Quantitative evaluation of the roles of ocean chemistry and climate on ooid size across the Phanerozoic: Global versus local controls
Ooid size in natural systems can be predicted based on the expected equilibrium between
precipitation and abrasion rates. Therefore, ooid size distributions may enable quantitative …

Regional shifts in paleohurricane activity over the last 1500 years derived from blue hole sediments offshore of Middle Caicos Island
Coastal communities are vulnerable to sea-level rise and hurricane-induced flooding. Our
ability to assess flooding risk at coastal locations is restricted by the short observational …
