Description

USGS Arctic Ocean Carbon Cruise 2012: Metals Data
Trace metal data from the HLY 1202 cruise

Methods & Sampling

The sample bottle (60 ml Nalgene) was rinsed with seawater three times immediately before sampling and then filled with sample water. Six drops of 5% trace metal grade HNO3- was added to the sample. The container was capped and frozen. Samples were analyzed for trace metals using an ICP-MS located at the University of South Florida College of Marine Science.

Samples were numbered incrementally throughout the duration cruises. A single number (e.g. 1) indicates a sample taken from the ship's flow-through system. A two-number code indicates a sample taken from a rosette sampler at a vertical profile station and consists of the station number followed by the bottle number (e.g. 3_5 indicates station 3, bottle 5.)

Instruments

CTD Sea-Bird SBE 911plus

Supplied Name: CTD SBE 911plus

Supplied Description:

Discrete samples from vertical profile casts were collected at 4 locations. A 24-bottle Niskin rosette (12-L bottle volume) with an electronic trigger was fitted with a Sea-Bird SBE 911plus CTD and altimeter.

Instrument Type

Generic Name: CTD Sea-Bird SBE 911plus

Acronym: CTD SBE 911plus

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0058/

Generic Description:

The Sea-Bird SBE 911 plus is a type of CTD instrument package for continuous measurement of conductivity, temperature and pressure. The SBE 911 plus includes the SBE 9plus Underwater Unit and the SBE 11plus Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 plus and SBE 11 plus is called a SBE 911 plus. The SBE 9 plus uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 plus and SBE 4). The SBE 9 plus CTD can be configured with up to eight auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.). more information from Sea-Bird Electronics

Inductively Coupled Plasma Mass Spectrometer

Supplied Name: ICP Mass Spec

Supplied Description:

Samples were analyzed for trace metals using an ICP-MS located at the University of South Florida College of Marine Science.

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.

Niskin bottle

Supplied Description:

Instrument Type

Generic Name: Niskin bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0412/

Generic Description:

A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.

Pump - Surface Underway Ship Intake

Supplied Name: pump-ship intake

Supplied Description:

Samples were numbered incrementally throughout the duration cruises. A "surface" prefix indicates a sample taken from the ship's flow-through system.

Instrument Type

Generic Name: Pump - Surface Underway Ship Intake

Acronym: Pump-Ship Intake

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/31/

Generic Description:

The 'Pump-underway ship intake' system indicates that samples are from the ship's clean water intake pump. This is essentially a surface water sample from a source of uncontaminated near-surface (commonly 3 to 7 m) seawater that can be pumped continuously to shipboard laboratories on research vessels. There is typically a temperature sensor near the intake (known as the hull temperature) to provide measurements that are as close as possible to the ambient water temperature. The flow from the supply is typically directed through continuously logged sensors such as a thermosalinograph and a fluorometer. Water samples are often collected from the underway supply that may also be referred to as the non-toxic supply. Ideally the data contributor has specified the depth in the ship's hull at which the pump is mounted.

Sea-Bird SBE 45 MicroTSG Thermosalinograph

Supplied Name: SBE 45 MicroTSG

Supplied Description:

Salt content in Practical Salinity Units measured using the USCGC Healy's SBE45 instrument for surface samples and the SBE9 for station (depth) samples.

Instrument Type

Generic Name: Sea-Bird SBE 45 MicroTSG Thermosalinograph

Acronym: SBE 45 MicroTSG

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0190/

Generic Description:

A small externally powered, high-accuracy instrument, designed for shipboard determination of sea surface (pumped-water) conductivity and temperature. It is constructed of plastic and titanium to ensure long life with minimum maintenance. It may optionally be interfaced to an external SBE 38 hull temperature sensor.

Sea-Bird SBE-3 Temperature Sensor

Supplied Name: SBE-3 Temperature

Supplied Description:

Seawater Surface Temperature degrees Celsius measured using the USCGC Healy's SBE3 remote temperature probe

Instrument Type

Generic Name: Sea-Bird SBE-3 Temperature Sensor

Acronym: SBE-3 Temperature

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/134/

Generic Description:

The SBE-3 is a slow response, frequency output temperature sensor manufactured by Sea-Bird Electronics, Inc. (Bellevue, Washington, USA). It has an initial accuracy of +/- 0.001 degrees Celsius with a stability of +/- 0.002 degrees Celsius per year and measures seawater temperature in the range of -5.0 to +35 degrees Celsius. more information from Sea-Bird Electronics
