The 2010 edition of the annual Woods Hole Oceanographic Institution [1] (WHOI) calendar has recently been released and features several full color images of zooplankton taken by Census scientists. For thirty years WHOI biologists Larry Madin and Richard Harbison – with associates Ron Gilmer and Erich Horgan—have been leaders in studying these fragile animals, focusing on their ecology, behavior, and roles in the ocean. Single copies of the calendar can be ordered online through the WHOI shop [2]. Bulk orders of 5 or more may be arranged by contacting the shop directly [3].
