Spring 1995 CoOP Field Program

Considerable effort has been directed toward development of the MBARI Ocean Observing
System (MOOS), consisting of a variety of sensors and platforms deployed in Monterey Bay,
communication links, and data management facilities.
Sensors include automated, rugged pCO2 measurement apparatus and osmotically pumped
chemical analyzers developed at MBARI.
Platforms include drifters, moorings, ships, and satellites.
Telemetry infrastructure includes microwave and packet radio links to provide ocean
data in near-realtime.
MOOS was recently utilized as part of the CoOP
Coastal Air-Sea Chemical Fluxes Project Spring 1995 Field Program. Objectives of MBARI
- Determine role of biology in exchange of CO2 between ocean and atmosphere in a coastal
- Measure distribution of CO2, nitrate, oxygen, and silicate as well as horizontal
currents, temperature, salinity, chlorophyll, irradiance, and primary production over
various spatial and temporal scales.
The following tables summarize measurements made by us during the CoOP Spring '95 Field
The table below summarizes the measurements made from RV Point Sur:
||temperature, conductivity, pressure, fluorescence, beam-c, irradiance
||114 casts, 24 Hz during cast
||nitrate, nitrite, phosphate, silicate, oxygen, pCO2, total CO2, N2O, chlorophyll,
primary production, particulate absorption, alpha, Pmax, bacteria, pico-,
||location, temperature, conductivity, nitrate, silicate, fluorescence, absorption,
||every 30 seconds
||every 3 minutes
||every 3 minutes
The table below summarizes measurements made by unmanned platforms:
|MBARI Drifter #4
|every 15 minutes
|NO3, backscatter, fluorescence
||every 5 minutes
|MBARI moorings M1 and M2
||location, wind, air temperature, relative humidity, temperature at 11 depths, beam-c,
fluorescence, irradiance/radiance, NO3, pCO2
||every 10 minutes
||sea surface temperature, wind
|AVHRR (NOAA polar-orbiting satellites)
||sea surface temperature, albedo
||3-4 times daily
MBARI provides these data "as is", with no warranty, express or implied, of the data quality or consistency. Data are provided without support and without obligation on the part of the Monterey Bay Aquarium Research Institute to assist in its use, correction, modification, or enhancement.
