During their fieldwork these Lamont-Doherty Earth Observatory scientists are deploying a plankton net, a [...]]]> http://blogs.ei.columbia.edu/2013/05/23/ctene-sensations-of-the-arctic-ocean/feed/ 0 http://blogs.ei.columbia.edu/2013/05/20/collecting-core-data-about-arctic-ecosystems/ http://blogs.ei.columbia.edu/2013/05/20/collecting-core-data-about-arctic-ecosystems/#comments Mon, 20 May 2013 17:53:40 +0000 Rebecca Fowler http://blogs.ei.columbia.edu/?p=36868 Our team spent most of Friday on the Arctic sea ice, drilling and sampling ice cores at our main field site. For each core collected, Lamont-Doherty Earth Observatory scientists Andy Juhl and Craig Aumack take a number of different physical, chemical and biological measurements that characterize the ice and the organisms living inside it. Some [...]]]> http://blogs.ei.columbia.edu/2013/05/20/collecting-core-data-about-arctic-ecosystems/feed/ 0 http://blogs.ei.columbia.edu/2013/05/19/what-lies-beneath-arctic-ice/ http://blogs.ei.columbia.edu/2013/05/19/what-lies-beneath-arctic-ice/#comments Sun, 19 May 2013 07:38:08 +0000 Rebecca Fowler http://blogs.ei.columbia.edu/?p=36831 On Thursday we lowered a camera into an ice borehole to get a look at the underside of the ice. In the following video, you can clearly see the algae living in the bottom of the ice due to their pigments, which they use to harvest light. These organisms are not frozen into the ice; [...]]]> http://blogs.ei.columbia.edu/2013/05/19/what-lies-beneath-arctic-ice/feed/ 1 http://blogs.ei.columbia.edu/2013/05/17/ice-capades/ http://blogs.ei.columbia.edu/2013/05/17/ice-capades/#comments Fri, 17 May 2013 10:24:53 +0000 Rebecca Fowler http://blogs.ei.columbia.edu/?p=36767 Fieldwork is exciting and inspiring, leading scientists to new ideas, places and observations about how the world works. Spring on Alaska’s North Slope provides an especially productive environment for fieldwork. When the sun never sets, it’s easy to linger in the field and the lab long into the well-lit night. Our team spent about six [...]]]> http://blogs.ei.columbia.edu/2013/05/17/ice-capades/feed/ 0 http://blogs.ei.columbia.edu/2013/05/16/settling-in-to-life-in-the-arctic/ http://blogs.ei.columbia.edu/2013/05/16/settling-in-to-life-in-the-arctic/#comments Thu, 16 May 2013 04:00:36 +0000 Rebecca Fowler http://blogs.ei.columbia.edu/?p=36672 While I arrived in Barrow, Alaska on Tuesday, Lamont-Doherty Earth Observatory scientists Andy Juhl and Craig Aumack, and graduate student Kyle Kinzler from Arizona State University, got here one week ago. They took a few days to unpack and set up their lab (everything they need to work here must be shipped to Barrow in [...]]]> http://blogs.ei.columbia.edu/2013/05/16/settling-in-to-life-in-the-arctic/feed/ 0 http://blogs.ei.columbia.edu/2013/05/14/investigating-life-in-the-ice/ http://blogs.ei.columbia.edu/2013/05/14/investigating-life-in-the-ice/#comments Tue, 14 May 2013 19:08:57 +0000 Rebecca Fowler http://blogs.ei.columbia.edu/?p=36566 Andy Juhl and Craig Aumack, microbiologists from Columbia University’s Lamont-Doherty Earth Observatory, are spending a month in Barrow, Alaska studying algae in and below sea ice, and how our warming climate may impact these important organisms. They’re investigating the factors that control the growth of algae inside of sea ice, how these algal communities are [...]]]> http://blogs.ei.columbia.edu/2013/05/14/investigating-life-in-the-ice/feed/ 0 http://blogs.ei.columbia.edu/2011/03/08/if-it-sounds-familiar%e2%80%a6/ http://blogs.ei.columbia.edu/2011/03/08/if-it-sounds-familiar%e2%80%a6/#comments Wed, 09 Mar 2011 00:46:19 +0000 Bob Crocco http://blogs.ei.columbia.edu/?p=12570 It occurred to me while reading noted historian Douglas Brinkley’s new book The Quiet World: Saving Alaska’s Wilderness Kingdom 1879-1960 that some things don’t seem to change. Brinkley’s book chronicles the efforts of the Federal government to save wild Alaska from the extraction industries, mining, timber and fisheries primarily. The notion over one hundred years [...]]]> http://blogs.ei.columbia.edu/2011/03/08/if-it-sounds-familiar%e2%80%a6/feed/ 0
