Hot off the Press! What really controls the shape of beaches in estuaries and bays?

Gazi, M. Y., da Silva, A. P., Villacieros-Robineau, N., Fellowes, T. E., Salles, T., Alejo Flores, I., González-Villanueva, R., & Vila-Concejo, A. (2026). Spatial variability of wave signatures and profile morphotypes of beaches in estuaries and bays across different tidal regimes. Geomorphology. The second chapter of my PhD thesis has now been published! Beaches in Estuaries and Bays (BEBs) are often assumed to be low-energy environments shaped mostly by local winds because they are “sheltered” from the open ocean....

Hot off the press! Spurs and Grooves on forereefs can act as channels to bring sediment onto reef flats

On the last week of 2025- when I was already away on holiday, we had a paper published in the new journal Coastal Futures from Cambridge University Press & Assessment. The paper, a rapid communication on the effects of hashtag Alfred on One Tree Reef, shows for the first time that Spurs and Grooves on forereefs can act as channels to bring sediment onto reef flats....

Having fun hosting a high school group from Yashiro High School from Japan.

Super excited to be up at UQ and QUT working with colleagues on a range of projects Including the HALO project. Here we are sampling some of the giant piston cores we collected from the continental slope and Canyon systems bordering the Great Barrier Reef in 2022.
