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.....»»
New tool skillfully predicts marine habitat shifts
As global temperatures rise, so do ocean temperatures. The ocean absorbs about 90% of the world's excess heat, and this leads to changes to the marine environment that go beyond temperature, making some areas uninhabitable for some marine species......»»
Frequent marine heat waves in the Arctic Ocean will be the norm, says new study
Marine heat waves will become a regular occurrence in the Arctic in the near future and are a product of higher anthropogenic greenhouse-gas emissions, according to a study just released by Dr. Armineh Barkhordarian from Universität Hamburg's Cluste.....»»
Researchers discover new species of mussel that lives in an ancient undersea forest
A Northeastern marine scientist has discovered a new species of tiny mollusk that lives in an ancient, submerged cypress grove called the Alabama Undersea Forest......»»
Why is boat company Brunswick attracting so many automotive people?
The quest for autonomy and electrification is spilling over into the marine industry, and auto managers are providing the expertise......»»
Mapping Australia"s marine estate: Seafloor surveillance for biodiversity management
Global marine biodiversity is continually being threatened by oceanographic changes linked to both global warming and anthropogenic activities that degrade the ambient environment for marine organisms. Australia's oceanographic biodiversity is global.....»»
Study shows marine heat waves have significant impact on microorganisms
A new study led by Australia's national science agency, CSIRO, shows that marine heat waves (MHWs) are altering the microorganism communities that form the base of the marine food chain, disrupting coastal ecosystems. The article "A marine heat wave.....»»
Brexit-induced spatial restrictions reveal alarming increase of fishing fleet"s carbon footprint
In a study published in Marine Policy, researchers have unveiled striking evidence that fisheries management decisions such as spatial fisheries restrictions can increase greenhouse gas emissions......»»
Engineers unmask nanoplastics in oceans, revealing their true shapes and chemistry
Millions of tons of plastic waste enter the oceans each year. The sun's ultraviolet light and ocean turbulence break down these plastics into invisible nanoparticles that threaten marine ecosystems......»»
Australia scientists pluck rare handfish from ocean due to climate risk
Scientists have collected 25 extremely rare red handfish from the ocean off Australia, hoping to protect the struggling species from warming seas, human-caused habitat changes and ravenous urchins......»»
Global warming caused widespread ocean anoxia 93 million years ago, deep-sea sediments research suggests
Marine anoxia is characterized by the oceans being severely depleted in dissolved oxygen, making them toxic and thus having devastating impacts on the organisms inhabiting them. One such event, known as Oceanic Anoxic Event 2 (OAE2), occurred ~93.5 m.....»»
Pollutants from aerosols and river runoff are changing the marine phosphorus cycle in coastal seas, finds study
New research into the marine phosphorus cycle is deepening our understanding of the impact of human activities on ecosystems in coastal seas. The research, co-led by the University of East Anglia, in partnership with the Sino-UK Joint Research Centre.....»»
How the seabed could be a refuge for gorgonian coral forests threatened by marine heat waves
Over the last 20 years, the world's oceans have experienced a significant increase in episodes of high-sea surface temperatures, known as marine heat waves......»»
Genomic analysis sheds light on how seagrasses conquered the sea
Seagrasses provide the foundation of one of the most highly biodiverse, yet vulnerable, coastal marine ecosystems globally. They arose in three independent lineages from their freshwater ancestors some 100 million years ago and are the only fully sub.....»»
Marine biologist shows how computers are quick and reliable in counting seals
Computers can count seals from aerial photographs with lightning speed and reliability. Based on their spatial patterns, the tiny dots on the aerial images can even be assigned to one of the two major species of seals in the Wadden Sea. That is shown.....»»
Marine biologist finds unexpected biodiversity on the ocean floor
Hydrothermal vents and manganese nodule fields in the deep oceans contain more biodiversity than expected, according to the thesis that NIOZ-marine biologist Coral Diaz-Recio Lorenzo will defend at Utrecht University on January 26......»»
New tech could help reduce ecological impact of underwater noise pollution
A new system that harnesses the power of AI to accurately model how sound waves travel underwater could help reduce the impact of noise pollution on marine life......»»
Using photos to create 3D models helps us understand, and protect, complex marine environments
Measuring the impact of different events, such as marine heat waves, on the abundance of marine organisms is not easy. Biological communities naturally change over time and between different locations......»»
Humpback whales move daytime singing offshore, research reveals
Humpback whale singing dominates the marine soundscape during winter months off Maui. However, despite decades of research, many questions regarding humpback whale behavior and song remain unanswered. New research has revealed a daily pattern wherein.....»»
Research maps potential risks to iconic marine wildlife
The areas used by six threatened marine megafauna species overlap with a myriad of human activities in the waters of Australia's north west, a collaborative study led by the Australian Institute of Marine Science (AIMS) has revealed......»»
Dark black eggs found on ocean floor represent deepest free-living flatworms ever observed
A pair of marine scientists at Hokkaido University, in Japan, has found evidence of the deepest free-living flatworms ever observed. In their study, published in the journal Biology Letters, Keiichi Kakui and Aoi Tsuyuki, identified flatworm eggs fou.....»»
