The formation of carbonate build-ups associated with seafloor methane vents – where microbially mediated sulphate-dependent anaerobic oxidation produces alkalinity is well documented in modern marine environments and the geologic record. However, triggering event(s) behind processes leading to hydrocarbon disequilibrium, seeping consequent deposition seep-carbonates remain poorly constrained. T...

Benthic communities below the photic zone are largely reliant on export of surface-water primary production and flux partially degraded organic matter to seabed, i.e. pelagic?benthic coupling. Over past decades, however, role chemosynthetically produced carbon in food webs has been recognized various habitats. Cold seeps now known be widespread across circumpolar Arctic shelves where natural re...

Multibeam echosounder water column data provides a three-dimensional image of features between the surface and seafloor. Although this swath acoustic can be collected over wide range angles, most data, at least beyond to first seafloor return, is contaminated by noise created receiver array sidelobe interference. As result, minimum slant commonly excluded from analysis. This paper demonstrates ...

Abstract: Rainfall is the height of rainwater in a rain gauge on flat place that does not seep and flow, where rainfall measured millimeters (mm). This study aims to estimate model for DKI Jakarta Province from January 2016 December 2021 using Fourier series estimation. Based results study, with minimum GCV value 21909,4, at 7th

Trypan blue is common in visualizing the anterior capsule during cataract surgery. Inadvertent staining of the posterior capsule during phacoemulsification is a rare complication and there are few reports in the literature. The proposed mechanism of posterior capsule staining in previous reports includes a compromised zonular apparatus or iris retractors facilitating the posterior flow of trypa...

The 28th species of the eelpout genus Pachycara Zugmayer, 1911, is described from specimens collected from an active hydrothermal vent field at a depth of about 2300 m at the Mid-Cayman Spreading Centre of the Caribbean Sea. A tentatively identified early juvenile is recorded at a methane seep at a depth of 1049 m near Tobago. The new species is distinguished from its congeners mainl...
