Hi there, After a science-packed 3 weeks on the ice sheet, the team has returned to Kulusuk, more successful than we ever expected. We accomplished the following: Drilled ice cores at three sites to measure firn density, and to take chemistry samples Installed wells at three sites for water sampling Measured firn permeability at different […]
On the next part of our journey the DC-8 traversed the tropical Pacific Ocean. I have always been deeply fascinated by this part of the atmosphere. The tropical Pacific Ocean lies over very warm water heated by the sun, and it is often considered to be the “firebox” of the atmosphere, the place where vast […]
By Eric Lindstrom Two ships in Honolulu were abuzz with action this last week preparing for SPURS-2, a detailed study of ocean salinity in the eastern tropical Pacific Ocean. The Roger Revelle, upon which all the scientific party sails, had to be loaded with many tons of scientific equipment and installations completed all over the […]
The other day I had a unique and difficult experience. I was on the tarmac at Kona International Airport, Hawaii, and I watched the DC-8 take-off, with all my colleagues, our crew and my instruments on board. This wasn’t planned, and no, I hadn’t just missed my flight. Somewhere between California and Alaska I caught a […]
Last Saturday, part of the team arrived safely in Kulusuk! Olivia, Clem and Stefan flew in two hours with Air Iceland from Reykjavik (Iceland) to Kulusuk (East Greenland). This is one of a few international airports on the east side of Greenland and also the home of our container full of camping and science equipment. […]
By Eric Lindstrom I am writing this while on a plane headed toward Honolulu to join the Research Vessel (R/V) Roger Revelle for six weeks at sea in the Pacific Ocean. It feels great to be heading to sea again. This NASA field campaign will last more than a year, with intense shipboard work near […]
We had a gently warm morning for takeoff to Hawaii, with sun peaking through the clouds. Getting above the clouds we had spectacular views of snow capped peaks. We made a missed approach at Cold Point, population 109 at the last census. Low clouds prevented us from seeing too much there visually, but through the […]
The title of this post is borrowed from Phillip Pullman’s prequel to his Dark Materials trilogy. I loved these books as a child, and by happy coincidence ended up studying for my masters at the college on which Jordan College in the novels is based. The reference to journeys northward and parallels with searching for […]
I have been looking forward to the second leg of the ATom mission since I first worked up the plan, collaborating with the others on the leadership team and with the flight operations crew from NASA’s Armstrong Flight Center. It would start in the hot, high desert in Palmdale, California, and journey to the high […]
I’m Róisín Commane, a researcher at Harvard University working with Steve Wofsy (ATom PI) and Bruce Daube (chief engineer) to measure CO2, CH4, N2O and CO concentrations during ATom. As the project evolves, I’m hoping to provide some insight into both the science we are doing and what it means to work on an aircraft […]
