Methods & Sampling

Dataset acquisition description

This dataset was collected using the Benthic Ecosystem and Acidification Measuring System (BEAMS). The details of this technique and dataset can be found in the reference provided below (Takeshita et al. 2016), but are also summarized briefly here.

BEAMS uses autonomous sensors to quantify mean gradients of pH and O2 and the current velocity profile in the benthic boundary layer (BBL) to calculate benthic fluxes of O2 (NCP) and TA (NCC). The NCP and NCC provided here represent metabolic rates under completely natural (e.g. flow and light) conditions.

Data Processing Description

Dataset Processing Description

Questionable rates have been removed through a quality control procedure described in Takeshita et al. 2016. Briefly, 1) measurements when the benthic boundary layer was stratified were removed, and 2) Spikes in the data were removed based on the observed delta pH/ delta O2 relationship.

BCO-DMO Processing:
- replaced "NaN" with "nd" (no data);
- combined 2 datasets (one from each site) into one file;
- Added site lat/lon values from the metadata provided;
- Converted original Date_Time field to ISO_DateTime.

Supplied Description:

Instrument Type

Generic Name: Flow Meter

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/388/

Generic Description:

General term for a sensor that quantifies the rate at which fluids (e.g. water or air) pass through sensor packages, instruments, or sampling devices. A flow meter may be mechanical, optical, electromagnetic, etc.

Light Meter

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: Light Meter

Generic Description:

Light meters are instruments that measure light intensity. Common units of measure for light intensity are umol/m2/s or uE/m2/s (micromoles per meter squared per second or microEinsteins per meter squared per second). (example: LI-COR 250A)

Oxygen Sensor

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: Oxygen Sensor

Acronym: Dissolved Oxygen Sensor

Generic Description:

An electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analyzed

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+).
