Kamchatka Marine Life Death Caused By Algae: Russian Scientist

The mass death of sea creatures in Russia’s Kamchatka region was caused by toxins from microalgae rather than man-made pollution, a senior Russian scientist said on Monday, citing preliminary findings of an investigation.

Locals on the volcanic peninsula in the Pacific raised the alarm in September as surfers experienced stinging eyes and sea creatures, including octopuses, seals and sea urchins, were found dead on the shore.

Scientists suggested that up to 95 percent of marine life living along the seabed in the affected area had died.

Conservation activists had raised concern that the source of the pollution could be a Soviet era storage ground for poisonous chemicals on Kamchatka that might have seeped out into the sea.

“I am sure that we are facing a large-scale phenomenon, but not an uncommon one for Kamchatka, called harmful blooming algae,” the vice president of Russia’s Academy of Sciences, Andrei Adrianov, told journalists

The increased temperature and acidification of our oceans over the next century have been argued to cause significant physical changes in an economically important marine species.

Scientists from the University of Plymouth exposed blue mussels (Mytilus edulis) to current and future levels of ocean acidification (OA) or warming (W), as well as both together – commonly known as OAW.

Initial comparison of mussel shells showed that warming alone led to increased shell growth, but increasing warming and acidification led to decreased shell growth indicating that OA was dissolving their shells.

However, analysis using cutting edge electron microscopy of the shell crystal matrix or ‘ultrastructure’ revealed that, in fact, warming alone has the potential to significantly alter the physical properties of the mussels’ shells, whereas acidification mitigated some of the

The first carnival of the animals and Early Palaeozoic marine life

Some of the world’s leading academics are discussing their work in a series of webinars organised by Durham University and the Chinese Academy of Sciences.

The series, Knowledge Across Borders, will bring together researchers who are outstanding in their fields of expertise to stimulate new, creative and critical thinking, open up new perspectives across cultures, deepen collaboration and share fresh insights.

The webinars will cover areas such as palaeontology, astronomy and science and technology as well as addressing interdisciplinary challenges.

The first webinar will be held on Thursday 29 October and will be presented by leading palaeontologists, Professor David Harper (Durham University) and Professor Renbin Zhan (Chinese Academy of Sciences/Nanjing Institute of Geology and Palaeontology).

Titled ‘The first carnival of the animals: Causes and consequences of the diversification of Early Palaeozoic marine life’, they will discuss how life has been evolving on our planet for some four billion years but

Ancient lizard’s long, crocodile-like snout suggests it carved out a niche in a competitive marine ecosystem — ScienceDaily

A new species of an ancient marine reptile evolved to strike terror into the hearts of the normally safe, fast-swimming fish has been identified by a team of University of Alberta researchers, shedding light on what it took to survive in highly competitive ecosystems.

Gavialimimus almaghribensis, a new type of mosasaur, was catalogued and named by an international research team led by master’s student Catie Strong, who performed the research a year ago as part of an undergrad honours thesis guided by vertebrate paleontologist Michael Caldwell, professor in the Faculty of Science, along with collaborators from the University of Cincinnati and Flinders University.

More than a dozen types of mosasaur — which can reach 17 metres in length and resemble an overgrown komodo dragon — ruled over the marine environment in what is now Morocco at the tail end of the Late Cretaceous period between 72 and 66 million

U.S. Marine Corps: Our Bases Will Be 5G Technology Test Sites

Marine Corps Air Station Miramar, Calif., is integrating emerging Verizon 5G Networking into its base operations as part of a decided effort to increase connectivity across the facility, assess new, high-speed networking technologies and better enable the use of unmanned systems.

“We are getting Fiber to more locations to find the right access points for 5G,” Nick Nilan, Director, public sector product development, Verizon, told The National Interest in an interview.

Nilan explained that the now-underway process, which involves extensive collaboration between U.S. military and commercial partners, reportedly creates networking as fast and efficiently as 1,000-times faster than existing systems.

“We operate from 30 Megabits per second up to 100 Megabits per second with a bandwidth north of 1 Gigabit per second, bringing computing elements closer to the edge,” Nilan explained.

The process, which is still very much in a nascent assessment phase, introduces a handful of new tactical possibilities

Laundry lint can cause significant tissue damage within marine mussels — ScienceDaily

Microscopic fibres created during the laundry cycle can cause damage to the gills, liver and DNA of marine species, according to new research.

Scientists at the University of Plymouth exposed the Mediterranean mussel (Mytilus galloprovincialis), found in various locations across the world, to differing quantities of tumble dryer lint.

They demonstrated that increasing the amount of lint resulted in significant abnormality within the mussels’ gills, specifically leading to damage of tissues including deformity, extensive swelling and loss of cilia. In the liver, the presence of lint led to atrophy or deformities leading to loss of definition in digestive tubules.

The increasing concentration of fibres also led to a reduction in the mussels’ ability to filter food particles from the seawater and a significant increase in DNA strand breaks in the blood cells.

Scientists say the precise causes of the effects are not wholly clear, but are likely to

Discovery originates in marine biological laboratory’s neurobiology course — ScienceDaily

The dialogue between neurons is of critical importance for all nervous system activities, from breathing to sensing, thinking to running. Yet neuronal communication is so fast, and at such a small scale, that it is exceedingly difficult to explain precisely how it occurs. A preliminary observation in the Neurobiology course at the Marine Biological Laboratory (MBL), enabled by a custom imaging system, has led to a clear understanding of how neurons communicate with each other by modulating the “tone” of their signal, which previously had eluded the field. The report, led by Grant F. Kusick and Shigeki Watanabe of Johns Hopkins University School of Medicine, is published this week in Nature Neuroscience.

In 2016 Watanabe, then on the Neurobiology course faculty, introduced students to the debate over how many synaptic vesicles can fuse in response to one action potential (see this 2-minute video for a quick brush-up on neurotransmission). To

Marine Heat Waves Are Putting Caribbean Fisheries In Hot Water

Small-scale fisheries are a critical component of the social and economic and fabric of coastal communities in the Caribbean and are key to the region’s food security, with annual fish consumption ranging between 10 and 35 kg/capita per year (FAO, 2014). But marine heat waves (MHW) or extended periods of anomalously warm ocean temperatures1 can have major impacts on marine biodiversity and ecosystems, and are a significant threat to the regional fisheries sector. A 2019 study in journal, Nature Climate Change, reports that coral reefs in the Caribbean have been among the hardest hit by heat waves, and the Food and Agriculture Organisation has found that the Caribbean fisheries sector is most vulnerable to climate change in the world. (Monnereau, 2017)

According to a September article in journal, Science, as global warming makes oceans hotter, marine heat waves (MHW) have become at least 20 times more likely. “The duration,

Marine biodiversity reshuffles under warmer and sea ice-free Pacific Arctic — ScienceDaily

Climate warming will alter marine community compositions as species are expected to shift poleward, significantly impacting the Arctic marine ecosystem.

The biodiversity of marine communities in the Pacific Arctic under future climate change scenarios highlights profound changes relative to their present patterns. Alterations in marine species distributions in response to warming and sea ice reduction are likely to increase the susceptibility and vulnerability of Arctic ecosystems. The findings, published by Hokkaido University researchers in the journal Science of the Total Environment, also suggest that there will be potential impacts on the ecosystem function and services.

Fisheries oceanographer Irene Alabia of Hokkaido University’s Arctic Research Center along with colleagues in Japan and the US investigated how future climate changes will impact the marine biodiversity in the Bering and Chukchi Seas. These seas extend from Alaska to Russia in the northern Pacific and southern Arctic oceans.

“This area forms a ‘biogeographical
