JC, and 0.36 to 0.72 mm at WP. At .IC and WP , coarsest sediments occurred 

 during December or March; at GN , sediments were coarsest in September and 

 June. June sediments at GN and March sediments at WP were coarser than any 

 obtained since 1976. Although silt/clay (sediment > 0.06 mm) content and 

 organic matter were generally low at all stations, higher values were 

 generally obtained at JC. At WP and GN, silt/clay and organic matter were 

 often undetectable.

Sediment characteristics of the intertidal beaches during 1983 were 

 consistent with those observed in past years. At the more exposed stations 

 (GN and WP) , only slight within and between year changes in sediment 

 characteristics have occurred; this contrasts with the larger changes 

 observed at the less exposed JC station.
