Compound-specific isotope analysis encompasses a variety of methods for examining the
naturally occurring isotope ratios of individual organic molecules. In marine environments …

The water column of the deep ocean is dark, cold, low in food, and under crushing
pressures, yet it is full of diverse life. Due to its enormous volume, this mesopelagic zone is …

Suspended particles are major organic carbon substrates for heterotrophic microorganisms
in the mesopelagic ocean (100–1000 m). Nonetheless, communities associated with these …

The origin of methylmercury in pelagic fish remains unclear, with many unanswered
questions regarding the production and degradation of this neurotoxin in the water column …

A quantitative understanding of the mesopelagic zooplankton food web is key to
development of accurate carbon budgets and geochemical models in marine systems. Here …

Particulate organic matter settling out of the euphotic zone is a major sink for atmospheric
carbon dioxide and serves as a primary food source to mesopelagic food webs. Degradation …

The oceans are an important global reservoir for mercury (Hg), and marine fish consumption
is the dominant human exposure pathway for its toxic methylated form. A more thorough …

Bacteria are an important component of the aquatic ecosystem playing a key role in the
transformation and mineralisation of allochthonous organic matter, nutrients and pollutants …

Coastal upwelling supplies nutrients supporting primary production while also adding the
toxic trace metal mercury (Hg) to the mixed layer of the ocean. This could be a concern for …

A size‐selective loss of smaller microplastics (< 1 mm) from surface pelagic waters has been
reported, yet few surveys have studied biological ingestion by deep‐pelagic organisms as a …
