Description

Methods & Sampling

Dataset acquisition description

At each of 15 sites, a 50m transect was laid out along the depth contour. Ten-meter segments were processed, equating to five 10m transects per site. The beginning and end points of transects were marked underwater and the transects were revisited three times within one year.

The benthic composition was assessed using the Point Intercept Method, whereby the substrate immediately below the transect line was identified every 0.5m along five 10m transects. Standard categories of benthic composition included both living and abiotic components.

Data Processing Description

Dataset Processing Description

BCO-DMO Processing:

- added conventional header with dataset name, PI name, version date
- renamed parameters to BCO-DMO standard
- replaced data_recorder = UNK with unknown
- added site, zone, lat and lon columns
- reformatted date from m/d/yyyy to yyyy-mm-dd
- moved Achang_Deep to site column and ACH-D to site_code column (they were reversed)

version 2 (2021-01-28): revised some locations, replaces version1 (2016-06-17)

Instruments

Fluorometer

Supplied Name:

Supplied Description:

Diving PAM Underwater Fluorometer (Walz), an instrument for studying in situ photosynthesis of underwater plants.

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.
