Oceans cover more than 70% of the Earth's surface, yet only 15% of the ocean floor has been mapped in detail. Much remains unknown, including the location of potentially hundreds of thousands of seamounts, which can be hazardous to navigation. Scientists at the University of Oxford are working with others to compile the most comprehensive analysis of the ocean floor yet.

UK population movement falls 59%, compared to -89% in March - COVID-19 Monitor

COVID-19 Engineering Maths Research

The latest data from Oxford’s COVID-19 Impact Monitor shows the January lockdown has, so far, had one third less national impact on movement than the March shutdown. The figures demonstrate that some regions are still moving at more than 50% of pre-pandemic levels, despite the tough restrictions and calls for people to remain at home.
