TOMS Ozone at the South Pole: October Averages from 1979 through 2000
The year 2000s Antarctic ozone hole is the largest ever observed. Scientists continue to investigate the phenomenon, and are somewhat surprised by its scale. Using data from NASAs Total Ozone Mapping Spectrometer (TOMS) instrument onboard the Earth Probe satellite, researchers can evaluate and compare current conditions over the south pole to readings taken by other instruments in years past. Continued monitoring of polar ozone levels helps researchers gain a better understanding of how the plan
Minimum Measured Ozone Level in 1998
Stratospheric Ozone level for September 30, 1998.
Temperature of the Gulf Stream
This site Presents a MODIS (Moderate-resolution Imaging Spectroradiometer) image of the Gulf Stream. The image is color-coded to show the variation in temperature of the ocean water. A brief description of the Gulf Stream, its direction and speed, and a link to other related imagery are included.

Social Factors in Health and Disease Fall 2007
Social Factors in Health and Disease (Guest: L. Syme). From Public Health 250A: Epidemiologic Methods I - Fall 2007. Principles and methods of epidemiology: study design, selection, and definition of cases and controls; sampling, data collection, analysis, and inference. Discussion session provides an opportunity to apply methods to problem sets and to discuss issues presented in lectures.
Progression of Hurricane Charley, 2004 (WMS)
Hurricane Charley was the first of four hurricanes to hit the United States in 2004.
El Nino Sea Surface Temperature, Height, and Wind Anomaly Onionskin: January 1997 through December 1
El Nino sea surface temperature, height, and wind anomalies in the Pacific for January 1997 through December 1997. The data sets are added one layer at a time, followed by a zoom into the eastern Pacific. (Wind anomalies stop at October 1997)
Christie Clark gets serenaded for Earth Day
Students from University Highlands elementary school performed an Earth Day song for B.C. premier Christy Clark in the Djavad Mowafaghian Courtyard at Blusson Hall. BC premier Christy Clark was at SFU Burnaby to announce funding for a new neighbourhood energy utility on Burnaby Mountain. This district energy system will provide heat for the whole campus plus future homes in the UniverCity sustainable community. It will also replace SFU's aging boilers and help reduce 80 per cent of the school's

Finding The Right Institutional Fit For You: How To (Safely) Find Out About The Culture Of The Depar
Presentation in the 2008 Rice University NSF Advance Conference entitled “Negotiating the Ideal Faculty Position”. This presentation was designed to assist and educate the interviewee regarding campus culture and atmosphere, and was authored by Laura Malisheski (Harvard), Margaret Beier (Psychology), Vicki Colvin (Chemistry), and Jim Pomerantz (Psychology).
Fluorescence Microscopy as an Introduction to Cell Biology
In this exercise, students use fluorescence microscopy to look at organelles (mitochondria, Golgi apparatus, endoplasmic reticulum) and the cytoskeleton in PtK2 cells. In both cases, DNA stains allow students to observe changes in organelle and cytoskeleton morphology as the cell undergoes mitosis. In addition to revealing the cellular structures in a dramatic fashion, the exercise shows students that the distributions, sizes, and shapes of the structures are not always as they imagine them. Fin
Exploring Important Biological Concepts Using Biology Workbench
This set of three activities uses Biology Workbench, a website that brings together sequence databases and online software for searching databases, aligning sequences, and creating inferred phylogenetic trees. The first two activities explore the diversity of preproinsulin sequences across species. Students use the Student Version of Biology Workbench and search databases by keyword in the first activity, while, in the second, students use the actual Biology Workbench and search the databases us
Exercise Physiology: The Response of Metabolic Rate to Physical Activity
In this lab, students measure their heart rate, oxygen consumption, and carbon dioxide production in various physical activities on a treadmill or cycle ergometer. After learning the techniques in the first lab period, each group of 3-4 students designs an independent investigation that is performed during the second lab period. To measure metabolic rate, students collect expired air in a Douglas bag, then measure the volume, the temperature, and the concentration of oxygen and carbon dioxide. W
Eutrophication: A Project Lab for Multi-section Lab Courses
This lab is designed to simulate the process of eutrophication over an eight to ten week period. Students use a water-soluble fertilizer (similar to Miracle Grow) to determine the effects of nutrient loads on both terrestrial and aquatic environments. By using three aquariums, Elodea, and radish plants, students can examine the ongoing process of eutrophication by taking weekly measurements of water quality and looking at plant growth. Students become "experts" on such equipment as dissolved oxy
Effective Methods of Training Biology Laboratory Teaching Assistants IV: The Use of Skits, A Teachin
Each year since 1999 ABLE has provided a forum for presentation, discussion, and sharing of ideas concerning the use of undergraduates and graduate students to run labs and teach in the Departments of Biological Science. There have been lively films, games, examples, and discussions of the many university training sessions and/or workshops to Train Graduate Teaching Assistants to handle students, labs, and even teaching assignments. This year we will offer four other areas of discussion for you.
