摘要	The Maritime Continent (MC), a critical region for inter-basin climate interaction, harbors the world's highest marine biodiversity. Ocean warming in the MC, although with notable impacts on regional climate and marine ecosystems, remains poorly constrained by observations. By applying a volume-correction algorithm to existing gridded observational data sets, this study provides an estimate for the ocean heat content (OHC) change of the MC. The results suggest a substantial OHC increase of 2.65 +/- 0.46 Zettajoules during 1990-2015 (1.08 +/- 0.17 W m(-2)) and limited changes before and after. This increase primarily arose from the enhanced Pacific Walker circulation, which drove a convergence of upper-layer warm water toward the MC. A potential heat storage "hotspot" with enhanced warming below 500 m emerges within the Sulu Sea, which is supported by analysis of profile data collected in boreal winter but not in other seasons. Plain Language Summary The Maritime Continent (MC) between the Pacific and Indian Oceans is a tropical region of numerous islands separating small sea basins. This region possesses the highest marine biodiversity of the world, which has been affected by the warming climate. How much the MC has warmed awaits assessment. In this work, we applied a volume-correction method to existing observational data sets to improve the estimate of ocean heat content (OHC) change. We found that the OHC of the MC increased abruptly by 2.65 +/- 0.46 Zettajoules during 1990-2015, equivalent to 1.08 +/- 0.17 W m(-2), and showed limited changes before and after this period. This increase was mainly caused by stronger than normal Pacific trade winds. Notably, the Sulu Sea showed stronger warming below 500 m than other seas of the MC, which is particularly robust in boreal winter.
