Open AccessA Lagrangian model for drifting ecosystems reveals heterogeneity-driven enhancement of marine plankton blooms
Marine plankton play a crucial role in carbon storage, global climate, and ecosystem function. Planktonic ecosystems are embedded in patches of water that are continuously moving, stretching, and diluting. The...

Open AccessGlobal climate-change trends detected in indicators of ocean ecology
Strong natural variability has been thought to mask possible climate-change-driven trends in phytoplankton populations from Earth-observing satellites. More than 30 years of continuous data were thought to be ...

Open AccessGlobal patterns in marine organic matter stoichiometry driven by phytoplankton ecophysiology
The proportion of major elements in marine organic matter links cellular processes to global nutrient, oxygen and carbon cycles. Differences in the C:N:P ratios of organic matter have been observed between oce...

Open AccessFuture phytoplankton diversity in a changing climate
The future response of marine ecosystem diversity to continued anthropogenic forcing is poorly constrained. Phytoplankton are a diverse set of organisms that form the base of the marine ecosystem. Currently, o...

Open AccessGlobal health effects of future atmospheric mercury emissions
Mercury is a potent neurotoxin that poses health risks to the global population. Anthropogenic mercury emissions to the atmosphere are projected to decrease in the future due to enhanced policy efforts such as...

Open AccessOcean colour signature of climate change
Monitoring changes in marine phytoplankton is important as they form the foundation of the marine food web and are crucial in the carbon cycle. Often Chlorophyll-a (Chl-a) is used to track changes in phytoplan...

Open AccessEcological control of nitrite in the upper ocean
Microorganisms oxidize organic nitrogen to nitrate in a series of steps. Nitrite, an intermediate product, accumulates at the base of the sunlit layer in the subtropical ocean, forming a primary nitrite maximu...

Open AccessToward a consistent modeling framework to assess multi-sectoral climate impacts
Efforts to estimate the physical and economic impacts of future climate change face substantial challenges. To enrich the currently popular approaches to impact analysis—which involve evaluation of a damage fu...

Influence of diatom diversity on the ocean biological carbon pump
Diatoms sustain the marine food web and contribute to the export of carbon from the surface ocean to depth. They account for about 40% of marine primary productivity and particulate carbon exported to depth as...

Impact of ocean acidification on the structure of future phytoplankton communities
The responses of phytoplankton growth rates to ocean acidification were investigated in a meta-analysis. A marine ecosystem model calibrated with the results indicates that these different responses will resul...

Valuing climate impacts in integrated assessment models: the MIT IGSM
We discuss a strategy for investigating the impacts of climate change on Earth’s physical, biological and human resources and links to their socio-economic consequences. As examples, we consider effects on agr...
