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”

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!
