Effects of microalgal communities on reflectance spectra of carbonate sediments in subtidal optically shallow marine environments

Autor: F. Carol Stephens, R. Pamela Reid, Robert A. Maffione, Eric M. Louchard

Publikováno v: Limnology and Oceanography. 48:535-546

This study was conducted in subtidal areas around Lee Stocking Island, Bahamas, to investigate how microalgal biomass and community structure affect hyperspectral reflectance of sediments. Hyperspectral reflectance was measured on the surfaces of sed

Publikováno v: ResearcherID

Microbial communities often produce copious films of extracellular polymeric secretions (EPS) that may interact with sediments to influence spectral reflectance signatures of shallow marine sediments. We examined EPS associated with microbial mats to

Optical remote sensing of benthic habitats and bathymetry in coastal environments at Lee Stocking Island, Bahamas: A comparative spectral classification approach

Autor: Curtiss O. Davis, R. Pamela Reid, Robert A. Leathers, F. Carol Stephens, Eric M. Louchard, T. Valerie Downes

Publikováno v: Limnology and Oceanography. 48:511-521

Remote sensing is a valuable tool for rapid identification of benthic features in coastal environments. Past applications have been limited, however, by multispectral models that are typically difficult to apply when bottom types are heterogeneous an

Publikováno v: Goodwin, KD; Tokarczyk, R; Stephens, FC; & Saltzman, ES. (2005). Description of toluene inhibition of methyl bromide biodegradation in seawater and isolation of a marine toluene oxidizer that degrades methyl bromide.. Appl Environ Microbiol, 71(7), 3495-3503. doi: 10.1128/AEM.71.7.3495-3503.2005. UC Irvine: Retrieved from: http://www.escholarship.org/uc/item/1t85201j

Methyl bromide (CH 3 Br) and methyl chloride (CH 3 Cl) are important precursors for destruction of stratospheric ozone, and oceanic uptake is an important component of the biogeochemical cycle of these methyl halides. In an effort to identify and cha

ULTRASTRUCTURE STUDIES ON SOME MASTOGLOIA SPECIES OF THE GROUP INAEQUALES (BACILLARIOPHYCEAE)1

Autor: Robert A. Gibson, F. Carol Stephens

Publikováno v: Journal of Phycology. 16:354-363

Five species of the diatom genus Mastogloia (group Inaequales) were studied using transmitted light (TLM) and scanning electron (SEM) microscopy. Specimens for study were collected from the Indian River, Florida (salinity 16–42‰c temperature 9–
