Overview
The Hach sensION+ 5059 Portable Multi-parameter Electrode measures pH, conductivity and temperature. It has a plastic body, non-refillable gel reference electrolyte and built-in temperature sensor. The standard-sized electrode has a fixed 1-meter cable and MP8 connector dedicated for use with Hach sensION+ MM150 portable meters. The Hach sensION+ 5059 Portable Multi-parameter Electrode has a ceramic pin reference junction and glass (pH), titanium (conductivity), and Pt1000 (temperature) sensors. It is ideal for measurements in general aqueous applications.
Design
The Hach sensION+ 5059 Portable Multi-parameter Electrode's non-refillable gel reference electrolyte and ceramic pin junction with an integrated Pt1000 temperature sensor provides accurate, stable results without concerns for repeated maintenance. Its resilient polycarbonate body, handle, and MP8 connecter ensure protected performance in the field. Its heavy-duty electrode handle design is optimized for field calibration and storage, as the tubes screw directly onto the electrode handle. This design provides a secure interface between the electrode and calibration/storage tube, reducing the risk of contamination.

Ocean acidification: University of Washington's giant plastic bags help control research conditions
With oceans becoming more acidic worldwide, scientists are getting creative in designing experiments to study them. For example, one group at the University of Washington is using giant plastic bags to study ocean acidification. 
 Each bag holds about 3,000 liters of seawater and sits in a cylinder-like cage for stability. The group at UW, made up of professors and students, is controlling carbon dioxide levels in the bags over a nearly three-week period, during which they are looking at the effects of increased acidity on organisms living near the San Juan Islands. 
 “These mesocosms are a way to do a traditional experiment you might do in a lab or classroom,” said Jim Murray, professor of oceanography at the University of Washington.

National Oceanic and Atmospheric Administration scientists detected signs of ocean acidification in the waters that hold the vulnerable and valuable fisheries of the North Pacific off the coast of Alaska, but they only had a snapshot of the action. 
 
“We know that in this place were important commercial and subsistence fisheries that could be at risk from ocean acidification,” said Jeremy Mathis, a NOAA Pacific Marine Environmental Laboratory researcher and professor at the University of Alaska Fairbanks. 
 
To understand how ocean acidification affects the North Pacific, NOAA scientists created a mooring network that collects constant in situ data on parameters contributing to acidification. They hope it will reveal seasonal trends and patterns left out by their snapshots.

Citizen science programs have popped up across the United States, focusing on connecting local communities with nearby water resources and building a trustworthy data pool over the sampling period. While commonly utilized as a means of ensuring that large watersheds or lake regions are adequately sampled, the credibility and success of such programs have been called into question. 
 
[caption id="attachment_38996" align="alignnone" width="940"] HRWC volunteers measure stream velocity across a subsection of Woods Creek, a tributary of the Huron River near Belleville, Michigan. Stream velocity measurements can be combined with water level measurements to calculate stream flow and chemical parameter loads.
