Feel free to change the height You can see movements of the global merchant fleet over the course of 2012, overlaid on a bathymetric map. You can also see a few statistics such as a counter for emitted CO2 (in thousand tonnes) and maximum freight carried by represented vessels (varying units). You can pan and zoom in the usual ways, and skip back and forward in time using the timeline at the bottom of the screen. The controls at the top right let you show and hide different map layers: port names, the background map, routes (a plot of all recorded vessel positions), and the animated ships view. There are also controls for filtering and colouring by vessel type. The merchant fleet is divided into five categories, each of which has a filter and a CO2 and freight counter for the hour shown on the In some cases this is because there are ships navigating via can*ls or rivers that aren’t visible on the map. Generally, though, this effect is an artefact of animating a ship between two recorded positions with missing data between, especially when the positions are separated by a narrow st*ip of land. We may develop the map to remove this effect in the future.. WHY ARE THERE FEWER SHIPS VISIBLE IN THE FIRST PART OF THE YEAR? Unfortunately the data we are using for the map is incomplete for the first few months of the year: roughly January to April. UCL EI took data showing location and speed of ships and cross-checked it with another database to get the vessel characteristics, such as engine type and hull measurements. With this information they were able to compute the CO2 emissions for each observed hour, following the approach laid out in the Third IMO Greenhouse Gas Study 2014. Kiln took the resulting dataset and visualized it with WebGL on top of a
