Ocean Science

Ocean Science is the study of the physical, chemical, and biological properties of the ocean. The ocean and its organisms play a critical role in elemental cycling processes—such as those of carbon (C) and oxygen (O)—acting as both a sink and source for greenhouse gases. Examining distribution and trends of these gases, as well as using proxy methods (e.g. isotopic signatures), can illuminate past and present climate and guide understanding of oceanic and atmospheric processes. Sampling methods include ship or air-based methods, SCUBA diving, remotely or autonomously operated underwater vehicles, and satellite observations.

G2131-i Isotope and Gas Concentration Analyzer

The Picarro G2131-i isotope and gas concentration analyer precisely, simultaneously, and continuously measures δ13C in carbon dioxide (CO2) and CO2 and CH4 gas concentration for a range of applications from atmospheric and ocean science research to food and beverage origin and authenticity.


L2130-i Isotope and Gas Concentration Analyzer

High-precision triple oxygen isotope research in water is finally simple and affordable.


L2140-i Isotope and Gas Concentration Analyzer

The Picarro L2140-i isotopic water analyzer enables simultaneous measurements of δ18O, δ17O, δD and determines 17O-excess for paleoclimate, (eco) hydrology, and atmospheric science applications.

AutoMate Prep Device

When a Picarro δ13C-CO2 analyzer is coupled with an Automate FX sample preparation device, the system provides δ13C measurements of the dissolved inorganic carbon in water samples or δ13C in solid carbonate samples. The AutoMate Prep Device adds phosphoric acid to the samples to liberate CO2, which flows to the Picarro for δ13C-CO2 analysis.

Continuous Water Sampler (CWS) A0217

The Picarro Continuous Water Sampler (CWS) incorporates a porous membrane that enables diffusive sampling of water isotopes.


High-Precision Autosampler and Vaporizer

The Picarro Autosampler (A0340) and Vaporizer (A0211) offer exceptional precision with minimal maintenance for ocean science, hydrology, and paleoclimatology applications.
