The goal is to establish an approach for integrating natural resource sensitivities with changes in physical conditions caused by wave energy converter arrays to inform planning and impact assessment. To generate the model inputs, a benthic substrate proxy within the project...

These self-healing additives have been evaluated in a broad range...

... zones can similarly induce heavy, accelerated microbiological pitting corrosion. The subsequent deterioration of the ferrous substrates leave these structures at risk for mechanical failure, as the effects of particle impact, abrasion, wear, and erosion combine with the weakened surface structure...

... amount to embrittle the substrate. For high strength steels, a post-plating hydrogen bake out is recommended by the industry to drive out the hydrogen and restore ductility. A literature search on the efficacy of a bake out for precipitation-hardened (PH) nickel alloys produced no results. Therefore...

... in the deep water GOM that are interpreted to be hard substrates suitable for benthic organisms. Where deep ocean currents are adequate to wash the fine hemipelagic mud off these carbonates, the latter becomes a clean, suitable substrate for benthic organisms. Unfortunately, 3-D seismic has a vertical sample...

Corrosion of the metal substrate, typically, will follow if not protected by an active cathodic electrical potential, chemical additives, or other means. Osmosis involves the transmission of single...
