Some of the most fundamental termi- nology used in the field of ocean acidification can be confusing and lead to improper conclusions. Of particular importance are the terms used to discuss fundamental acid-base relationships. For example, great care is needed to employ acid-base terminology appropriately and, as discussed in Theme 6; an effort should be made to explain this terminology to non- scientists in a way that provides an accurate image of the processes and mechanisms of ocean acidification. The terms “acid” and “acidic” have specific chemical meaning. A reduction in pH does not necessarily mean that the solution in question, e.g., seawater, has in fact become acidic (i.e.,

These terms may best be reserved for those exceptional conditions where seawater can actually become acidic (at CO2 vents or in manipulation experiments). Similarly, the term ‘alkalinity’ is best replaced with ‘total alkalinity’ and explained for nonscientific audiences. Another term that is often used ambiguously due to its different meanings in different disciplines is adap- tation. Whenever this term is used, it is essential to be explicit whether adaptation refers to biological adaptation or to human efforts to adapt to ocean acidification (e.g., through infrastructure or policy changes). In addition, ‘mitigation’ in the context of climate change refers to limiting carbon dioxide emissions. Thus, the Strategic Plan could be improved by using the term ‘mitigation’ or ‘to mitigate’ only in the context of lower- ing carbon dioxide emissions and not in the context of decreasing the impacts of ocean acidification. In that context, ‘adaptation’ is the more appropriate term as it refers to human interventions through changes in infrastructure or management of the marine resources. In Theme 2 terms such as ‘keystone species,’ ‘bellwether species,’ ‘indicator species’ are used seemingly interchangeable, despite the fact that ‘keystone species’ and ‘indicator species’ do not refer to the same concept. The inconsistent use of these terms needs to be reviewed in Theme 2 and confusion can be minimized by using terms more consistently with their original defini- tions. Given these issues, the committee offers the following definitions for the purpose of this report and suggest versions of these definitions be provided in the Strategic Plan: A  daptation: “Adjustment in natural or human systems to a new or changing environment that exploits beneficial opportunities or moder- ates negative effects” (NRC, 2010). H  ydrogen Ion Concentration: “The hydrogen ion concentration in sea- water is reported as pH=-lg[H+]” (Riebesell et al., 2010). I  ndicator Species: “A species whose presence, absence, or relative well- being in a given environment is a sign of the overall health of its ecosystem. By monitoring the condition and behavior of an indicator species, scientists can determine how changes in the environment are likely to affect other species that are more difficult to study.”1 1  Indicator species.

76 APPENDIX C T  otal Alkalinity: “The total alkalinity of a sea water sample is defined as the number of moles of hydrogen ion equivalent to the excess of proton acceptors (bases formed from weak acids with a dissociation constant K ≤ 10–4.5 at 25°C and zero ionic strength) over proton donors (acids with K > 10–4.5) in 1 kilogram of sample” (Dickson, 1981).
