Spectral backscattering properties of marine phytoplankton cultures

Creator:

Whitmire, Amanda L., Pegau, W. Scott, Karp-Boss, Lee, Boss, Emmanuel, and Cowles, Timothy J.

Abstract:

The backscattering properties of marine phytoplankton, which are assumed to vary widely with differences in size, shape, morphology and internal structure, have been directly measured in the laboratory on a very limited basis. This work presents results from laboratory analysis of the backscattering properties of thirteen phytoplankton species from five...

Distribution and variability of iron input to Oregon coastal waters during the upwelling season

Creator:

Chase, Zanna, Hales, Burke, Cowles, Timothy J., Schwartz, Roseanne, and van Geen, Alexander

Abstract:

We measured iron concentrations off the Oregon coast in spring (May–June) and summer (August) of 2001 as part of the Coastal Ocean Advances in Shelf Transport (COAST) program. Dissolvable and total dissolvable iron levels in surface waters were generally higher in spring (mean of 2.1 and 33.9 nmol L¯¹, respectively)...
