Ask not what your journal can do for you—ask what you can do for your journal 🌊

JGR:Oceans is now looking for new Editors and Associate Editors, if you're interested get in touch. We don't bite! 😀

Ocean waves around the world often come from different places and weather systems at the same time, creating complex sea conditions. Portilla-Yandún & Bidlot suggest a new way to analyze ocean waves by grouping them into “wave families” 🌊

Stratification strongly influences the Arctic Ocean's response to climate change. Challet et al., use 35 years of observations to constrain short-term and long-term drives of shifting stratification in the Arctic 🌊

Warm water intrusions onto Antarctica's continental shelves drive ice melt and destabilize glaciers. However, uncertainties remain about mechanisms driving these intrusions. Ribeiro et al., use a high-resolution model to show wind is a key driver 🌊

The RAPID-MOCHA-WBTS array has been designed to observe and understand changes in the Atlantic Meridional Overturning Circulation. Petit et al., assess if a smaller, cheaper array could be designed without losing accuracy in the AMOC estimate 🌊

When marine temperatures go up, there’s less carbon going down.
Marine Heat Waves Slow the Ocean’s Carbon Flow - Eos
When plankton find themselves in hot water, organic matters stalls at the surface and disrupts transport of carbon to the deep ocean.

The subpolar North Atlantic is one region where the deep ocean is in direct contact with the atmosphere, making it a key site for ocean ventilation. Koelling et al., use a new data product to study North Atlantic ventilation in unprecedented detail 🌊

C-CoMP focuses on microbes & chemicals, so it is easy for us to forget how vast our ocean is 🌊. Being at sea 🚢 is the loveliest reminder - there’s nothing as wondrous or humbling as floating in endless cerulean blue while receiving rare visits from animals🐦!

Is there a “methane bomb” lying in Arctic permafrost? New research suggests the answer is complicated—warming Arctic soils might help or hurt the climate, depending on other factors like hydrology. eos.org/articles/in-...
In Arctic Soils, Methane-Eating Microbes Just Might Win Out over Methane Makers - Eos
Methanotrophs, including those that capture methane from the air, seem to outcompete methanogens in dry environments, a new study shows.

Coastal dynamics are complex, influenced by freshwater, alongshore flows, offshore intrusions, and different mixing processes. Veatch et al., use a Lagrangian diagnostic tool to characterize patterns of transport in the coastal Mid-Atlantic Bight 🌊

The Bering Sea is a productive subarctic ecosystem with some of the most valuable fisheries in the US, but is undergoing drastic changes as the climate warms. Cynar et al., use sensors to produce a high-resolution time series of primary production 🌊

Cold seeps are a major source of methane to the ocean. Wang et al., explore how iron minerals respond to cold seep evolution and suggest iron minerals may serve as proxies for reconstructing seep evolution history 🌊

Subglacial freshwater from beneath the Antarctic Ice Sheet flows into the ocean under ice shelves. Vaňková et al., probe how this affects ice melt, finding that discharge impacts melt rates primarily via continental shelf temperature modification 🐧 🌊

Episodic events, such as swirling water from eddies, fronts, and strong winds, can transport large amounts of organic carbon into deeper waters on short timescales. Kheireddine et al., deploy gliders to study these events in the Red Sea 🌊
