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
This scientific article, focuses on one of the largest pools of global carbon that is, the organic C stored in permafrost (perennially frozen) ground, and on the vulnerability to change under an increasingly warmer climate.
Have you ever wondered how polar scientists do it? How do they really know if the planet is losing vast quantities of ice anyway? You can use pictures from satellites to monitor the surface from year to year, but the vast majority of ice is hidden from view, buried beneath the surface in some of the most inhospitable and
A scientific report describing the results of the CiPEHR Experiment as of 2011. This report attempts to answer these questions:
(1) Does ecosystem warming cause a net release of C from the ecosystem to the atmosphere?,
(2) Does the decomposition of old C that comprises the bulk of the soil C pool influence ecosystem C loss?, and
(3) How do
The Geophysical Institute Permafrost Laboratory (GIPL)
The Permafrost Laboratory deals with scientific questions related to the circumpolar permafrost dynamics and feedbacks between permafrost and global change. At the Permafrost Laboratory, data related to the thermal and structural state of circumpolar permafrost is collected and analyzed. The focus of our research is the development of methods to physically and mathematically model
In mid-April 2012, five teachers from Denmark, Greenland, and the United States, were given the experience of a lifetime. The teachers lived, worked, and flew alongside airborne polar scientists in Greenland, and saw firsthand how remote data are collected on NASA’s Operation IceBridge. In the process, the experience provided the educators with better tools to teach students about science. Read
