A long distance connection: polar climate affects trade wind strength in tropics
The impact of sea surface temperature variations in the tropical Pacific on global climate has long been recognized. For instance, the episodic warming of the tropical Pacific during El Niño events causes melt of sea ice in far-reaching parts of the Southern Ocean via its effect on the global atmospheric circulation. A new study, published this week in the journal Science Advances by an international team, demonstrates that the opposite pathway exists as well. (2020-11-20)

Synthesis study demonstrates phytoplankton can bloom below Arctic sea ice
Researchers used historical scientific studies, along with contemporary observations employing autonomous floats and robotic vehicles, to demonstrate that phytoplankton blooms occur under Arctic Ocean sea ice. Previously, scientists had assumed that was impossible due to low-light conditions, particularly when ice cover was thicker before climate change. The synthesis of more than half a century of research on under-ice blooms suggests that modern computer models underestimate the contribution of microscopic algae to the Arctic carbon cycle.

Late-season Arctic research cruise reveals warm ocean temperatures, active ecosystem
Arctic researchers have been visiting the Bering and Chukchi seas off Alaska for nearly 30 years, collecting information about the biological diversity of the watery world under the sea ice. This year, a late-season research cruise revealed a surprise. At a time of year when an ice-breaking ship is usually required to get to some of the data-gathering outposts, scientists found nothing but open water and an unusually active ecosystem. (2020-11-11)

Atmospheric rivers help create massive holes in Antarctic sea ice
Warm, moist rivers of air in Antarctica play a key role in creating massive holes in sea ice in the Weddell Sea and may influence ocean conditions around the vast continent as well as climate change, according to Rutgers co-authored research. (2020-11-11)

COVID-delayed Arctic research cruise yields late-season data
Researchers studying the Bering and Chukchi seas for three weeks in October found no ice and a surprisingly active ecosystem as they added another year's data to a key climate change record.

How ancient dust from the sea floor helps to explain climate history
Iron-containing dust can fuel ocean productivity. Researchers now show that dust travelled a long way in the South Pacific Region during the last Ice Age.

Ninety years of data shows global warming impacts on foundation of marine ecosystems
Phytoplankton are microscopic plants that underpin ocean productivity and provide 50% of the world's oxygen via photosynthesis. An investigation of a 90 year data set from a coastal station offshore from Sydney provides a unique opportunity to better predict the impact of global warming on future ocean phytoplankton communities, on biodiversity and ultimately fisheries production. (2020-11-01)

Hospital floors are hotspot for bacteria, creating route of transfer to patients
The floors of hospital rooms are frequently contaminated with antibiotic-resistant bacteria within hours of patient admission, creating a route of transfer of potentially dangerous organisms to patients, according to a study published today as part of the proceedings from Decennial 2020: The Sixth International Conference on Healthcare-Associated Infections. Decennial 2020, an initiative of the CDC and SHEA, was cancelled in March due to the pandemic. (2020-10-30)

The future is now: long-term research shows ocean acidification ramping up on the Reef
A new study has shown ocean acidification is no longer a sombre forecast for the Great Barrier Reef but a present-day reality. The study shows seawater carbon dioxide on the Reef has risen 6 per cent in ten years, matching the rate of carbon dioxide increases in the atmosphere. (2020-10-28)

Fish banks
Society will require more food in the coming years to feed a growing population, and seafood will likely make up a significant portion of it. At the same time, we need to conserve natural habitats to ensure the health of our oceans. It seems like a conflict is inevitable. (2020-10-28)

Leaving more big fish in the sea reduces CO2 emissions
Leaving more big fish--like tuna, sharks, mackerel and swordfish--in the sea reduces the amount of carbon dioxide (CO2) released into the Earth's atmosphere.This is because when a fish dies in the ocean it sinks to the depths and sequestrates all the carbon it contains with it. This is a form of 'blue carbon'. Big fish are about 10 to 15 percent carbon. (2020-10-28)

AWI researcher Peter Köhler has now discovered that the irregular appearance of interglacials has been more frequent than previously thought. His study makes a significant contribution to our understanding of Earth's fundamental climate changes. (2020-10-26)

The uncertain future of the oceans
Marine food webs and biogeochemical cycles react very sensitively to the increase in carbon dioxide (CO2) - but the effects are far more complex than previously thought. This is shown in a study published by a team of researchers from the GEOMAR Helmholtz Centre for Ocean Research Kiel in the journal Nature Climate Change. Data were combined from five large-scale field experiments, which investigated how the carbon cycle within plankton communities reacts to the increase of CO2. (2020-10-26)
