... Sea varied in size and flow direction in McMurdo Sound during the last glacial period ( Anderson et al., 2017 ; Wilson, 2000 ). Wilson (2000) suggested that fossiliferous Eocene erratics in Ross Sea drift indicated expansion of local alpine glaciers during the LGM. Anderson et al. (2017) built...

.... Army Corps of Engineers developed a plan for the groin field, and their recommendation was to sequentially build the groins up drift (eastward toward Shinnecock Inlet) using standard project design. However, in the late 1970s, local community pressure forced the U.S. Army Corps of Engineers, contrary...

Gravel-dominated beds represent deposition of reworked rockfall debris and glacial drift by cohesionless debris flows, whereas finer-grain beds are probably the result of sheet-flows derived by washout of fines from debris-flow deposits.
