The HyQuest Solutions TB1L tipping bucket flow gauge is used for measuring water seepage coming out of a pipe or a drain. The bucket is connected to its own dual reed switch effectively enabling redundant data acquisition in two distinct data loggers, or providing data to two devices (e.g. a data logger and a counting display), etc.

The TB1L is perfectly suitable for flow measurements in water carrying sediments or iron hydroxide deposition. Made of platsics and coated steel, these devices are both robust and fast and easy to clean.

The bucket tips when it is filled to maximum. The magnet integrated into the bucket rearside slides along the reed switch mounted in the flow gauge’s frame. The magnetic field forces a contact closure in the reed switch. The latter can be recorded by one or two connected data loggers. The number of tips per time unit is a measure of the flow rate.

The Frozen Frontier: Chasing Data in Antarctica

For Paul Savoy, sailing on the Nathaniel B. Palmer research vessel as part of the United States Antarctic Program (USAP) has been a dream come true, a “mountain top” for his career. “I grew up reading about the age of exploration, and the great polar explorers back in the day. Antarctica is one of the last remaining frontiers, along with the deep ocean and outer space. I was delighted to discover Antarctic research covers all three, with deep ocean research happening on the icebreakers and cosmological experiments at the South Pole. I’ve been applying for a job down here since I was 18. I got shortlisted a few times, but never actually got picked up until I was 32. Now I’m 35, and finally headed to the ice.

New Environmental Sensors and Data Acquisition Knowledge Base

NexSens Technology has worked for over two decades to simplify complex environmental data acquisition systems. The core components of these systems have always been the development of data loggers, configuration and data management software, and simplified sensor integrations. NexSens is excited to bring a new dimension to another critical aspect of real-time environmental monitoring: environmental sensors and data acquisition documentation through the revamped online Knowledge Base. The Knowledge Base serves as a living library, featuring the most thorough information, start-up instructions, integration guides, and other documentation available for NexSens systems and products.

The Tiniest Cars: Understanding the Effects of Microplastics on Coral

Like the microplastics she studies, Keiko Wilkins arrived at this point in her life through a long, multi-dimensional, and at times unexpected journey. Today she is a second-year graduate student in the doctoral program at the University of Hawaii , a graduate assistant at Kewalo Marine Laboratory , but her journey began in Pickerington, Ohio, a far cry from the sea. “I always had an interest in water, and I swam competitively,” she recalls. “I knew I wanted to study biology, but did I want to do research or education? So I explored biology further. My academic advisor worked on lakes and I focused on zooplankton in lakes, and changes in their populations. Fascinated by the ocean, I wanted to study it, but in Ohio, the ocean is, of course, out of reach.
