By Ludovic Brucker We still wonder whether our campaign was successful, or fair. For sure, it was a mix of good and tough times. The pluses, making our campaign a good time: – We’re back from our field site, healthy and with all our fingers and toes! – We set up an almost perfect camp, […]

Every month we offer a puzzling satellite image here on Earth Matters. The April 2014 puzzler is above. Your challenge is to use the comments section to tell us what the image shows, what part of the world we are looking at, when the image was acquired, and why the scene is interesting. How to answer. Your answer […]

We have spent the last few weeks discussing the differences between inherent and apparent optical properties in the ocean and how we measure them. Now let’s take a moment to appreciate the information these data give us. I am sure many of you have seen satellite images of the ocean, hurricanes, etc. on the news and at other outlets. A lot of work goes into each and every one of those images and they can show remarkable things on a global scale that would be difficult to detect through fieldwork alone.
