TL;DR: The low phytoplankton biomass and high ammonium concentrations argue that active grazing populations may be responsible for preventing diatom-dinoflagellate populations from establishing themselves to bloom proportions in the eastern Arabian Sea during the early NE monsoon.

01 Jun 1994TL;DR: In this article, a decoupling of denitrification from primary production, unique to the Arabian Sea, is revealed by nitrite, electron transport system (ETS) activity and bacterial production data.
Abstract: Recent information on some consequences of the acute mid-water oxygen deficiency in the Arabian Sea, especially on carbon-nitrogen cycling, is reviewed. An evaluation of published estimates of water column denitrification rate suggests an overall rate in the vicinity of 30Tg Ny-1, but the extent of benthic contribution remains unknown. A decoupling of denitrification from primary production, unique to the Arabian Sea, is revealed by nitrite, electron transport system (ETS) activity and bacterial production data. Results of both enzymatic and microbiological investigations strongly point to a major role of organic carbon other than that sinking from surface layers in supporting denitrification. Although denitrification is associated with an intermediate nepheloid layer, it seems unlikely that the excess carbon comes with particles re-suspended along the continental margins and transported quasi-horizontally into the ocean interior; instead, the particle maximum may directly reflect a higher bacterial abundance. It is proposed that denitrification may be predominantly fuelled by the dissolved organic matter.

TL;DR: In this article, two sediment cores from the southwestern continental margin of India were studied for their clay mineral composition and grain size parameters, and the results indicated that the clay mineral parameters can be used as proxies for the intensity of summer monsoon precipitation in the past.

TL;DR: In this paper, the convective/advective balance at the northern end of the Gulf of Elat was investigated by comparing observed data to a numerical model's predictions, and the results indicated a continuously developing annual cycle with the water column reaching vertical homogeneity in February and the new thermocline beginning to develop in March.

TL;DR: In this article, a review lists selected bis(indolyl)methane analogues reported from different natural sources to date, together with their biological properties and synthesis, and concludes that these molecules display a wide range of biological properties (antibacterial, antiviral, anti-oxidant, neurotoxic activity etc.).
Abstract: Bis(indolyl)methane (BIM) alkaloids are an important group of bioactive natural products predominantly found in marine organisms. Thus, compounds like arsindoline A and B, vibrindole A, arundine, and trisindoline are found in marine bacteria, while the related compound, streptindole is obtained from Streptococcus faecium IB 37, found in human feces. In recent years, these molecules, which display a wide range of biological properties (antibacterial, antiviral, anti-oxidant, neurotoxic activity etc.), have attracted the attention of several synthetic and natural product chemists. This review lists selected bis(indolyl)methane analogues reported from different natural sources to date, together with their biological properties and synthesis. 1 Introduction 2 Occurrence, Isolation, Structure Elucidation, and Biological Activity 3 Synthetic Approaches towards Bis(indolyl)methanes 4 Conclusions
