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
Podcast of the live TV interview with QATV journalist Joe Catalano. This interview is a follow-up to a previous discussion about the PolarTREC expedition.
Quincy Access Television interview to preview an upcoming talk at the Thomas Crane Library in Quincy, MA. The presentation is part of the series called At Your Library: Going Places
AM Quincy television interview with Quincy Access Television broadcast anchor Joe Catalano. This interview is a follow-up to the August 8th interview on the Currently in Quincy program. PolarTREC teacher Cara Pekarcik discusses her upcoming expedition and plans for community outreach.
Analogs are used in science investigations to better understand systems we can’t access ourselves. In this lesson, students explore the Dry Valleys of Antarctica to better understand microbial communities on early Earth and what might have been possible on ancient Mars. Students will examine photographs, written descriptions, and artistic renderings of early Earth, the Dry Valley lakes, and
This article summarizes the research of cyanobacterial mats in Lake Joyce during the 2014 field season. It describes the importance of the mats to better understand Earth history and understanding of other planetary systems. Additionally, it describes the sediment trap experiement that will conclude in the next field season.
On 6 October 2014, Capital Public Radio in Sacramento, CA interviewed Dawn Sumner, Tyler Mackey and Lucy Coleman on connections between the research in Lake Joyce, Antarctica, and work by the Mars Curiosity rover. To listen to the interview, click here.
Students will use the TAMMNET project and accompanying PolarTREC resources to learn about seismology in the Antarctic, culminating in the creation of an annotated map using google maps.
Objective:
Students will understand the different ways mountain ranges are formed, and appreciate the questions unanswered about the Transantarctic Mountains. Students will also appreciate the ingenuity required for doing research in
