In the oceans, ubiquitous microscopic phototrophs (phytoplankton) account for approximately half the production of organic matter on Earth. Analyses of satellite-derived phytoplankton concentration (available since 1979) have suggested decadal-scale fluctuations linked to climate forcing, but the length of this record is insufficient to resolve longer-term trends. Here we combine available ocean transparency measurements and in situ chlorophyll observations to estimate the time dependence of… Expand

Estimating global chlorophyll changes over the past century
Marine phytoplankton account for approximately half of the production of organic matter on earth, support virtually all marine ecosystems, constrain fisheries yields, and influence climate andExpand
Patterns and ecological implications of historical marine phytoplankton change
There is growing evidence that average global phytoplankton concentrations have been changing over the past century, yet published trajectories of change are highly divergent. Here, we review andExpand
Ecosystem responses in the southern Caribbean Sea to global climate change
TLDR
The results reveal an ecological state change in this planktonic system, including the weakening trend in Trade Winds and dependent local variables, which is largely explained by trends in two climatic indices. Expand
Revaluating ocean warming impacts on global phytoplankton
Global satellite observations document expansions of the low-chlorophyll central ocean gyres and an overall inverse relationship between anomalies in sea surface temperature and phytoplanktonExpand
Regional to global assessments of phytoplankton dynamics from the SeaWiFS mission
Abstract Photosynthetic production of organic matter by microscopic oceanic phytoplankton fuels ocean ecosystems and contributes roughly half of the Earth's net primary production. For 13 years, theExpand
Phytoplankton decline in the eastern North Pacific transition zone associated with atmospheric blocking.
TLDR
It is shown that high-latitude atmospheric blocking events over Alaska are the primary drivers of the recent decline of Chla in the eastern North Pacific transition zone and a mechanism of the top-down teleconnection between the high latitude atmospheric circulation anomalies and the subtropical oceanic primary productivity is proposed.

Spatio-Temporal Dynamics of Phytoplankton Biomass from Ocean Color Remote Sensing and CMIP5 Model Suites
Phytoplankton are the base of the marine food web, and, importantly, drive the biological carbon pump, the combination of photosynthesis, organic carbon sinking and subsurface decomposition ofExpand
Establishing a global climatology of marine phytoplankton phenological characteristics
[1] The timing or phenology of the annual cycle of phytoplankton biomass can be monitored to better understand the underpinnings of the marine ecosystem and assess its response to environmentalExpand
Industrial-era decline in subarctic Atlantic productivity
TLDR
The results suggest that the decline in industrial-era productivity may be evidence of the predicted collapse of northern Atlantic planktonic stocks in response to a weakened Atlantic Meridional Overturning Circulation, and may result in further productivity declines across this globally relevant region. Expand
Long‐term variability of phytoplankton carbon biomass in the Sargasso Sea
TLDR
It is hypothesize that a multiannual shift in the seasonal pattern of mixing may have stimulated and restructured the eukaryote community while suppressing prokaryote populations by increasing photodamage and grazing mortality. Expand

Climate-Driven Basin-Scale Decadal Oscillations of Oceanic Phytoplankton
TLDR
It is shown that multidecadal changes in global phytoplankton abundances are related to basin-scale oscillations of the physical ocean, specifically the Pacific Decadal Oscillation and the Atlantic Multidec NADOscillation. Expand
Climate-driven trends in contemporary ocean productivity
TLDR
Global ocean NPP changes detected from space over the past decade are described, dominated by an initial increase in NPP of 1,930 teragrams of carbon a year, followed by a prolonged decrease averaging 190 Tg C yr-1. Expand
Detection of anthropogenic climate change in satellite records of ocean chlorophyll and productivity
Abstract. Global climate change is predicted to alter the ocean's biological productivity. But how will we recognise the impacts of climate change on ocean productivity? The most comprehensiveExpand

TLDR
Comparison with environmental factors reveals a close link between ocean productivity and global climate trends during this period, with a notable reduction in ocean productivity during the post-1999 period of warming. Expand
Seasonal and ENSO variability in global ocean phytoplankton chlorophyll derived from 4 years of SeaWiFS measurements

Phytoplankton productivity in the North Pacific ocean since 1900 and implications for absorption of anthropogenic CO2

Biogeochemical Controls and Feedbacks on Ocean Primary Production
TLDR
Elucidating the biogeochemical controls and feedbacks on primary production is essential to understanding how oceanic biota responded to and affected natural climatic variability in the geological past, and will respond to anthropogenically influenced changes in coming decades. Expand
Recent Trends in Global Ocean Chlorophyll
