Large deep-sea zooplankton biomass mirrors primary production in the global ocean
Zooplankton biomass in the dark ocean is thought to be low and weakly coupled to epipelagic primary production, but recent evidence suggests otherwise.

New information from fish diets on the importance of glassy flying squid (Hyaloteuthis pelagica) (Teuthoidea: Ommastrephidae) in the epipelagic cephalopod community of the tropical Atlantic Ocean [PDF]
Squids of the family Ommastrephidae are a vital part of marine food webs and support major fisheries around the world. They are widely distributed in the open ocean, where they are among the most abundant in number and biomass of nektonic epipelagic ...

Stable vectors in Moy-Prasad filtrations
Let k be a finite extension of Q_p, let G be an absolutely simple split reductive group over k, and let K be a maximal unramified extension of k. To each point in the Bruhat-Tits building of G_K, Moy and Prasad have attached a filtration of G(K) by ...

Abstract Variability in nutrient supply is a defining feature of oligotrophic oceans, yet how nutrient fluxes shape consumer physiology and population structure remains poorly resolved. Here, we examine how diazotrophic nitrogen fixation relates to stoichiometric metabolism and genetic structure in the widespread pelagic copepod Pleuromamma xiphias ...

Distribution of Virus-Infected Bacteria in the Western Equatorial Pacific. [PDF]
v. ill. 23 cm.QuarterlyViruses are generally considered an important agent of bacterial loss in diverse marine environments. However, the impact of viruses on bacteria is unknown in the western equatorial Pacific, where surface waters are warm and ...

The IceShark, an effective method for sampling plankton under sea ice
Abstract Seasonal sea ice plays a crucial role in shaping coastal ecosystem dynamics throughout the circumpolar region. Of particular interest to oceanographers is the ice‐ocean interface which functions as a multidimensional habitat, supporting both sympagic algae and pelagic phytoplankton in the under‐ice surface waters.

Potential and expression of carbohydrate utilization by marine fungi in the global ocean
Background Most of the research on the cycling of carbon in the open-ocean has focused on heterotrophic prokaryotes and eukaryotic phytoplankton, but the role of pelagic fungi remains largely enigmatic.

Upper Ocean Cycling of Iron South of the Polar Front: Biological Patterns and Processes
Abstract Samples from the upper 300 m along the 52°S band, south of the Antarctic Polar Front in the Atlantic sector of the Southern Ocean, including a 3‐week monitoring of a persistent bloom, were analyzed to advance our understanding of iron cycling and supply to recurrent phytoplankton blooms.
