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
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.
Objectives
SWBAT:
1. Use models to predict chlorophyll levels in the global oceans
2. Identify
Understanding Physical and Chemical Parameters of Ocean Water Using CTD Profiles
Overview
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
Students will observe how soils and rocks of different densities behave in wind and in water. They will make predictions and careful observations as they learn about sediment transport and sediment rates in streams and rivers.
