Warming of the Indian Ocean and its impact on temporal and spatial dynamics of primary production

The Impact of Recent Climate Change on the Global Ocean Carbon Sink

“…Among others, there are extensive areas in the northern Indian Ocean where increased outgassing is found due to a combination of warming, weakening winds, and a shallower mixed layer. In particular in the Arabian Sea, the primary driver of increased outgassing is a decrease in biological productivity caused by stronger stratification and warming, which is also evident from observations (Dalpadado et al, 2021;Roxy et al, 2016). Furthermore, an intensification of upwelling-favorable winds, as observed by Sydeman et al (2014) and Varela et al (2015), drives increased outgassing in the California, Humboldt, Benguela and south-west Australian Boundary Upwelling Systems.…”

Understanding the Seasonality, Trends, and Controlling Factors of Indian Ocean Acidification Over Distinctive Bio‐Provinces

“…The latter looked at trends in acidification focused only on the WAS. Dalpadado et al (2021) observed the IO for 22 years and reported an average increase in SST of 0.3°C-0.7°C over its various regions. Though this warming is expected to increase the acidification of those regions, Dalpadado et al (2021) has found no significant changes in the primary productivity, barring a few regions in the north IO showing a small decrease in trend.…”

Identification of acidification hotspots also provides an insight to address the complex interplay between pH dynamics and the biological productivity in those regions.…”

Air‐Sea Fluxes of CO2 in the Indian Ocean Between 1985 and 2018: A Synthesis Based on Observation‐Based Surface CO2, Hindcast and Atmospheric Inversion Models

“…The decrease in the rate of warming due to aerosols was reported in the northern Indian Ocean (Sridevi et al, 2023). The decrease in the primary production in the western Indian Ocean (Roxy et al, 2016;Dalpadado et al, 2021;Sridevi et al, 2023), was reported due to the decline in wind speed and upwelling intensity. The lack of primary productivity trends due to an increase in the deposition of nutrients from the atmosphere was reported Sridevi et al, 2023).…”
