How do we know what kind of phytoplankton are in the water? The Imaging FlowCytobot (IFCB) is a robot that scientists use to image phytoplankton in the water. One IFCB can take up to 30,000 pictures per hour! The IFCB can be used in the field to detect plankton blooms in real time. In this activity, students will practice
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
One of the most important indicators of our warming climate is the extent and thickness of polar sea ice. Currently satellites measure the extent of polar sea ice but it takes more sophisticated equipment aboard a low-flying plane to actually measure the thickness of sea ice. This lesson will show students how this is done.
