Map of Great Barrier Reef study locations with satellite images of Lizard, Low Isles and One Tree Reefs showing survey sites.

Coral reefs need enough living coral cover to support habitats, build carbonate structures and buffer waves, but it has been unclear exactly when reefs shift between healthy and degraded states, especially since different reefs have different baseline coral cover. This study tracked benthic cover from 1995 to 2022 at three Great Barrier Reef sites, indexing … Read more…

Space News: Surprising connections between Earth and Mars

by

Space Connect reported how EarthByters discovered that Earth’s interactions with Mars can drive deep sea circulation here on Earth. The podcast covers how geological records of the deep sea were used to discover a link between the orbits of the two planets and past global warming patterns, talking through the research and their collaboration with Sorbonne … Read more…

Which is true, but as they say, a little goes a long way. In our recent paper in Nature Communications, we studied the history of deep … Read more…
