The sample is made alkaline (pH 12-13) with potassium hydroxide to precipitate magnesium as magnesium hydroxide. CalVer 2 Indicator is added and combines with any calcium to form a pink-red color. As EDTA is added, it reacts with the free calcium ions present. When no free calcium ions remain, the EDTA then removes the calcium complexed with the indicator, causing a color change to blue.
  • Range: 10-160 mg/L as CaCO3
  • (100) CalVer 2 indicator powder pillows
  • (1) 100 mL potassium hydroxide standard solution, 8.00 N
  • (1) EDTA titration cartridge, 0.0800 M

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.

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.
