21 and 28 July 2008 - Join PolarTREC/NOAA TAS teacher Jillian Worssam and the research team aboard the USCGC Healy in the Bering Sea for a real time Live from IPY! event. Learn more about the Bering Ecosystem Study and interact with researchers doing important climate change research.

Jillian Worssam grew up in suburban Connecticut but considers herself a child of America. Ms. Worssam has traveled to every state, and it was through this exploration that she fell in love with nature and became fascinated with the diversity of all living systems. After attending an alternative outdoor educational school in Vermont, she moved to Montana where she received her Bachelor’s degree in Forestry. This newfound knowledge prompted her to become a U.S. Peace Corps volunteer in the Philippines, which in turn showed her the power of education. Upon returning to the United States, Ms. Worssam became a professional educator and earned her Master’s Degree in Bilingual/Multicultural Education. Ms. Worssam has now taught in Arizona and internationally for over 14 years, and today teaches all curricular subjects to at-risk middle school students for the Flagstaff Unified School District. Thanks to support from NOAA, Ms. Worssam is participating both as a PolarTREC teacher and as a NOAA Teacher at Sea in this expedition.
Raymond Sambrotto is the chief scientist on the Bering Ecosystem Study (BEST) cruise and studies marine plankton ecology and global nutrient cycles. Dr. Sambrotto has worked from small boats in the Caribbean to major oceanographic programs in the Arabian Sea. He has worked extensively in high latitude regions at both poles using icebreakers and submarines to traverse these difficult environments. An important part of Dr. Sambrotto’s research is determining how marine populations will fare under changed climate conditions, and how these changes will affect the larger global environment.


A diverse research team aboard the U.S. Coast Guard Cutter (USCGS) Healy will conduct sampling along a series of transects over the eastern Bering Sea. Research on the ship is multidisciplinary, with scientists using a variety of techniques to document ocean conditions and the productivity of the Bering Sea ecosystem. Research teams will measure the temperature, salinity, and nutrient content of the sea water, changes in sea ice cover, and the concentration of nutrients used and released by phytoplankton. They will also conduct surveys of zooplankton, fish, seabirds, and marine mammals such as walrus and seal, to assess the health of these populations. These measurements will give scientists an indication of the current status of the Bering Sea ecosystem and any changes that might affect the use of its resources, and the economic, social and cultural sustainability of the people who depend on it. This is the third cruise in 2008 supported by the National Science Foundation’s Bering Ecosystem Study (BEST), which is part of a scientific effort to understand the Bering Sea. PolarTREC teacher, Jillian Worssam, is also being supported by the NOAA Teachers at Sea program to participate in this expedition. Click here to learn more about NOAA their education programs.


The team will be traveling on the USCGC Healy in the Bering Sea. The Bering Sea lies to the west of Alaska and to the east of Russia. The team will depart from and return to the port of Dutch Harbor, Alaska, the most productive fishing port in the United States.
