Marine heatwaves decimate sea urchins, mollusks and more at Rottnest
Curtin University researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as mollusks and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 percent bet.....»»
Environmental factors influence Southeast Brazil"s coastal biodiversity more than ecological processes, study finds
Sea surface temperature, wave energy and freshwater discharge from rivers influence the abundance and size of the marine organisms that inhabit rocky shores along the coast of Southeast Brazil more than ecological processes such as competition and pr.....»»
Scientists long urged NASA to search for signs of life near Jupiter; now it"s happening

Study reveals relationship between nitrogen-cycling microbial communities and nitrogen removal
Excess nitrogen (N) input to the inland water bodies and marine ecosystem has contributed to a cascade of environmental issues, so N removal pathways are critical in aquatic and terrestrial ecosystems for maintaining homeostasis. Associated functiona.....»»
Spotted handfish genome sequenced for the first time
Scientists from CSIRO, Australia's national science agency, have sequenced the first ever full genome of the rare and elusive spotted handfish (Brachionichthys hirsutus)—a critically endangered marine fish endemic to Tasmania......»»
Australia moves to expand Antarctic marine park
Australia moved Tuesday to protect a swathe of ocean territory by expanding an Antarctic marine park that is home to penguins, seals, whales and the country's only two active volcanos......»»
Hurricane Helene"s reach was shocking, another example of how climate change "is here and now," scientists say
Many people were stunned to see the intense flooding and devastation caused by Hurricane Helene in western North Carolina communities, located inland and tucked thousands of feet above sea level in the Blue Ridge Mountains......»»
How future heat waves at sea could devastate UK marine ecosystems and fisheries
The oceans are warming at an alarming rate. 2023 shattered records across the world's oceans, and was the first time that ocean temperatures exceeded 1°C over pre-industrial levels. This led to the emergence of a series of marine heat wave events ac.....»»
Mathematicians and climate researchers build new models for understanding polar sea ice
Polar sea ice is ever-changing. It shrinks, expands, moves, breaks apart, reforms in response to changing seasons, and rapid climate change. It is far from a homogenous layer of frozen water on the ocean's surface, but rather a dynamic mix of water a.....»»
AI models identify marine biodiversity hotspots in Mozambique
A new study led by staff from the Wildlife Conservation Society (WCS) in East Africa has used a predictive artificial intelligence (AI) algorithm to confirm the location of previously-unmapped high marine biodiversity areas along Mozambique's extensi.....»»
Bottlenose dolphins "smile" at each other while playing, research shows
Dolphins are extremely playful, but little is known about how they—and other marine mammals—communicate during playtime. New research published October 2 in the journal iScience shows that bottlenose dolphins (Tursiops truncates) use the "open mo.....»»
Push to map Great Lakes bottom gains momentum amid promises effort will help fishing and shipping
Jennifer Boehme grew up scouting beaches around her home in St. Petersburg, Florida, for whatever she could find. Rocks, sand dollars, coquina mollusks—anything the ocean gave up......»»
Scientists highlight overlooked threats to Arctic coasts amid climate change
As climate change rapidly transforms Arctic marine systems, the dramatic image of a polar bear struggling on a melting ice floe has become symbolic of the region's environmental crisis. But scientists argue that coastal Arctic ecosystems are undergoi.....»»

DNA technology enables molecular monitoring for marine change and threats
New DNA technology promises to improve efforts to monitor marine life in the Southern Ocean, and detect the presence of non-native marine species close to Antarctica......»»
Raman spectroscopy study decodes symbiotic interactions in marine algae
In a recent study, researchers from the Leibniz Institute of Photonic Technology (Leibniz IPHT) and the Friedrich Schiller University Jena have shown how they can non-invasively and non-destructively investigate the growth and interactions of the gre.....»»
New assessment suggests Anthropocene started in the 1950s
A team of Earth scientists from the Center for Marine Environmental Studies, the University of Tokyo, The Australian National University, Matsuyama University, Kyoto University, and Shimane University, has found, via a new assessment, that the 1950s.....»»
The biological marvels of the seabed are being mined to create commercial products—here are the risks
Thousands of genes from deep-sea marine life are being used to create new commercial products ranging from pharmaceuticals to cosmetics. Genes are segments of DNA that provide instructions for making other molecules that are essential for the structu.....»»
Climate change accelerates vulnerability and loss of resilience of a key species for the Mediterranean ecosystem: Study
A study by the University of Barcelona has analyzed the ability of red gorgonians (Paramuricea clavata), a key species for the Mediterranean marine ecosystem, to resist and recover after marine heat waves......»»
"Remarkable" marine animal forests found around Wellington"s coast in central New Zealand
Marine animal forests rich in sea life have been found in the shallow waters around Te Whanganui-a-Tara Wellington......»»
Marine dust identifies 1.5 million year Oldest Ice near South America
Earth's climate has experienced major shifts over its billions of years of history, including numerous periods where ice proliferated across the planet. Today, ice cores can be a valuable resource for understanding these periods of Earth's history as.....»»
