Questions & Answers
How often should I change the RDO cap?

The RDO cap needs to be changed once a year. The RDO sensor has an internal clock that counts down the 365 day lifespan of the RDO cap. The countdown begins the day the cap is installed, sensor is connected to the meter, and the first measurement is taken. The meter will display an "Err 181" message when the cap needs to be replaced.

My sensor is reading a bad zero point calibration.

The sensor must be in an oxygen-free solution for at least 5 minutes.

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.
