Detecting El Niño in Sea Surface Temperature Data
SST anomalies for December 1997 displayed in My World GIS. Red indicates above average temperatures compared to average SST temperatures for December data averaged over the years 1982-1998. This chapter introduces you to normal seasonal sea surface temperature (SST) variation as well as extreme variation, as in the case of El Niño and La Niña events, in the equatorial Pacific Ocean. You will learn how to download seasonal SST data from the Pacific Marine Environmental Laboratory (PMEL), via a THREDDS server, for the years 1982 to 1998. With My World GIS, you will visualize and analyze that data, looking for the tell-tale SST signature of El Niño and La Niña events that occurred during that time period. At the conclusion of the chapter, you will be given the opportunity to analyze a season of your own choosing to determine if an El Niño and La Niña SST pattern emerged in that year's data.
NOAA Interactive GIS Climate Maps
This website contains an interactive GIS map with global temperatures, precipitation, ecosystems, population and other layers. The tool can zoom in and out, provide limited geographic information, and display a variety of climatic information.
GIS Imagery for Haiti Earthquake
A collection of GIS map data compiled by Google Crisis Response, containing downloadable high-resolution images from several sources.
Globe Watersheds Module 1: Water Availability
The GLOBE Watershed Dynamics Module 1 GIS tool is a freely available web-based GIS. This tool allows users to analyze precipitation, evaporation, and surface runoff data across the US. Curriculum is available for this project upon request at this time (March, 2010), but will be available through Northwestern University Office of STEM Education Partnerships and through the GLOBE Program Office in the future. Contact Colleen Buzby for more information. c-buzby AT northwestern.edu
SERTIT satellite maps of Haiti
This page from SERTIT Rapid Mapping includes a collection of annotated satellite maps (some in French) showing damage distribution, gathering areas, water sources, and other information.
ERDAS Haiti Response Map
This interactive map from the ERDAS APOLLO Client includes layers that can be toggled on and off. Layers include damaged buildings, IDP sites, and impassable roads.
My World GIS
My World is a Geographic Information System (GIS) designed specifically for use in middle school through college classrooms. My World provides a carefully selected subset of the features of a professional GIS environment. These features include multiple geographic projections, table and map views of data, distance-measurement tools, buffering and query operations, and customizable map display. They have been selected to provide the greatest value to students without overwhelming them with complexity. The features are accessed through a supportive interface designed with the needs of students and teachers in mind. My World can import data from the industry-standard shapefile format, as well as from tab and comma-delimited text files. In the future, it will be able to communicate directly with GPS-enabled handheld devices. The web site features links to download My World GIS software along with sample data and documentation. This resource is part of the Using Global Data Sets collection. http://serc.carleton.edu/NAGTWorkshops/globaldata02/
