Saturday the 17th August saw the research team deploy 5 unsuccessful dredges on the Lexington Seamount – we collected multiple sediment samples (full of foraminifera), several samples of live and deceased deep sea coral but no rocks.

Finally, on the morning of Sunday 18th August – success! Four black rock samples collected in the morning dredge. The morning shift were excited to be back studying rocks, rather than sifting kilograms of sediment.
