The sediments found within the Carmel submarine canyon consist, for the most part, of poorly to very poorly sorted very fine sand and coarse silt. The shelf area surrounding the canyon is primarily comprised of moderately to very poorly sorted sand, with a small area of very poorly sorted gravel in the northeastern section of the bay. Consideration of textural parameters such as mean size, standard deviation, and skewness suggest that the sediments of the bay are under the influence of a dynamic sediment transport mechanisms. The bay appears to be a sedimentary system primarily isolated from adjacent coastal sediment sources, with the major sources of sedimentary deposits being terrigenous debris from the Carmel River, erosion and weathering of the local coastline and offshore rocks by wave and water and the shells and tests of numerous calcareous marine organisms. Movement of sediments by slumping and gravity sliding down the Carmel submarine canyon appears to be the only form of sediment removal within the bay." Purpose: "The objective of this study was to describe the distribution of the recent sediments of Carmel Bay, California."

Lineage: Process_Step: Process_Description: Grain-size analyses were conducted in accordance with the procedures outline in Krumbein and Pettijohn (1938). Grab samples were split to obtain a representative subsample of about 60 g. Three grabs samples (samples 10, 26, and 47) contained a large number of large pebbles, making splitting of the sample difficult. Therefore, each of these samples was analyzed in its entirety. The core was split lengthwise into two equal halves and four subsamples were taken. "Samples were washed in distilled water to desalt. Each subsample was then allowed to settle and the excess water decanted off. The subsample was then wet-sieved through a 4.0 phi screen to separate the sand and gravel-size fractions from the silt and clay-size fractions...."The dried coarse fraction was sieved at 0.5 phi intervals in a Ro-tap for 10 minutes, and weighed to the nearest 0.1 mg. Fine fraction (< 4.0 phi) were pipetted at 0.5 interval, except those samples which contained less than 5% of the total sample weight were dried and weighed directly. Statistics were computed using a program written by W. R. Anikouchine (Dinger, 1970), including Trask, Inman, and Folk and Ward values.
