Marine experts across the world are working together to create a global catalog of sounds of underwater life, to monitor the changing environment and inform marine conservation. The open-access Global Library of Underwater Biological Sounds (GLUBS) will use artificial intelligence (AI) and citizen science to capture signature sounds from mammals like whales, as well as invertebrates, fish and crustaceans.
ROV finds wreck after 130 years
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.

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.

ROV investigating Fukushima Reactor
An ROV was deployed to investigate Japan’s Fukushima nuclear power plant that was damaged in 2011. The ROV captured images of what appears to be mounds of nuclear fuel that melted and fell to the bottom of the most damaged reactor.
This investigation was the first attempted since 2017 when an ROV was unable to capture any images because of extremely high radiation levels. This year, the robotic vehicle measured radiation of 2 sievert at one location, which is still fatal to humans.
