Abiotic characteristics of bottom water associated with all stations sampled and stations where squatinid sharks were 
captured in waters along the East Coast (EC) of the United States and throughout the northern Gulf of Mexico (GOM) 
over varied time series during 1950-2016. All P-values for the Mann-Whitney-Wilcoxon (W) and Kolmogorov-Smirnov 
(K-S) tests were less than 0.01. Mean values are given with standard errors (SEs).
