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.

Dimethyl Sulfide: A Key to Marine Sulfur Biogeochemistry

Christopher Spiese is assistant dean at the Getty College of Arts & Sciences, acting director of the school of social sciences and human interaction, and associate professor of chemistry at Ohio Northern University. He is also a marine sulfur enthusiast. Marine sulfur biogeochemistry, which involves the cycling of sulfur through aquatic biological and geological systems, is essential for the functioning of marine life. However, the exact chemistry involved is not entirely known, piquing the interest of researchers like Spiese. “I went into marine sulfur biogeochemistry during my graduate work. I completed a doctoral environmental chemistry program at SUNY College of Environmental Science and Forestry (SUNY-ESF) under David Kieber.
