The nighttime bongo tows (see The Scoop from the Zooplankton Nets) provide a wealth of organisms for the biologists aboard the NOAA Ship Ronald H. Brown to study.  From krill and crabs to copepods and pteropods, researchers aboard the Brown are interested in one unifying question: How will ocean acidification change the distribution and abundance of these organisms?

Next stop, San Francisco!

The NOAA Ship Ronald H. Brown will be making a mid-cruise pit stop tomorrow in San Francisco! We’ll spend just under 24 hours tied up at Pier 15, right outside the Exploratorium science museum’s Fisher Bay Observatory. Continue reading “Next stop, San Francisco!”

Pteropod Experiments in a Mobile Laboratory

It all starts with the idea, a hypothesis really, that we are interested to know about the system of our investigation. The subjects of our investigation are pelagic calcifiers called pteropods (also sometimes called “sea butterflies”), that are put in an experimental setup in which we control a variety of different physical and chemical conditions.
