AbstractCyber security tends to only address the technical aspects of the information systems. The lack of considerations for environmental long-range implications of failed cyber security planning and measures, especially in the protection of critical infrastructure and industrial control systems, have created ecological risks that are to a high degree unaddressed. This study compares dam safety arrangements in the United States and Sweden. Dam safety in the United States is highly regulated in many states, but inconsistent over the nation. In Sweden dam safety is managed by self-regulation. The study investigates the weaknesses and strengths in these regulatory and institutional arrangements from a cyber security perspective. If ecological and environmental concerns were a part of the risk evaluation and risk mitigation processes for cyber security, the hazard could be limited. Successful environmentally-linked cyber defense mitigates the risk for significant damage to domestic freshwater, aquatic and adjacent terrestrial ecosystems, and protects ecosystem function.

Inland water ecosystems dynamically process, transport, and sequester carbon. However, the transport of carbon through aquatic environments has not been quantitatively integrated in the context of terrestrial ecosystems. Here, we present the first integrated assessment, to our knowledge, of freshwater carbon fluxes for the conterminous United States, where 106 (range: 71–149) teragrams of carbon per year (TgC⋅y−1) is exported downstream or emitted to the atmosphere and sedimentation stores 21 (range: 9–65) TgC⋅y−1in lakes and reservoirs. We show that there is significant regional variation in aquatic carbon flux, but verify that emission across stream and river surfaces represents the dominant flux at 69 (range: 36–110) TgC⋅y−1or 65% of the total aquatic carbon flux for the conterminous United States. Comparing our results with the output of a suite of terrestrial biosphere models (TBMs), we suggest that within the current modeling framework, calculations of net ecosystem production (NEP) defined as terrestrial only may be overestimated by as much as 27%. However, the internal production and mineralization of carbon in freshwaters remain to be quantified and would reduce the effect of including aquatic carbon fluxes within calculations of terrestrial NEP. Reconciliation of carbon mass–flux interactions between terrestrial and aquatic carbon sources and sinks will require significant additional research and modeling capacity.
