epic news - a colleague from way back is part of a team that has just won a very fancy #Eureka science prize in Australia. Good one Claire! We've tried to spin up something similar here in Aotearoa but fallen some way short due to general lack of interest/funding.
They forecast #marineheatwaves and provide advice to coastal communities and industries on what to do to prepare...
the video is pretty good!

An underwater disaster: Marine heatwaves are cooking our ocean ecosystems – and will only become more common
" Marine heatwaves happen when the ocean remains abnormally hot for an extended period. While they may be invisible from the shore, their impacts can wreak havoc underwater – killing various kinds of coral, seagrass and fish." >>

The world’s oceans are the hottest on record for June – and El Niño is set to turn up the heat even more

A multi-stressor scenario for the ocean and waterway ecosystems:
* The ocean is 'cooked' by the combustion of fossil fuels.
* Add a generous heap of 'nutrient-rich' floodwaters (runoff) from farms and suburbia.
* Get a harmful algal bloom (HAB) disaster, killing bio-diverse marine life and threatening the hip pocket nerve of coastal dwellers.
"A survey found that Australians remained far more concerned about disasters such as bushfires and flooding than they did HABs, despite 22 million people living with seven kilometres of the coastline and climate change modelling predicting more frequent and severe blooms."
"The study also found Australians had a "relatively low prioritisation of disasters — and HABs in particular — when compared with everyday socio-economic concerns"...Cost of living and healthcare dominated respondents' concerns in Australia, while environmental and climate change-related risks were perceived as less pressing.' >>

Scientists Alarmed as #Whales Suddenly Going Silent
"When you really break it down, it’s like trying to sing while you're starving."
Aug 1, 10:27 AM EDT by Victor Tangermann
"Researchers are alarmed after noticing a significant drop in the number of vocalizations from #BlueWhales.
"As National Geographic reports, scientists used specialized underwater hydrophones, meaning the aquatic version of microphones, to record and trace the sounds of marine life, allowing them to analyze the impact human activity is having on various species.
"However, as detailed in a study published in the journal PLOS One, devastating heat waves have triggered worrying changes over the past decade, allowing #ToxicAlgae to bloom and undermine food sources for whales.
" 'It caused the most widespread poisoning of marine mammals ever documented,' coauthor and Monterey Bay Aquarium Research Institute biological oceanographer John Ryan told NatGeo. 'These were hard times for whales.'
"As a result, blue whale vocalizations dropped by almost 40 percent, according to the study, with populations of #krill and #anchovy collapsing.
" 'When you really break it down, it’s like trying to sing while you're starving,' Ryan explained. 'They were spending all their time just trying to find food.' "

@GhostOnTheHalfShell I did a feature on #kelp last year: https://proseandpassion.blogspot.com/2024/11/brown-algae-and-blue-carbon.html and one on #marineHeatwaves the year before, https://proseandpassion.blogspot.com/2023/08/our-planet-is-in-hot-water.html I think I mentioned similar problems of kelp being replaced by algae as the water warms in one of these.
"The authors note that one group of researchers found that the number of such #heatwaves in 2023–2024 was 240% higher than any other year in recorded history. They also note that the more often such heat waves occur, the more difficult it is for affected areas to recover."

I know we're land dwellers, but this is a water planet, and we need to pay attention to what's happening with the water.
Surge in marine #heatwaves costs lives and billions in storm damage – study
"Floods, whale strandings and coral bleaching all more likely, say researchers, as 10% of ocean hits record high temperatures in 2023-24.
One of the most surprising findings in the study, said Smith, was “how much [#MarineHeatwaves] accentuated storms on land and the number of people that were hit by that – hurt, lost possessions, [suffered a] monetary impact or lost their lives”. "
Another coral bleaching event.

Occasionally, and only partly to wind up my remote sensing colleagues, I describe #satelliteData as "basically a model". Per definition satellite data is electromagnetic radiation (at different frequencies/wavelengths) that has passed through (some of) the earth's atmosphere and then run through a model to give us "satellite data".
Not an original point but it does explain some interesting findings in @micefearboggis' latest on #MarineHeatwaves
