Table 1. — Statistics summarizing the results of the clustering algorithm showing the 

 sensitivity to a range of values for the clustering parameter. Standard deviations are 

 given as opposed to standard errors to provide an indication of the variation between 

 cruises. All means are the simple average for 35 cruises.
