The 172 foot schooner-barge Atlanta was found by sonar and ROV at the bottom of Lake Superior last year, after having sunk in a brutal storm on May 4th, 1891.

Red Morwong
These striking fish, gracefully suspended in the blue waters off the NSW coast, are Red Morwong. We were pleasantly surprised to see this calm and colourful school, and that our ROV was close enough to illuminate the eye-catching patterns across their faces.
Green Moray Eel
This resident Green Moray Eel greeted our ROV on a dive in Batemans Bay, NSW not long ago. Green Moray Eels are just one of more than 160 different species of Moray Eel around the world. Believe it or not, this green eel is not actually green – it is brown in colour. The bright yellow or green colour we see is due to a mucus that covers its body to protect it from parasites and injury from the rough surroundings of reefs and shorelines in which it lives. Maybe it should be known as Slimy Green Moray Eel?
NOAA’s 2022 Sea Level Rise Report
The National Oceanic and Atmospheric Administration recently released its Technical Report on the expected rise is sea levels in the next 30 years and its impact on U.S. states and territories. You can find the report here: 2022 Technical Report, Data, FAQs
Key points in the report:
- Sea levels are going to rise by 10 – 12 inches (25 – 30 cm) by 2050
- Sea level rise is affected by climate change and greenhouse gas emissions
- The frequency of extreme flooding events will increase. For example, moderate flooding events, where damage is likely to occur, are expected to increase from ~1 to ~4 times per year
This report is certainly motivating us to look more closely at how we can reduce our overall carbon footprints.
Rain… from underwater
There has been soooo much rain in Sydney lately that we decided to try something a little different and turn our ROV’s gaze upwards for a change. Result – heavy rain… as viewed from under the surface
