Description

Physical and optical data from 3 wave-powered profiling moorings (WireWalkers) (.mat files)

Data are collected onboard the profilers. Those data were collected by a CTD with additional channels. The data are provided as vectors (upcast only). The .idx field indicates the start and end of each individual profile. The channels are, as follows:

Upcast only time series:
T = Temperature, degrees C (Seabird 49 CTD or Seabird 52 for ww_esp)
P = Pressure, meters (Seabird 49 CTD or Seabird 52 for ww_esp)
time = Time (matlab datenum format)
C = conductivity (milliSiemens per meter) (Seabird 49 CTD or Seabird 52 for ww_esp)
S = salinity (PSU) (Seabird 49 CTD or Seabird 52 for ww_esp)
F_chla = Chlorophyll fluorescence (Relative Fluorescence Units) (Turner Designs Cyclops 7 chlorophyll fluorometer)

or for ww_esp:
C3_chla: Chlorophyll fluorescence (Relative Fluorescence Units) (Turner Designs C3 fluorometer)
C3_cdom: Chromophoric Dissolved Organic Material (Relative Fluorescence Units) (Turner Designs C3 fluorometer)
C3_turb: Turbidity (Relative Fluorescence Units) (Turner Designs C3 fluorometer)

Methods & Sampling

Dataset acquisition description

Sampling and Analytical Methodology:
These data come from a set of wave-powered profiling moorings. > 8,000 profiles were collected at each mooring. The downcast have been excised due to low data quality. The CTDs were recently calibrated, while the fluorometers are reported as RFU (rather than chlorophyll concentrations) given uncertainties associated with non-photochemical quenching.

ww_m19 and ww_wqm2 CTDs sampled at 16 Hz, while ww_esp CTD sampled at 1Hz. ww_esp also had compromised salinity for much of the deployment due to fouling in the conductivity cell.

The moorings were at the following depths: ww_m19 = 50m, ww_wqm2 = 22m, ww_esp = 22m.

Data Processing Description

Dataset Processing Description

Data Processing:
The data have been processed by removing the downcast (e.g. resulting data is only from profiler upcasts). Individual upcasts are indexed in the .idx field. Otherwise the data are unprocessed.

Generic Name: CTD Sea-Bird

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/130/

Generic Description:

Conductivity, Temperature, Depth (CTD) sensor package from SeaBird Electronics, no specific unit identified. This instrument designation is used when specific make and model are not known. See also other SeaBird instruments listed under CTD. More information from Sea-Bird Electronics.

Fluorometer

Supplied Name: Turner Designs Cyclops 7 chlorophyll fluorometer

Supplied Description:

Turner Designs Cyclops 7 chlorophyll fluorometer

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.
