On the Efficacy of Ocean Formation with a Primordial Hydrogen Atmosphere
It has been suggested that Earth's present water budget formed from oxidation reactions between its initial hydrogen-rich primordial atmosphere and its magma ocean. Here we examine this hypothesis by building a comprehensive atmosphere-magma ocean model. We find that water formation is unlikely for two reasons. First, any water formed from oxidation reactions in the magma ocean would quickly outgass because of the water-poor atmosphere above. Second, the top boundary layer of the magma ocean be…

Does rainfall create buoyant forcing at the ocean surface?
Rain affects the buoyancy of the upper ocean in two ways: The freshwater flux in rain makes the water fresher and lighter, stabilizing the ocean (a negative buoyancy flux). The convective systems that produce rain are often accompanied by cold, dry air, often called 'cold pools', and reduced short-wave radiation, which makes the water colder and heavier, destabilizing the ocean (a positive buoyancy flux). We estimate net buoyancy fluxes using in situ measurements from twenty-two moored buoys in…

Rapid topographic scatter of near-inertial waves generated by storms
Internal waves propagate on the ocean's stratification, carrying energy and redistributing momentum through the ocean. When internal waves break, they contribute to diapycnal mixing in the ocean interior, but this breaking behaviour depends upon the scale of the waves. Low-mode internal waves have larger horizontal and vertical scales, and thus break less readily than higher-mode waves. The scattering of internal waves by topography is an important mechanism in transferring internal wave energy…

A validated coupled three-dimensional hydrodynamic and spectral wind-wave model for the western north Atlantic Ocean
Wind-wave and ocean current interactions affect critical coastal and oceanic processes, yet modeling these interactions presents significant challenges. The western North Atlantic Ocean provides an ideal test environment for coupled hydrodynamics and wind wave models, thanks to its energetic surface currents such as the Gulf Stream. This study evaluates a high-resolution coupled SCHISM WWM III model, utilizing NOAA's 'STOFS-3D-Atlantic' computational mesh, while incorporating three-dimensional …

New simulations show how much colder European winters would get if AMOC collapses
A pair of meteorologists in the Netherlands has used new simulations to show just how cold many of Europe's cities could get if the Atlantic Meridional Overturning Circulation (AMOC) were to collapse due to global warming. In their study, published in the journal Geophysical Research Letters, René van Westen and Michiel Baatsen developed a climate model based on a range of ocean temperature changes that could arise due to global warming.

Unravelling how winds and surface heat fluxes control the Atlantic Oceans meridional heat transport
The North Atlantic Ocean circulation, fuelled by winds and surface buoyancy fluxes, carries 1.25 PettaWatts of heat poleward in the subtropics, and helps in regulating global weather and climate patterns. Here, we assess the relative impacts of changes in winds and surface heat fluxes on the Atlantic Ocean circulation and heat transport on short timescales (<10 years) and long timescales (>50 years) using ocean simulations. We decompose the circulation and heat transport into warm and cold cell…

David Attenborough's 'Ocean' exposes the unseen destruction of the seas
The new film “Ocean With David Attenborough” is both a breathtaking celebration of marine life and a sobering exposé of the industrial forces pushing the ocean toward collapse. With never-before-seen footage from mass coral bleaching to the violent destruction of bottom trawling, it reveals the hidden toll of human activity beneath the waves. But it’s also a story of hope that spotlights thriving marine reserves and the power of protection. Timed to World Oceans Day and the U.N. Ocean Co…

Samoa’s new marine spatial plan protects 30% of the country’s ocean
Samoa, an archipelagic country composed of nine islands in the South Pacific Ocean, is on the frontline of climate change. Rising sea levels, ocean warming and acidification all pose significant threats to the country’s coastal communities. To help protect its future, the Samoan government announced June 3 that it has enacted a law establishing a […]

Gulf Stream drives Kuroshio behind the recent abnormal ocean warming
Recent unprecedented ocean warming has produced coherent sea surface temperature (SST) anomalies across the Northern Hemisphere extratropics. Despite extensive research on inter-basin interactions, the causal mechanisms linking North Pacific and North Atlantic variability remain poorly understood. Here we show that internal SST variability in the Gulf Stream region accounts for 16% of internal SST variability in the Kuroshio region in climate model simulations, while no significant reverse infl…

Waves in ice
Ocean surface waves can propagate long distances through regions containing floating ice covers. The impacts ocean waves have on the ice covers are of interest in the climate change era, as the polar regions experience pressure from rising temperatures. This chapter provides a review of observations and theoretical models for ocean wave propagation through the marginal ice zone, landfast ice and ice shelves. It traces the historical evolution of the field, from seminal work in the 1970s-80s up …

Only a tiny % of the deep seafloor has ever been visually observed: Study
For national and international policymakers, decisions on how to regulate — and whether to allow — exploitative human activities such as deep-sea mining require good information. A new study suggests that when it comes to the ocean floor, they may not have it. Only 0.001% of the deep seafloor has ever been captured by photo […]

Deep Learning Weather Models for Subregional Ocean Forecasting: A Case Study on the Canary Current Upwelling System
Oceanographic forecasting impacts various sectors of society by supporting environmental conservation and economic activities. Based on global circulation models, traditional forecasting methods are computationally expensive and slow, limiting their ability to provide rapid forecasts. Recent advances in deep learning offer faster and more accurate predictions, although these data-driven models are often trained with global data from numerical simulations, which may not reflect reality. The emer…

Asymmetric response of the North Atlantic gyres to the North Atlantic Oscillation
The North Atlantic Oscillation (NAO) is a leading mode of atmospheric variability, affecting the North Atlantic Ocean on sub-seasonal to multi-decadal timescales. The NAO changes the atmospheric forcing at the ocean's surface, including winds and surface buoyancy fluxes, both of which are known to impact large-scale gyre circulation. However, the relative role of other physical processes (such as mesoscale eddies and topography) in influencing gyre circulation under NAO variability is not fully…

Tuna fishing devices drift through a third of oceans, harming corals, coasts: Study
A recent study reveals that drifting fish aggregating devices (dFADs), widely used in tuna fishing, have spread to more than a third of the world’s oceans.  These devices harm ocean life and coastal communities, but weak rules and lack of accountability make it hard to manage them properly, some conservationists say. The study, published in […]
