges solved in as little as two years from now. Tom Mulligan reports.Denmark’s ShippingLab project is a three-year initiative that commenced its work in March 2019 with the aim of developing the first fully commercially operational, fully digital, autonomous and environmentally friendly ship.
Sensors Track Gulf of Mexico's Nitrate Pulse
A new U.S. Geological Survey (USGS) report describes how advanced optical sensor technology is being used in the Mississippi River basin to accurately track the nitrate pulse to the Gulf of Mexico. Excessive springtime nitrate runoff from agricultural land and other sources in the Mississippi drainage flows into the Mississippi River and downstream to the Gulf of Mexico. This excess nitrate contributes to the Gulf of Mexico hypoxic zone, an area with low oxygen known commonly as the "dead zone." NOAA-supported researchers reported that the summer 2014 dead zone covered about 5…
