Methods for measuring and monitoring ocean processes have changed dramatically over the past few decades.

Within the span of a single oceanographic career, methods have evolved from the necessity of water sample collection with laboratory analysis for even the simplest measurements to using autonomous instruments to collect real-time data on moorings, gliders, profilers and other instrumented vehicles. These alternative platforms require accurate, stable and low powered instruments that are capable of long-term deployment. Satisfying these measurement needs is what drives research and development at Pro-Oceanus.

Very early at Pro-Oceanus we recognized the possibility of developing exceptionally stable and highly accurate and precise submersible sensors for measuring dissolved gas pressure. From this early vision we developed our first in situ instrument, the GTD-Pro™. The Pro-Oceanus GTD-Pro™ has now been used by researchers around the world to study gas exchange, ocean mixing, saturation in rift lakes, net primary production, denitrification, and carbon export. The same technological advances that led to the GTD-Pro™, subsequently allowed us to develop our industry-leading in situ dissolved CO2 sensor, the CO2-Pro™.

Many of our customers face unique challenges in their research and this leads to active involvement of PSI scientists and engineers. The combined knowledge and experience of the PSI team allows us to face these challenges and respond with highly innovative and practical solutions.

PSI continues to invest heavily in research and development in an effort to provide the most useful and reliable dissolved gas sensors in the marketplace.

Engineers and scientists at PSI are currently involved in:

  • Improving all aspects of our current instrument designs
  • Developing gas sensors for measuring a broader range of dissolved gases
  • Improving anti-fouling techniques
  • Designing more versatile controllers and data loggers
  • Developing a compact, reliable sensor for measuring DIC
