Emergent patterns of patchiness differ between physical and planktonic properties in the ocean Open
While a rich history of patchiness research has explored spatial structure in the ocean, there is no consensus over the controls on biological patchiness and how physical-ecological-biogeochemical processes and patchiness relate. The preva…

Ubiquity of inverted ’gelatinous’ ecosystem pyramids in the global ocean Open
Summary paragraph Plankton are essential in marine ecosystems. However, our knowledge of overall community structure is sparse due to inconsistent sampling across their very large organismal size range. Here we use diverse imaging methods …

Jewels of Scientific Illustration from Oceanographic Reports in the Library of the Institute de la Mer de Villefranche Open
The discipline of Oceanography might seem unlikely to harbor artistic work. However, the study of the ocean includes the study of marine organisms. Depictions of marine organisms appear in many reports of oceanographic expeditions, and som…

New observations of Papulifères, putative ciliate cysts, from the plankton of the Chukchi Sea (Western Arctic Ocean) in August of 2023 Open
We recently documented the existence of 26 different forms of Papulifères, presumptive ciliate cysts, from plankton net tow material of the Chukchi Sea gathered in 2015, 2021, and 2022. The forms appeared to be rare, found in only 7 of the…

On Papulifères, putative ciliate cysts of diverse morphologies, with new observations from the plankton of the Chukchi Sea (Arctic Ocean) Open
In the early 20th century, Alphonse Meunier described "Papulifères" as a group of enigmatic forms of unknown taxonomic affinity characterized by possessing a hyaline pimple, a "papula". In the early 1980's Papulifères were equated with cys…
