Geology Prof., Alumni Publish Journal Article

Antun Husinec, professor of geology, along with Peter E. Loree ’14 and John T. Murphy Jr. ’11 published an article in the October 2019 issue of Facies, a Springer journal.

The paper, titled “Degrading windward patch reefs and processes influencing composition, mineralogy, and stable‑isotope record of peri‑reefal sediment, San Salvador Island, Bahamas”, focused on the dominant carbonate sediment producers as well as the biological processes that influence production, deposition, and preservation of these reefs and the sediments surrounding them. The study shows that the San Salvador patch reefs have a higher abundance of fleshy seaweeds (algal turfs, upright green algae, brown algae) and lower cover of crustose red algae, which is typical for degrading reefs. Macroalgae have likely reached abundance beyond the grazing capacity of herbivores and consequently have drastically reduced space available for coral settlement and recruitment and compromised reef resilience.

Loree works as a geologist at the Horizon Well Logging/Excellence Logging, an oil and gas company in Tulsa, Oklahoma. Murphy obtained his master’s degree in geology (carbonate sedimentology) at SUNY Binghamton in 2013, and now works for the Central Valley Regional Water Quality Control Board in Rancho Cordova, California.
