  • Deep thinking on the world’s oceans

    Changes in deep ocean conditions affect global climate, with deep warming contributing to sea-level rise and the deep ocean absorbing atmospheric carbon dioxide. To assess change, researchers determine the amount of energy (in the form of heat), water and gases (including carbon dioxide), entering and exiting the ocean. They rely on valuable but infrequent deep ocean measurements from ships, ...

  • Microplastics discovered in the deep, open ocean

    A unique study by scientists at the National Oceanography Centre (NOC) will provide valuable new insights into the concentrations of microplastics in the open ocean from surface to the sea bed. Professor Richard Lampitt and Dr Katsia Pabortsava, who lead microplastic research at NOC, said “There is considerable uncertainty about the concentration and characteristics of the many ...

  • Deep-ocean sentinels on northern climate watch

    Up to 3,000 metres tall and carrying an array of special marine sensors, the moorings were deployed earlier this month as part of an international collaboration to monitor the Timor Passage and Ombai Strait – two strategic deep ocean channels which act as 'chokepoints' in the global system of ocean currents. Valued at over $1 million, the moorings were deployed as part of Australia's ...

  • Onset Announces Deep Ocean Temperature Data Logger

    Onset Computer Corporation (http://www.onsetcomp.com), the world leader in data loggers, today announced the HOBO U12 Deep Ocean Temp logger, a new data logger for tracking ocean ...

  • Southern Ocean winds open window to the deep sea

    The researchers’ findings – published on-line today in Nature Geoscience – provide new insights into natural processes which have a major influence on the rate of climate change. The surface-mixed layer is a crucial pathway between the atmosphere and the deeper layers of the ocean. Changes in the depth of the mixed layer can affect air-sea exchange, carbon and heat storage in the ocean, and the ...

  • Oceans are heating up at the double

    Ocean temperatures first collected during one of the great 19th-century voyages of exploration confirm one of the consequences of climate change: humans have managed to warm even the deepest parts of the ocean. A new study in Nature Climate Change calculates that the amount of heat absorbed by the ocean has doubled in the last 18 years. A third of this heat has ...

  • Tracing CO2 elements in the ocean

    The surface waters of the vast Southern Ocean are suffering from 'marine anaemia' – a serious deficiency in the micronutrient iron. Just as iron deficiency negatively affects the health and productivity of humans and other land-based creatures, so it affects the phytoplankton (microscopic marine plants) existing in the oceanic realm. The environmental consequences of this condition restrict ...

  • Are the world’s oceans on the brink of disaster?

    An international panel of marine experts warns in a report released today that the world's ocean is at high risk of entering a phase of extinction of marine species unprecedented in human history. The preliminary report arises from the first ever interdisciplinary international workshop to consider the cumulative impact of all stressors affecting the ocean. Considering the latest research across ...

  • Harnessing energy from the oceans

    Forever moving - our restless oceans have enough energy to power the world. As long as the Earth turns and the moon keeps its appointed cycle, the oceans will absorb and dissipate vast amounts of kinetic energy - a renewable energy resource of enormous potential. But harnessing this resource has proven more difficult than first thought. In this the latest installment of the GLOBE-Net Series on ...

  • Study Shows Widespread Climate Changes Underway in B.C`s Oceans Affecting Fisheries, Deep Sea-Diversity and Coastal Habitats

    A newly-released report by WWF and the Canadian Parks and Wilderness Society (CPAWS) reveals that the effects of climate change are reducing fish habitat on B.C.'s coast, threatening the province's lucrative groundfish and shellfish fisheries. The study is the first regional synthesis of its kind to document observed and expected impacts of a changing global climate on B.C's marine ecosystems and ...

  • Shedding light on the cinderellas of the deep sea

    Ocean sponges from shallower waters have already been shown to be valuable sources for new medicinal drugs to treat cancers and for antibiotics, and it is expected that deepwater sponges will be equally valuable, if not more so. A groundbreaking new report, Deep-sea Sponge Grounds: Reservoirs of Biodiversity, which consolidates knowledge on the biology and ecology of deep-water sponge grounds, ...

  • CO2 removal cannot save the oceans

    Greenhouse-gas emissions from human activities do not only cause rapid warming of the seas, but also ocean acidification at an unprecedented rate. Artificial carbon dioxide removal (CDR) from the atmosphere has been proposed to reduce both risks to marine life. A new study based on computer calculations now shows that this strategy would not work if applied too late. CDR cannot compensate for ...

  • Iron’s mixed blessing for health of oceans

    Technology’s answer to climate change in a world in which humans go on releasing carbon dioxide in the atmosphere has just had another setback. The idea of fertilising the planet’s oceans with iron filings to stimulate green growth and turn the oceans into a carbon sink isn’t so simple as hoped. Two studies – both involving experiments at sea – have ...

  • Ocean fertilization experiment draws fire

    A German research ship laden with 20 tonnes of iron sulphate has whipped up a storm of protest as it sails towards the Antarctic, where it intends to dump its cargo into the ocean. Scientists on thePolarstern, which set sail from Cape Town in South Africa on 7 January, plan an ocean fertilization experiment that some argue will violate international law. But the scientists say that it will yield ...

  • New source of ocean methane discovered

    Scientists searching for an explanation for high levels of the potent greenhouse gas methane in the oceans have discovered a new means of production, which could explain the source of previously unaccounted for methane. The discovery has great significance for understanding the ocean's role in global warming. Methane is a potent greenhouse gas that has contributed approximately 20 per cent to the ...

  • Scientific sub makes deep-sea discoveries

    The collaborative voyage of US and Australian researchers was led by chief scientists Dr Jess Adkins from the California Institute of Technology and Dr Ron Thresher from CSIRO’s Climate Adaptation and Wealth from Oceans Flagships. “We set out to search for life deeper than any previous voyage in Australian waters,” Dr Thresher says. “We also gathered data to assess the threat posed by ocean ...

  • Deep concern over invisible threat to Antarctic glaciers

    The Antarctic ice shelf is under threat from a silent, invisible agency – and the rate of melting of glaciers has trebled in the last two decades. The ocean waters of the deep circumpolar current that swirl around the continent have been getting measurably warmer and nearer the ocean surface over the last 40 years, and now they could be accelerating glacier flow by melting the ...
