Cruise Report for the R/V Sikuliaq August 25-September 18, 2017, prepared by Dr. Carin Ashjian, Chief Scientist, and the SKQ201713S Science Team for the time PolarTREC teacher Lisa Seff was aboard and working on Upwelling and Ecology in the Beaufort Sea.
Article written for the East Hampton Star Newspaper on September 7, 2017, featuring teacher Lisa Seff aboard the R/V Sikuliaq in the Beaufort Sea studying Upwelling and Ecology in the Bering Sea.
Article run in the East Hampton Star Newspaper on February 16, 2017, about teacher Lisa Seff's participation in the expedition "Upwelling and Ecology in the Bering Sea" aboard the R/V Sikuliaq in the Beaufort Sea.
PolarTREC teacher Lisa Seff and the "Upwelling and Ecology in the Beaufort Sea Research Team" discuss the many research projects being carried out aboard the R/V Sikuliaq. This event was broadcast live on 14 September 2017 from the research vessel located in the Beaufort Sea.
Researcher Elizabeth Webb discusses her experiences working in the field with a PolarTREC teacher. She worked with John Wood in 2011 and 2012, and Tom Lane in 2013, on the Carbon Balance in Warming and Drying Tundra expedition near Healy, Alaska. (She primarily discusses her time with John Wood since this interview was taken in 2013, before Tom Lane's expedition.)
Soil decomposers, such as some bacteria and fungi, obtain energy needed for life from dead and decomposing plant and animal remains, known as soil organic matter. Soil organic matter is important to local ecosystems because it affects soil structure, regulates soil moisture and temperature, and provides energy and nutrients to soil organisms. It is also important globally, because
Models are great to use to make a concept easier to understand, to visualize a process or outcome, and also to allow a scientist to test selected variables. IMOLD is a great model of leaf decomposition, because it allows the students to interact with two variables affecting decomposition rates, and test those variables in many more ways than they could
This lesson describes how decomposition happens, and the role of microorganisms in this process. The animation, which runs for 3:23 minutes total time, covers information that students may or may not be familiar with. Here is one suggestion for working your students through the animation. By actively taking notes during the animations, students can engage in a dialogue with the
The purpose of this lesson is to highlight the importance of the structure of a leaf at its implications for how it decomposes. The animation, which runs for 2:03 minutes total time, covers information that students may or may not be familiar with. Here is one suggestion for working your students through the animation. By actively taking notes during the
The purpose of this lesson is to highlight the importance of the Carbon Cycle in the natural cycles of photosynthesis and respiration. It also models how human activity can alter the carbon cycle. The animation, which runs for 2:56 minutes total time, covers a large amount of information that students may or may not be familiar with. Here is one
