It's often said that we have better maps of the moon's surface than we do of the ocean floor. But the VENUS Seafloor Observatory in British Columbia’s Salish Sea, which celebrates its 10th anniversary on Feb. 8, is trying to change that.

Short for Victoria Experimental Network Under the Sea, VENUS collects oceanographic data on physical, chemical, biological and sediment conditions in Saanich Inlet and in the Strait of Georgia. Run by the University of Victoria’s Ocean Networks Canada, VENUS was the world’s first interactive realtime portal into the ocean. It has 40 kilometres of cables and dozens of sensors that continuously transmit ocean data including temperature, salinity, pH, tides, seismic activity and noise levels to the surface for scientific study.

In honour of VENUS’s milestone, here are ten cool images and videos it has captured in its decade of operation.

1. Octopus on the hunt

8. Impressive tentacles
A large octopus attempts to capture a prawn drawn to pick at the bones of the skeleton of a pig in a cage, part of forensic research project.

9. Shark attack?
