Please join me in congratulating GRG collaborator Dr. Samuel Etienne (Geological Survey of New Caledonia) and team on the publication of our new paper in the journal Marine Geology.

Etienne, S., Le Roy, P., Tournadour, E., Roest, W.R., Jorry, S., Collot, J., Patriat, M., Largeau, M.A., Roger, J., Clerc, C., Dechnick, B., Sanborn, K.L., Lepareur, F., Horowitz, J., Webster, J.M. and Gaillot, A., 2021. Large-scale margin collapses along a partly drowned, isolated carbonate platform (Lansdowne Bank, SW Pacific Ocean). Marine Geology, 436. 10.1016/j.margeo.2021.106477

This paper represents the first contribution from the SEDLAB cruise(s) that were conducted between 7th April to 5th May 2018 onboard the French R/V Alis and acquired geophysical and geological data in the Lansdowne Bank area. GRG team members Dr Kelsey Sanborn and Dr Belinda Dechnik participated in these cruises.

The papers highlights include:

1. The Lansdowne Bank is a partly drowned, isolated carbonate platform of the SW Pacific.
2. Morphologies of the bank top and adjacent slopes have been investigated.
3. Spectacular bank margin collapses and slope failures are described.
4. Margin collapses can affect the entire external reef rim and influence subsequent reef growth.
5. Numerical modeling of the tsunamigenic potential of these slides has been performed.

The data set is really spectacular – check it out!

Cheers

Jody
