Polluting shipwrecks a ticking timebombs at the bottom of our oceans
As rusting war-era ships decay on the seafloor, their toxic cargoes pose an urgent but often overlooked environmental risk.

Marine robots are exploring the ocean's role in climate control
A robotic fleet in the Labrador Sea is tracking sinking carbon to reveal how the deep ocean helps regulate Earth’s climate.

Nations urged to make UN summit a 'turning point' for oceans #environment

Nations urged to make UN summit a 'turning point' for oceans
Nations will be under pressure to deliver more than just rhetoric at a UN oceans summit in France next week, including much-needed funds to better protect the world's overexploited and polluted seas.

Staff of the Federal Emergency Management Agency were left baffled on Monday after the head of the US disaster agency said during a briefing that he had not been aware the country has a hurricane season, according to four sources familiar with the situation.
The US hurricane season officially began on Sunday and lasts through November.
The National Oceanic and Atmospheric Administration forecast last week that this year’s season is expected to bring as many as 10 hurricanes.

The Density Profile of Dynamical Halos
Among the most fundamental properties of a dark matter halo is its density profile. Motivated by the recent proposal by García et al. [R. García et. al., MNRAS 521, 2464 (2023)] to define a dynamical halo as the collection of orbiting particles in a gravitationally bound structure, we characterize the mean and scatter of the orbiting profile of dynamical halos as a function of their orbiting mass. We demonstrate that the orbiting profile of individual halos at fixed mass depends on a single d…

Sub-Neptunes Are Drier Than They Seem: Rethinking the Origins of Water-Rich Worlds
Recent claims of biosignature gases in sub-Neptune atmospheres have renewed interest in water-rich sub-Neptunes with surface oceans, often referred to as Hycean planets. These planets are hypothesized to form beyond the snow line, accreting large amounts of H$_2$O >10 wt%) before migrating inward. However, current interior models often neglect chemical equilibration between primordial atmospheres and molten interiors. Here, we compute global chemical equilibrium states for a synthetic populatio…

Helical flows spontaneously generated by salt fingers
We study the dynamics of salt fingers in the regime of slow salinity diffusion (small inverse Lewis number) and strong stratification (large density ratio), focusing on regimes relevant to Earth's oceans. Using three-dimensional direct numerical simulations in periodic domains, we show that salt fingers exhibit rich, multiscale dynamics in this regime, with vertically elongated fingers that are twisted into helical shapes at large scales by mean flows and disrupted at small scales by isotropic …

As ocean acidification ramps up, experts call for speedy ocean protection
Ocean health is moving into a danger zone, with rampant human-caused carbon dioxide emissions having already pushed ocean acidification levels beyond safe limits in large swaths of the marine environment, according to a recent study. The new findings underline the urgent need to ramp up protection of the world’s oceans, while simultaneously slashing CO2 emissions, […]
