Phytoplankton abundance in relation to cultural eutrophication at the land-ocean boundary of Sunderbans, NE Coast of Bay of Bengal, India
TLDR
In this article, seasonal fluctuations in the phytoplankton assemblage and the relationship between PHYTOPLankton abundance and key environmental parameters in a highly eutrophic system were reported.Abstract:
Human activities accelerate the input of plant nutrients sourced from agriculture, industrial waste, and sewage in the Hooghly River at the land ocean boundary of Indian Sunderban mangrove (21°32′–22°40′ N and 88°05′–89° E). This study reports seasonal fluctuations in the phytoplankton assemblage and the relationship between phytoplankton abundance and key environmental parameters in a highly eutrophic system. As far as seasonal perspective, the Hooghly estuarine system dominated by mangrove suffered complete change in terms of phytoplankton and other key parameters during monsoon compared to other times of the year. Diatoms were more abundant than dinoflagellates throughout all seasons with 58 species.read more

TL;DR: The fugacity of CO2 [fCO2 (water)] and air-water CO2 flux were compared between a river-dominated anthropogenically disturbed open estuary, the Hugli and a comparatively pristine mangrove dominated semi-closed marine estuary on the east coast of India as discussed by the authors.

Human waste: an underestimated source of nutrient pollution in coastal seas of Bangladesh, India and Pakistan.
TL;DR: This work quantifies nutrient export by large rivers to coastal seas of Bangladesh, India and Pakistan, and the associated eutrophication potential in 2000 and 2050 and estimates for N and P inputs from human waste are one to two orders of magnitude higher than earlier model calculations.

The increasing impact of food production on nutrient export by rivers to the Bay of Bengal 1970-2050.
TL;DR: The objective of this study is to assess the impact of food production on river export of nutrients to the coastal waters of the Bay of Bengal in the past and the future, and the associated potential for coastal eutrophication.

Natural and human controls of water quality of an Amazon estuary (Caeté-PA, Brazil)
TL;DR: In this article, the DPSIR framework was used as a guide for proposing potential measures to improve water quality in the Caete Estuary based on urban planning to control sewage discharges, construction of water treatment infrastructures to reduce untreated effluents inputs and water use regulations as a function of current water quality.

TL;DR: In this paper, the variability of nutrient concentrations (dissolved inorganic nitrogen, DIN; dissolved inorganic phosphorus, DIP; and dissolved in organic silicate, DSi) along with salinity, total suspended matter (TSM), chlorophyll- a (chl- a ) and dissolved oxygen (DO) were investigated in the shallow continental shelf waters of the northern Bay of Bengal.

The Mathematical Theory of Communication
TL;DR: The theory of communication is extended to include a number of new factors, in particular the effect of noise in the channel, and the savings possible due to the statistical structure of the original message anddue to the nature of the final destination of the information.

Measurement of diversity
TL;DR: In this article, the authors define and examine a measure of concentration in terms of population constants, and examine the relationship between the characteristic and the index of diversity when both are applied to a logarithmic distribution.
