Biological processes and optical measurements near the sea surface: Some issues relevant to remote sensing
(1995)There is good evidence that bio-optical relationships are altered near the surface: (1) the fluorescence yield from chlorophyll declines, leading to bias in the estimation of pigment from fluorometry; (2) the modeled ... -
A semi-analytical model of the influence of phytoplankton community structure on the relationship between light attenuation and ocean color
(1999-01)A model was developed to examine the influence of phytoplankton community structure on the relationship between diffuse attenuation and ratios of upwelling radiance. Shifts in phytoplankton communities were represented by ... -
Assessment of the relationships between dominant cell size in natural phytoplankton communities and the spectral shape of the absorption coefficient
(2002-03)Size-fractionated chlorophyll concentration and phytoplankton absorption spectra were compared for a wide variety of natural communities. We found that, in general, when phytoplankton abundance increases, larger size-classes ... -
Quantifying particle dispersal in aquatic sediments at short time scales: model selection
(2008)In a pulse-tracer experiment, a layer of tracer particles is added to the sediment-water interface, and the down-mixing of these particles is followed over a short time scale. Here, we compared different models (biodiffusion, ... -
Bioturbation and porosity gradients
(1998-01)Ubiquitous porosity gradients have a potentially important effect on the mixing of particle-bound tracers, such as Pb-210. Mass-depth coordinates cannot be used to deal with these effects if values of the traditional mixing ... -
What controls the mixed-layer depth in deep-sea sediments? The importance of particulate organic carbon flux
(2004-03)No abstract available. -
Early diagenesis in a marine sapropel, Mangrove Lake, Bermuda

Rate of growth of isolated bubbles in sediments with a diagenetic source of methane
(American Society of Limnology and Oceanography, Ann Arbor, MI, 2001-05)Observation of bubbles in estuarine and coastal sediments indicates that bubbles at or below 10 cm depth grow on seasonal time scales (May-October). In order to determine the controls on this growth rate, we have constructed ... -
Mean mixed depth of sediments; the wherefore and the why
(American Society of Limnology and Oceanography, Ann Arbor, MI, 1998-05)No abstract available. -
Last gasp of the Grenville Orogeny; thermochronology of the Grenville Front tectonic zone near Killarney, Ontario
(University of Chicago Press, Chicago, IL, 1993-09)No abstract available. -

Evolution of orogenic wedges and continental plateaux: insights from crustal thermal-mechanical models overlying subducting mantle lithosphere
(2003-04)The links between an early phase of orogenesis, when orogens are commonly wedge shaped, and a later phase, with a plateau geometry, are investigated using coupled thermal-mechanical models with uniform velocity subduction ...
