Mussels were collected from Penn Cove Shellfish Farm in Penn Cove, WA, a coastal environment influenced by freshwater input. The experiment used multiple treatment types designed to decouple carbonate system parameters commonly altered by freshwater runoff, which influences seawater carbonate chemistry through changes in total alkalinity (TA) and dissolved inorganic carbon (DIC), with subsequent shifts in pH, [HCO3−], [CO3²−], and saturation state (Ω). \n\n\n\nThe dataset includes seawater carbonate chemistry conditions (e.g., pH, total alkalinity (TA), DIC, [HCO3−], pCO2, Ω, and [Ca2+]) and biological response measurements of calcification and dissolution rates. Experimental treatments included: (1) multiple treatments spanning low-to-high pH and [HCO3−]; (2) a range of saturation states under high and low [HCO3−] conditions using both live mussels and de-fleshed mussel shells; and (3) calcium manipulations to distinguish the relative influence of pH versus Ω on calcification by altering [Ca2+] independently of pH.\n\n\n\nThis dataset describes treatment conditions, shell and tissue mass, carbonate system calculations, and calcification and dissolution rates calculated using the ammonia-corrected alkalinity anomaly technique (Gazeau et al. 2013). Future researchers can use this data to examine the effect of freshwater-influenced seawater conditions on calcification responses in coastal calcifying organisms. Datasets are provided in .csv format for maximum accessibility and interoperability.\n\ncdm_data_type = Other\nVARIABLES:\nmussel_number (unitless)\nspecies (unitless)\nscientific_name (unitless)\naphia_id (unitless)\n...

However, how calcification is impacted by ongoing environmental changes, including ocean acidification, remains incompletely understood due to complex relationships among the carbonate system variables hypothesized to drive calcification. \n\nHere, we experimentally decouple these drivers in an exploration of shell formation in adult marine mussels, Mytilus californianus. In contrast to models that focus on single parameters like calcium carbonate saturation state, our results implicate two independent factors, bicarbonate concentration and seawater pH, in governing calcification. While qualitatively similar to ideas embodied in the related substrate-inhibitor ratio (bicarbonate divided by hydrogen ion concentration), our data highlight that merging bicarbonate ion and hydrogen ion concentrations into a simple quotient obscures important features of calcification. Considering a dual-parameter framework improves mechanistic understanding of how calcifiers interact with complex and changing chemical conditions.\n\ncdm_data_type = Other\nVARIABLES:\nspecies (unitless)\nAphiaID (unitless)\nLSID (unitless)\nmodule (unitless)\ndate_local (unitless)\nstart_datetime_local (unitless)\nISO_Start_DateTime_UTC (unitless)\nduration (hours)\nsalinity (PSU)\ntemperature (degrees Celcius (c))\ncalcification (umol hr^-1 g^-0.71592)\ntissue_mass (grams (g))\nshell_mass (grams (g))\nwet_mass (grams (g))\n...
