Lake Diagnostic System (LDS)
Water quality monitoring of water column temperature stratification, meteorological parameters (wind and solar energy) and water quality parameters (oxygen and conductivity) with real-time data.

T-Chain
Produces detailed data that can be used to determine water column temperature stratification, oxygen concentration and depth.

Self Contained Autonomous MicroProfiler (SCAMP)
A free-falling instrument that records microstructure measurements of conductivity, temperature, temperature gradient, chl-A fluorometry, and PAR in lakes, estuaries, and the ocean.

MicroScale Conductivity and Temperature Instrument (MSCTI)
Measures high-resolution conductivity and temperature of water in the laboratory.

Array for Real-time Geostrophic Oceanography (ARGO) Antenna
The ARGOS antenna is a coaxial dipole construction, and is intended for use with oceanographic instruments that transmit data through ARGOS satellite.

T-Chain Collects Data on Thermal Plumes
July 21, 2008
The T-Chain could be towed behind a boat and, if coupled with concurrent GPS position measurement, could acquire a {x,y,z temperature} measurement set. This data set could be used to determine the position of thermal plumes from coastal power plants.


T-Chain Collecting Data for over Four Years
May 7, 2008
A T-Chain installed in Silvan Reservoir, Australia, has been collecting continuous temperature data without any interruptions for over four years. Deployment was November, 2003.

Looking back at 2007
January 29, 2008
2007 was a great year for PME. All product sales increased, and a few large projects came our way. We are excited for 2008.
Clelia from CWR Visits PME
December 10, 2007
PME was delighted to have Clelia Luisa Marti, Field Operations Manager at the Centre for Water Research, visit us. The future progression of the LDS was discussed.
New T-Chain Re-Calibrating System
November 12, 2007

PME is in the process of designing a re-calibration system for the T-Chain. The T-Chain will need to be re-calibrated every year or two to maintain accuracy.

ARGO Float Number 3,000 Dropped
September 10, 2007
Argo, an international research program, has over 3,000 floats around the world collecting data on temperature, salinity, and velocity of the upper ocean. PME creates the antenna used to transmit this data.
