Overview
The Solinst Readout Unit (SRU) is an in-field device designed to take and display instant water level readings from a deployed Solinst datalogger. When connected, users can select a real-time sampling rate and start a real-time monitoring session independent of the datalogger’s internal logging mode.
Real-Time Data
Real-time logs can be saved in the SRU memory. The SRU has an internal barometer, which provides the option of showing and saving real-time water level readings corrected to ambient air pressure. The SRU also functions as a data download and storage device with a robust flash memory. Saved files can be trasnferred to a PC. The SRU allows users to access information about the connected datalogger’s status, including battery level, memory, serial number, firmware version, and logging mode, as well as the SRU status.
Connections
The SRU connects to a Levelogger’s Direct Read Cable, a LevelVent Wellhead, or AquaVent Wellhead connector cable. The LCD screen contrast is adjustable to ensure easy viewing in any field condition. To transfer data files to a PC, the SRU connects using a USB cable. Levelogger Software is used to download, view, export, delete data and set up dataloggers. Through the Software, the SRU has upgradable firmware, which allows for future improvements and compatibility with new dataloggers.

Cal Poly, San Luis Obispo Manages Monitoring Efforts in Morro Bay
California Polytechnic State University, San Luis Obispo (Cal Poly, SLO), has been monitoring Morro Bay for decades, and while the monitoring program has changed over the years, the dedication to monitoring the bay has remained the same. 
 
The project started in 2006 as a Packard Foundation-funded initiative to monitor water quality flowing in and out of Morro Bay. The goal at the time was to use the data collected to develop and inform an ecosystem-based management plan in collaboration with the Morro Bay National Estuary Program (MBNEP). 
 
Since the estuary was the focus at the time, researchers were monitoring water flowing into the estuary from Chorro Creek and Los Osos Creek.

While the bay of Green Bay has been referred to as the largest freshwater “estuary” in the world, the watershed hosts intensive agriculture and contributes one-third of Lake Michigan’s total phosphorus load. 
 
 The Fox River flows into the bay, carrying excess nutrients largely the result of non-point source runoff from the watershed. With a history of deterioration extending well into the last century, the bay ecosystem suffered significant declines in water quality. 
 
 This, in turn, stimulated major clean-up and ongoing restoration efforts to improve water quality. Tracking these changes is an important aspect of ecosystem management.
Read MoreCross-Border Sewage Contaminated Flows: Monitoring the Tijuana River
The Tijuana River runs across the US-Mexico boundary, flowing into and throughout southern California, carrying with it nutrients and contaminants throughout the estuary. In recent decades, the flows have been heavily polluted with untreated sewage from the City of Tijuana. 
 
The wastewater enters the greater Tijuana River estuary, impacting coastal communities and disrupting the natural environment. In order to better understand these cross-border flows, researchers out of San Diego University sought to monitor the waterway test the capabilities of in-situ sensors to measure the contaminated water. 
 
Natalie Mladenov and Trent Biggs were two of the researchers involved in the project, deploying a real-time monitoring system in May of 2021.
