Coral reefs benefit from reduced land–sea impacts under ocean warming - Nature
Surveys of reef change are combined with a unique 20-year time series of land–sea human impacts and the results show that integrated land–sea management could help achieve coastal ocean conservat...

Coral reefs with high ecological integrity are able to quickly recover from extreme climate impacts. In our new study in Coral Reefs, we found high integrity Fiji reefs were able to rebound rapidly following a category 5 cyclone.

Today, we published a study long in the making on how upper and subsurface tropical Pacific waters responded (and maybe will adjust) to warmer global climate. Here’s the story of how we got here after 15 years. many authors but shout out @jfarmersalmanac.bsky.social

Persistent eastern equatorial Pacific Ocean upwelling since the warm Pliocene
Upwelling generates a nutrient-rich “cold tongue” in the eastern equatorial Pacific Ocean (EEP), with impacts on global climate, oceanic biological productivity, and the carbon cycle. The cold tongue ...

New paper led by @seaprinceaaron.bsky.social in @currentbiology.bsky.social looking at the threats deep sea mining poses for sharks, rays, and chimaeras. We found 30 species are threatened via various pathways including collector impact and plumes at depth and pelagic discharge plumes.
Figure 1: highlighting various pathways through which mining can impact sharks, rays, and chimaeras including collector impact and plumes, and discharge plumes. Figure 2: The diversity of sharks, rays, and chimaeras impacted by deep sea mining operations. Nearly 2/3 of these species are already at an elevated risk of extinction.

Over 70% of coral reefs in the tropical western Atlantic Ocean are projected to be in a state of erosion by 2040, increasing to nearly all reefs in 2100 if warming exceeds 2 °C above preindustrial levels, a study in Nature suggests. go.nature.com/48m9Y8F 🌊 🧪
This is figure 2, which shows reef accretion potential across western Atlantic reefs.

Check out the new paper on coral reef benthic depth zonation led by @bexturner.bsky.social from @sosbangor.bsky.social in @royalsocietypublishing.org. I've long been fascinated with how variable coral reef communities across the Pacific are. Nice to see it so coherently summarised. Well done Bex!

There is still hope to save irreplaceable coral ecosystems, but time is running out. Baby corals can ride ocean currents for hundreds of miles, but they can’t outrun climate change. And humans have a limited capacity to make new reefs in cooler waters. buff.ly/nY4jJs0 #WorldOceanDay
Coral reefs face an uncertain recovery from the 4th global mass bleaching event – can climate refuges help?
As baby corals float in the currents, they can expand their species’ range. But can they get to climate refuges fast enough to survive? A new study has good news and bad.
