Recent foraminifera from nearshore shelf, south of Visakhapatnam, east coast of India
Title: Recent foraminifera from nearshore shelf, south of Visakhapatnam, east coast of India
Authors: Kaladhar, R; Kamalakaram, S; Varma, K U; Rao, V Bhaskara
Abstract: Forty two species of Foraminifera are recognised from the sediments of inshore waters (3-10 m depth). Both living and dead individuals of Foraminifera have been studied. The assemblage is devoid of agglutinated forms.
Composition of microfouling on aluminum and fiber glass panels exposed in Agatti waters (Lakshadweep Island)
Title: Composition of microfouling on aluminum and fiber glass panels exposed in Agatti waters (Lakshadweep Island)
Authors: Raveendran, T V; Sankaran, P D; Wagh, A B
Abstract: Rate of microfouling build-up was high during the initial periods of exposure of test surfaces but decreased with the increasing duration. Fibre glass surfaces showed higher deposition than those of aluminium. Carbohydrates and lipids were the major constituents of fouling mass as compared to proteins. Fouling diatoms were dominated by the pennate forms (Nitzschia, Navicula and Biddulphia).
Marine fouling on test panels and in-service structural steel in Tuticorin harbour
Title: Marine fouling on test panels and in-service structural steel in Tuticorin harbour
Authors: Maruthamuthu, S; Eashwar, M; Manickam, S T; Ambalavanan, S; Venkatachari, G; Balakrishnan, K
Abstract: Barnacles, molluscs and ascidians were the major foulants in Tuticorin harbour. The annual fouling load reached about 5 kg.m-2 on aluminum test panels. Marine growth, principally by molluscs, was more on steel liners and thickness values exceeded 2.5 cm. Of the 42 sessile species sampled, Balanus tintinnabulum and Crassostrea cristagalii produced most orrosion damage to underwater steel structures.
Nitrate and ammonium uptake by alga Sargassum swartzii (Turn.) C. Ag. (Phaeophyta)
Title: Nitrate and ammonium uptake by alga Sargassum swartzii (Turn.) C. Ag. (Phaeophyta)
Authors: Ramalakshmi, Y; Chauhan, D V
Abstract: Uptake of nitrate in S. swartzii is reduced in dark but enhanced in light 50±2 uE m-2 s-1. No such difference between light and dark uptake of ammonium is seen. When nitrate and ammonium are added together in the incubation medium, these are taken up simultaneously. Slight inhibition of nitrate uptake is seen in presence of ammonium, but ammonium uptake is not affected by the presence of nitrate. At a given particular concentration of nitrate and ammonium, apical portions are more active in taking up the nutrients compared to the basal portions.
