Dissolved organic phosphorus concentrations in the northeast subarctic Pacific Ocean
(1992)
Shipboard determinations of dissolved organic P (DOP) concentrations were made for NE subarctic Pacific Ocean samples with three different oxidation-hydrolysis methods: UV irradiation, acid persulfate digestion, and a ...
Symmetry, change, perturbation, and observing mode in natural communities
(1986)
Like a kaleidoscope, nature presents continuously fleeting images of natural communities. It has been difficult to discern patterns of community structure in these elusive images. For both theoretical and applied considerations, ...
Modelling phase shifts in a rocky subtidal ecosystem
(Inter-Research, Nordbuente 23 Oldendorf/Luhe 21385 Germany, [mailto:ir@int-res.com],
[URL:http://www.int-res.com/], 2008-03)
The rocky subtidal ecosystem of the Atlantic coast of Nova Scotia is characterised by 2
community states, kelp beds and urchin barrens that alternate on a decadal time scale. While the
shift from barrens to a kelp bed ...
Inferred influence of nutrient availability on the relationship between Sun-induced chlorophyll fluorescence and incident irradiance in the Bering Sea
(American Geophysical Union, 2000 Florida Ave., N.W. Washington DC 20009 USA, [mailto:service@agu.org], [URL:http://www.agu.org], 2008-08)
This study examines variability in the relationship between Sun-induced chlorophyll fluorescence and incident solar irradiance as a potential diagnostic of the nutritional status of phytoplankton. The study site is the ...
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 description of water types on the Mackenzie Shelf of the Beaufort Sea during winter
(1992)
For a number of years during the 1980s, observations of the physical and chemical properties of seawater in the southeastern Beaufort Sea have been acquired in late winter. The most complete data set, from 1987, has been ...
