Description

This dataset contains trace element concentrations from 2014 and 2015 in aerosols.

Methods & Sampling

Aerosol samples, integrated over a 24-hour period, were collected using a high-volume aerosol sampler (model 5170-VBL, Tisch Environmental, 1.2 m3 min-1) which pulls air through 12 replicate acid-washed 47 mm nitrocellulose filter disks (Whatman 41).

Instantaneous aerosol leaches (UHP-soluble) were conducted by the method described in Buck et al. (2010). Total aerosol digestions were conducted using a microwave digestion scheme described in Morton et al. (2013). All samples were analyzed on the Thermo Scientific Element 2 HR-ICP-MS.

These data were published in:

Ebling, A. M., & Landing, W. M. (2017). Trace elements in the sea surface microlayer: rapid responses to changes in aerosol deposition. Elem Sci Anth, 5(0), 42. doi: 10.1525/elementa.237

Data Processing Description

Data went through internal lab QAQC process. The spreadsheet uses BDL for below detection limit.

BCO-DMO Processing Notes:
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions
- nd (no data) was entered into all blank cells and NA cells.
- re-formatted date from m/d/yyyy HH:MM to yyyy-mm-ddTHHMM
- replaced spaces with underscores

Instruments

Aerosol Sampler

Supplied Name: Aerosol_Sampler

Supplied Description:

A device that collects a sample of aerosol (dry particles) from the atmosphere.

PI supplied instrument name: Aerosol Sampler

Dataset-specific description: High-volume Tish Environmental (model 5170-VBL) aerosol sampler.

Instrument Type

Generic Name: Aerosol Sampler

Acronym: Aerosol_Sampler

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/13/

Generic Description:

A device that collects a sample of aerosol (dry particles or liquid droplets) from the atmosphere.

Inductively Coupled Plasma Mass Spectrometer

Supplied Name: Thermo Scientific Element 2 HR-ICP-MS

Supplied Description:

All samples were analyzed on the Thermo Scientific Element 2 HR-ICP-MS.

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.
