Abstract Southern Ocean phytoplankton have unique traits that allow them to survive extreme environmental conditions of low iron, light, and temperature. These traits are not well represented in Earth System Models and may lead to misrepresentation of the bloom seasonal cycle in this critical oceanic region.

In this study, we carried out dilution experiments at the surface and in the mesopelagic and bathypelagic layers at 15 sites in the Mediterranean Sea that covered a wide range of trophic conditions.

Seasonal and spatial patterns of picophytoplankton growth, grazing and distribution in the East China Sea [PDF]
Dynamics of picophytoplankton population distribution in the East China Sea (ECS), a marginal sea in the western North Pacific Ocean, were studied during two cruises in August 2009 (summer) and January 2010 (winter).

Microzooplankton grazing in the Eastern Bering Sea in summer
Dilution experiments to estimate microzooplankton grazing on phytoplankton were conducted during the summers of 2008, 2009, and 2010 in the Eastern Bering Sea as part of the BEST-BSIERP integrated ecosystem project. All three summers followed cold springs in the Bering Sea.

Abstract Climate change is increasing the frequency, intensity, and stochasticity of extreme weather events such as heavy rainfall, storm‐induced mixing, or prolonged drought periods. This results in more variable regimes of dissolved nutrients and carbon in lakes and induces temporal fluctuations in the resource availability for plankton communities ...

Microzooplankton Grazing and Productivity in the Central and Southern Sector of the Indian River Lagoon, Florida [PDF]
Microzooplankton grazing was measured with the dilution method in the central and southern sectors of the Indian River Lagoon during summer 2006 and 2007. Microzooplankton actively grazed phytoplankton during all experiments. Grazing rates averaged (± SD)

Modelling Mesocosm Experiments [PDF]
In this report, an integrated model including fate of and effects of contaminants on an ecological model is presented. The aim is to simulate the dynamic behaviour of the mesocosm experiments carried out at NERI (see D431-D433) to elucidate the combined ...

Phytoplankton Growth and Microzooplankton Grazing in the Subtropical Northeast Atlantic
Dilution experiments were performed to estimate phytoplankton growth and microzooplankton grazing rates during two Lagrangian surveys in inner and eastern locations of the Eastern North Atlantic Subtropical Gyre province (NAST-E). Our design included two phytoplankton size fractions (0.2-5 µm and >5 µm) and five depths, allowing us to characterize ...

Dilution effects on microzooplankton in dilution grazing experiments [PDF]
In dilution experiments, filtered seawater is used to create a gradient of grazing pressure on phytoplankton. Microzooplankton grazing is estimated by examining phytoplankton growth within the gradient. However, the dilution series also represents a resource gradient for microzooplankton. Here we report the effects of dilution on grazers. In 2 standard

Abstract Eutrophication in the Baltic Sea has caused an imbalance in the inorganic nitrogen (N) to phosphorus (P) ratio, leaving excess phosphate (PO4) after the phytoplankton spring bloom that terminates after N depletion. Using monitoring data, we demonstrated that the PO4 concentration has continued to increase in the outermost Gulf of Finland ...
