Climate, behavior, ecology, and oceanography shape patterns of biodiversity in marine faunas in the absence of obvious geographic barriers. Marine turtles are an example of highly migratory creatures with deep evolutionary lineages and complex life histories that span both terrestrial and marine environments. Previous studies have focused on the deep(More)
We develop a non-parametric method to monitor several process variables simultaneously. This method is based on the concept of data depth, which indicates the position of an observation with respect to the data cloud. Principal components are used to reduce the dimensionality of the process, and a non-parametric chart is used to monitor some of the(More)
