NOAA uses Degree Heating Weeks to predict #coralbleaching. For mobile species, like fish and turtles, 'thermal displacement' has been suggested as a metric to characterize the effects of marine #heatwaves.
A functioning #coralreef ensures a constant supply of beach sand through cycles of erosion, deposition & growth. This supply function may make coastlines more resilient to #sealevelrise by providing building material to waves that shape island contours.
#ToDo: search for whales in #GoogleEarth imagery.
Four #remotesensing technologies helped uncover widespread #IUU fishing by vessels originating from Chinese ports & operating in waters between the Koreas, Japan & Russia.
>700 volunteers helped screen ~18,000 hrs of video footage for #sharks.
Conclusion? Sharks are ‘functionally extinct’ from 1 in 5 #coralreefs.
Lacking business, tour operators helped confirm severe #coralbleaching in Western Australia, including the worst bleaching on record at Rowley Shoals. https://theconversation.com/with-no-work-in-lockdown-tour-operators-helped-find-coral-bleaching-on-western-australias-remote-reefs-142644?utm_source=twitter&utm_medium=bylinetwitterbutton via @ConversationEDU
New nuisance alga is smothering reefs in the Pacific:
In August 2019, researchers diving in #Papahānaumokuākea Marine National Monument saw mats of a red alga they did not recognize, smothering the native corals. Learn more about this undescribed species in our latest story.

#Seagrass meadows store carbon ~30x faster than most terrestrial forests.
Their disappearance from Australian coastlines since the 1950s has resulted in CO2 emissions equivalent to 5 million cars in a year.

The @LivingOceansFdn is proud to release our findings from the #GlobalReefExpedition on the state of #CoralReefs in the #SolomonIslands.
We conducted >1k #reef surveys and created maps of >3k sq km of reefs in the Solomon Islands. @UMiamiRSMAS

Coral skeletons efficiently direct sunlight to their photosynthetic algae. 3D bio-printing technologies can now mimic their shapes down to the micron level, providing new opportunities to study #coralbleaching in the lab.

#CitizenScientist sailors have kept this mission going since 1931. Their data inform #climatescience, #microplastics tracking & other research.
#Drone footage helped marine biologists count nesting #seaturtes off the #GreatBarrierReef. How many? About 64,000.
"All the scientists interviewed for this article noted that mitigating #climatechange is the only long-term, sustainable solution to conserve and restore #coralreefs."

Which marine ecosystem covers only 0.1% of the ocean floor but stores up to 18% of the world's oceanic carbon?
New @UNEP report highlights role of #seagrass in global human wellbeing.
