Coastal Observing Research and Development Center

Scripps Institution of Oceanography (SIO) has a few PME T-Chains for coastal monitoring. The T-Chain data is sent via Iridium satellite. SIO and PME engineers programmed Iridium burst data transfer for temperature, pressure, current profiles and GPS location. This allows scientists a real-time look at the water column physical characteristics. These T-Chains are collecting coastal water data off the coast of California.

Kilo Nalu Nearshore Reef Observatory

UH/SOEST researchers at Kilo Nalu Observatory are using PME's T-Chain in their field research at Hawaii. They are interested in shoaling internal tides, which show up as sharp drops in temperature.

Observing Internal Waves

PME's T-Chain is being used to record passing internal waves in the Gulf of Maine. Data was collected off Platts Bank by researchers from the University of Southern Maine. A number of internal waves were collected. They noticed the presence of an internal tide. THe shallower average depth of the pycnocline brings internal waves closer to the surface, with impacts on the euphausiid depths and associate surface flows.

Monitoring Plumes

PME designed a T-Chain with multiple Pressure sensors for the purpose of monitoring internal plumes. The T-Chain was towed by a small boat while measuring temperature at approximately one second intervals with 23 temperature sensors. The T-Chain is expected to drag at an angle in the water column. The three pressure transducers will provide information to help determine this angle. PME also supplied a small GPS receiver and software that runs on the PC.

Looking at Evaporation

A T-Chain is deployed from the side of a floating weather station by researchers from CSIRO, the University of Southern Queensland, the University of Queensland, and Griffith University. They are looking at different ways to estimate evaporation. The long-term goal of the project is to test the effectiveness of evaporation reduction technologies.
