  • Behrenfeld, Michael J. (Ecological Society of America, 2010-04)
    The Critical Depth Hypothesis formalized by Sverdrup in 1953 posits that vernal phytoplankton blooms occur when surface mixing shoals to a depth shallower than a critical depth horizon defining the point where phytop ...
  • Behrenfeld, Michael J.; Doney, Scott C.; Lima, Ivan; Boss, Emmanuel S.; Siegel, David A. (American Geophysical Union, 2013-06-20)
    Satellite measurements allow global assessments of phytoplankton concentrations and, from observed temporal changes in biomass, direct access to net biomass accumulation rates (r). For the subarctic Atlantic basin, analy ...
  • Milligan, Allen J.; Aparicio, Uriel A.; Behrenfeld, Michael J. (Inter-Research, 2012-02-23)
    The fluorescence signal emitted from phytoplankton exposed to natural sunlight has been considered a potentially useful tool to examine phytoplankton physiology from in situ radiometers and satellites, but variability in ...
  • O'Malley, Robert T.; Behrenfeld, Michael J.; Westberry, Toby K.; Milligan, Allen J.; Shang, Shaoling; Yan, Jing (American Geophysical Union, 2014-07-17)
    Since June 2010, the Geostationary Ocean Color Imager (GOCI) has been collecting the first diurnally resolved satellite ocean measurements. Here GOCI retrievals of phytoplankton chlorophyll concentration and fluorescen ...
  • Siegel, D. A.; Buesseler, K. O.; Doney, S. C.; Sailley, S. F.; Behrenfeld, Michael J.; Boyd, P. W. (American Geophysical Union, 2014-03-10)
    The export of organic carbon from the surface ocean by sinking particles is an important, yet highly uncertain, component of the global carbon cycle. Here we introduce a mechanistic assessment of the global ocean carbo ...
  • Westberry, Toby K.; Williams, Peter J. le B.; Behrenfeld, Michael J. (American Geophysical Union, 2012-12-22)
    Reconciling rates of organic carbon export from the euphotic zone with the consumption of organic material in the dark ocean remains one of the major quantitative uncertainties of the ocean carbon cycle. Euphotic zone ne ...
  • O'Malley, Robert T.; Behrenfeld, Michael J.; Westberry, Toby K.; Milligan, Allen J.; Reese, Douglas C.; Halsey, Kimberly H. (Elsevier, 2014-01)
    Submarine volcanic eruptions can result in both real and apparent changes in marine algal communities, e.g., increases in phytoplankton biomass and/or growth rates that can cover thousands of square kilometers. Satellite ...
  • Siegel, D. A.; Behrenfeld, Michael J.; Maritorena, S.; McClain, C. R.; Antoine, D.; Bailey, S. W.; Bontempi, P. S.; Boss, E. S.; Dierssen, H. M.; Doney, S. C.; Eplee, R. E. Jr.; Evans, R. H.; Feldman, G. C.; Fields, E.; Franz, B. A.; Kuring, N. A.; Mengelt, C.; Nelson, N. B.; Patt, F. S.; Robinson, W. D.; Sarmiento, J. L.; Swan, C. M.; Werdell, P. J.; Westberry, T. K.; Wilding, J. G.; Yoder, J. A. (Elsevier Inc., 2013-08)
    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, the Sea-viewing Wide Field-of-vi ...
  • Behrenfeld, Michael J.; Hu, Yongxiang; Hostetler, Chris A.; Dall’Olmo, Giorgio; Rodier, Sharon D.; Hair, John W.; Trepte, Charles R. (American Geophysical Union, 2013-08-23)
    Global ocean phytoplankton biomass (C-phyto) and total particulate organic carbon (POC) stocks have largely been characterized from space using passive ocean color measurements. A space-based light detection and ranging ...
