    • This email address is being protected from spambots. You need JavaScript enabled to view it.

    Lew Gramer is a physical oceanographer who completed his Ph.D. at the University of Miami's Rosenstiel School in 2013, while researching environmental data streams and knowledge-based ecological forecasts for CHAMP. He is currently a research associate with CHAMP at AOML-OCED in Miami through the University of Miami's Cooperative Institute, and a postdoctoral researcher at Keys Marine Lab through the Florida Institute of Oceanography. His research focuses on the air-sea and dynamical ocean processes that dominate the physical environment of coral reefs and other shallow marine ecosystems, including horizontal convection, upwelling, mixing, and light attenuation. His current projects include tracking turbidity plumes over reefs in Florida and the Pacific from space, characterizing priority sites for reef resilience and restoration in the Caribbean based on oceanography, and quantifying the impact of upwelling on the physical and chemical environment of corals in southeast Florida. These collaborative, multidisciplinary projects incorporate in situ observations of the ocean and atmosphere, computer modeling, and remote sensing using a variety of platforms. Lew also continues to develop new data sources, analyses, and ecological forecasts for the expanding CREWS network in the Caribbean, and for "virtual stations" (reef sites monitored by remote sensing and reanalysis) around the world.

    • Xaymara Serrano is a postdoctoral research associate working in a project which aims to investigate the synergistic effects of nutrient enrichment and elevated sea surface temperatures (SST) on the ecology, genetics and photo-physiology of Caribbean reef corals during early stages of life. The goal of her project is to assess the thermal sensitivity of new coral recruits after exposure to different nutrient levels, and use various molecular and ecological techniques to monitor how coral recruits change the density of their algal symbionts in response to changes in nutrients, and how these changes subsequently affect thermal tolerance. Dr. Serrano earned her Ph.D. from the University of Miami’s Rosenstiel School of Marine and Atmospheric Science in 2013, where she studied connectivity among Caribbean reef corals from deep and shallow environments.

    Mike Shoemaker ("Shoe") is an Electronics Technician who has been with the CHAMP since the very beginning. He set up the first Northgate computer which ran Remote Bulletin Board System (RBBS) software to provide a telephone dial-in service, which gave daily listings of sea temperatures from the SEAKEYS Network of in situ temperature and meteorological sensors. Those data were later delivered to environmental managers, divers, and fishermen by a fax-modem set up by Shoemaker ("CoralFax"). Ultimately those data came to be displayed on the CHAMP web site. Shoemaker also facilitated the construction of the early Coral Reef Early Warning System (CREWS) stations, which were pylons at Lee Stocking Island, St. Croix, La Parguera and Saipan, and continues to be engaged in all sensor and electronic installation issues for CREWS stations as the network expands throughout the Caribbean. Shoemaker also helps with procurement and computer security issues for CHAMP and its parent organization, the Ocean Chemistry and Ecosystems Division (OCED) of AOML.
