We just finished up work at Ocean Sciences 2020 in San Diego. Organized by AGU – the American Geophysical Union, ASLO – the Association for the Sciences of Limnology and Oceanography, and TOS – the Oceanography Society, it featured 180 eLightning talks and touch screen presentations on our iPoster platform. They covered the promises, challenges, and wonders of the world’s oceans. And they created quite a buzz at the meeting.
