The data types involved are both measured and calculated, and include benthic data from analysis of images captured at the study sites, as well as various environmental data types from both deployed instrumentation and collected seawater samples at the study sites. The data types include: benthic taxa, depth, temperature, salinity, pH, dissolved inorganic carbon, total alkalinity, partial pressure of CO2, aragonite saturation state, oxygen, nitrite, nitrate, phosphate, total ammonia, ammonium, orthosilicic acid, and photosynthetically active radiation. Source imagery is not included as part of this archival package. This dataset is available to the public for a wide variety of uses including scientific research and analysis.

Updates are performed as needed to maintain currentness. NOAA National Centers for Environmental Information custodian camera camera An instrument for recording images. CTD CTD Conductivity-Temperature-Depth probe PAR Sensor PAR Sensor Photosynthetically Active Radiation Sensor The PAR sensor measures global solar radiation from 400 to 700 nm, which approximates the spectral band active in photosynthesis. The response of the instrument falls sharply to zero on either side of this band, and between 400 and 670 nm it increases monotonically from about 50% to 100%. There is no protective glass dome over the receiving surface. Irradiance from the sun passes through a small white visible bandpass filter/diffuser in the shape of a horizontal disk at the top of the instrument. Within the instrument radiation is directed through a series of colored glass filters and onto a silicon photodiode detector. The factory-supplied calibration converts the signal from the detector to a flux of photons in micro-mole (of photons) s-1 m-2. (One micro-mole equals 6.022 E17 photons.) For the solar spectrum, these units may be converted to watts per square meter by dividing by 4.6. (http://www.srrb.noaa.gov/instrument/par.htm) spectrophotometer spectrophotometer 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.
