Wireless Open Water Logger for Ocean Sampling

Creare, LLC helps enable large-scale opportunistic ocean temperature and depth sampling.

The Technology

A new Methane Sensor Package can determine both the concentration and the carbon isotope ratio of methane while operating in situ and at depth.

The technology combines a novel laser absorption spectroscopy gas sensor with a membrane-free approach to water sampling. This approach provides significantly more data at a lower cost compared to the traditional analysis of returned samples.

Traditional measurement approaches involve collecting a limited number of samples, which are initially processed onboard ships, and then later analyzed in a shore-based laboratory through a time-consuming and labor-intensive process.

Opto-Knowledge offers an in situ, real-time methane sensing capability that facilitates:

  1. Finding methane seep and hydrothermal vent sites
  2. Understanding the fate of methane in the water column
  3. Quantifying the extent of microbial activity in vent systems
  4. Tracking methane production and fractionation in real-time

Opto-Knowledge Systems, Inc. was founded in 1991 and specializes in developing turn-key sensors for challenging environments.
