OOI RSN Principal Engineer Mike Harrington takes a look at the element management system (EMS) that monitors junction-box power and communications. The EMS provides current, voltage, and temperature information from the node in real time and is vital to monitoring the health and safety of the instruments. Alarms are generated when a parameter moves out of range so that corrective actions may be taken. --Photo by Mitchell Elend, UW

Overview of the system under test. On the bench is the open-frame prototypte of the low-power junction box. To the right is an osciloscope for signal monitoring. The junction box is connected to the three first-article instruments submerged in freshwater in the tank beneath the bench. ---Photo by Mitchell Elend, UW

The coastal oceans and associated ecosystems off of the Pacific Northwest are strongly impacted by wind-driven upwelling in the spring and summer of deep, nutrient-rich water. Satellite images highlight blooms of chlorophyll associated with these events that typically last 2-20 days.

Clams are commonly found at the summit of Southern Hydrate Ridge surrounding areas of white bacterial mat.

Einstein's Grotto, at the summit of Southern Hydrate Ridge, is a main target site for installation of cabled chemical and biological sensors in 2014. The area hosts extensive white bacterial mats and was a site of vigorous venting of large methane bubbles.

A variety of sensors will be deployed on the RSN cabled network in 2013 to investigate the dynamic environment of methane seeps, gas hydrate formation, and associated biological communities. The instruments include seismometers to detect earthquake, fluid flow sensors, digitial still cameras, and a mass spectrometer for quanitfication of gas compositions.

To measure vent fluid salinity at Axial, a temperature-resistivity (chlorinity) probe will be deployed in the International District in 2013. The one shown in this image, was deployed in a 380°C vent in the Main Endeavour hydrothermal field north of Axial.
