Expand/Collapse All

Description

SOIREE Underway fluorescence, FRRF (Fv/Fm)

Includes values for surface PAR obtained from Mark Gall

The data are sampled at the times when the Fv/Fm was measured

The data are presented in a raw, uncalibrated form.

Missing data are marked by "nd".

Methods & Sampling

See SOIREE Preliminary Voyage Report
See comments in dataset description as well

A Chelsea instruments CTD/Fluorometer was mounted in a chamber that was supplied with

flow-through sea-water. From this instrument Temperature and Fluorescence were logged.

A Chelsea Instruments Fasttracka FRRF was used to record phytoplankton photosynthetic

competency (Fv/Fm).

BCO-DMO Edits

- Parameter names modified to conform to BCO-DMO convention

- date reformatted to YYYYMMDD

- time reformatted to HHMM

- Note: Some times with 59 seconds truncated when fmtted for BCO-DCO

- 'NaN' changed to 'nd'

- data values padded to 2 decimal places

- lat/lon merged from ship's track data

Instruments

CTD-FRRfluorometer

Supplied Name: CTD/Fluorometer

Supplied Description:

Chelsea instruments CTD/Fluorometer was used to log Temperature and Fluorescence

Instrument Type

Generic Name: CTD-FRRfluorometer

Acronym: CTD-FRRf

Generic Description:

A CTD-FRRf fluorometer is an instrument package designed to measure hydrographic information (pressure, temperature and conductivity) and chlorophyll fluorescence. (see more at URL: http://www.chelsea.co.uk/Instruments%20FASTtracka.htm) For example, a Chelsea FASTtracka CTD (conductivity, temperature, and depth) device can be configured with additional sensors to measure fluorescence and photosynthetically active radiation (PAR) in the water column. Fluorescence data collected by the CTD are subsequently calibrated and corrected to give the average concentration of chlorophyll a in the water column. The Chelsea system can be configured as part of a towed package or in a shipboard pumping system.

Fast Repetition Rate Fluorometer

Supplied Name: Fast Repetion Rate Fluorometer

Supplied Description:

A Chelsea Instruments Fasttracka FRRF was used to record phytoplankton photosynthetic
competency (Fv/Fm)

Instrument Type

Generic Name: Fast Repetition Rate Fluorometer

Acronym: FRRf

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

Generic Description:

An FRRf is used for measuring the fluorescence of a sample of phytoplankton photosynthetic competency (Fv/Fm).
