Methods & Sampling

From 15 June to 15 July we sampled phytoplankton 125 m offshore of the Carmel River State Beach. We also sampled phytoplankton 20 m offshore, just outside the breaker line, during the last 18 days (starting 28 June) of the time series. At the two offshore sites, samples were collected from a kayak in the morning when winds were light. Three replicate 1-L phytoplankton samples were collected from approximately 5 m depth using a stainless steel well sampling bailer. 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. 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.
- Created new column for distance offshore.
