GEOMAR participates in international climate change conference COP28 and supports the “Dubai Ocean Declaration”. Partnering with other leading scientific and stakeholder organisations, GEOMAR Helmholtz Centre for Ocean Research Kiel participates in this year’s United Nations climate change conference in Dubai, United Arab Emirates. GEOMAR contributes to the Ocean Pavilion, a central hub for leveraging ocean science and solutions for the climate crisis coordinated by the Woods Hole Oceanographic Institution (WHOI) and Scripps Institution of Oceanography. Today, the partners call on…

The ocean surface is 30 percent more acidic today than it was in 1800, much of that increase occurring in the last 50 years – a rising trend that could both…

During a science cruise in 2008, researchers from British Antarctic Survey (BAS) and the University of East Anglia (UEA), in collaboration with colleagues from…

A new array of ocean robots has begun working deep in the Indian Ocean to help scientists understand Australia’s changing climate.

“This is a key region for the global climate system and installation of the robots will provide our best coverage to begin to understand how the Indian Ocean affects our climate,” says CSIRO’s Dr Gary Meyers.

Cycling between the surface and a depth of two kilometres every 10 days, the ocean robots are sampling conditions in a region thought to

In parts of the Southern Ocean, the striations — also known as ocean fronts — produce alternating eastward and westward accelerations of circulation….

Scientists from Scripps Institution of Oceanography at UC San Diego and engineers at NOAA’s Pacific Marine Environmental Laboratory (PMEL) are in the initial…

The research shows that, between the 1990s and 2010, acidified waters expanded northward approximately 300 nautical miles from the Chukchi slope off the coast…

Vertical motions associated with this current have been responsible for transporting a substantial fraction of the anthropogenic carbon dioxide emissions from…

62% of the earth’s surface is found more than 1000 meters below the ocean. No standard, manned submersible could withstand the absolute darkness and extreme…

Sea water being churned in the ocean off Antarctica may be having a greater effect on global patterns of ocean movement than previously thought, according to new research reported in this week’s edition of the international journal Science (9 January 2004).

The research, lead by scientists from the University of East Anglia (UEA), shows that “remarkably intense and widespread” mixing of water in the Southern Ocean occurs over large regions where the ocean bed is rough.

The main aut

In so doing, Dr Clara Hoppe and her team have overturned the widely held assumption that sinking pH values would stimulate the growth of these unicellular…

Although microbes that live in the so-called “dark ocean”—below a depth of some 600 feet where light doesn’t penetrate—may not absorb enough carbon to curtail…

The seamount was discovered in August when James Gardner, research professor in the UNH-NOAA Center for Coastal and Ocean Mapping/Joint Hydrographic Center,…

Dumping iron in the ocean is known to spur the growth of plankton that remove carbon dioxide, a greenhouse gas, from the atmosphere, but a new study indicates iron fertilization may not be the quick fix to climate problems that some had hoped.

Scientists have quantified the transport of carbon from surface waters to the deep ocean in response to fertilizing the ocean with iron, an essential nutrient for marine plants, or phytoplankton. Prior work suggested that in some ocean regions

A large portion of the carbon dioxide emitted when humans burn fossil fuels, for instance, is taken up and stored in the ocean via a set of processes that make…

Ocean Networks Canada, an initiative of the University of Victoria, will extend its ocean monitoring outside Canadian waters. Canadian and European experts in polar observation are joining forces in a new partnership that will see Ocean Networks Canada (ONC) operating a subsea observatory at the Spanish Antarctic Station, providing year-round, near real-time data on ocean conditions there. This is the first time that ONC will extend its ocean monitoring outside Canadian waters. This partnership between ONC, a University of Victoria initiative, and…

Never before have so many scientists conducted research on what impacts the declining pH value of seawater has on animals and plants in the ocean. The experts…

Using future projections from the latest generation of Earth System Models, a recent study published in Science Advances found that most of the world’s ocean is steadily losing its year-to-year memory under global warming. Compared with the fast weather fluctuations of the atmosphere, the slowly varying ocean exhibits strong persistence, or “memory”, meaning the ocean temperature tomorrow is likely to look a lot like it does today, with only slight changes. As a result, ocean memory is often used for…

How does ocean alkalinity enhancement affect marine life? In a multi-week experiment starting today, scientists led by GEOMAR Helmholtz Centre for Ocean Research Kiel investigate if the addition of rock powder is able to help the ocean absorb carbon dioxide from the atmosphere and mitigate climate change. For this purpose, twelve enclosed test tanks are set up in the water in front of the Kiel Aquarium. With the help of controlled experiments, the researchers want to better assess what effects…

After comparing sites in both oceans, they found the Arctic site to be more acidic, warmer during the summer months, and have fewer nutrients; those…
