Float Your Boat is an outreach project of the International Arctic Buoy Programme. It is a project for community members and students to learn about the Arctic Ocean – its' circulation, its' sea-ice cover, and how it’s changing. Participants learn about the Arctic Ocean and sea ice, decorate a small wooden boat, and then watch via an online map, their
KBRW Top of the World Radio host Bob Thomson interviews International Arctic Buoy Programme Director Ignatius Rigor and PolarTREC Educator Sarah R Johnson on Friday, April 1, 2022 in Utqiagvik, Alaska during the morning news hour.
On this episode of "Hey, You're Pretty Good at That" on KDNK Community Radio in Carbondale, Colorado Host Ape on the Dink chats with local environmental educator Sarah Johnson about polar adventures, environmental education, and her recent trip to Scotland.
This activity was prepared by David Walker (LASA High School) and Rose Cory (University of Michigan), based on work conducted at Toolik Field Station in Alaska. The purpose is to introduce students to Van Krevelen diagrams, which are used to interpret results of high resolution mass spectrometry and characterize the compound classes present in complex organic mixtures. Students will
The work of professor Bryon Crump, graduate student Natasha Christman, and PolarTREC teacher David Walker is highlighted in the weekly newsletter of the Oregon State University College of Earth, Ocean, and Atmospheric Sciences (On the Horizon).
KUT (Austin's NPR Station) news report (video, article, and radio) on PolarTREC teacher David Walker's Carbon in the Arctic expedition. The story aired on Morning Edition and Texas Standard in late-September, 2019.
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
