After conducting a shore keepers survey, the four data sets are digitized and geographically referenced in Ozi Explorer. These geo-ref images are then placed in the Google earth landscape referencing visual markers with the image and laying the image over the topographic images in Google Earth.
ES students collect and map on a grid information 20 m above high tide lines, identifying all significant features. Another group map the drift wood along the high tide line, a third group lay out a grid of 100 m lines to create a number of 20 m squares. These squares serve as reference points for plotting the ecozones within the study area. The fourth group of students set out 50 cm square quadrat plots at .5 meter intervals above zero tide. The count and record surface animals and algae, then repeat the process between 0 and 10 cm depth in movable substrates. They then go to 30 cm depth. At each phase, they sieve, wash, identify, count and record all animals and algae.
Following data collection and mapping phase, students digitize each polygon in Corel Draw. The drawing corresponds to the maked baseline used in the Shore Keepers procedure. This image is fused and is then imported into Ozi Explored where it is geo-referenced using the program and the known locations on the map image.
Successive years of images may be viewed by altering the opacity of other images at the same location. This process gives a visual illustration of changes that occur within the intertidal study areas.
