Surface pCO2 variability in two contrasting basins of North Indian Ocean using satellite data

چکیده
The spatial and temporal variability of the partial pressure carbon dioxide (pCO 2 ) over northern tropical Indian Ocean was estimated based on satellite-derived sea surface temperature (SST), salinity (SSS), chlorophyll concentration (Chl-a). distribution pCO is controlled by various physical processes, such as mixing, entrainment, upwelling, advection, associated biological phytoplankton blooms. results showed lower water Bay Bengal (BoB) (< 300 μatm) compared to Arabian Sea (AS), which could be attributed low during northeast monsoon season (December–January) in BoB. High values (> 500 were found near Somali coast southwest (June–August) caused intense coastal upwelling.

Introduction: The study’s main aim is to investigate the long-term variation of Aerosol Optical Depth (AOD). It also aims to show the relationship between meteorological parameters. This study evaluates long-term (2010 to 2021) special and temporal changes over major Indian regions using satellite-based data from NASA’s Terra Satellite. Materials and Methods: This study was carried out during ...

Recently, both Persian Gulf and Gulf of Oman are experiencing several types of pollution including oil spills and heavy metal pollutions as well as Harmful Algal Bloom (HAB) caused by biological and environmental changes. Theiroccurrence of the red tide or harmful algal bloom during fall and winter 2008-2009 caused numerous unknown factors in the Strait of Hormuz, Persian Gulf and G...
متن کاملData-based estimates of the ocean carbon sink variability – First results of the Surface Ocean pCO2 Mapping intercomparison (SOCOM)
Using measurements of the surface-ocean CO2 partial pressure (pCO2) and 14 different pCO2 mapping methods recently collated by the Surface Ocean pCO2 Mapping intercomparison (SOCOM) initiative, variations in regional and global sea–air CO2 fluxes are investigated. 5 Though the available mapping methods use widely different approaches, we find relatively consistent estimates of regional pCO2 sea...
