Depth and thickness of aragonite undersaturated water in the Canada Basin

Depth and thickness of aragonite undersaturated layer, estimated from CTD-S profiles. See the reference for the method. Top boundary is the bottom depth of the surface undersaturated layer. Mid and low boundaries are upper and lower boundaries of subsurface undersaturated layer, repectively.基于CTD-S剖面估算得到的文石不饱和层（aragonite undersaturated layer）深度与厚度，具体计算方法参见参考文献。该文石不饱和层的顶层边界为表层文石不饱和层的底部深度；其中层边界与底层边界分别对应次表层文石不饱和层的上边界与下边界。
