Among the biologists onboard the NOAA Ship Ronald H. Brown are Dr. Dr. Jonna Engström-Öst and Dr. Olivier Glippa from the Novia University of Applied Sciences in Finland. As we mentioned in another post, one of the zooplankton groups being examined on this cruise is copepods, small crustaceans of the subclass Copepoda. Continue reading “Scoping out Copepods”

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? Continue reading “Pterotomics: The Molecular Machinery of Pteropods”

The Scoop from the Zooplankton Nets

Along with the CTD action you saw in Ring around the Rosette, many of our stations also involve lowering zooplankton nets into the water. Zooplankton are an incredibly diverse group of animals that float freely with the ocean’s currents; they range from tiny, microscopic larvae to giant, 50-ft long jellyfish (this video captures some of their amazing diversity). Continue reading “The Scoop from the Zooplankton Nets”

Daytime Visitors- Dolphins, Whales, and More Critters in Nets

After our previous post, ‘Creatures of the Night,’ we thought we would share with you some of the creatures we found during the day. Given we could see much better, these may be considerably more exciting than the plankton that turned up in our nighttime net tows (although I personally find the bizarre, microscopic world far more interesting). But I will let you be the judge!
