Automatic titrator Supplied Name : Automatic titrator - T50, Mettler Toledo
Supplied Description :
In brief, TA (μmol kg− 1) was measured within 4 hours after sampling by potentiometric titration (T50, Mettler Toledo) using certified acid titrant.
Instrument Type
Generic Description :
Instruments that incrementally add quantified aliquots of a reagent to a sample until the end-point of a chemical reaction is reached.
Bottle Supplied Description :
Experiments 3 and 4, respectively, were conducted with 10 μm pre-filtered natural seawater and 10 μm pre-filtered sea water first incubated in 20 L bottles (bottle blooms).
Instrument Type
Generic Description :
A container, typically made of glass or plastic and with a narrow neck, used for storing drinks or other liquids.
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.
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.
Pump Supplied Name : Aquarium Pump
Supplied Description :
Bottle blooms were incubated in clear 20 L bottles at 14 °C, at 15–30 μE s − 1 for 12:12 hours and bubbled with an aquarium pump during the light hours to keep the carbonate system stable.
Instrument Type
Generic Description :
A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps
Roller Tank Supplied Description :
All experiments were conducted in rolling tanks at 14 °C in the dark.
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.
Spectrophotometer Supplied Name : Spectrophotometer - Shimadzu Biospec 16-1
Supplied Description :
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.
Turner Designs 700 Laboratory Fluorometer Supplied Name : TD-700
Supplied Description :
Chl. a was determined during growth of cultures and bottle blooms using a fluorometer (Turner 700) by filtration of samples onto 0.4 μm PC filters and soaking the filters in 90% acetone over night in the freezer (Strickland, 1972).
Instrument Type
Acronym : TD-700
Generic Description :
The TD-700 Laboratory Fluorometer is a benchtop fluorometer designed to detect fluorescence over the UV to red range. The instrument can measure concentrations of a variety of compounds, including chlorophyll-a and fluorescent dyes, and is thus suitable for a range of applications, including chlorophyll, water quality monitoring and fluorescent tracer studies. Data can be output as concentrations or raw fluorescence measurements.
