This record describes the deep-sea sediment core products by Holder et al. (2020) from two sites in the Sabrina Coast continental slope and rise, the first sedimentary sequences investigated in this r... moreegion of the East Antarctic.
The cores were used to study changes in the oceanic and depositional environment and their interaction with the nearby Totten Glacier. The two archives show clear variations between glacial and interglacial phases over the last 350 Kyrs, driven by the movement of the ice sheet advancing and retreating over the continental shelf and ocean circulation patterns that deliver heat either close to the Antarctic coastline or further away from the continental slope.
This research provided a foundation for future palaeoceanographic work in the region and suggested that warm oceanic conditions, similar to today, have influenced the Sabrina Coast during past warm interglacials over the last 350 Kyrs.

3D laser scan data of Jenolan Caves, NSW, Australia. Data were acquired using three 3D mobile mapping systems developed at CSIRO. The vast majority of the data was collected using the Zebedee 3D Mappi... moreng System, a handheld lidar system that generates maps from measurement collected as an operator holding the device traverses through the site. Other data were acquired from the bentwing 3D Aerial Mapping System, which has similar sensors to Zebedee mounted on a quadrotor MAV platform.
The primary representations provided are detailed 3D point cloud maps of the caves and the surface above them (approximately 2.3 billion points), as well as the trajectory estimate of the laser scanner as it was carried through the environment (approximately 28.4km over 22 hours of data collection).less
