Sequestration efficiency in the iron‐limited North Atlantic: Implications for iron supply mode to fertilized blooms [PDF]

open access: yesGeophysical Research Letters, 2014
AbstractEstimates of the amount of carbon sequestered in the ocean interior per unit iron (Fe) supplied, as quantified by the sequestration efficiency (Ceffx), vary widely. Such variability in Ceffx has frequently been attributed to estimate uncertainty rather than intrinsic variability.

Nitrogen and Iron Availability Drive Metabolic Remodeling and Natural Selection of Diverse Phytoplankton during Experimental Upwelling

open access: yesmSystems, 2022
Nearly half of carbon fixation and primary production originates from marine phytoplankton, and much of it occurs in episodic blooms in upwelling regimes.

The ocean response to volcanic iron fertilisation after the eruption of Kasatochi volcano: a regional-scale biogeochemical ocean model study [PDF]

open access: yesBiogeosciences, 2013
In high-nutrient–low-chlorophyll regions, phytoplankton growth is limited by the availability of water-soluble iron. The eruption of Kasatochi volcano in August 2008 led to ash deposition into the iron-limited NE Pacific Ocean. Volcanic ash released iron

Absence of photophysiological response to iron addition in autumn phytoplankton in the Antarctic sea-ice zone [PDF]

open access: yesBiogeosciences, 2023
The high nutrient–low chlorophyll condition of the Southern Ocean is generally thought to be caused by the low bioavailability of micronutrients, particularly iron, which plays an integral role in phytoplankton photosynthesis.

Colony formation in Phaeocystis antarctica: connecting molecular mechanisms with iron biogeochemistry [PDF]

open access: yesBiogeosciences, 2018
Phaeocystis antarctica is an important phytoplankter of the Ross Sea where it dominates the early season bloom after sea ice retreat and is a major contributor to carbon export.

Effect of Iron Availability on the Growth and Microcystin Content of Natural Populations of Microcystis spp. from Reservoirs in Central Argentina: A Microcosm Experiment Approach

open access: yesPhycology, 2023
The eutrophication of aquatic systems is a problem related to the contribution of excess nutrients—phosphorus (P) and nitrogen (N)—to water bodies, which produces an increase in cyanobacterial blooms.

Sedimentary and atmospheric sources of iron around South Georgia, Southern Ocean: a modelling perspective [PDF]

open access: yesBiogeosciences, 2014
In high-nutrient low-chlorophyll waters of the western Atlantic sector of the Southern Ocean, an intense phytoplankton bloom is observed annually north of South Georgia.

Periodic variations of phosphorus migration and transformation in a eutrophic lake of China: The role of algae bloom and collapse

open access: yesFrontiers in Earth Science, 2023
It is a two-way interaction between algae bloom events and nutrient cycles in aquatic environments. In Meiliang bay of Taihu Lake, phosphorus (P) forms in the water, sediment and pore water, and bacterial community structures in the sediment were ...
