TEK TALKS is a series of webinars that was developed to foster understanding among scientists in regard to working with Indigenous People. View archived lectures and/or sign up for future lectures through the website.
A working group was convened in late May, 2019, for the purpose of developing guidance to North Pacific Research Board (NPRB) and Alaska Sea Grant (ASG) to encourage and support outreach by researchers to Alaska’s K-12 Indigenous students in culturally responsive ways. The impetus for the working group was a disconnect we perceived between an increasing emphasis on inclusion of
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
