Description

Daily Chlorophylla (ug/L) data from surface waters off of the Santa Monica Pier, California from April 13th to May 5th 2019 as part of the San Pedro Ocean Time-series (SPOT).

Methods & Sampling

Chlorophyll Extraction by Non-Acidification Method
Whole seawater collected from Santa Monica Pier, CA by bucket off pier. Portion of whole seawater placed in dark for chlorophyll processing. Bottle shaken, then filtered on to GFF filter (Glass Microfiber Filter, 0.7um, 25mm,Whatman) using tower rig and gast pump vacuum. Triplicates taken for each day. Wrapped in foil and flash frozen in liquid nitrogen to preserve. Stored in lab in -80C freezer till processed.
In Lab processing: using glass cuvette (Disposable Culture Tubes, Borosilicate Glass, 12x75mm, VWR), place individual filter inside, add 4ml 100% Acetone, and cap. Ensure filter is submerged in acetone. Wrap all samples in foil and place in -20C freezer for 18-24hr. Between 18-24hrs remove samples and thaw for 30 minutes, keep in dark. Using Turner Design Fluorometer, calibrate using stored standard. For samples, invert sample multiple times, uncap, using metal spatula remove filter, use Kimwipe to clean off outside of cuvette, place in fluorometer and record both raw fluoresce and direct concentration. Dilution may be necessary if raw fluoresce is above 250 RFU.

Data Processing Description

Chlorophyll data was processed in Microsoft Word Excel 2011, for calibration correction on samples and averaging triplicate values.

Instruments

Turner Designs 700 Laboratory Fluorometer

Supplied Name: Turner Design Instruments Model# 7200-000

Supplied Description:

Instrument Type

Generic Name: Turner Designs 700 Laboratory Fluorometer

Acronym: TD-700

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0510/

Generic Description:

The TD-700 Laboratory Fluorometer is a benchtop fluorometer designed to detect fluorescence over the UV to red range. The instrument can measure concentrations of a variety of compounds, including chlorophyll-a and fluorescent dyes, and is thus suitable for a range of applications, including chlorophyll, water quality monitoring and fluorescent tracer studies. Data can be output as concentrations or raw fluorescence measurements.
