Remote Underwater Exploration
Interesting news and activities
With all the rain and high winds we have been getting lately (not to mention the Sydney COVID lock-down), it has been very hard to get out and under the water to do any exploring lately. Visibility has been terrible and the swells… just aren’t swell.
Dave did get out yesterday for a quick look around Batemans Bay and we got a quick glimpse of this fish, which we haven’t seen before. We are pretty sure it is an adult male Senator Wrasse, with very distinctive white ventral fins
We had never heard of the Hranice Abyss before catching sight of this article. Hranická Propast, in the Czech Republic, is the world’s deepest underwater cave with a depth of 1,325 feet (404m), as measured by an ROV. The cave was formed by hot, CO2-filled, mineral water bubbling up from an underground spring.

We love hearing about people using ROVs for safer inspection of vessels and other underwater assets. In this article, the US Navy inspected the USS George H.W. Bush with an ROV:
Check out our short video about some of the rivers, gardens and gorges hidden under the waves of Batemans Bay
We continue to explore amazing Batemans Bay on the South Coast of New South Wales, Australia, especially as life has slowed a bit with recent lock-down restrictions. The video in the link below shows some land-based features that must have submerged as the sea level rose over the last 20,000 years, and some of the life inhabiting those areas now.

We love hearing about the next generation of scientists and explorers! Congratulations Rehan!
Rehan noticed and studied with the help of his father the interaction between brown-spotted wrasse fish and common WA octopus. The fish follows the octopus around while it is foraging – called nuclear-follower behaviour – so the fish can score an easy meal, flushed out by the octopus.
