CastAway Doubts about Conductivity, Depth and Temperature Monitoring

The Sontek CastAway-CTD is a castable device that measures conductivity, temperature and depth. The instrument has been used in the field for over a decade by oceanographers, limnologists, divers, fishers and educators. There have been few changes since the first iteration in 2010, showing that the instrument is durable and accurate without requiring new models.   The CastAway is the first conductivity, temperature and depth (CTD) instrument of its kind. While other CTDs are large and cumbersome to deploy, with cages and isolated sensors, the CastAway is a small, lightweight and easy-to-use instrument. Typical CTDs utilize pumps to ensure water flows over the sensors during deployment.

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.

Green Water in Green Bay: Using Data Buoys to Monitor the Southern Bay

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.
