Description

This dataset encapsulates all underway surface water data collected during BH15-11 in the western arm of Lake Superior.

Methods & Sampling

Dataset acquisition description

Underway surface sampling was collected aboard the RV Blue Heron during cruise BH15-11, which sailed from Duluth MN to Duluth MN during August 2015.

Data Processing Description

Dataset Processing Description

BCO-DMO Processing Notes:
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions

Instruments

Fluorometer

Supplied Name:

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.

pH Sensor

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: pH Sensor

Generic Description:

An instrument that measures the hydrogen ion activity in solutions.

The overall concentration of hydrogen ions is inversely related to its pH. The pH scale ranges from 0 to 14 and indicates whether acidic (more H+) or basic (less H+).

Photosynthetically Available Radiation Sensor

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: Photosynthetically Available Radiation Sensor

Acronym: PAR sensor

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/122/

Generic Description:

A PAR sensor measures photosynthetically available (or active) radiation. The sensor measures photon flux density (photons per second per square meter) within the visible wavelength range (typically 400 to 700 nanometers). PAR gives an indication of the total energy available to plants for photosynthesis. This instrument name is used when specific type, make and model are not known.

Transmissometer

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: Transmissometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/124/

Generic Description:

A transmissometer measures the beam attenuation coefficient of the lightsource over the instrument's path-length. This instrument designation is used when specific manufacturer, make and model are not known.

Water Temperature Sensor

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: Water Temperature Sensor

Acronym: Water Temp Sensor

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

Generic Description:

General term for an instrument that measures the temperature of the water with which it is in contact (thermometer).
