Performance of Honeywell silicon pressure transducers
(Allied, India, 2003)Simultaneous calibration of three Honeywell pressure transducers (PPTR) at four ambient temperatures have been carried out using a novel static calibration system developed in-house. Calibration results indicated that ... -
Performance of the ocean state forecast system at Indian National Centre for Ocean Information Services
(Current Science Association, 2013)The reliability of the operational Ocean State Forecast system at the Indian National Centre for Ocean Information Services (INCOIS) during tropical cyclones that affect the coastline of India is described in this article. ... -
Period and length of high surface gravity waves measured in the coastal waters of eastern Arabian Sea and its variations in 10 years
(Elsevier, 2023)Information on the period and length of waves is required for the planning and design of marine facilities and wave energy converters. In this article, the period and length of the waves measured during the peak monsoon ... -
Periodic deformation of oceanic crust in the central Indian Ocean
(AGU, 1998)New seismic reflection profiles of ~~ 5370 km, running through the Ocean Drilling Program Leg 116 sites and Deep Sea Drilling Project Sites 215 and 218, were obtained to investigate the spatial extent, timing, and nature ... -
Persistence and fate of some organophosphorus pesticides in sea sediments along east coast of India
(CSIR-NISCAIR, 1986)Stability and fate of pesticides, monocrotophos, phosphamidon and DDVP, were studied in sediment samples collected along the east coast of India pH, salinity and exchangeable cations present in sediments exhibited profound ... -
Persistence of fecal indicator bacteria associated with zooplankton in a tropical estuary-west coast of India
(2019)In a study carried out during 2014, bacteria associated with zooplankton in the Zuari estuary were 3– 4 orders of magnitude higher in abundance than in seawater. The live zooplankton carried much more bacterial load ... -
Persistent increase in carbon burial in the Gulf of Mannar, during the Meghalayan Age: Influence of primary productivity and better preservation
(Cambridge University Press, 2023)The oceans store a substantial fraction of carbon as calcium carbonate (CaCO3) and organic carbon (Corg) and constitute a significant component of the global carbon cycle. The Corg and CaCO3 flux depends on productivity ... -
Persistent volcanic signature observed around Barren Island, Andaman Sea, India
(Springer, 2006)This study delineates the formation of a warm pool (> 33°C) of air to the west (downwind) of the active volcano of the Barren Island during October-November 2005. Barren Island is located in the Sumatra-Andaman region, ... -
Perspectives in oceanographic research - A tribute to Borje Kullenberg

Perspectives on the terrestrial organic matter transport and burial along the land-deep sea continuum: Caveats in our understanding of biogeochemical processes and future needs
(Frontiers Media, 2016)The natural carbon cycle is immensely intricate to fully understand its sources, fluxes and the processes that are responsible for their cycling in different reservoirs and their balances on a global scale. Anthropogenic ... -
Pesticide application inhibit the microbial carbonic anhydrase-mediated carbon sequestration in a soil microcosm
(Springer, 2020)Heterotrophic system for carbon sequestration is gaining importance in the recent decades. Carbonic anhydrase (CA) is a major enzyme involved in carbon sequestration and biomineralization process. In this paper, we evaluate ... -
Pesticide residues in sediments from the west coast of India
(Pergamon, 1991)An average of 55,000 t of pesticides (including or organochlorine compounds) are used every year in India for agricultural purposes. The cumulative effects of these pesticides on the coastal environment can be expected to ... -
Pesticide residues in the sediments from the lakes of Schirmacher Oasis, Antarctica
(Cambridge University Press, 1994) -
Petasaria heterolepis (Prymnesiaceae) from the southern Indian Ocean
(Micropaleontology Press, 2015)Sea surface and sub-surface (0-110m) water samples were collected from the Southern Indian Ocean between 39°S and 65°S (along ~48°E and 57.3°E) during the austral summer of 2010 which yielded Petasaria heterolepis Out of ... -

Petrogenesis of ferromanganese nodules from east of the Chagos Archipelago, Central Indian Basin, Indian Ocean
(Elsevier, 1999)Deep-sea ferromanganese nodules occur over a large area and on many different sediment types of the Central Indian Basin, Indian Ocean. Selected samples were studied to determine their chemical and mineralogical compositions ... -
Petrogenesis of HED clan meteorites: Constraints from crystal size distribution
(Springer, 2023)Two diogenites (Johnstown and ALHA 77256) and two eucrites (Malotas (b) and Stannern) meteorites from the Howardite-Eucrite-Diogenite (HED) clan are investigated by petrography, mineral chemistry and using crystal size ... -
Petrogenetic evolution of Cretaceous Samchampi-Samteran Alkaline Complex, Mikir Hills, Northeastern India: Implications on multiple melting events of heterogeneous plume and metasomatized sub-continental lithospheric mantle
(Elsevier, 2017)The Samchampi (26° 13' N: 93° 18' E)-Samteran (26° 11' N: 93° 25' E) alkaline complex (SSAC) occurs as an intrusion within Precambrian basement gneisses in the Karbi-Anglong district of Assam, Northeastern India. This ... -
