Fabrication of Biomass-Polymeric Adsorbent for the Removal of Selected Metal Species, Nutrients and Pathogens in Aqueous Solutions
… successfully developed and evaluated a systemic biomass polymeric adsorbent for the removal of toxic metals such as chromium and cadmium ions, nutrients (nitrate and phosphate ions), and pathogens from aqueous solutions. The bio-sorbent was fabricated by incorporating biomass (grapefruit peels) …

Phytoplankton dynamics in the northeast subarctic Pacific during the 1998 El Niño, the 1999 La Niña and 2000 with special consideration to the role of coccolithophores and diatoms
… were similar to 1998 in late summer. Near-shelf biomass was highest in June and lowest in Feb. for the near-shelf stations. High nitrate, low chlorophyll (HNLC) stations had the highest chlorophyll in Feb. followed by June. The coccolithophore assemblage was usually numerically dominated by …

Characterization of biofuel from diatoms via hydrothermal liquefaction
… low lipid microalgae to produce bio-crude oil. Diatoms are a major group of microalgae in water bodies with a high growth rate and that contribute about 20% of global primary production. Their unique frustule (silica cell wall) results in a high ash content (39% dry weight). This character makes …

Antarctic phytoplankton and climate change using Holocene sedimentary DNA, fossils and chemical proxies.
… the WAP is a highly productive ecosystem, with diatom-rich spring/summer phytoplankton blooms supporting populations of zooplankton and higher trophic levels and driving an efficient biological pump important for the carbon cycle. Current instrumental and satellite records span only recent …

Shelf biogeochemical interactions and feedback processes in the Benguela upwelling system
… is high in coastal waters due to ballasting of diatom biomass. The models used in this study simulated biogeochemical interactions in the Benguela fairly-well and can be applied in other regions.
