  1. USING AN INTERNET MAP SERVER AND COASTAL REMOTE SENSING FOR EDUCATION Peter A. Bower June 8th 2005

  2. Overview • Introduction/Justification • Methods • Data Gathering/Processing • IMS Building • Teacher workshops • Results • IMS Build • Lessons written • Feedback • Discussion • Future Work

  3. Introduction • Increasingly globalized society • Need for geographic literacy • More technology in daily lives • Keeping pace • Powerful Tools Available for geographic inquiry • Geographic Information Systems (GIS) • Remote Sensing (R/S) • Schools working to integrate technology • Science striving to engage public

  4. Previous Findings • Kerski 2001 extensive study in adoption of GIS in High Schools • 2% in US have adopted • Those who have GIS 20% use more than once • Kerski others found barriers to GIS • Computing hardware/facilities • Time, time, time (prep/software instruction to Teach/Stu) • Data processing • Instructor training (educator geared) • Perceived software difficulty

  5. Research Questions • Can an IMS site be used effectivelyto teach students at the high-school level about remote sensing, large-scale oceanography concepts, and biological interactions? • What are some of the impediments to successful implementation of an IMS and possible solutions?

  6. Project Goals • Design an IMS Web site, the Oregon Coastal Marine Viewer (OCMV) using ocean remote sensing, and oceanography data that are user-friendly to teachers and students • Develop educational modules to complement the web site for SMILE activities

  7. Project Goals • Introduce teachers to GIS, remote sensing, and oceanography and how to use the IMS site in a series of workshops: one in the summer to introduce ideas, and one in the winter to introduce the working OCMV site and specific IMS lessons, • Obtain feedback to improve the site and identify impediments to successful IMS integration.

  8. Collaborators • CIOSS - Cooperative Institute for Oceanographic Satellite Studies • SMILE - Science & Math Investigative Learning Experience • Focus on students (mostly rural) who are underrepresented/underserved in math and science • Science and math enrichment activities at weekly after school club meeting to foster students interest in college studies

  9. SMILE Schools in Oregon

  10. Data Used/Collection • Base Layer Data (State, Cities) • Sea Surface Temperature (SST) • Ocean Chlorophyll Concentration (Ocean Color) • Plankton Net Samples • Bird Observations • Mammal Observations

  11. US GLOBEC Study Area Ship Track R/V Roger Revelle (August )

  12. Advanced Very High Resolution Radiometer AVHRR Global Coverage of Sea Surface Temperature Images Raw data processed to an output grid values of 0-25.5o Cat 1.3 Km resolution obtained from US Globec NE Pacific Project Satellite Data Archive/ COAS

  13. Sea-viewing Wide Field Sensor (SeaWiFS) 8-Day Composite Images Courtesy of Dr. Andrew Thomas, University of Maine, Satellite Oceanography Data Laboratory Chlorophyll concentration values collected in milligrams chlorophyll per cubic meter with a resolution of 4km

  14. R/V New Horizon R/V New Horizon in Newport Oregon with plankton sampling net visible on stern waiting deployment

  15. Plankton Sampling Net System MOCCNESS Multiple Opening/Closing Net and Environmental Sampling System Diagram US GLOBEC

  16. Mammal and Bird Observation Data Collection R/V Roger Revelle, Scripps - UCSD 25 x 150 Binoculars 6 nautical mile range on clear days

  17. Data Processing • Converted Binary SST images to TIFFs andGeoreferenced in ArcMap • Georeferenced SeaWiFS 8-Day Composite Images • Text File to Shapefile for • Plankton Net Tows • Bird Observations • Mammal Observations

  18. Data Processing • Data Simplification • Large number of point data for two time periods early summer, later summer • Multiple data layers selected at the same time overwhelming to students teachers • Data subsets selected and new layers created • Data attribute tables large and confusing • Simplified Number of columns • Added common names for birds/mammals

  19. Data Simplification An example of simplified bird data

  20. IMS Basic Workflow • Client • Server • Web Server • Servlet engine • Spatial Server

  21. IMS Site Construction • ArcIMS Author and Designer used for creation of basic Layout and Map Service • Manual File Editing to customize • Grid Display • Layout of web site customized from default • Layers/Legend • Buttons • Links • Color/Appearance

  22. Oregon Coastal Marine Viewer

  23. OCMV SST Layers June 13, 2000 August 2, 2000

  24. SeaWiFS 8-Day CompositeJune 4-11, 2000

  25. SeaWiFS 8-Day CompositeJuly 28-August 24, 2000

  26. Lessons • Progressive lessons constructed and presented to teachers at two SMILE teacher workshops • Mapping school and resolution R/S (SUMMER) • Intro to GIS/IMS navigation using SST/Ocean Color (Winter) • Using R/S imagery and biological data (Winter)

  27. Feedback • Teachers difficult to get a hold of • Workshop positive/negative • Too much in 2 hours? (limited technology skills) • Though it was interesting • Problems with computer lab access • Map service down • School computer lab issue (Firewall?) • Lack of time with students

  28. Feedback • Limited time spent by teachers • Fairly easy to navigate • After workshop (2 hours) Limited prep-time • Central computer with projector • Students seemed to understand material (Depth?...)

  29. Feedback • Interested in using more lessons • Marine Science • Outdoor field course (mapping/resolution) • District technology integration • Marine Science and technology integration • A good activity for visual learners

  30. Discussion • Exposed 150+ students to GIS Remote Sensing and Oceanography • Time for teacher education very short • Permanent site set up with lessons written assuming no workshop • Although perhaps not all students were able to use IMS now have some exposure and if interested could use own time (home, library)

  31. Discussion • More data available for addition to IMS site • Other outreach activities more information on research cruises available for further study • Some barriers encountered similar to desktop GIS • Computer lab availability • Network/server issues • Teacher education time (much less required)

  32. Next Steps • Fix a few • Add Links page for electronic Lessons for download and Credits page • Link to US GLOBEC web Outreach Material • Recent server stability/image serving issues?

  33. Next Steps, Continued • Online link from the Oregon Coastal Atlas • Publish? The National Marine Science Educators publication, Currents: The Journal of Marine Education • Online publish? on the BRIDGE web page (maintained by NMSE) • Marine Advanced Technology Education (MATE) Center link

  34. SMILE Challenge Mock Oil Spill Response Group Project
