In the study of ocean currents, scientists typically deploy GPS-tagged buoys and measure their velocities to reconstruct the underlying currents that transport them. This collected data also aids in detecting regions where water ascends from the depths or descends beneath the surface, phenomena referred to as “divergences.” Through precise current predictions and the identification of …

Christopher Pearce, Principal Marine Geoscientist at the National Oceanography Centre, delves into the possibilities and obstacles of employing ocean-based carbon dioxide removal techniques as a means to curtail greenhouse gas emissions. The widespread adoption of net zero targets and emission reduction strategies has become a common goal in our quest to mitigate future global warming. …

As climate change continues to cause marine heatwaves, coral reefs face unprecedented threats. However, researchers have discovered a phenomenon that holds promise for coral reef managers in their efforts to mitigate these challenges and plan for the future. The tropical Pacific experiences periodic climate shifts known as El Niño, characterized by notable alterations in winds, …

The mechanism involves the warming of the ocean subsurface, leading to decreased surface salinity caused by the release of massive iceberg armadas from glaciers. The Atlantic meridional overturning circulation (AMOC) is a crucial ocean current system responsible for regulating Earth’s climate by transporting warm and cold water across the globe. In the past, this system …

A recent study published in the journal Nature Communications by British climatologists at the University of Exeter has revealed that the population of the “twilight zone” in the ocean may decrease by 20-40% in the near future, as a result of the increase in marine microbial activity. The layer of the World Ocean known as …

Philippe Cury, a marine ecologist, presents a bleak depiction of the ocean’s condition, describing a scenario where the fish are becoming smaller and smaller, ecosystems are disrupted, and carbon sinks are devastated. What is the condition of marine biodiversity? The current state of marine biodiversity is dire, with 43% of fishery resources being overexploited today …

Real-time storm data, including that of Category 4 Hurricane Fiona, approaching eastern Canada, is being collected using instruments such as Saildrones. Last fall, OAA oceanographer Greg Foltz closely monitored Hurricane Sam’s tracking and intensity, analyzing satellite images and data to estimate its trajectory over the next 12-24 hours. He needed to position an uncrewed surface …

Statistically, as of today, eight billion people live in the world. An end to population growth is not in sight. What does this mean for climate protection? Eight billion – so many people have never lived on our planet before. So what does climate protection have to look like that keeps our ecological footprint as …

2022 is a year of climate records – unfortunately in a negative sense. The Intergovernmental Panel on Climate Change finds that most nations are doing too little to protect the climate. At the same time, the consequences of climate change are becoming increasingly noticeable around the globe. Expensive natural disasters The costs of natural catastrophes …

The authorities of Dagestan report that 2,500 dead seals (these animals are also known as the Caspian seal) have been found on the coast of the Caspian Sea in recent days. The exact causes of the deaths of the seals are still being established, but the regional Ministry of Nature suggests that they are related …
