Oftentimes called “ghost particles,” neutrinos can travel through nearly everything (the sun, the earth, you!) undetected. Because they are nearly massless, gravitational fields do not affect neutrinos; Similarly, because they are chargeless, electric and magnetic fields do not con affect neutrinos. This lack of interaction is advantageous for IceCube researchers – when they detect a neutrino, it is a
In this lesson, students will be introduced to the Standard Model, learning key vocabulary such as Fermions, Hadrons, Mesons, Baryons, Quarks, Leptons, particles, and anti-particles. In particular, students will come to understand what a neutrino is and why it is such a unique particle. This understanding connects to the IceCube Neutrino Observatory’s search for neutrinos in an effort to
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.
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
Nature creates its own density column in marine systems, which is extremely important for the triggering of the spring bloom of phytoplankton. Phytoplankton are an important food source for all organisms- from microscopic zooplankton to large marine mammals such as walrus and whales. The different salinities (and therefore, different densities) of water help to stabilize the water column (by limiting
