Overview
The Aanderaa 4296 Turbidity Sensor fits directly on the SeaGuardII top-end plate and is interfaced by means of a reliable CAN bus interface (AiCaP), using XML for plug-and-play capabilities. The sensor can also be used as a stand-alone sensor with RS-232 output. The sensor is available in three different depth ratings: 300-meter, 3000-meter and 6000-meter.
Mechanics
The Aanderaa Turbidity Sensor measures the backscatter of infrared light. A high-efficiency light-emitting diode is used to transmit modulated light into the water. The backscattered light is picked up by a sensitive photodiode, and this signal is then conditioned, linearized and converted to data in the engineering unit (FTU). In addition to turbidity, the sensor also measures water temperature.

SonTek CastAway-CTD Meter Review
Lightweight and easy to use, the SonTek CastAway offers a convenient 3-in-1 solution for measuring conductivity, temperature, and depth profiles. At a 5 Hz sampling rate, the CastAway is designed for up to 1 m/s free-fall through the water column. 
 
 With fast response and accurate conductivity, temperature, and depth measurements, the CastAway is ideal for thermocline and halocline profiling. The unit also reports salinity and speed of sound.

Wesley Turner, an Environmental Scientist Advisor with the GIS and Data Analysis Section of the Watershed Management Branch in the Kentucky Division of Water , spends his days researching current technology and developing various drone programs for the Division of Water. 
 
Having grown up during Love Canal and Valley of the Drums, Turner decided at a young age that he wanted to become a scientist and spend his life trying to right humanity’s wrongs and protect the environment. 
 
“I loved looking at the plants and animals on the farm where I lived. I wondered at the beauty and mystery of the soil and water in the surrounding fields. As I grew older, I learned of the problems our species caused on the planet […] I remember thinking things had to change,” recalls Turner.

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.
