La educadora informal de PolarTREC, Jocelyn Argueta, viajó al Polo Sur en 2019 con el Observatorio IceCube Neutrino y la Expedición Askaryan Radio Array. Creó una serie de YouTube Hielo Pequeño: Pedazos de la Antártida para explicar el viaje, la ciencia y la vida en el Polo Sur, tanto en inglés como en español. En esta serie
The PolarTREC Field Experience is amazing! PolarTREC (Polar Teachers Researchers and Educators Exploring and Collaborating) matches polar researchers with educators to highlight, and increase accessibility to, the science happening in some of the most fascinating places on our planet—the Arctic and Antarctic regions. It is an opportunity for educators to be completely immersed in the culture
This article and associated video describe the findings of researchers who undertook core drilling at Lake El’gygytgyn, a lake that sits today inside a basin formed by a meteorite that struck the earth 3.6 million years ago. An associated video allows us to hear the enthusiasm and details as researcher Julie Brigham-Grette describes the findings of this remarkable discovery.
This geologic time calculator allows the user to manipulate the relativism of time to other markers. It builds from the classic analogy for illustrating the relative durations of parts of the geologic time scale is the yardstick.
Humans are creative. They try to solve problems in original ways. For example, some scientists are thinking of ways to decrease the amount of greenhouse gases in the air. Other scientists are thinking of ways to limit the amount of sun that reaches Earth so that the Earth won’t get so warm. Like most ideas, there are pros (good
Textbooks say that carbon dioxide is a greenhouse gas and can make earth's climate hotter. Try this lab to see if carbon dioxide gas can really act like a greenhouse.
Objectives
Students should be able to make a hypothesis, perform an experiment, analyze data and write a conclusion based on the evidence from their experiment.
Lake El'gygytgyn (67.5º N, 172º E) is one of the best preserved large asteroid impact craters on earth. In the winter of 2009, I joined an international science team and traveled to the frozen arctic lake to drill and extract lake sediments to study climate change as well as sample the rocks that were changed when the crater
The sediment in Lake El'gygytgyn, (pronounced EL-ge-GIT-gin) located in NE Siberia, holds one of the longest records of climate change anywhere in the continental Arctic. How does sediment (clay and mud) tell us something about past climate? Proxy data! By studying the microfossils of diatoms and pollen in the sediment, we can re-construct the lake environment millions of
