Remote Estimation Of The Diffuse Attenuation Coefficient In A Moderately Turbid Estuary, Richard P. Stumpf, Jonathan Pennock Dec 1991

Remote Estimation Of The Diffuse Attenuation Coefficient In A Moderately Turbid Estuary, Richard P. Stumpf, Jonathan Pennock

School of Marine Science and Ocean Engineering

Abstract

Solutions of the radiative transfer equation are used to derive relationships of water reflectance to the diffuse attenuation coefficient (K) in moderately turbid water (K > 0.5 m−1). Data sets collected from the NOAA AVHRR and in situ observations from five different dates confirm the appropriateness of these relationships, in particular the logistic equation. Values of K calculated from the reflectance data agree to within 60% of the observed values, although the reflectance derived using a more comprehensive aerosol correction is sensitive to chlorophyll concentrations greater than 50 μg L−1. Agreement between in situ and remote …


Variation In A Host-Epiphyte Relationship Along A Wave Exposure Gradient, Phillip S. Levin, Arthur C. Mathieson Nov 1991

Variation In A Host-Epiphyte Relationship Along A Wave Exposure Gradient, Phillip S. Levin, Arthur C. Mathieson

New Hampshire Agricultural Experiment Station Publications

The red alga Polysiphonia lanosa (L ) Tandy is an obligate epiphyte that primarily occurs on the fucoid brown algal basiphyte Ascophyllum nodosum (L) Le Jolis In the present study we examine how epiphytic interactions between P lanosa and A nodosum vary along a wave exposure gradient within the southern Gulf of Maine, USA P lanosa was most dense on protected shores, however because the stature of P lanosa was greater on exposed than on sheltered shores, greater biomass occurred In exposed habitats Epiphytlc P lanosa pnmanly attached to inlured vegetative bssue at exposed sites, while ~ t osc currence …

Regulating Air Toxics In Rhode Island: Policy Vs. Technical Decisions, Julie A. Roque Mar 1991

Regulating Air Toxics In Rhode Island: Policy Vs. Technical Decisions, Julie A. Roque

RISK: Health, Safety & Environment (1990-2002)

Dr. Roqu6 recounts her work as a doctoral candidate at Brown in developing standards for the regulation of airborne carcinogens. Based in part on this experience, she argues that care needs be taken lest those who regulate Risk bury key policy decisions within a mass of often irrelevant technical details.

Pharmaceutical Risk And The Quality Of Life, Beat Hiltbrunner, Andreas Breitsprecher Jan 1991

Pharmaceutical Risk And The Quality Of Life, Beat Hiltbrunner, Andreas Breitsprecher

RISK: Health, Safety & Environment (1990-2002)

Quality-of-life research is briefly described and said to be in its infancy. However, the authors observe that such studies may, e.g., make it possible to better match patients and therapies. They also predict that, as scientific difficulties are overcome, the pharmaceutical industry will become more active in planning, implementing and evaluating such research.
