Description

Concentration of pigments in phytoplankton, Particulate organic matter concentration, Macronutrients

One component of a Biological dataset collected from Southern Drake Passage and Scotia Sea

Ocean biology data were collected in Southern Drake Passage and Scotia Sea during two research cruises supported by NSF awards. These two cruises, namely LMG0402 and NBP0606, were conducted during Feb. to March 2004 and Jul. to Aug 2006, respectively. Dataset includes concentration of pigments in phytoplankton, particulate organic matter concentration, macronutrients, primary productivity and microbial biomass and productivity

As part of the data collection from the collaborative research, this dataset was for the study of plankton community structure and their response to the distribution and natural variability of dissolved iron in Southern Drake Passage and Scotia Sea

Methods & Sampling

Dataset acquisition description

Notes:

1. HPLC pigments samples were analyzed by CHORS/SDSU for LMG0402 and by HPL for NBP0606, respectively

2. Pigments not found by CHORS were given a concentration of 0; pigments not found by HPL were given a concentration of 0.0001

Instruments

CHN Elemental Analyzer

Supplied Description:

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.

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.

Liquid Scintillation Counter

Supplied Description:

Instrument Type

Generic Name: Liquid Scintillation Counter

Acronym: LSC

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB21/

Generic Description:

Liquid scintillation counting is an analytical technique which is defined by the incorporation of the radiolabeled analyte into uniform distribution with a liquid chemical medium capable of converting the kinetic energy of nuclear emissions into light energy. Although the liquid scintillation counter is a sophisticated laboratory counting system used the quantify the activity of particulate emitting (ß and a) radioactive samples, it can also detect the auger electrons emitted from 51Cr and 125I samples.

Liquid scintillation counters are instruments assaying alpha and beta radiation by quantitative detection of visible light produced by the passage of rays or particles through a suitable scintillant incorporated into the sample.

Nutrient Autoanalyzer

Supplied Description:

Instrument Type

Generic Name: Nutrient Autoanalyzer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB04/

Generic Description:

Nutrient Autoanalyzer is a generic term used when specific type, make and model were not specified. In general, a Nutrient Autoanalyzer is an automated flow-thru system for doing nutrient analysis (nitrate, ammonium, orthophosphate, and silicate) on seawater samples.
