Ocean primary production and available light: Further algorithms for remote sensing
In the context of remote sensing of the ocean, the general problem of estimating water column production from surface irradiance and column chlorophyll concentration is examined, and some refinements are made to the linear ...
Changes in the marine green alga @iChaetomorpha media@@ on infection by a fungal pathogen
(Walter de Gruyter, Berlin, 1988)
Biochemical changes in the green filamentous alga @iChaetomorpha media@@ Kutzing infected with a holocarpic endobiotic fungus@@ Pontisma lagenidioides@@ Petersen were studied. Healthy plants of @iC. media@@ were inoculated ...
A preliminary study of anaerobic thiosulfate-oxidising bacteria as denitrifiers in the Arabian Sea
(Taylor & Francis, 1988)
Bacteria which oxidize thiosulfate and reduce nitrate (TONRB) and bacteria which oxidize thiosulfate and denitrify (TODB) sampled at 5-, 100-, 200-and 300-m depths were enumerated in agar shake cultures by colony counting ...
The Indian Ocean - An environmental overview
During the International Indian Ocean Expedition (IIOE), 1962-65, the Indian Ocean was defined as the area between 25 degrees N and 40 degrees S latitudes and 45 degrees E longitudes. This region included all the straits, ...
Marine nitrogen cycling- Some recent observations in the northwestern Indian Ocean
(Trivandrum: University of Kerala, 1987)
Published estimates of the rate of denitrification in the Arabian Sea have been evaluated and some new data on the nitrogen cycle have been presented Secondary nitrite maxima and nitrate reduction appear to be associated ...
Production of krill E. superba (Dana 1852) in the Antarctic waters

Thraustochytrid fungi associated with marine algae
Many of the diatoms collected from Arabian Sea were found to harbour thraustochytrid fungi on them. The fungus was identified as Ulkenia visurgensis and it could be grown on pine pollen in seawater. The fungus never infected ...
Chytridium polysiphoniae - a fungal pathogen on the Red alga Centroceras clavulatum (C. Agardh) Montagne, from Goa
Centroceras clavulatum collected from rocky shores was found to harbour an epiphytic fungus identified as Chytridium polysiphoniae. Maximum infection of the host alga occurred during June-July 1984. Under laboratory ...
