        abstract:  The World-wide Ocean Optics Database (WOOD) was developed to be a comprehensive publicly-available oceanographic bio-optical database providing global coverage. It includes nearly 250 major data sources (including international contributions as well as US sources (e.g., NASA, NODC) of optics and chlorophyll profiles) and holds over 40 derived and measured physical properties of interest to optical oceanography, including Inherent and Apparent Optical Properties (IOPs and AOPs), pigments and nutrients, Secchi depths, along with co-located supporting parameters such as temperature and salinity.
        purpose:  The primary goal of this work has been to establish a unified optics database that collects, in one place and in one format, as many of bio-optical data sets as possible. The data have been converted to a common data format with extensive efforts in editing wild points and the removal of spurious data regions. Optical measurements are recorded at the measured wavelength. One parameter of particular interest is Kd, the diffuse attenuation coefficient which is either computed from downwelling (Ed) light or from an empirical relation with chlorophyll which is good to within 10% in open ocean conditions.

            description:  The Secchi disk (or Secchi disc), as created in 1865 by Angelo Secchi, is a plain white, circular disk 30 cm (12 in) in diameter used to measure water transparency or turbidity in bodies of water. The disc is mounted on a pole or line, and lowered slowly down in the water. The depth at which the disk is no longer visible is taken as a measure of the transparency of the water. This measure is known as the Secchi depth and is related to water turbidity. [Wikipedia, 2021-09-02]

            description:  spectrophotometer, optical spectrometer, spectrograph or spectroscope An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. Butler, L. R. P.; Laqua, K. (1995). "Nomenclature, symbols, units and their usage in spectrochemical analysis-IX. Instrumentation for the spectral dispersion and isolation of optical radiation (IUPAC Recommendations 1995)". Pure Appl. Chem. IUPAC. 67 (10): 1725–1744. doi:10.1351/pac199567101725. A spectrometer is the general term for describing a combination of spectral apparatus with one or more detectors to measure the intensity of one or more spectral bands."
