Relevance of Climate Change for the Arctic Marine Biological
This Web Seminar took place on December 3, 2009 from 6:30 p.m. to 8:00 p.m. Eastern
Time. Presenting was
Dr. Rolf Gradinger
polar ecologist at the School of Fisheries and Ocean Sciences at the University
of Alaska in Fairbanks. Dr. Gradinger talked the unique properties of the Arctic
marine food web and the implications of Arctic warming on its structure.
This is the first, of four, Web Seminars sponsored by NASA, NOAA, and NSF as an
extension of the last IPY. In this program, Dr. Gradinger discussed scenarios outlining
the relevance of sea ice changes, temperature increases and altered precipitation
patterns. He gave a broad overview covering a very wide range of taxa and processes
including phytoplankton, zooplankton, and life at the sea floor as well as marine
mammals. Dr. Gradinger also discussed the implications of increased ship traffic,
resource exploration, as well as implications of Arctic warming for the connectivity
between Pacific and Atlantic Ocean.
Forty-six (46) participants were present at the live Web Seminar in addition to
the presenter and NSTA staff. Participating educators represented the states of
Alaska, California, Connecticut, Florida, Hawaii, Idaho, Illinois, Kentucky, Louisiana,
Maryland, Massachusetts, Michigan, Missouri, Nevada, New Jersey, New York, Ohio,
Pennsylvania, Tennessee, Texas, Virginia, Washington and Wisconsin. One participant
joined from countries outside of the United States: Qatar.
Seminar participants received a one year subscription to one of NSTA’s SciGuides
and a certificate of attendance was deposited into their My Transcript area in the
NSTA Learning Center for completing the evaluation form at the end of the program.
Here are some comments provided by the participants at the end of the Web Seminar:
- “I was not aware of the abiotic/biotic factors and changes occurring in this
region of Earth.”
- “Impact of web food cycle due to climate change.”
- “I always wondered how climate change was affecting the arctic. Some people
commented it was cyclical and that everything adjusts, but I wasn't confident in
those answers. This really gave perspective of what is happening and what the downsides
are to it. “
- "As a certified Biology/Environmental Science Teacher, and an informal educator
at Mingo Creek Park Observatory, I need to stay abreast of information related to
Thanks to the participants and the presenter for the learning opportunity, the interactions,
and a job well done!
