A., & Barry, D. (2013). Nearshore Drift-Cell Sediment Processes and
Ecological Function for Forage Fish: Implications for Ecological Restoration of
Impaired Pacific Northwest Marine Ecosystems. Journal Of Coastal Research,
29(4), 984-997. doi:10.2112/JCOASTRES-D-12-00264.1
In their article,
Parks and Barry discuss how the marine processes are a crucial role in the nearshore
ecosystem function. These marine processes include erosion, transport and
deposition because it forms suitable habitats for ‘forage’ fish spawning. The
authors further talk about how the disruption of the sediment through marine
processes has been assumed to result in an ‘impaired’ nearshore ecological
function. They examined the sediment characteristics of intertidal beaches of
three coastal drift cells, and then compared it to the metric of the forage
fish.

In this
article, authors Collins and Sitar conducted a five-year observational study of
the northern California coastline, particular San Francisco. They studied how
the sea and the cliffs interact to sculpt the major geomorphic processes such
as coastal bluff erosion and land-sliding. They define the coastal bluffs to be
weakly lithified sediment that undergoes continuous erosion, which could cause
an episodic landslide failure. Erosion is a primary aspect of marine processes
that also includes hydraulic action—when waves break at the foot of a cliff
that forces air in the cracks to be compressed—which could arguably be the
primary reason why there is the weakly lithified sediments.
