Description

Thirty day time series of average daily phytoplankton concentration in the waters just seaward of the surf zone at Sand City, CA (36.615760 degrees N, 121.85485 degrees W).

Methods & Sampling

From 15 June to 15 July we sampled phytoplankton within the surf zone at about low tide each day and about 50 m seaward of the breaker line in the morning before the sea breeze strengthened making work from a small boat difficult. Offshore samples were collected a bit south of the sampled shoal and rip current. Outside the surf zone phytoplankton may have been stratified vertically. Here we sampled phytoplankton with a 25 um mesh plankton net. Replicate (n=3) vertical tows were made from the bottom to the surface. The amount of water filtered by the net was the depth of the tow times the area of the mouth of the net. Samples were preserved in acid Lugols. Phytoplankton were identified to genus and counted on Sedgwick Rafter slides using standard techniques (Sournia 1978).

Data Processing Description

Three samples were collected each day in the water over the ridges. Counts from the microscopic analysis of the samples were converted to number per liter and the average and 95% confidence interval for each daily set of samples were calculated.

BCO-DMO Processing:
- Re-formatted date, and added separate columns for month, day, year, and year-day.
- Added column containing site name.
- Added lat and lon (from metadata form).
- Modified parameter names to conform with BCO-DMO naming conventions.
- Replaced blanks (missing data) with 'nd' to indicate 'no data'.
