Methods & Sampling

Pyrosomes (Pyrosoma atlanticum) were picked out of zooplankton catches, counted and measured for total colony length (mm) and then frozen at -80˚C for subsequent analysis of gut pigment content following the gut fluorescence technique. Details of sampling and analytical procedures can be found in O’Loughlin et al. (2020).

Data Processing Description

BCO-DMO Processing:
- concatenated data from two separate cruise files into one dataset;
- changed date format to YYYY-MM-DD;
- re-named fields;
- rounded values to three decimal places.

Instruments

Bongo Net

Supplied Name: Bongo net

Supplied Description:

Instrument Type

Generic Name: Bongo Net

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/NETT0009/

Generic Description:

A Bongo Net consists of paired plankton nets, typically with a 60 cm diameter mouth opening and varying mesh sizes, 10 to 1000 micron. The Bongo Frame was designed by the National Marine Fisheries Service for use in the MARMAP program. It consists of two cylindrical collars connected with a yoke so that replicate samples are collected at the same time. Variations in models are designed for either vertical hauls (OI-2500 = NMFS Pairovet-Style, MARMAP Bongo, CalVET) or both oblique and vertical hauls (Aquatic Research). The OI-1200 has an opening and closing mechanism that allows discrete "known-depth" sampling. This model is large enough to filter water at the rate of 47.5 m3/minute when towing at a speed of two knots. More information: Ocean Instruments, Aquatic Research, Sea-Gear

Fluorometer

Supplied Name: Turner Designs Trilogy

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.
