Description

Concentrations of C, N, P and trace metals in zooplankton size fractions from the MV1008 cruise to the Costa Rica Upwelling Dome.

Methods & Sampling

Dataset acquisition description

Samples were collected as splits from the zooplankton biomass tows conducted by Mike Landry's group on the FluZIE cruise (MV1008) and archived in association with that data. Zooplankton were size fractionated onto nitex nets. Size fractions were then transferred to 47mm filter tower fitted with a 0.2 um membrane. They were then rinsed with a sodium oxalate solution to remove metal adsorbed to external surfaces. Samples were then frozen in 2 mL centrifuge tubes and freeze dried at Stony Brook. Carbon and nitrogen per unit dry weight was determined with a CNH analyser and phosporus was determined with the acid molybdate method after ashing. Trace metal content per dry weight was determined by ICP-MS by Benjamin Twining at Bigelow Laboratory.

Data Processing Description

Dataset Processing Description

The data are presented as simple means of samples for some stations collected during a transect (TYPE=Transect), and for day and night samples collected during 4 drifter studies (TYPE + Cycles 1, 2, 3, 4), each of which lasted 4 days.

BCO-DMO edits:
- Changed formatting of date and time columns;
- Modified parameter names to conform with BCO-DMO naming conventions;
- Replaced blank values with 'nd' to indicate 'no data';
- Added size_fract_min and size_fract_max columns.

Instruments

CHN Elemental Analyzer

Supplied Name: CNH analyser

Supplied Description:

Carbon and nitrogen per unit dry weight was with a CNH analyser.

Instrument Type

Generic Name: CHN Elemental Analyzer

Acronym: CHN_EA

Generic Description:

A CHN Elemental Analyzer is used for the determination of carbon, hydrogen, and nitrogen content in organic and other types of materials, including solids, liquids, volatile, and viscous samples.

Inductively Coupled Plasma Mass Spectrometer

Supplied Name: ICP-MS

Supplied Description:

Trace metal content per dry weight was determined by ICP-MS by Benjamin Twining at Bigelow Laboratory.

Instrument Type

Generic Name: Inductively Coupled Plasma Mass Spectrometer

Acronym: ICP Mass Spec

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB15/

Generic Description:

An ICP Mass Spec is an instrument that passes nebulized samples into an inductively-coupled gas plasma (8-10000 K) where they are atomized and ionized. Ions of specific mass-to-charge ratios are quantified in a quadrupole mass spectrometer.

Ring Net

Supplied Description:

Mesozooplankton sampling was conducted using a standard 1-m2 ring net with 202-um Nitex mesh, towed obliquely for 20 minutes at a ship speed of 1-2 kts.

Instrument Type

Generic Name: Ring Net

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/22/

Generic Description:

A Ring Net is a generic plankton net, made by attaching a net of any mesh size to a metal ring of any diameter. There are 1 meter, .75 meter, .25 meter and .5 meter nets that are used regularly. The most common zooplankton ring net is 1 meter in diameter and of mesh size .333mm, also known as a 'meter net' (see Meter Net).
