NASA | The Hunt for P.I.G. in October
NASA's Operation IceBridge has launched its Antarctic 2012 campaign, flying high-priority missions measuring polar ice from a base of operations at the tip of Patagonia on the Strait of Magellan. They have even made a return visit to the...

OIB: McMurdo Accomplished, West Antarctica Calling
Last year Operation IceBridge flew for the first time out of McMurdo Station in Antarctica, reaching a new slate of exciting science targets. But that means it's now been two years since the mission has flown over critical areas in West...

NASA | Rendezvous with an Ice-Bound Vessel
Having just arrived in Greenland, the first challenge for the Operation IceBridge Arctic 2015 campaign was to survey a broad swath of Arctic sea ice … and along the way, locate and precisely overfly a Norwegian research vessel frozen in...

NASA | Daily Arctic Sea Ice 2005-2006
This animation shows the seasonal advance and retreat of sea ice over the Arctic from 2005-2006. The false color of the sea ice, derived from the AMSR-E instrument on NASA's Aqua satellite, highlights the fissures in the sea ice by...

NASA Measuring Sea Ice at the Peak of Melt
The Arctic sea ice pack is nearing its annual minimum extent, which is projected to be one of the lowest since satellite observations began. Using satellite data and airborne observations, NASA researchers are monitoring the...

NASA | OIB Flights South 2014: Mission Overview
Consistency counts when collecting scientific data. With global ice inventories in a profound state of change, it’s essential to maintain regular measurements of ice at the poles. NASA’s ICESat satellite amassed a substantial body of...

NASA | Arctic Cyclone Breaks Up Sea Ice
Watch how the winds of a large Arctic cyclone broke up the thinning sea ice cover of the Arctic Ocean in early August 2012. The storm likely contributed to the ice cap's shrinking to the smallest recorded extent in the past three...

NASA | Jakobshavn Glacier Retreat
Since measurements of Jakobshavn Isbrae were first taken in 1850, the glacier has gradually receded, finally coming to rest at a certain point for the past 5 decades. However, from 1997 to 2006, the glacier has begun to recede again,...

Big Year for NASA’s IceBridge in 2017
From the South Pole to Greenland, from Alaska’s glaciers to Svalbard, NASA’s Operation IceBridge covered the icy regions of our planet in 2017 with a record seven separate field campaigns. The mission of IceBridge, NASA’s longest-running...

Performing Thin Layer Chromatography (TLC)
We've learned a few separation techniques, so how about one more? Chromatography separates components of a mixture by virtue of their differing polarities, and thin layer chromatography, or TLC, is an invaluable technique that is used...

Water and Diffusion - The Chemistry of Life
In this section, I talk about the properties of water, and what makes it unique. I talk about hydrogen bonds that result from the polar nature of water and why ice floats.
I also deal with diffusion and go into the 3 factors that affect...

The Plasma Membrane - A view of the cell
The plasma membrane is responsible for maintaining a balance. In this section, I talk about both the structure and the function of the plasma membrane. I deal with the components of the plasma membrane and their functions.

Non-Ideal Gases and the Van der Waals Equation
We learned about ideal gases, as well as kinetic molecular theory, which explains the laws that govern ideal gases. But some of the postulates of this theory won't always hold true. When a gas is highly pressurized and/or very cold, it...

Introduction to Circular Motion and Arc Length
Cartesian and polar coordinates are introduced and how to switch from one to the other is derived. The concept of angular displacement and arc length are demonstrated. Circumference is shown to be an arc length.
