Table 6. Kruskal-Wallis test results comparing length, mass and thickness at the depths 15m, 50m, and 100m at the open ocean station LP in January.

Measurements for all parameters were obtained from the light microscope images. df = degrees of freedom.

Mass	250	61	61	8.645	2	0.01
Mean thickness	250	61	61	27.120	2	<0.01
