Awards Ceremony Speech Citation for presentation of the 2004 F.W. Clarke award to Andrea Grottoli It is with great pleasure that I introduce Andrea Grottoli as the 2004 winner of the F.W. Clarke award. Andrea is extremely well qualified for this award in all respects and deserves the recognition that this award brings. The work that Andrea carried out and which forms the basis of this award involves the experimental growth of zooxanthellate corals under controlled conditions (involving the manipulation of light and feeding) and the subsequent examination of changes in the stable carbon isotopic composition of the skeletons. This work was published in three fundamental papers (Grottoli and Wellington, 1999; Grottoli, 1999; Grottoli, 2002), the first of which, in the journal Coral Reefs, was awarded the best paper of the year in 2000. The journal Coral Reefs is the premier journal in the field of reef studies and has one of the highest impact factors in the biological sciences. Her work strongly supported the previous assumptions regarding the fractionation of carbon isotopes in coral skeletons that insolation is the primary controlling factor on the stable carbon isotopic variations in coral skeletons. However, not all her results are straightforward and corals are still proving to be unpredictable. I guess this is a good thing as it means we will be seeing more from her in the future on this topic. As pointed out to me recently by an editor of Geochimica Cosmochimica Acta, work involving corals is extremely difficult, as these animals are notoriously problematic to grow and require an extraordinary amount of work. This makes her work all the more valuable as there have been only a handful of such experimental studies carried out since the start of stable isotope geochemical studies on corals in the 1960s. Andrea finished her first degree at McGill University and completed her Ph.D. under the guidance of Jerry Wellington at the University of Houston. It was during this time when I first met Andrea, when she ran samples for her Ph.D. work in my laboratory 1997. The laboratory at Rice University, where she previously had been carrying out her work, closed, and she needed somewhere to finish her analyses for her thesis. I was immediately impressed

with the experimental design of her project, her knowledge of the field, and her dedication to getting the job done. After her Ph.D, she completed a Postdoctoral fellowship with Ellen Druffel at the University of California at Irvine. Here, she investigated 14C in corals. In her present position at the University of Pennsylvania she is continuing her groundbreaking work in the field of carbon isotopic fractionation in corals and has also added the study of sclerosponges to her arsenal. Andrea has already garnered attention from the international community, winning an award from the American Society of Mass Spectrometry and being selected as Associate Editor for the journal Coral Reefs. In this latter capacity I successfully collaborated with her to edit a special issue of the journal on the use of proxy indicators in coral reefs, which recently appeared. In summary, Andrea Grottoli is an accomplished young scientist with a promising future. She has demonstrated excellence in her chosen field and has diversified into new related fields. Ladies and Gentleman, once again I present Andrea Grottoli. Associate editor: Frank Podosek
