Saharan dust deposition may affect phytoplankton growth in the mediterranean sea at ecological time scales [PDF]

open access: yes, 2014
The surface waters of the Mediterranean Sea are extremely poor in the nutrients necessary for plankton growth. At the same time, the Mediterranean Sea borders with the largest and most active desert areas in the world and the atmosphere over the basin is

Iron, silicate, and light co-limitation of three Southern Ocean diatom species [PDF]

open access: yes, 2008
The effect of combined iron, silicate, and light co-limitation was investigated in the three diatom species Actinocyclus sp. Ehrenberg, Chaetoceros dichaeta Ehrenberg, and Chaetoceros debilis Cleve, isolated from the Southern Ocean (SO).

Size Class Dependent Relationships between Temperature and Phytoplankton Photosynthesis-Irradiance Parameters in the Atlantic Ocean

open access: yesFrontiers in Marine Science, 2018
Over the past decade, a number of methods have been developed to estimate size-class primary production from either in situ phytoplankton pigment data or remotely-sensed data.

Production of extracellular reactive oxygen species by phytoplankton: past and future directions

open access: yesJournal of Plankton Research, 2018
In aquatic environments, phytoplankton represent a major source of reactive oxygen species (ROS) such as superoxide and hydrogen peroxide. Many phytoplankton taxa also produce extracellular ROS under optimal growth conditions in culture.

Exploring the link between micro-nutrients and phytoplankton in the Southern Ocean during the 2007 austral summer

open access: yesFrontiers in Microbiology, 2012
Bottle assays and large-scale fertilisation experiments have demonstrated that, in the Southern Ocean, iron often controls the biomass and the biodiversity of primary producers.

Primary production of phytoplankton in the three types of Amazonian waters. V. Some investigations on the phytoplankton and its primary productivity in the clear water of the lower Rio Tapajós (Pará, Brazil)

open access: yes, 1982
Four limnological investigations were conducted in different seasons of the years 1968 and 1969 at the lower reaches of the Rio Tapajóz. The physical and chemical parameters generally correspond with earlier findings of other authors. Midriver areas show

Cyclonic cold-core eddy in the eastern North Atlantic. II. Nutients, phytoplankton and bacteriaplankton [PDF]

open access: yes, 1987
A cyclonic cold-core eddy in the Northeast Atlantic of about 100 km in diameter at the sea surface was investigated in May 1985, approximately 3 wk after it had separated from the Polar Front.
