Bay in St. Andrews State Park; transect 2 is 30.5 meters east of the pier 

 in St. Andrews State Park; transect 3 is offshore of the intersection of 

 Lookout Street and Spyglass Street; transect 4 is offshore of the Holiday 

 Inn West; transect 5 is offshore of the Fiesta Motel; transect 6 is off- 

 shore of the Fountainbleau Terrace Motel; transect 7 is offshore of the 

 Sunnyside Motel; transect 8 is offshore of the Roundtower Motel; and 

 transect 9 is offshore of Pinnacle Port. The motel names for transects 4 

 and 6 were reversed in Saloman (1976) . 



In addition to the 47 stations, 2 borrow sites that were dredged in 

 July and August 1976, but have since filled in, were also sampled. Borrow 

 site Bl is located about 6.4 kilometers southeast of Laguna Beach, offshore 

 of the Ambassador Motel, 183 meters from Highway 98 in about 6.1 meters of 

 water. The site is rectangular, 152 by 23 meters, and parallel to the 

 beach. Borrow site B2 is located about 2.4 kilometers southeast of Laguna 

 Beach in front of the Peppertree Motel (abandoned), 274 meters offshore 

 of Highway 98 in about 6.1 meters of water. The site is rectangular, 229 

 by 128 meters, and is oriented diagonally to the shoreline. Stations CA 

 and CB served as control stations for the borrow sites. 



II. MATERIALS AND METHODS 



1. Physical Parameters . 



Temperature (in Celsius) , dissolved oxygen Cin parts per million), 

 and conductivity (in micromhos per centimeter) were measured at each station 

 with a Hydrolab in situ physicochemical monitor. Where water depth was 

 sufficient, readings were taken 0.5 meter below the surface as well as 

 0.5 meter above the bottom. Logbook entries for conductivity were corrected 

 for temperature and converted to salinity Cin parts per thousand) . Dissolved 

 oxygen readings were corrected for salinity. 



2. Topography . 



Using standard surveying techniques, beach profiles were constructed 

 for each of the nine transect sites. Beginning landward at the surveying 

 monuments, the profiles extended seaward to wading depth. 



3. Sediment Characteristics . 



At each station two sediment samples were taken with a 5.08-centimeter- 

 diameter polyvinylchloride (PVC) core. The cores were inserted 10 to 15 

 centimeters into the substratum, removed and both ends corked. The samples 

 were then transferred to 454-milliliter plastic jars with internal and 

 external labels, frozen, and stored until analyzed. One sample from each 

 station was processed for grain size, organic content, and carbonate con- 

 tent. The second sample served as a backup. 



Laboratory analysis of sediment samples is schematically shown in 

 Figure 2. Details of the procedures are as follows:
