Vector averaging current meters have been modified to measure the temperature gradient in addition to
current and absolute temperature. The modified instrument measures the temperature difference between
sensors spaced vertically 1.74 m apart (or closer) using thermistors in a Wheatstone bridge circuit.
Calibrations provide corrections for drift and static offset resulting in temperature gradient measurements
accurate to about 0.5 m ~c;m. Originally developed to infer vertical velocities, the instrument has also
been successfully used to study mixed layer motions and thickness variations and to investigate temperature
fine structure.

Biases in the air-sea flux of CO2 resulting from ocean surface temperature gradients
(American Geophysical Union, 2004-06-30)The difference in the fugacities of CO2 across the diffusive sublayer at the ocean surface is the driving force behind the air-sea flux of CO2. Bulk seawater fugacity is normally measured several meters below the surface, ... -
Momentum, mass, heat, and vorticity balances from oceanic measurements of current and temperature
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1975-07)The local dynamics of low-frequency motions in the MODE region are investigated from three arrays of moored measurements of current and temperature. Tests for lowest-order balances of horizontal momentum, mass, heat, heat ... -
Macromolecular rate theory (MMRT) provides a thermodynamics rationale to underpin the convergent temperature response in plant leaf respiration
(2017-10)Temperature is a crucial factor in determining the rates of ecosystem processes, e.g. leaf respiration (R) − the flux of plant respired CO2 from leaves to the atmosphere. Generally, R increases exponentially with temperature ...
