The purpose of this seminar is to explore the effects of pollution and environmental regulation on water and related environmental resources. Proceedings of the seminar, collections of the lectures, are published yearly. To date, forty volumes have been published. Besides these volumes, the seminar has contributed over forty articles written in seven languages abroad and in the United States. The research institute of the seminar, the American Academy of Ocean Sciences, conducted research actively from 1969 to 1985. During the past thirty years, thirty-three graduate students have participated in the seminar and their participation has been credited toward their studies.

CRUSTACEANS IN A CHANGING OCEAN: ASSESSING THE EFFECTS OF ENVIRONMENT ON ADHESION AND BIOMINERALIZATION
Gary Dickinson, College of New Jersey
Abstract

Abstract

Ocean acidification (OA) adversely affects a range of marine calcifying organisms such as mollusks and corals, causing growth reduction, dissolution of mineralized structures, and compromised mechanical integrity of shells. Crustaceans, however, exhibit mixed responses to OA, and the current paradigm is that they are less susceptible to it than are other invertebrate taxa. We question this paradigm in three ecologically and economically important crustaceans, two Alaska king crabs species and a semitropical intertidal barnacle. In these, we found that OA compromised shell mechanical properties, which may alter their survival and thereby affect ecosystem dynamics.
