Iron (Fe) is the fourth most abundant element in the earth's crust and plays important roles in
both biological and chemical processes. The redox reactivity of various Fe (II) forms has …

The deep sea, the largest ecosystem on Earth and one of the least studied, harbours high
biodiversity and provides a wealth of resources. Although humans have used the oceans for …

Does humanity's future lie in the ocean? As demand for resources continues to grow and

Carbon dioxide capture and geological storage is an enabling technology that will allow the
continued use well into this century of fossil fuels, mainly coal, for power generation and …

The rise of angiosperms during the Cretaceous period is often portrayed as coincident with a
dramatic drop in the diversity and abundance of many seed-free vascular plant lineages …

The availability of iron limits primary productivity and the associated uptake of carbon over
large areas of the ocean. Iron thus plays an important role in the carbon cycle, and changes …

The only major strategy now being seriously considered for biological mitigation of
atmospheric CO 2 relies entirely on terrestrial plants. Photosynthetic microbes were the …

Despite the growing number of in situ iron fertilization experiments, the efficiency of such
fertilization to sequester atmospheric CO2 remains largely unknown. For the first time, a …

The abyssal seafloor covers more than 50% of the Earth and is postulated to be both a
reservoir of biodiversity and a source of important ecosystem services. We show that …
