Abstract: Origin and Distribution of Suspended Sediments in Previous HitBayNext Hit of Fundy, Canada

James A. Miller

The Previous HitBayNext Hit of Fundy lies between Nova Scotia and New Brunswick on the Atlantic coast of Canada. The Previous HitbayNext Hit is trough-shaped and deepens seaward, with the head of the Previous HitbayNext Hit splitting into two smaller embayments known as Chignecto Previous HitBayNext Hit and the Minas Basin.

The coastal erosion rate in Chignecto Previous HitBayNext Hit and the Minas Basin is more than 1.8 m/year, and is the major source for the detrital-suspended sediments. Suspended sediment concentrations range from 0.2 to 30.4 mg/l. Suspended sediment concentration increases from the mouth to the head of the Previous HitbayNext Hit, from the Nova Scotia to the New Brunswick side of the Previous HitbayNext Hit, and generally with increasing depth in the water column.

Highly turbid water from Chignecto Previous HitBayNext Hit and Minas Basin mixes with the less turbid water in the main Previous HitbayNext Hit, and gradually is moved along the New Brunswick shore toward the mouth of Fundy. However, a certain percentage of the suspended sediment load is deposited permanently in the Minas Basin, Chignecto Previous HitBayNext Hit, and along the New Brunswick side of the main Previous HitbayNext Hit. Shallow-seismic work has shown that more than 40 m of post-Pleistocene sediment is present in parts of Chignecto Previous HitBayNext Hit and along much of the New Brunswick side of the main Previous HitbayNext Hit. Similar thicknesses of post-Pleistocene sediments also are present at the mouth of the Previous HitBayTop of Fundy and in parts of the Gulf of Maine.
