The filters for POC and PON were fumed to remove inorganic carbon and analyzed at the Analytical Laboratory of the Marine Science Institute at UCSB using an elemental analyzer (CEC 44OHA by Control Equipment Corp).
Instrument Type
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.
Conductivity Meter Supplied Name : Conductivity Meter - 3100 Yellow Springs Instruments
Supplied Description :
Salinity was determined from TA samples using a conductivity instrument (3100 Yellow Springs Instruments)
Instrument Type
Generic Description :
Conductivity Meter - An electrical conductivity meter (EC meter) measures the electrical conductivity in a solution. Commonly used in hydroponics, aquaculture and freshwater systems to monitor the amount of nutrients, salts or impurities in the water.
Flow Injection Analyzer Supplied Name : Flow Injection Analyzer - QuickCem 8000, Lachat Instruments
Supplied Description :
Concentrations of NO3+NO2, PO4 and Si(OH)4 in the initial phytoplankton-detritus mixture were measured by simultaneous flow injection analysis (QuickCem 8000, Lachat Instruments) in the Analytical Laboratory of the Marine Science Institute at UCSB from pre-filtered frozen samples.
Instrument Type
Acronym : FIA
Generic Description :
An instrument that performs flow injection analysis. Flow injection analysis (FIA) is an approach to chemical analysis that is accomplished by injecting a plug of sample into a flowing carrier stream. FIA is an automated method in which a sample is injected into a continuous flow of a carrier solution that mixes with other continuously flowing solutions before reaching a detector. Precision is dramatically increased when FIA is used instead of manual injections and as a result very specific FIA systems have been developed for a wide array of analytical techniques.
In-situ incubator Supplied Name : in-situ incubator
Supplied Description :
Instrument Type
Acronym : in-situ incubator
Generic Description :
A device on a ship or in the laboratory that holds water samples under controlled conditions of temperature and possibly illumination.
Microscope - Optical Supplied Name : Dissecting Microscope
Supplied Description :
The length and width of each aggregate were measured to the nearest mm under a dissecting scope.
Instrument Type
Generic Description :
Instruments that generate enlarged images of samples using the phenomena of reflection and absorption of visible light. Includes conventional and inverted instruments. Also called a "light microscope".
Nutrient Autoanalyzer Supplied Name : Nutrient Autoanalyzer - TRAACS CS800 autoanalyzer
Supplied Description :
DIC was measured colorimetrically in duplicate with a TRAACS CS800 autoanalyzer (Seal, Mequon, USA) with a precision of ± 5 μmol kg-1. CRM (Batch No. 54) supplied by A. Dickson was used as a calibration (see for methodological details).
Instrument Type
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.
Roller Tank Supplied Description :
Roller tanks experiments: 14 cylindrical five-liter roller tanks/ treatments rotating at 1 rpm encompassing three acidification scenarios and 5 concentrations of the clay illite incubated at 14oC in continuous darkness for 44 to 48 hours. Solid body rotation was established within three hours.
Instrument Type
Generic Description :
Rolling tanks, which keep particles in suspension, thus simulating aggregate formation in situ.
Marine snow experiments are conducted in roller tanks, which turn continuously, keeping marine snow in suspension. It is important for marine snow not to touch surfaces. The rolling tanks, which keep particles in suspension, thus simulate aggregate formation in situ. Marine snow formation due to different types of oil was tested. Some treatments are easily identifiable as containing oil by their color (middle). UCSB, CA 2012.
Shimadzu TOC-V Analyzer Supplied Name : Shimadzu TOC-V
Supplied Description :
The filtered samples were immediately frozen at -20°C and later analyzed via high temperature combustion on a modified Shimadzu TOC-V analyzers in the Carlson lab at UCSB.
Instrument Type
Acronym : Shimadzu TOC-V
Generic Description :
A Shimadzu TOC-V Analyzer measures DOC by high temperature combustion method.
Spectrophotometer Supplied Name : Genesys 10SVIS Spectrophotometer
Supplied Description :
The samples for pHT were collected bubble free in 20-ml scintillation vials and measured within 1-2 hours of sampling with a spectrophotometer (Genesys 10SVIS) equipped with a single cell Peltier (SPG1A, both Thermo Scientific) using the indicator dye m-cresol purple (Sigma-Aldrich) at a constant temperature of 25oC.
Instrument Type
Generic Description :
An instrument used to measure the relative absorption of electromagnetic radiation of different wavelengths in the near infra-red, visible and ultraviolet wavebands by samples.
