        abstract:  This is data from a laboratory experiment in which mature female Tanner crabs were held at three different pHs (ambient, pH 7.8, and pH 7.5) for approximately two years. The laboratory exposure started on 2011-06-21 and ended on 2013-07-14. At the end of the exposure period samples of both the exoskeleton and claw were taken. Exoskeleton mechanical and elemental properties were analyzed in both the carapace and the claw. This dataset includes only the data from the cuticle analysis. The results of this work are published as: Dickenson, G.H., Bejerano, S., Salvador, T., Makdisi, C., Patel, S., Long, W.C., Swiney, K.M., Foy, R.J., Steffel, B.V., Smith, K.E., and Aaronson, R.B. 2021. Ocean acidification alters exoskeleton properties in adult Tanner crabs, Chionoecetes baridi. J. Exp. Biol. 224: jeb232819. https://doi.org/10.1242/jeb.232819.
        purpose:  This dataset is available to the public for a wide variety of uses including scientific research and analysis.
