Whale foraging seascapes: Advective prey aggregation mechanisms predict North Atlantic right whale foraging grounds

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract During foraging activity, baleen whales are generally dependent on the occurrence of dense prey patches. These are largely influenced by the interaction between ocean currents and the vertical distribution of individual prey. Identifying the spatio‐temporal dynamics of the areas where prey form dense aggregations, at submeso scale (~ 10 km ...

Urea provides an important nitrogen source for microbial populations in an ultraoligotrophic sea

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Urea is an organic nitrogen (N) compound directly utilized by both heterotrophic prokaryotes and some photoautotrophs. Reports of either ambient urea concentrations or urea uptake rates from the ultraoligotrophic eastern Mediterranean Sea are lacking. We investigated urea distribution and uptake in the upper water column in the Levantine basin during ...

Species‐specific processing of fluorescent dissolved organic matter by Caribbean sponges

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Coral reefs are biodiverse and productive ecosystems that are found in typically oligotrophic environments. Many studies have attempted to explain this paradox by demonstrating that microbial symbionts expand metabolic capabilities of host animals.

Conditions leading to exceptionally high temperatures in shallow tropical lakes

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Factors leading to exceptionally high temperatures in shallow tropical waters are examined with high‐resolution measurements and application of a 3‐dimensional hydrodynamic model in an Amazon floodplain lake. Highest near‐surface (0.05 m) temperatures in open water ranged from 31.0 to 37.5°C. Within mats of floating plants maximum temperatures

Turnover of microbial cells, endospores, and organic carbon in ocean margin sediment affected by submarine landslides

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract The turnover rate of microbial cells drops steeply by increasing depth in the seabed, in accordance with the decreasing rate of organic matter mineralization. Bacterial endospore formation and germination may take place concurrently, yet their coupling to the mineralization rates during burial is poorly understood.
