GPUs Help Find a Massive New Reef Hiding Behind Great Barrier Reef

Australian scientists made a significant discovery hiding behind the world-famous Great Barrier Reef. The discovery was made using cutting-edge surveying technology, which revealed vast fields of doughnut-shaped mounds measuring up to 300 meters across and up to 10 meters deep.

“We’ve known about these geological structures in the northern Great Barrier Reef since the 1970s and 80s, but never before has the true nature of their shape, size and vast scale been revealed,” said Dr Robin Beauman of James Cook University, who helped lead the research.

The scientists from James Cook University, Queensland University of Technology, and University of Sydney used LiDAR data collected from the Australian Navy to help reveal this deeper, subtler reef. They then used CUDA and GeForce GTX 1080 GPUs to compile and visualize the huge 3D bathymetry datasets.

“Having a high-performance GPU has been critical to this ocean mapping research,” says Beauman.

The discovery has opened up many other new avenues of research.

“For instance, what do the 10-20 meter thick sediments of the bioherms tell us about past climate and environmental change on the Great Barrier Reef over this 10,000 year time-scale? And, what is the finer-scale pattern of modern marine life found within and around the bioherms now that we understand their true shape?”

Next up, the researchers plan to employ autonomous underwater vehicle technologies to unravel the physical, chemical and biological processes of the structures.

GPUs Help Measure Rising Sea Levels in Real-Time

Sea levels have traditionally been measured by marks on land – but the problem with this approach is that parts of the earth’s crust move too.

A group of researchers from Chalmers University of Technology in Sweden are using GPS receivers along the coastline in combination with reflections of GPS signals that bounce off the water’s surface. NVIDIA GPUs then crunch those data signals to compute the water level in real-time.

The researchers are using the cuFFT library, alongside NVIDIA Tesla and GeForce GPUs to process the nearly 800 megabits per second of data that come from the reflectometry stream systems.

Schematics of the data flow for a software-defined radio GNSS-R solution. Direct (RHCP) and reflected (LHCP) signals are received, A/D converted and sent to a host PC, where a Tesla K40 GPU handles signal processing.

“Without the use of GPUs, we would not have been able to process all our signals in real-time,” said Thomas Hobiger, a researcher on the project.

This work has placed the team among the top five finalists for NVIDIA’s 2016 Global Impact Award which awards a $150,000 grant to researchers doing groundbreaking work that addresses social, humanitarian and environmental problems.
