Land/Ocean Biogeochemical Observatory in Elkhorn
Sensors and Moorings
instrumentation in the LOBO project is a combination of commercially
available and 'in house' technology. Combined with a mooring system
that allows for long term deployment and rapid data transmission through
a wireless LAN, the sensors can return near-real time information for
extended deployment periods.
More information on the MBARI chemical sensor program is available here.
Instruments deployed in the LOBO sensor array:
- in situ ultraviolet spectrophotometer
- measures the naturally occurring absorbance of UV light by
the nitrate molecule
YSI 9600 Nitrate Monitor
- in situ nitrate sensor
- uses a colorimetric wet chemical technique to measure nitrate
and nitrite in a water sample, analogous to the wet chemical
techniques employed by a typical autoanalyzer
- Oxygen sensor from Aanderaa
- Principle of measurement based on the effect of dynamic luminescence
quenching by molecular oxygen
- Conductivity (i.e. salinity), temperature, and depth.
- We employ CTD's from Sea-Bird Electronics (SBE-16plus and
SBE-37) and YSI environmental (6600).
- Simultaneously determines both chlorophyll fluorescence and turbidity
- Acoustic Doppler Current Profiler from RD Instruments.
- Using sound waves, the ADCP can determine the current flow
throughout the water column.
