Underwater Climate Refuges: Designing Technological Sanctuaries to Protect Marine Biodiversity from Warming

As our oceans face unprecedented warming due to climate change, the urgency to protect marine biodiversity has reached a critical point. With ecosystems and species at risk, innovative solutions are emerging to preserve our oceans’ richness for future generations. Among these transformative ideas are underwater climate refuges—cutting-edge technological sanctuaries designed to shield marine life…

Singer-songwriter Ellie Goulding spoke to the Nature+ Newsroom at COP27 in Sharm el-Sheikh, Egypt, on November 16 about the health of oceans, specifically the health of coral reefs. She lamented, ‘The idea that my kid, my son, and everyone’s kids are gonna grow up, you know, learning about corals in books, but never be able to see them for themselves, that is one of the saddest things in the world.’

This video was created in collaboration with Nature's Newsroom.

Early Adopters of NASAs PACE Data to Study Air Quality Ocean Health

From the atmosphere down to the surface of the ocean, data from NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) satellite benefits ecosystems, human health, and underrepresented communities. Years before the launch in February 2024, mission leaders from NASA teamed with dozens of applied scientists and environmental professionals to prepare for the many practical uses that […] from NASA https://ift.tt/27XSoqe

2 Million and Counting: The Deep Sea’s Astonishing Biodiversity

Did you know there could be over 2 million species living in the deep sea? The dark and mysterious world of the deep sea holds countless secrets, and scientists estimate there could be millions of undiscovered species living down there! What bizarre creatures might be waiting to be found? What role does the deep sea play in our planet’s health? Explore the fascinating – and sometimes weird! –…

Practical measures to address the problem of ghost gear.

Abandoned, lost or otherwise discarded fishing gear, known as ‘ghost gear,’ is a global problem that severely impacts ocean health.

‘Ghost gear’ is generally made of plastic and not only pollutes the ocean but also harms marine animals. The Food and Agriculture Organization (FAO) has produced documentation to help countries with their legal responses to the issue.

Excerpts:

The ocean is much less reflective than the land and soaks up more of the direct energy from sunlight. But as greenhouse gases trap more of the energy that’s reflected back—allowing less to escape to space—the ocean tries to balance itself with the heat in the atmosphere above.

[...]

A study in January found the ocean gained 10 ZJ more in 2022 than the year before—enough heat to boil 700 million tea kettles every second. Compared with the ocean, according to a study in January, the atmosphere has held on to about 2 percent of the extra heat caused by global heating since 2006.

[...]

Sloyan says the ocean has acted like the planet’s air conditioner, relentlessly absorbing extra heat. “But that air conditioner isn’t just passive. It is not a free service. Adding that heat has come with ocean acidification, rising sea levels and changes in the frequency of extreme weather.”

The effects of the extra heat are almost everywhere. As the ocean heats up, it expands, pushing up sea levels around the globe. Just over one-third of the rise in global sea levels is down to thermal expansion.

More heat means more marine heatwaves that have devastated marine ecosystems, causing bleaching on coral reefs and killing underwater plants that act like forests, providing habitats for marine life and acting as nurseries for fisheries.

[...]

Ocean heating could also radically alter marine food webs, with warmer conditions favoring smaller species and algae at the expense of the larger species that humans tend to eat.

In the deep ocean, where species have adapted to stable temperatures, scientists have said warming there in the coming decades could devastate marine life.

Around the tropics, where oceans are warmest, scientists have found species are already migrating towards the poles to find cooler waters. But with no other species able to take their place, this leaves behind waters stripped of marine life.

In places like the Mediterranean, where land blocks a route to cooler waters, Professor David Schoeman says many species will run out of ocean. “Fish can’t just climb out of the water so they may have to go deeper,” says Schoeman of the University of the Sunshine Coast in Australia, who helped coordinate the latest UN climate assessment’s work on the ocean.

But if species go deeper to survive the heat, this could present another problem. Schoeman says waters near the surface easily mix with the air above to provide enough oxygen for marine life. But as deeper waters warm they hold less oxygen, potentially cutting off another survival option for some species.

[...]

“By absorbing all this heat, the ocean lulls people into a false sense of security that climate change is progressing slowly,” he says. “But there is a huge payback. It’s overwhelming when you start to go through all the negative impacts of a warming ocean.”

“There’s sea level rise, coastal inundation, increased floods and drought cycles, bleached corals, intensification of cyclones, ecological impacts, melting of ice at higher latitudes in the coastal margins—that gives us a double whammy on sea level rise.”

The Vital Role of Deep Ocean Water Circulation in Sequestering Carbon and Maintaining the Health of the Sea

The ocean is a vast and complex ecosystem that plays a critical role in regulating the Earth’s climate. One of the most important processes that occur in the ocean is the circulation of deep ocean water. This circulation is considered vital for the health of the sea and plays an important role in sequestering carbon absorbed from the atmosphere. In this article, we will explore the circulation…

Mapping the Underwater World: The Role of LiDAR in Oceanography

In the quest to explore and understand the mysteries of the ocean, technology plays a pivotal role in unveiling the hidden wonders beneath the waves. Among the array of cutting-edge tools at our disposal, LiDAR (Light Detection and Ranging) has emerged as a go-to technology, enabling scientists to map the seafloor, study underwater topography, and reveal geological features that were once…
