Phillips, M. (2008). Beach erosion and marine aggregate dredging: a question of evidence? Geographical Journal, 174(4), 332-343. doi:10.1111/j.1475-4959.2008.00306.x

Phillips talked about how erosion, particularly coastal erosion (one of the marine processes), has continued to be a problem around the world, especially for the European Union Member States. He argued how marine aggregated dredging has increased the amount of erosion that would otherwise be natural from sea. Phillips compares the data from natural beach erosion to the effects of the erosion from marine aggregated dredging.

Odnevall Wallinder, I., Zhang, X., Goidanich, S., Le Bozec, N., Herting, G., & Leygraf, C. (2014). Corrosion and runoff rates of Cu and three Cu-alloys in marine environments with increasing chloride deposition rate. Science Of The Total Environment, 472681-694. doi:10.1016/j.scitotenv.2013.11.080

In this article, the authors discuss how there are decreasing corrosion rates with decreasing chloride load for all materials. They studied the various minerals of  Cu-based alloys, Cu15Zn, Cu4Sn and Cu5Al5Zn and bare copper sheets at four test sites in Brest, France. Corrosion and deposition is part of the marine processes. They observed how the corrosion rates for all these materials have decreased as they move away from the coast. Deposition is when there are energy level decreases in environments. Additionally, there is the atmospheric corrosion of Cu, Cu15Zn, Cu4Sn and Cu5Al5Zn  at declining coastal distance. There is a significantly lower rate of the amount of what is called ‘release’ compared to the corrosion rates.
