System Specifications

WATER QUATLITY MEASUREMENTS

Water Temperature
Water temperature at the depth of the sensor. (units = °C)

Salinity
A measurement of salt content of the water at the depth of the sensor. (units = Practical Salinity Scale 1978)

Sensor Depth
Distance sensors are below the water's surface. For sensors in a fixed position attached to a pier, depth measures the tidal range. (units = meters)

Chlorophyll
Phytoplankton pigment concentration estimated from fluorescence measurements. (units = µg/L)

Turbidity
Turbidity is a measure of relative clarity of the water. (units = nephelometric turbidity units, NTU)

p(CO2)
Partial pressure of carbon dioxide in water. (units = microatmospheres, µatm)

METEORLOGICAL MEASUREMENTS

Air Temperature
Air temperature, typically measured 2 m above the ground. (units = °C)

Wind Speed
Velocity of wind measured 10 meters above the ground. (units = m/s & mph)

Wind Direction
Direction from which the wind is blowing, measured 10 meters above the ground. (units = ° & compass)

Relative Humidity
Amount of atmospheric moisture present relative to the total amount of moisture that the air can hold. (units = % of saturation)

Rainfall
units = mm of water

Photosynthetically Available Radiation (PAR)
Measurement of light available to plants for photosynthesis [wavelengths 400-700 nm]. (units = µmol quanta m^-2 s^-1)

SCOOP is operated by the University of California Santa Cruz, with initial support from the California Program for Regional Enhanced Monitoring for Phycotoxins (Cal-PReEMPT), and the City of Santa Cruz.

Member of CeNCOOS - Central and Northern California Ocean Observing System, and HABMAP - Harmful Algal Bloom Monitoring and Alert Program
