“…Exposure is the second component of species vulnerability and has been defined by ecosystem exposure to environmental change (Metzger et al, 2005;Halpern et al, 2008;Okey et al, 2015), expert opinion (Teck et al, 2010;Hare et al, 2016) and economic risk (Mathis et al, 2015). We calculated exposure as a function of intertidal elevation to determine which taxa are likely to be most physically exposed to OA.…”

“…Several studies have approached the quantification of coastal exposure at varying degrees of resolution (Mathis et al, 2015;Okey et al, 2015;Hare et al, 2016;Marshall et al, 2017); however, no studies to date have focused exclusively on intertidal exposure parameters, though Wootton et al (2008) examined some parameters related to pH exposure in the intertidal zone. Notable differences in literature estimations of exposure result from the definition of exposure (i.e., physical, commercial, or anthropocentric), and idiosyncratic differences between marine habitats (i.e., pelagic, benthic, intertidal).…”

“…There is good reason to study organisms of high economic importance or anticipated sensitivity to better understand the overall impact of OA on marine systems, but there is also a need for resource managers to better understand the effects of OA for the specific regions they manage. Examples of place-based analyses exist for determining vulnerability derived from habitats (Okey et al, 2015), state delineated fisheries (Mathis et al, 2015), and marine ecosystems (Teck et al, 2010) to better forecast OA effects for a region of interest. These evaluations take into account details of local geography to identify factors that may compound inherent organism risk.…”

“…Organisms of high economic value (Barton et al, 2015;Mathis et al, 2015;Ou et al, 2015;Richards et al, 2015) or those characterized by high a priori sensitivity due to vulnerable life stages (Barton et al, 2012;Cooley et al, 2012) have been studied disproportionately more than those that may have more surreptitious sensitivities (e.g., metabolic pH imbalance). Furthermore, a select number of organisms, such as pteropods (Bednaršek et al, 2017) and oysters (Waldbusser et al, 2011;Barton et al, 2012), have received closer examination due to their role as bellwethers for OA-derived impacts.…”

Ocean acidification (OA) will have a predominately negative impact on marine animals sensitive to changes in carbonate chemistry. Coastal upwelling regions, such as the Northwest coast of North America, are likely among the first ecosystems to experience the effects of OA as these areas already experience high pH variability and naturally low pH extremes. Over the past decade, pH off the Olympic coast of Washington has declined an order of magnitude faster than predicted by accepted conservative climate change models. Resource managers are concerned about the potential loss of intertidal biodiversity likely to accompany OA, but as of yet, there are little pH sensitivity data available for the vast majority of taxa found on the Olympic coast. The intertidal zone of Olympic National Park is particularly understudied due to its remote wilderness setting, habitat complexity, and exceptional biodiversity. Recently developed methodological approaches address these challenges in determining organism vulnerability by utilizing experimental evidence and expert opinion. Here, we use such an approach to determine intertidal organism sensitivity to pH for over 700 marine invertebrate and algal species found on the Olympic coast. Our results reinforce OA vulnerability paradigms for intertidal taxa that build structures from calcium carbonate, but also introduce knowledge gaps for many understudied species. We furthermore use our assessment to identify how rocky intertidal communities at four long-term monitoring sites on the Olympic coast could be affected by OA given their community composition. the park's general management plan (NPS, 2007). The 65-mile coastline is a UNESCO Biosphere Reserve and World Heritage Site that hosts one of the most biodiverse assemblages of marine invertebrates and seaweeds along the west coast of North America (Schoch et al., 2006). The intertidal zone is comprised of rocky reefs, sandy beaches, and cobble boulder fields and is valued regionally and nationally for its ecological, economic, and cultural significance. The loss of species in the intertidal zone that rely on a particular pH threshold or the availability of CO 3 2− could fundamentally alter one or all of these interests (Cooley et al., 2009;Lynn et al., 2013) and have resounding reverberations for marine food webs (Gaylord et al., 2015). Over the past decade, ocean pH off the Olympic coast has declined an order of magnitude faster than predicted by accepted conservative climate change models (Feely et al., 2004;Wootton and Pfister, 2012) and has impacted marine aquaculture in the region (Barton et al., 2015). These observations spurred the Governor of Washington to form a Blue Ribbon Panel on Ocean Acidification. The panel's report (Washington Department of Ecology, 2012) recommended expanded pH monitoring and an assessment of marine resource sensitivity to OA. Although OA-associated impacts are documented for several cosmopolitan species, a major limitation for resource managers is determining how those impacts will be experience...

“…Model-based studies have estimated the potential costs of ocean acidification impacts to shellfish harvests in the US at $75-187 million a year , global shellfish harvests at $6 billion a year (Narita et al, 2012), and coral reef impacts at $0-900 billion a year (Brander et al, 2009). Recent studies have begun exploring ocean acidification's threat to human communities with risk assessment frameworks (Cooley et al, 2012;Ekstrom et al, 2015;Mathis et al, 2015), which shed light not only on the areas at greater total risk, but also on the characteristics of the socioeconomic system that contribute to this risk.…”

The Importance of Freshwater to Spatial Variability of Aragonite Saturation State in the Gulf of Alaska

et al. 2017

High‐latitude and subpolar regions like the Gulf of Alaska (GOA) are more vulnerable than equatorial regions to rising carbon dioxide (CO2) levels, in part due to local processes that amplify the global signal. Recent field observations have shown that the shelf of the GOA is currently experiencing seasonal corrosive events (carbonate mineral saturation states Ω, Ω < 1), including suppressed Ω in response to ocean acidification as well as local processes like increased low‐alkalinity glacial meltwater discharge. While the glacial discharge mainly influences the inner shelf, on the outer shelf, upwelling brings corrosive waters from the deep GOA. In this work, we develop a high‐resolution model for carbon dynamics in the GOA, identify regions of high variability of Ω, and test the sensitivity of those regions to changes in the chemistry of glacial meltwater discharge. Results indicate the importance of this climatically sensitive and relatively unconstrained regional freshwater forcing for Ω variability in the nearshore. The increase was nearly linear at 0.002 Ω per 100 µmol/kg increase in alkalinity in the freshwater runoff. We find that the local winds, biological processes, and freshwater forcing all contribute to the spatial distribution of Ω and identify which of these three is highly correlated to the variability in Ω. Given that the timing and magnitude of these processes will likely change during the next few decades, it is critical to elucidate the effect of local processes on the background ocean acidification signal using robust models, such as the one described here.
