Microbial nitrogen removal and recycling in the redox transition zone of a meromictic lake and its coupling to sulfur cycling

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Organotrophic denitrification is an important nitrogen (N) removal process in lakes, but alternative N reduction processes such as lithotrophic sulfur (S)‐oxidizing denitrification may be greatly underappreciated. We studied the redox transition zone (RTZ) in the meromictic water column of the North Basin of Lake Lugano (Switzerland) to ...

Tightly coupled carbon, nitrogen, and iron utilization by bacteria in the lower photic zone of the North Pacific Subtropical Gyre

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract The metabolism of heterotrophic bacteria acts as a key control on the turnover of organic matter in the ocean. However, much remains unknown about how nutrient availability, particularly iron concentration, impacts bacterial growth. In the dimly lit waters of the lower photic and upper mesopelagic zones, the attenuation of sinking particulate ...

Imprint of Indian Ocean Dipole on nitrous oxide dynamics

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract The northern Indian Ocean is a hotspot of nitrous oxide (N2O) emissions, with strong seasonal monsoons and interannual Indian Ocean Dipole (IOD) variability. We examine the IOD influence on N2O seasonality using a regional ocean model covering 1981–2020, with a focus on the coastal ocean where ∆pN2O variability is more than threefold greater ...

Nitric oxide supersaturation in the surface waters of the oligotrophic Atlantic Ocean

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Atmospheric nitric oxide (NO) is a pollutant and climate‐relevant trace gas. Dissolved NO accumulates in the surface ocean and therefore the ocean is a natural source of atmospheric NO. It is generally assumed that NO in the surface ocean is produced photochemically from nitrite (NO2−).
