Optical properties of the clearest natural waters (200–800 nm)
Raymond C. Smith,Karen S. Baker +1 more
TL;DR: A comparative analysis and new data allow a consistent and accurate set of optical properties for the clearest natural waters and for pure fresh water and saltwater to be estimated from 300 to 800 nm.
Journal ArticleDOI
A semianalytic radiance model of ocean color
Howard R. Gordon,Otis B. Brown,Robert Evans,James W. Brown,Raymond C. Smith,Karen S. Baker,Dennis K. Clark +6 more
TL;DR: In this article, a semianalytical radiance model is developed which predicts the upwelled spectral radiance at the sea surface as a function of the phytoplankton pigment concentration for Morel Case 1 waters.
Journal ArticleDOI
Ozone depletion: ultraviolet radiation and phytoplankton biology in antarctic waters.
Raymond C. Smith,Barbara B. Prézelin,Karen S. Baker,Robert R. Bidigare,N. P. Boucher,Teresa L. Coley,D. Karentz,Sally Macintyre,H. A. Matlick,D. Menzies,Michael Ondrusek,Zhengming Wan,Kirk Waters +12 more
TL;DR: Results from a 6-week cruise in the marginal ice zone of the Bellingshausen Sea in austral spring of 1990 indicated that O3-dependent shifts of in-water spectral irradiances alter the balance of spectrally dependent phytoplankton processes, including photoinhibition, photoreactivation, photoprotection, and photosynthesis.
Journal ArticleDOI
Marine pelagic ecosystems: the West Antarctic Peninsula
Hugh W. Ducklow,Karen S. Baker,Douglas G. Martinson,Langdon B. Quetin,Robin M. Ross,Raymond C. Smith,Sharon Stammerjohn,Maria Vernet,William R. Fraser +8 more
TL;DR: The marine ecosystem of the West Antarctic Peninsula is one among the most rapidly warming regions on Earth, having experienced a 2°C increase in the annual mean temperature and a 6°C rise in the mean winter temperature since 1950.
Book ChapterDOI
Toward Information Infrastructure Studies: Ways of Knowing in a Networked Environment
TL;DR: It is argued that a theoretical understanding of infrastructure provides the context for needed dialogue between design, use, and sustainability of internet-based infrastructure services and the character of the field today is considered.
