Building on a solid base of data regarding eggshell thickness

The 2010 and 2011 research teams have both built a solid base of data for eggshell thickness throughout the egg. Our project aim is to build a framework for analyzing this data and organizing it in a way to compare various regions of the egg. Our first step is to organize the actual data left from past research teams and become familiar with how and where the measurements were made. Upon organizing the data, we will construct a method for dividing the egg into sectors in order to compare the eggshell thickness of these sectors. There are various difficulties to this project, mostly from interpreting past research. The other obstacle comes from the sectors of the egg. We obviously can’t draw on the egg, so we are attempting to use a computer program to apply a grid to a photo of the egg. Using the grid/photo and past data we can assess how eggshell thickness changes. Of course, we are basing our radial sectors around the compression ridge (when present) so our data could be misinterpreted. We are currently working on a solution to this obstacle, and a way to correlate measurements across the specimens that aren’t crushed.
