Abstract Sedimentary pyrite formation links the global biogeochemical cycles of carbon, sulfur, and iron, which, in turn, modulate redox state planet's surficial environment over geological time scales. Accordingly, sulfur isotopic composition (δ34S) has been widely employed as a geochemical tool to probe evolution ocean chemistry. Characteristics depositional post-depositional processes, howev...

This research was carried out from March to April 2021 in the coastal area of ​​Kuala Jambi District, Tanjung Jabung Timur Regency, Province. The samples were processed at Marine Biology and Chemistry Laboratory, Faculty Fisheries Marine, Universitas Riau, which aims examine density mangroves, analyze sedimentation rate, know relationship between mangrove rate. A survey method used this study. ...

Abstract The transport of planktonic microbes from the upper ocean to sediments plays an important role in marine ecology and biogeochemistry (e.g., downward organic matter). In order have a better understanding this process, we investigated diversity allochthonous cyanophages, cyanobacteria, eukaryotic algae Pearl River Estuary South China Sea based on psbA , gene encoding D1 protein involved ...

A sediment model and retreat history for the Ross Ice (Sheet) Shelf in the Western Ross Sea since the Last Glacial Maximum" (2007). Related Publications from ANDRILL Affiliates. Summary Three sediment gravity cores collected from beneath the McMurdo Ice Shelf and six piston cores from the Erebus Basin (in McMurdo Sound) and the Lewis Basin (north of Ross Island) were analysed in order to constr...

The Rupat Strait on the eastern coast of Sumatera Island is currently undergoing a geomorphological process due to current system, which flows from Malacca Strait, and change use hinterland. main purpose this study identify dynamic by analyzing changes width depth strait. We propose remote sensing method using satellite imagery evaluate depth. was also measured echo sounding at 60 stations. stu...

Estuary and coastal environments are a ‘‘sink’’ for contaminants, including manufactured nanomaterials (MNMs) (Klaine et al. 2008). MNMs may enter the marine environment via rainwater, wastewater, and river transportation. Harbor handling may also result in MNM leakage and deposition in harbor areas. Dumping wastes such as nanowaste, trash containing MNMs, and harbor-dredging, mudcontaining MNM...

Marine biology is a hybrid subject that combines aspects of organismal function, ecological interaction and the study of marine biodiversity.[1] The earliest studies of marine biology can be traced back to the Phoenicians and the Greeks who are known as the initial explorers of the oceans and their composition.[2] However, it was Aristotle (384-322 BC) who was the first to record any observatio...

Flocculation achieved by raising the pH, termed alkaline flocculation is a sustainable way of inducing in marine microalgae. Flocs formed post-alkaline have potential to be harvested via dissolved air flotation (DAF) or sedimentation. While DAF results faster separation and biomass with higher solids content compared sedimentation, it has not been tested saline environments, particularly when c...
