Blooms of filamentous cyanobacteria reduce zooplankton quality and pelagic food web efficiency

open access: yesLimnology and Oceanography, EarlyView.
Abstract Cyanobacterial blooms in marine and freshwater ecosystems have increased in magnitude, frequency, and distribution worldwide during recent decades. Filamentous cyanobacteria are of unsuitable size for mesozooplankton feeding and of poorer nutritional quality than other phytoplankton taxa. The production and quality of higher trophic levels are

A low oxygen threshold for physiological responses and trace metal quotas of Prochlorococcus and Synechococcus

open access: yesLimnology and Oceanography, EarlyView.
Abstract Continued human activity is expected to accelerate ocean deoxygenation, leading to the expansion and shallowing of oxygen‐deficient zones (ODZs). This decline in oxygen may impact both phytoplankton growth and trace metal uptake. We conducted culture experiments with Prochlorococcus MIT9313 and Synechococcus XM‐24, two numerically dominant ...

Timing of calcification and environmental variability determine pH proxy fidelity in coastal calcifying macroalgae

open access: yesLimnology and Oceanography, EarlyView.
Abstract Long‐lived calcifying marine biota are increasingly used as paleo‐archives for reconstructing ocean pH. They enable exploration of the rate and magnitude of ocean acidification in shallow‐water ecosystems serving as proxies for environmental pH reconstruction.

Predictive links between microbial communities and biological oxygen utilization in the Arctic Ocean

open access: yesLimnology and Oceanography, EarlyView.
Abstract Microbial metabolism influences rates of net community production (NCP), exerting a direct biological control on marine oxygen and carbon fluxes. In the Arctic, it is increasingly important to understand and quantify this process, as ecological and oceanographic conditions shift due to changing climate.

Radium isotopes quantify vertical mixing and reveal large benthic silicate fluxes in anoxic deep waters

open access: yesLimnology and Oceanography, EarlyView.
Abstract Benthic fluxes are important sources of nutrients and dissolved carbon to the water column. Yet, most approaches for quantifying benthic fluxes are labor intensive and cover relatively small areas of the ocean. Here, we use 224Ra to quantify ecosystem‐scale vertical mixing across a largely hypoxic deep water column in the Baltic Sea and ...
