Description

These data are published in Hirsh et al., see related publications section.

Methods & Sampling

Nighttime surface chlorophyll-a concentrations (μg/L) at the OA1 Buoy (operated by MBARI) during the mooring deployment period, June 7 to October 4, 2018. Francisco Chavez and the Biological Oceanography Group at MBARI provided the chlorophyll a fluorescence data from the OA 1 buoy.

Data Processing Description

The factory calibration was used to convert fluorescence to chlorophyll a concentrations without further modification. Daytime chlorophyll a concentrations were removed to avoid bias in the data from non-photochemical quenching.

BCO-DMO processing notes:

Converted Timestap to ISO format, and timezone from Pacific Standard Time (PST) to UTC
Added latitude and longitude of sampling location

Supplied Name: WETStar Fluorometer

Supplied Description:

Instrument Type

Generic Name: Fluorometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/113/

Generic Description:

A fluorometer or fluorimeter is a device used to measure parameters of fluorescence: its intensity and wavelength distribution of emission spectrum after excitation by a certain spectrum of light. The instrument is designed to measure the amount of stimulated electromagnetic radiation produced by pulses of electromagnetic radiation emitted into a water sample or in situ.

Parameters

Date and time formats are described in python strftime() syntax.
