Unlike pelagic
ecosystems,
coastal ecosystems are often dominated by benthic
ecosystems,
including engineering species (e.g. corals, seagrass, macroalgae, salt marshes, mangroves, sponges, oyster reefs) with the capacity to modulate the chemical and physical conditions of their environment (Gutiérrez et al. 2011).
However, changes in pH in
coastal ecosystems result from a multitude of drivers,
including impacts from watershed processes, nutrient inputs, and changes in
ecosystem structure and metabolism.
However, the conditions predicted for the open ocean may not reflect the future conditions in the
coastal zone, where many of these organisms live (Hendriks et al. 2010a, b; Hofmann et al. 2011; Kelly and Hofmann 2012), and results derived from changes in pH in
coastal ecosystems often
include processes other than OA, such as emissions from volcanic vents, eutrophication, upwelling and long - term changes in the geological cycle of CO2, which commonly involve simultaneous changes in other key factors affecting the performance of calcifiers, thereby confounding the response expected from OA by anthropogenic CO2 alone.
This new concept of anthropogenic impacts on seawater pH formulated here accommodates the broad range of mechanisms involved in the anthropogenic forcing of pH in
coastal ecosystems,
including changes in land use, nutrient inputs,
ecosystem structure and net metabolism, and emissions of gases to the atmosphere affecting the carbon system and associated pH. The new paradigm is applicable across marine systems, from open - ocean and ocean - dominated
coastal systems, where OA by anthropogenic CO2 is the dominant mechanism of anthropogenic impacts on marine pH, to
coastal ecosystems where a range of natural and anthropogenic processes may operate to affect pH.

Alternative approaches
include using SRES scenarios as surrogates for some stabilisation scenarios (Swart et al., 2002; see Table 2.4), for example to assess impacts on
