PolarTREC expeditions to the Arctic and Antarctica can be found here starting in 2007 to present. You can also access archived expeditions to the Arctic that took place through TREC in 2004-2006. Journals, photos, ask the team forums, and information about each expedition can be found by following the links to all the expeditions. Use the Expedition Search feature to narrow your choices or find a particular expedition or region. Use the Members feature to find teachers and researchers involved with PolarTREC expeditions.
Another interesting perspective for viewing expeditions are Projects. Projects are expeditions that had teachers for more than one year. You can learn more about the science and see all the teachers and researchers involved in the research project over two or more years. You can also access all the related project resources (presentations, lessons, PolarConnect events, etc.) related to the projects.
Thermal Sensitivity of Embryos and Larvae of Antarctic Marine Ectotherms 2021
Dates
15 October 2021 - 15 November 2021
Location
McMurdo Field Station, Antarctica
What Are They Doing?
Cold-blooded animals in the Antarctic ocean have survived in near-constant, extreme cold conditions for millions of years and are very sensitive to even small changes in water temperature. However, the consequences of this extreme thermal sensitivity for the energetics, development, and survival of developing embryos is not well understood.
This project will investigate the effect of temperature on the metabolism, growth rate, developmental rate, and developmental energetics of embryos and larvae of Antarctic marine ectotherms. The project will also measure annual variation in temperature and oxygen at different sites in McMurdo Sound, and compare embryonic and larval metabolism in winter and summer to determine the extent to which these life stages can acclimate to seasonal shifts. This research will provide insight into the ability of polar marine animals and ecosystems to withstand warming polar ocean conditions.
