I have always wanted to visit Greenland, the “ground zero” for climate change. Its ice cap rises more than 3,200 meters (2 miles!) above sea level and it holds so much ice that if it all melted, the height of sea level would rise by 7 meters (23 feet). The landscape is stark and inhospitable […]
By Eric Lindstrom I figured I would go off topic today and discuss a disturbing observation by someone who has spent more than half a lifetime going to sea. This is my personal opinion and does not reflect any policy or perspective of NASA. However, those of you on land really need to know that […]
As we prepare for our last flight in ATom-1, I’ve been reflecting on what I should do differently next time around as we begin preparation for ATom-2, which will start uploading in December 2016 for flights starting in January 2017. Packing less “stuff” I’m a bit of a girly girl who likes her comforts. But […]
By Eric Lindstrom The focus of SPURS-2 is the upper ocean and the fate of rainwater. However, in order to study the top of the ocean one needs to know what is going on deeper down. The beauty of SPURS-2 is not skin-deep! SPURS-2, like many prior physical oceanography experiments, requires a basic background and […]
ATom-1, the first of four ATom deployments over the next few years, is about to wind down. We’ve covered over 60,000 km and flown all the way around the world, but unlike the Jules Verne classic, it took us only 24 days (and not 80) to make it back to Palmdale, California. I managed not […]
By Eric Lindstrom What do Leonhard Euler (1707-1783) and Joseph-Louis Lagrange (1736-1813) have to do with SPURS-2? How do we have two experiments going on simultaneously honoring the work of these famous mathematicians? Two frames of reference have taken their names from these 18th century mathematicians. In science, including oceanography, when we make measurements of […]
As the first phase of the ATom project draws to a close, I am still surprised at just how far the influence of land, and fires in particular, can travel through the atmosphere. Most of the time, the influence of land (and pollution that people generate) can only be seen a few miles from shore. […]
The ATom mission is the first to traverse the whole lengths of the Atlantic and Pacific Oceans while making atmospheric measurements from the ocean surface to high altitudes. When we planned ATom, one idea was to compare pollution impacts between the oceans. I expected that human activities would have much greater influence in the Atlantic, […]
For SPURS-2 we are installing three moorings that will stay in place for over a year. Our moorings are arrays of instruments dangling from a surface floatation and anchored at the bottom. The moorings eventually will be recovered by R/V Thompson in September or October 2017. They will be recovered by using a release mechanism […]
