Full description

During voyage 3 of the RSV Nuyina during the 2025/2025 season to the region offshore the Denman glacier, rock samples were recovered to understand i) the continental geology of the Bruce Rise, ii) the onshore geology of the Denman region (from ice-rafted debris samples), and iii) the timing and mechanism driving formation of seamounts (extinct seafloor volcanoes).

The voyage was colloquially known as the "Denman Marine Voyage", as it operated in the vicinity of the Denman Glacier.

Rock samples were recovered from dredge (DXX), beam trawl (BT-Y), kasten core (KCXX), and multicore (MCXX) deployments during the voyage (where XX is the sequential deployment number, and Y is the sequential deployment letter).

Folders in this dataset are named by their deployment type and number/letter. Within each folder there are i) descriptions of each rock/sediment sample, and ii) photographs of each sample. Descriptions are preliminary and were undertaken on board look at the hand samples, and sawn hand samples using a hand lens.

Dredged rocks were described and photographed individually. For the case of sawn rock saws, photographs of the cut surfaces both dry and wet were taken. Beam trawled rocks were sorted into groupings and a description and photographed in these groups. Samples from kasten cores and multicores were described individually. Photographs of the kasten core and multicore rocks sometimes contain multiple different samples per photograph.
