1. Upside-down ice chimney

    00:29

    from AndrewJuhl / Added

    This short clip shows an upside down chimney of ice found underneath the sea ice of the Chukchi Sea near Barrow Alaska in spring 2012. At this time there was a lot of surface melting of the ice layer going on and water was flowing through the ice into the water underneath. The chimney of ice that formed was about 10 cm across. We speculate that the water directly under the ice was relatively fresh and warm (warmer than the ice). The water draining down through the chimney must have been colder (and possibly also saltier) than the underlying water, because it was clearly sinking. As the cold water sinking down hit the underlying water, it cooled it enough to freeze, forming the chimney of ice around the sinking flow.

      This video provides an overview of the work we do related to the life found inside and related to sea ice. We do scientific research on algae and other organisms that live inside of sea ice and we try to understand the role of this unique community of organisms in the larger Arctic food web.

          This is a compilation of underwater videos from under Arctic sea ice in the Chukchi sea near the northern coast of Alaska. It shows the development of algal blooms inside the ice and how the algae are released into the underlying water as the bloom declines. The video also shows how different the progression of the algal bloom can be from one location to another, even if they are only separated by a few hundred meters.

          • Collecting Plankton From Under the Sea Ice

            02:19

            from AndrewJuhl / Added

            This video shows how we collect samples of plankton found in the Arctic under sea ice. We do scientific research on algae and other organisms that live inside of sea ice and we try to understand the role of this unique community of organisms in the larger Arctic food web. For example, we are interested in whether plankton under the ice are feeding on algae and other materials released from the ice. In turn, the plankton are connected to larger organisms. Local people, like our Bear Guard Arne, understand these connections and their importance.

            • Ice Core Drilling

              04:07

              from AndrewJuhl / Added

              This video shows how we collect samples of sea ice to study the microbiology of the organisms found inside the ice by drilling out an ice core. The work shown here took place in spring 2012 on the frozen Chukchi Sea near Barrow Alaska. We drill out the ice core, usually in several segments because it is so thick, then we measure the ice temperature, and cut it into manageable sections for further analyses back at the lab. Near the end of the clips is demonstration of the porosity of sea ice, which is very different from the freshwater ice most people are used to. The fact that sea ice is porous is key to understanding how microorganisms can live inside the ice. Porosity means that there is habitable space with liquid water inside the ice where specialized organisms can thrive.

                  http://GreatWhiteCon.info/broken - Here at Great White Con Ivory Towers we've received a couple of letters from The Daily Telegraph recently, both signed Robert Winnett, Head of News. Here's an extract from one of them: "In reply to your enquiry, the Telegraph's policy is to correct clear inaccuracies once we are alerted to them - and in appropriate cases update articles on our website". This is yet another alert for you Robert. There was no "reputable evidence... to show an unbroken ice sheet more than half the size of Europe already stretches from the Canadian Islands to Russia's northern shore" on September 8th 2013. This video discusses a variety of sources of both reputable and disreputable evidence! The music is "The Hanging Cloud" by "Foales Arishes" who are based in Devon (as the name suggests!) from the charity compilation album "Water Connects Us": http://Water-Connects-Us.org Reputable evidence: Original AMSR2 microwave images by the University of Hamburg: ftp://ftp-projects.zmaw.de/seaice/AMSR2/ Vilkitsky Strait video by Tara Expeditions: http://oceans.taraexpeditions.org/ Arctic sea ice extent video from NASA: http://www.nasa.gov The OBuoy #7 webcam - http://obuoy.datatransport.org/monitor#buoy7/movie Disreputable evidence: The NASA video is also reproduced online by The Telegraph, where it is currently mistitled "Nasa animation shows Antarctic ice cap fluctuations": http://www.telegraph.co.uk/earth/environment/climatechange/10339674/Climate-change-report-Nasa-animation-shows-Antarctic-ice-cap-fluctuations.html

                    http://GreatWhiteCon.info/broken - Amongst other things an animation revealing how the Arctic sea ice concentration and extent changed between September 13th and September 27th 2013. The 2013 NSIDC minimum extent of 5.099 million km² occurred on September 13th. As you can see, the sea ice in the Arctic has many holes and cracks in it, and lots of open water around it. It is not therefore an "unbroken sheet that already stretches from the Canadian islands to Russia's northern shores", as maintained by David Rose in the Mail on Sunday edition of September 8th. On the evening of September 28th the Mail Online published a "corrected" version of that article, replacing the ludicrous original numbers with those calculated by The Great White Con. However they contrived to continue The Con by blaming their error on an NSIDC "typo" - http://GreatWhiteCon.info/2013/09/the-mail-makes-modest-amends/ Also discussed in the video is the recent IPCC AR5 Working Group 1 meeting in Stockholm - http://econnexus.org/ipcc-say-human-influence-on-the-climate-system-is-clear/ The Arctic Sea Ice Forum - http://forum.arctic-sea-ice.net/ The OBuoy #7 webcam - http://obuoy.datatransport.org/monitor#buoy7/camera The voyage through the Northwest Passage of the MV Nordic Orion - http://econnexus.org/the-northwest-passage-is-open-for-business/ The Arctic circumnavigation by the yacht Tara - http://econnexus.org/tara-reaches-open-waters-of-lancaster-sound/ and finally some beautiful Central Arctic Art - http://greatwhitecon.info/2013/09/central-arctic-art/ The music is "Bruce Willis" by Bristol band "ICYFH" from the charity compilation album "Water Connects Us": http://Water-Connects-Us.org Original AMSR2 microwave images by the University of Bremen: http://www.iup.uni-bremen.de:8084/amsr2/ Arctic sea ice extent data from NSIDC: http://nsidc.org/arcticseaicenews/charctic-interactive-sea-ice-graph/
