Differential equity in access to public and private coastal infrastructure in the Southeastern United States
<p>Despite the ubiquity of coastal infrastructure, it is unclear what factors drive its placement, particularly for water access infrastructure (WAI) that facilitates entry to coastal ecosystems such as docks, piers, and boat landings. The placement of WAI has both ecological and social dimensions, and certain segments of coastal populations may have differential access to water. In this study, we employed an environmental justice framework to assess how public and private WAI in South Carolina, USA is distributed with respect to race and income. Using publicly available data from state agencies and the US Census Bureau, we mapped the distribution of these structures across the 301 km of the South Carolina coast. Using spatially explicit analyses with high resolution, we found that census block groups with lower income contain more public WAI, but racial composition has no effect. On the other hand, private docks showed the opposite trends, as the abundance of docks is significantly, positively correlated with census block groups that have greater percentages of White residents, while income has no effect. Under a "need-based" model of equity, we argue that WAI are not equitably distributed in South Carolina and constitute an environmental justice issue. We contend that the racially unequal distribution of docks is likely a consequence of the legacy of Black land loss, especially of waterfront property, throughout the coastal Southeast over the past half-century. Knowledge of racially inequitable distribution of WAI can guide public policy to rectify this imbalance and support advocacy organizations working to promote public water access. Our work also points to the importance of considering race in ecological research, as the spatial distribution of coastal infrastructure both directly affects ecosystems through the structures themselves and regulates which groups access water and what activities they can engage in at those sites.</p>
Data from: Rates and drivers of carbon emissions from hydropower reservoirs in the southeastern United States
<p>Reservoirs are a significant source of carbon (C) to the atmosphere, but their emission rates vary in space and time. We compared C emissions via diffusive and ebullitive pathways at several stations in six large hydropower reservoirs in the southeastern US that were previously sampled in summer 2012. We found that carbon dioxide (<span>CO<sub>2</sub></span>) diffusion was the dominant flux pathway during 2012 and 2022, with only three exceptions where methane (<span>CH<sub>4</sub></span>) diffusion or <span>CH<sub>4</sub></span> ebullition dominated. <span>CH<sub>4</sub></span> diffusion rates were positively associated with water temperature. However, we found no clear predictors of <span>CH<sub>4</sub></span> ebullition, which had extremely high variability, with rates ranging from 0 to 739 mg C m<sup>-2</sup> day<sup>-1</sup>. For <span>CO<sub>2</sub></span> diffusion, the direction of the flux shifted between 2012 and 2022, where all but three stations across all reservoirs emitted <span>CO<sub>2</sub></span> in summer 2012, but every station sequestered <span>CO<sub>2</sub></span> in summer 2022. Here, indicators of greater algal production were associated with <span>CO<sub>2</sub></span> sequestration, including surface chlorophyll-<em>a</em> concentration, surface dissolved oxygen saturation, and pH. Additional sampling campaigns outside the summer season highlighted the importance of seasonal phenology in primary production on the direction of <span>CO<sub>2</sub></span> diffusive fluxes, which shifted to positive <span>CO<sub>2</sub></span> fluxes by the end of August as productivity decreased. Our results demonstrate the importance of capturing <span>CO<sub>2</sub></span> sequestration in field and modelling measurements and understanding the seasonal drivers of these estimates. Measuring C emissions from multiple pathways in reservoirs and understanding their spatiotemporal responses and variability is vital to reducing uncertainties in global upscaling efforts.</p>
