SUAVE
SUAVE, or a System Used to Assess Vented Emissions, provides continuous, in-situ analysis of hydrothermal chemical species such as iron, manganese and hydrogen sulfide based on principals of flow analysis and colorimetric detection. In addition to chemical components, SUAVE is equipped to accept signals from an array of auxiliary sensors that include state of the art CTD sensors, optical sensors, thermisters, or any other sensor with output between 0 and 5 vdc. SUAVE is extremely versatile and can be mounted on a wide variety of platforms for sampling during profiles or transects, or deployed for short term monitoring applications.

NeMO Net RAS
The RAS (Remote Access Sampler) is capable of collecting 48 vent fluid and particle samples in a time-series. The system is a McLane 48-500 Remote Access Sampler, with hardware and software enhancements done at PMEL. Temperature measurements are made every 10 minutes. The sampler is programmed to take a water/particle sample once per week and collect chemical sensor data (pH and H2S) twice per week. The system can also be sent a command at any time via satellite to collect samples or send back temperature data. This interactivity will allow us to take samples quickly and at critical times, for example in response to any seismic or volcanic activity, long before any ship could get to the site. By having these instruments in place we hope to learn more about the dynamic early stages of such events.

MAPR
The PMEL MAPR was designed to be a relatively inexpensive, lightweight yet rugged, simple to use self-contained instrument for recording temperature, pressure, optical, and conductivity data on a wide variety of deployments.
