Russ E. Davis died on 9 June 2022 at the age of 81. A physical oceanographer at the Scripps Institution of Oceanography at UC San Diego, he was one of the great pioneers of contemporary oceanography.
Russ E. Davis is a leading name in the international community of oceanographers, undoubtedly recognised as a key player in the advancement of knowledge in recent decades on the role of the ocean in climate and on the dynamics of the upper ocean.
Thanks to his boldness and inventiveness, Russ E. Davis was responsible for the birth of the newest and most revolutionary generation of ocean observation instruments in history. He has actively contributed to the work of observing the oceans with satellites. Above all, in the 1990s he developed the famous SOLO (Sounding Oceanographic Lagrangian Observer) autonomous float, which became the backbone of an international network known as Argo, which the New York Times already described in 2014 as “one of the scientific triumphs of the age.” This Argo network now has 4,000 floats spread around the world, supported by contributions from 30 countries.
What does the past tell us about the future climate ?
Landscapes are the result of current and past climatic conditions. Various places around the globe record information and are called natural archives. Understanding how the climate has varied naturally over thousands and millions of years teaches us how the Earth's climate system works and sheds light on current human-induced changes.
The extent of global warming since 1850 summarized in a single image
Images of climate change created at the University of Reading are now being shared around the world, providing a stark warning of how the planet is heating up. The climate emergency is undeniable as COP 27 opens in Egypt.
Heidi Sevestre, an extreme glaciologist to protect our planet
Heidi Sevestre, French glaciologist and member of the secretariat of AMAP, Arctic Monitoring and Assessment Programme, Working Group of the Arctic Council, devotes her life to science and to raising public awareness of climate issues. She is recognized worldwide for her involvement and her courage in frontline research, leading unprecedented expeditions. His goal today is to make scientific facts more accessible and inspire people to join the fight against the climate crisis.
A new report on the health of the oceans
The Copernicus Marine Environment Monitoring Service (CMEMS) publishes for the European Union, its 6th report on the state of the ocean. Based on a synthesis of data collected on a global scale and on the European regional seas, it draws up an inventory of the health of the oceans of our planet, by scanning three main axes: the physical state of the oceans, its biological state (fauna and flora) and the state of the ice.
Global Ocean Observing System report card released
A new Ocean Observing System Report Card - a high-level annual report providing in-depth insight into the state, capacity and value of the Global Ocean Observing System (GOOS) - just released.
Zooplankton, small in size but large in their role in the ocean
Plankton is essential to our survival. It’s the basis of all oceanic food chains, and essential in particular for the presence of the fish on which we feed.
Corals and their ability to adapt to climate change
Coral reefs are not only one of the most biodiverse ecosystems on our planet, they also weigh heavily economically. With direct income from fishing in their waters, reefs provide a resource and services worth billions of dollars every year.
Scientists build new atlas of ocean’s oxygen-starved waters
These new 3D maps may help researchers track and predict the ocean’s response to climate change.

Mapping of a little-known world: the Southern Ocean reveals its secrets
At the South Pole, the first extremely accurate map of the Southern Ocean sabed has been constructed by German scientists from the Alfred Wegener Institute as part of the “Seabed 2030” project, using surveys carried out by ships around Antarctica.
A huge Atlantic ocean current is slowing down. If it collapses, La Niña could become the norm for Australia
Climate change is slowing down the conveyor belt of ocean currents that brings warm water from the tropics up to the North Atlantic. Our research, published today in Nature Climate Change, looks at the profound consequences to global climate if this Atlantic conveyor collapses entirely.
Nolwenn Lemaitre, Winner of a European Fellowship
Since her thesis was obtained between France and Belgium in 2017, Nolwenn Lemaitre is a post-doctoral fellow in Switzerland where she works on the stable isotopes of trace metals (copper, nickel and zinc) in seawater. She has just obtained a European grant to evaluate the importance of sediments as a source of these trace metals in the ocean.
Sophie Bonnet, French Researcher Awarded an Exceptional European Research Grant
Sophie Bonnet is Director of Research at the Mediterranean Institute of Oceanology (MIO Aix-Marseille University, CNRS, IRD, University of Toulon). She has just won an exceptional European grant for an innovative research project that will examine the biological mechanisms of CO2 sequestration by the ocean, from the study of the cell to the ecosystem as a whole.
Is the Mediterranean Sea running out of steam?
Last June, the 10th oceanographic campaign of the MOOSE network took place in the Mediterranean Sea. For more than a decade, the LOCEAN laboratory, the marine stations of Roscoff, Banyuls, Villefranche-sur-mer of Sorbonne University, the MIO laboratory and CEFREM have been involved in this Mediterranean Ocean Observing System for the Environment financed by CNRS-INSU and the ILICO Research Infrastructure.
The Oceanic Carbon Pump
The ocean is a climate regulator, mainly because it captures ⅓ of the carbon dioxide (CO2) emitted into the atmosphere each year. This phenomenon of "oceanic carbon pump" is due to a double process: a physical process and a biological process.
OneOceanScience: tackling climate change through ocean science
On 25 October, Ifremer, CNRS and IRD (Institut de Recherche pour le Développement) launched a digital world tour of ocean and climate sciences, called OneOceanScience, with the support of Thomas Pesquet but also the European Space Agency (ESA) and the Ocean and Climate Platform.
Participatory science to measure water resources in the Pyrenees
February and April: this winter of 2021 saw new waves of sand from the Sahara covering the snow cover in the Alps and the Pyrenees.
Glacier melt: mapping reveals the acceleration
Glaciers around the world are melting at a record rate due to global warming. Recent studies have shown that global losses have accelerated in recent years, from 227 gigatonnes of ice lost per year between 2000 and 2004 to 298 gigatonnes per year between 2015 and 2019.
The Southern Ocean is warming at depth
An international team of scientists has unveiled analyses of the rise in Antarctic temperatures over the past 25 years. A study that sounds like a wake-up call.
