Defining Petrophysical Units of the Palmer Deep Sites from Leg 178 [PDF]

open access: yes, 2002
Palmer Deep, on the inner continental shelf southwest of Anvers Island off the Antarctic Peninsula, is a glacially overdeepened basin consisting of three subbasins. Two sites, 1098 and 1099, were drilled in the Palmer Deep area.

Diatom-Bacteria Interactions Modulate the Composition and Productivity of Benthic Diatom Biofilms

open access: yesFrontiers in Microbiology, 2019
Benthic diatoms are dominant primary producers in intertidal mudflats and constitute a major source of organic carbon to consumers and decomposers residing within these ecosystems.

Long range intermolecular forces in triatomic systems: connecting the atom-diatom and atom-atom-atom representations

open access: yes, 2005
The long-range forces that act between three atoms are analysed in both atom-diatom and atom-atom-atom representations. Expressions for atom-diatom dispersion coefficients are obtained in terms of 3-body nonadditive coefficients.

Metatranscriptomic Signatures Associated With Phytoplankton Regime Shift From Diatom Dominance to a Dinoflagellate Bloom

open access: yesFrontiers in Microbiology, 2019
Diatoms and dinoflagellates dominate coastal marine phytoplankton communities as major players of marine biogeochemical cycles and their seasonal succession often leads to harmful algal blooms (HABs).

Substrate type selection in diatom based lake water quality assessment

open access: yesKnowledge and Management of Aquatic Ecosystems, 2021
Various studies report contrasting results on the substrate-type effect on diatom community composition, but the particularly important question is whether or not it affects diatom-based assessments of water quality. We investigated whether the substrate

Comparative algological and bacteriological examinations on biofilms developed on different substrata in a shallow soda lake [PDF]

open access: yes, 2008
According to the European Water Framework Directives, benthic diatoms of lakes are a tool for ecological status assessment. In this study, we followed an integrative sample analysis approach, in order to find an appropriate substratum for the water ...

Understanding Diatom Cell Wall Silicification—Moving Forward

open access: yesFrontiers in Marine Science, 2018
The silicified cell walls of diatoms have inspired the interest of researchers for several centuries, and our understanding of their properties and formation has developed in synch with the development of observational and analytical techniques. Over the

Research on the Characteristics of Benthic Diatom in the Longjiang River in Guangxi and Its Relationships with Heavy Metals Ions Pollution

open access: yesChemical Engineering Transactions, 2017
This paper performs sampling and analysis of benthic diatom communities in the Longjiang River in Guangxi province in both May and July. The positive correlation between dominant diatom communities and the contents of heavy metals in the water were ...

A tripartite model system for Southern Ocean diatom-bacterial interactions reveals the coexistence of competing symbiotic strategies

open access: yesISME Communications, 2022
Southern Ocean (SO) diatoms play an important role in global carbon flux, and their influence on carbon export is directly linked to interactions with epiphytic bacteria.
