This lesson was created by Rebecca Harris after being a part of the Arctic Glacial Lakes PolarTREC Expedition. She was inspired by how important suspended sediment, something so often overlooked by non scientists, was for developing paleoclimate models as well as ecosystems. Students will observe a watershed or a model of a watershed to make predictions about what might
This lesson plan was created by after being a part of the Arctic Glacial Lakes PolarTREC Expedition. I was inspired by the massive amount of data collected over the course of the research project and the complexity of hydrology in glaciated and non-glaciated basins in the Brooks Range of Alaska. Students will work together to make hypotheses about patterns
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
Through this demonstration and review of the attached research documents and the expedition PolarConnect event archive you will better be able to visualize how warming deep ocean currents undermine the ice sheets of Antarctica.
Objectives
To determine, through a demonstration and review of a scientific abstract, how warm water currents speed up ice sheet loss and sub-ice
As a teacher on the NB Palmer Totten Cruise in the winter of 2014, I successfully traversed the Magnetic South Pole. This is a wandering point on the Earth’s surface where geomagnetic field lines are directed vertically upwards. As an Outdoor Educator I utilize compasses regularly to navigate. The traverse of the Magnetic South Pole inspired this lesson
Even in Antarctica ice will melt. As the sun stays higher and higher in the sky as summer progresses, the warm sun causes the ice to melt. The questions that we are going to ask are: 1) Does clean ice (no sediment) or dirty ice (has sediment mixed in it) melt faster? and 2) Would the ice melt if
For this experiment, we are going to melt dirty ice (ice with lots of sediment/dirt in it) and clean ice (ice without sediment) from the Taylor Glacier. After we melt the ice, we are going to test the melt water for pH and conductivity, and then determine how much salt is actually in our ice samples. There are
Case studies provide a brief overview or examination of events that impact or alter the way people function and live day to day within the human and physical environment. They help by providing students with “real world” examples that relate to the theoretical content they are studying.
Objective
Students will prepare a case study illustrating the impact
