Dynamics and Controls of Methane Oxidation in the Aerobic Waters of Eastern China Marginal Seas

Liu, Qiao; Du, Guanxiang; Li, Xiao‐Jun; Liu, Jiarui; Meng, Ni;

2024 Journal of Geophysical Research Oceans

doi:10.1029/2023jc020280

Aerobic methane oxidation (MOx) mediated by methanotrophs is a crucial mechanism in controlling methane emissions from the surface ocean to the atmosphere. Coastal waters dominate global oceanic methane emissions, but the dynamics, controls and roles of MOx remain largely unconstrained in the...

Signature of Mesoscale Eddies on Air‐Sea Heat Fluxes in the North Indian Ocean

Chen, Yanxu; Yu, Lisan

2024 Journal of Geophysical Research Oceans

doi:10.1029/2023jc019878

Using a combination of 20‐year (1999–2018) remotely‐sensed air‐sea heat flux products and altimeter‐based eddy atlas, we investigate the signature of mesoscale eddies on sea surface temperature (SST) and air‐sea turbulent latent and sensible fluxes, or simply, turbulent heat fluxes (THFs), in the...

Variability of Fine‐Scale Chlorophyll Fronts in the Tīkapa Moana Te Moananui ā Toi Hauraki Gulf, Aotearoa New Zealand

Lhériau‐Nice, Alexandre; Della Penna, Alice

2024 Journal of Geophysical Research Oceans

doi:10.1029/2023jc020391

Aotearoa New Zealand's marine environment is heavily impacted by El Niño Southern Oscillation (ENSO). Little is known about the effect of ENSO on oceanographic properties in the area or their consequences on the distribution of marine organisms. Here we characterize the spatio‐temporal...

Physical and Biogeochemical Properties of California Current Upwelled Source Waters

Fiechter, Jerome; Moore, Andrew M.

2024 Journal of Geophysical Research Oceans

doi:10.1029/2023jc020164

Coastal upwelling variability in the California Current region, one of the four main eastern boundary current upwelling systems, is controlled by processes acting over a wide range of spatial and temporal scales. While the ensuing ecosystem response depends strongly on upwelled water properties,...

The Ocean's Meridional Oxygen Transport

Portela, Esther; Kolodziejczyk, Nicolas; Gorgues, Thomas; Zika, Jan; Perruche, Coralie;

2024 Journal of Geophysical Research Oceans

doi:10.1029/2023jc020259

Quantification of oxygen uptake at the ocean surface and its surface‐to‐interior pathways is crucial for understanding oxygen concentration change in a warming ocean. We investigate the mean meridional global oxygen transport between 1950 and 2009 using coupled physical‐biogeochemical model...

Modeled Coastal‐Ocean Pathways of Land‐Sourced Contaminants in the Aftermath of Hurricane Florence

Moulton, Melissa; Zambon, Joseph B.; Xue, Z. George; Warner, John C.; Bao, Daoyang;

2024 Journal of Geophysical Research Oceans

doi:10.1029/2023jc019685

Extreme precipitation during Hurricane Florence, which made landfall in North Carolina in September 2018, led to breaches of hog waste lagoons, coal ash pits, and wastewater facilities. In the weeks following the storm, freshwater discharge carried pollutants, sediment, organic matter, and debris...

The Role of Rapid Changes in Weather on Phytoplankton Spring Bloom Dynamics From Mid‐Norway Using Multiple Observational Platforms

Fragoso, G. M.; Dallolio, A.; Grant, S.; Garrett, J. L.; Ellingsen, I.;

2024 Journal of Geophysical Research Oceans

doi:10.1029/2023jc020415

The spring phytoplankton bloom plays a major role in pelagic ecosystems; however, its dynamics are not well understood due to insufficient, highly resolved observational data. Here we investigate the start, peak, and decline of a 2‐week phytoplankton spring bloom in Frohavet located in a...

Role of Intersecting Equatorial and Coastal Waveguides Near Sri Lanka on Intraseasonal Sea Level Variability Along the West Coast of India

Suresh, Iyyappan; Vialard, Jérôme; Izumo, Takeshi; Lengaigne, Matthieu

2024 Journal of Geophysical Research Oceans

doi:10.1029/2023jc020198

The sea level variations along the west coast of India (WCI) significantly affect the ecosystems and fisheries, because of their tight coupling with the oxycline depths in this region, which hosts the world's largest natural hypoxic system. Here, we investigate the main causes of the WCI sea...

Laboratory Investigation of Energy Dissipation and Turbulent Mixing During Internal Solitary Wave Breaking on the Rough Shelf Slope

Yuan, Yeping; Luo, Yuanye; Wang, Yixin; Lin, Ying‐Tien; Liu, Qian;

2024 Journal of Geophysical Research Oceans

doi:10.1029/2023jc020440

When internal solitary waves (ISW) propagate to the continental shelf, they typically runup and break on the forereef. This process might lead to periodic temperature drops at the reef slope, which has potential to protect coral reefs from bleaching threats. A series of laboratory experiments...

Surface Heat Fluxes Drive a Two‐Phase Response in Southern Ocean Mode Water Stratification

Pimm, Ciara; Williams, Richard G.; Jones, Dani; Meijers, Andrew J. S.

2024 Journal of Geophysical Research Oceans

doi:10.1029/2023jc020795

Subantarctic mode waters have low stratification and are formed through subduction from thick winter mixed layers in the Southern Ocean. To investigate how surface forcing affects the stratification in mode water formation regions in the Southern Ocean, a set of adjoint sensitivity experiments...
