Anthropogenic iron impact on the surface productivity in the Pacific Transition Zone
Hawco and colleagues investigated the influence of industrial emissions on oceanic iron supply and its ecological consequences in the North Pacific.
Limitation
Iron limitation also affects the twilight zone
Li and co-workers established the distribution and uptake of siderophores along the Pacific meridional section (GP15 GEOTRACES cruise)…
Widespread nutrient co-limitation discovered on GEOTRACES cruise
Browning and co-workers (2017, see reference below) find that multiple nutrients must be supplied to stimulate phytoplankton growth on the southeast Atlantic GEOTRACES GA08 cruise. The paper has been published […]
Do you know that coastal phytoplankton is able to adapt to iron limitation?
Oceanographers have long understood that phytoplankton in the open ocean tend to have lower iron (Fe) requirements and/or more strategies for obtaining Fe from the environment. Adding a new twist […]
Seasonal iron supply in the Southern Ocean is dominated by winter mixing
An international team of researchers analysed the available dissolved iron data taken from all previous studies of the Southern Ocean, together with satellite images taken of the area, to quantify […]
