Overview
Built to withstand extended periods of immersion, the compact HOBO Water Temp Pro v2 Logger provides reliable, accurate underwater temperature measurements. The small size of the logger allows it to be easily mounted and/or hidden in the field.
Durable
The HOBO Water Temp Pro v2 logger is waterproof up to 120 m (400 feet) and rugged enough to withstand years of use, even in stream conditions. It has enough memory to record over 42,000 12-bit temperature measurements.
Mechanics
The Water Temp Pro v2 Logger requires an infrared base station (90706) or shuttle (90707) and HOBOware, available as a free download, or HOBOware Pro software (sold separately) for system launch and data retrieval. The associated couplers are included with both the base station and shuttle. In addition, the shuttle can operate as a base station for added flexibility in the field.
Data Storage
The high-speed infrared communications offloads data in less than 30 seconds (requires USB port), and the infrared communications port is located opposite the bail end for convenient access while tethered. Offload data or check the logger and battery status, even while logging. A blinking LED indicates that the logger is recording data. To reduce visibility in the field, this feature can be turned off. Non-volatile EEPROM memory retains measurements in the event of battery failure.

Going, Going, Gone: Endangered Species Recovery and Conservation
Across the planet, biodiversity and natural habitats are declining dramatically. Countless species of flora and fauna around the world are being listed as either threatened, endangered, or extinct. According to a 2019 UN Study , around one million species are already at risk of extinction. Unless action is taken to reduce the causes of biodiversity loss, many of these species could disappear within the next few decades. Invasive species, habitat destruction, pollution, and other environmental stressors are all major causes of biodiversity decline. While high biodiversity is synonymous with places like the Amazon Rainforest and the Great Barrier Reef, it can also be found locally.

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.
