“…The potential for adverse effects due to channel deepening in NY/NJ Harbor is not an isolated case, as other harbors now are being dredged to 14-15 m, and withdrawals of upstream river waters for drinking or industrial cooling purposes are likely to be affected by these changes as well as by rising sea-levels (cf., Shirazi et al, 2019). Nearly half a century ago, the potential effects of channel deepening on estuarine salinity distributions had been subject to preliminary investigation by the Army Corps for several US estuaries (Wicker, 1969;Brogdon, 1986).…”

Along the US Atlantic and Gulf coasts, port authorities and governments have been competing for access to federal funds to deepen the channels and berths in each of the major estuary-based harbors, thereby facilitating access by larger containerships. Consistent with a source-to-sea conceptualization, physical modifications of an estuary can result in dynamic changes to its water and sediment flows, resulting in new arrangements of environmental features. These modifications, in turn, can lead to redistributions of the net benefits arising from extant flows of valued ecosystem services to stakeholders and communities in the broader river-estuary system. Here, some of the implications of channel deepening in the Hudson river-estuary system were examined as a case study. An integrated analytical framework was developed, comprising hydrodynamic models of water flows and environmental characteristics, especially salinity; extreme value estimates of the occurrence of regional droughts; and assessments of the welfare effects of changes in ecosystem services. Connections were found among channel deepening in the lower estuary, increased risks to fluvial drinking water withdrawals in the upper estuary, and expected economic losses to hydropower generation in the upper river. The results argue for a more inclusive consideration of the consequences of human modifications of river-estuary systems.

“…The most relevant ones dealt with estuary management and observation of tidal systems (e.g., Stahl et al, 2018;Murray et al, 2019). These topics were entangled within a convoluted network spanning from the assessment of floodrelated risks (Broekx et al, 2011) to the economic impact of sea-level rise (Shirazi et al, 2019). "Environmental" topics were numerically relevant and conceptually broad, albeit not setting at the centre of the information-flow (see pink, green and blue nodes in Figure 2), which was occupied by a topical group head by "coastal, " "wetland, " and "quantify" (orange nodes in Figure 2).…”

Intersecting Ecosystem Services Across the Aquatic Continuum: From Global Change Impacts to Local, and Biologically Driven, Synergies and Trade-Offs

The study of ecosystem services requires the integration of different observational points. This is particularly true in Water, as this element continuously cycles, increasing chances of interaction among services originating in different ecosystems. However, aquatic scientists historically approached the study of inland/freshwater and open/marine waters in different ways and this cultural division potentially hampers integrative approaches. Herein, we explored the literature pertaining to ecosystem services across the last 23 years, analysing 4,590 aquatic papers. By aggregating and intersecting topics included in this papers’ collection using text-mining and topical network approaches, we saw that the study of local environmental conditions (e.g., river estuary management) and synergies and trade-offs between services (e.g., carbon sequestration and water purification) can display several potential conceptual links between freshwater and marine sciences. Our analyses suggest that to intersect ecosystem services across the aquatic continuum, the conceptual integration between marine and freshwater science must be reinforced, especially at the interface between different “salinity realms.” Such integration should adopt a “system thinking” perspective, in which the focus is on multiple socio-ecological processes giving rise to interactions that are (i) biologically mediated, (ii) potentially conflicting, and (iii) entangled within networks.
