Coast to Coral: Rubble Stabilisation & Dynamics

Join Reef Check Australia and friends on the first Tuesday night of each month in your lounge room/office/comfy chair, for an evening of discovery, inspiration and appreciation of our local marine, coastal and catchment environments.


Tania completed her PhD on rubble dynamics in the Maldives, before starting a postdoc at the University of Qld within the Marine Spatial Ecology Lab. The postdoc is funded by the Reef Restoration & Adaptation Program. Tania is enthusiastic about conservation, advocacy and seeing wild places (Straddie is a fave!) She volunteered as a Reef Check Ambassador for many years, & is also a Reef Check Surveyor, although with all the diving for the PhD & postdoc, she hasn't had much time to participate in surveys! 


Just as buildings can be smashed to piles of rubble during earthquakes, coral reefs can be broken up into vast coral rubble beds following events like storms, bleaching, ship groundings and blast fishing. This can be bad! If rubble is rolling around too much, with the waves and currents, new baby corals are killed and reef recovery is limited. But, if rubble is stable for long enough, critters like sponges and coralline algae (the pink cement of the reef!) can grow over it, sticking it together again like a glue. Rubble beds that move around a lot, and don’t have much binding, are likely good candidates for rubble stabilisation interventions, e.g., rock miles, mesh, Reef Stars, which have been trialled in a few places around the world. We are working to identify where these unstable rubble beds are on the GBR, and which rubble beds won’t recover on their own naturally. To do this, we need to know how fast water flow needs to be to move rubble, as well as what critters bind rubble, and how quickly they do so!


Virtual doors (zoom) opens at 6.25pm for a 6:30 pm start.

Bring a mate and share in the discovery!

At Reef Check Australia we’re all about inspiring our mates and we love to read your thoughts! So, share your favourite parts about the night and tag us! Reef Check Australia #coasttocoral

This initiative is hosted by Reef Check Australia, and proudly supported by oh so many groups including the City of Gold Coast, Port of Brisbane Pty Ltd, Sunshine Coast Council's Environment Levy partnerships grant, The Great Barrier Reef Foundation and Townsville City Council.

Future talks take place on the first Tuesday night of each month, with a new, interesting and engaging speaker.
