Biography
As a research marine biologist for the Coastal and Marine Geology Program, I investigate the causes and effects of coral reef degradation. I explore local- to global-scale stressors on reefs, and experimentally determine how environmental variables such as sea-surface temperature, water quality, seawater chemistry, nuisance macroalgae, and ocean acidification affect coral growth, the community structure of reefs, and the process of reef building. My work informs resource managers about the mechanisms causing reef degradation and how management efforts may be improved to protect and restore degraded reefs.

Status: Active Coral Reef Ecosystem Studies (CREST)
The specific objectives of this project are to identify and describe the processes that are important in determining rates of coral-reef construction. How quickly the skeletons of calcifying organisms accumulate to form massive barrier-reef structure is determined by processes of both construction (how fast organisms grow and reproduce) and destruction (how fast reefs break down by mechanical...

Status: Active Measuring Coral Growth to Help Restore Reefs
It is critical to start measuring calcification rates in a systematic way now, particularly at subtropical latitudes where conditions fluctuate seasonally, so that we can understand how dynamic ocean conditions affect calcifying organisms today and predict possible changes in the future. We established a calcification monitoring network in the Florida Keys and have been measuring calcification...

Status: Active Local-scale ecosystem resilience amid global-scale ocean change: the coral reef example
Coral reefs are massive, wave resistant structures found throughout the tropics, where they have long attracted attention for their beauty, ecological importance, and rich biological diversity. However, in recent years attention to these systems has focused on their downturn in health and the potential that they effectively could disappear within a century. Yet while many coral reefs have...

Quantifying uncertainty in Sr/Ca-based estimates of SST from the coral Orbicella faveolata
The strontium to calcium ratio (Sr/Ca) in aragonitic skeletons of massive corals provides a proxy for sea surface temperature (SST) that can be used to reconstruct paleoclimates across decades, centuries, and, potentially, millennia. Determining the reproducibility of Sr/Ca records among contemporaneous coral colonies from the same region is...

A 3,000‐year lag between the geological and ecological shutdown of Florida's coral reefs
The global‐scale degradation of coral reefs has reached a critical threshold wherein further declines threaten both ecological functionality and the persistence of reef structure. Geological records can provide valuable insights into the long‐term controls on reef development that may be key to solving the modern coral‐reef crisis. Our analyses of...

Fidelity of the Sr/Ca proxy in recording ocean temperature in the western Atlantic coral Siderastrea siderea

Here we use samples from a coral-growth study to test the...
