Dataset: Lab study on the effect of temperature and pCO2 on mussel byssal attachment (thread number) with mussels collected in May 2012 from Argyle Creek, San Juan Island, WA (48.52˚ N, 123.01˚ W)

These data were used in a structural analysis study to evaluate how pCO2 and an additional stressor, elevated temperature, influences byssal thread quality and production. Mussels (M. trossulus) were collected in May 2012 from Argyle Creek, San Juan Island, WA (48.52˚ N, 123.01˚ W) and held in a mesh box submerged under the dock at Friday Harbor Laboratories (FHL), San Juan Island, WA for up to 14 d. Mussels were placed in controlled temperature and pCO2 treatments in the Ocean Acidification Experimental Laboratory (OAEL), then newly produced threads were counted and pulled to failure to determine byssus strength.
