Curious about #lightpollution impacts underwater and in our urban ecosystems? Join this free webinar tomorrow, 10.30am Sydney time with A/Prof Mariana Mayer Pinto 🌊🌐🧪😊💡

Upcoming free webinar on marine impacts of light pollution! A/Prof Mariana Mayer Pinto will present an online webinar on the impacts of #lightpollution on #marineecology on the 17th February 2026 at 10:30 am AEDT, organised by the Australasian Dark Sky Alliance 🧪💡🌐🌊 tinyurl.com/light-webinar

Can seagrass restoration be more successful when we mimic existing seagrass beds? 🌱 Another talented PhD student of ours, Ann Nielsen spoke at the UNSW Big Ideas festival late last year. Watch here! 🌊🌐🧪 #marineecology #seagrass #posidonia www.youtube.com/watch?v=3mJJ...

What do light pollution and saltmash have in common? They are both found along the Cooks river! Milly Caley and Dana Lanceman will give a talk on Feb 17th on light pollution in marine environments and saltmarsh and mangrove restoration for the Cooks River Valley association 🌊🧪🌐😊💡🌱

Light pollution is an underappreciated and growing threat to marine #biodiversity. It already affects ~22% of global coastlines and can reach the seafloor. This video, made with #UNSW, #ADSA, and #DCCEEW, highlights why marine #lightpollution matters 🌊🌐🧪 #ALAN 💡 www.youtube.com/watch?v=Rtd7...

Wonderful illustration by Hyunh Kim from Mariana's talk at the Valuing Darkness Symposium. Over 20% of the world’s coastlines experience #lightpollution, yet we have limited knowledge of its impacts on #marineecology and key habitat-forming organisms 🧪🌊💡🌐 Read more here: tinyurl.com/ADSA-conf

A hand drawn image in black and white pen showing a cross-section of a coastal landscape illuminated by light pollution. The top of the image shows vertical light lines extending into the sky, above five semi-circles that look like hills. Below these hills are horizontal lines and circles that are emitting yellow texta light lines downwards. Moving down the page, under these yellow lines is the sea surface and small boats. Under the waters surface are schools of fish outlined, and at the bottom of the page are seaweeds extending up to the surface.
