My experience at McMurdo Station involved the study of neutrons caused by cosmic radiation from the sun. The sun can be very active. Changes in the sun's active surface can result in the ejection of high energy particles (from solar flares, coronal mass ejections, or related phenomena). Some of these particles can get sent toward the earth
The Importance of Teacher/Researcher Collaboration
It can be a humbling experience to admit that something isn’t easy, or that you don’t understand a topic or concept. It is harder still when you are surrounded by knowledgeable individuals and expected to explain their research in an accurate manner. While humbling, it is educational. Through learning about concepts such as trace metal
This lesson incorporates techniques and experimental designs used by researchers during the Southern Ocean Diatoms PolarTREC expedition and during post-expedition laboratory analysis. This guided inquiry lesson provides students the opportunity to explore photosynthesis and primary productivity using techniques to measure chlorophyll levels.
1. Use models to predict chlorophyll levels in the global oceans
When radioactive elements decay they emit high-speed particles. These can be detected by use of a cloud chamber. The cloud chamber was invented by Charles Thomson Rees Wilson in 1911. The chamber works by saturating the air inside with alcohol vapor. Cooling the chamber with dry ice supersaturates the air. The energetic particles produced by the radioactive decay ionize
This is a suite of labs created by Michigan State University and the Joint Institute for Nuclear Astrophysics (JINA). It provides a number of lessons and activities in nuclear physics. It can be used to demonstrate the types of reactions typical in cosmic ray interactions and the interactions that the CosRay neutron monitors depend on.
Understanding Physical and Chemical Parameters of Ocean Water Using CTD Profiles
A focus of the PolarTREC Southern Ocean Diatoms expedition was to collect water samples and physical profile data using oceanographic technology. Oceanographers rely on the real-time data transferred from the water column to the ship-based computers using a CTD sensor. The CTD measures conductivity (salinity), temperature and depth
