Short summary
This research examines ocean conditions in the Indonesian seas, a key area linking the Pacific and Indian Oceans. We analyzed two centuries of direct ocean measurements and found large gaps in deep-sea and coastal data that limit climate and marine studies. We suggest better monitoring, technology, and collaboration to improve understanding of ocean changes. These efforts will help predict climate impacts and support marine conservation and sustainable resource use.

Short summary
We provide new insights on the presence of oxygen-depleted waters along the Indonesian coasts of Sumatra and Java attributed to the eastward advection of the northern Indian Ocean waters and monsoon-driven upwelling. Combined in situ and reanalysis data elucidate the complex interplay of oceanographic processes responsible for the observed oxygen in the region. The knowledge is crucial for research and management strategies to mitigate deoxygenation impacts on marine ecosystems in Indonesia.

Short summary
Detailed ocean currents in the southeastern tropical Indian Ocean have not been fully explained because of limited observations. Here, zonal current characteristics in the region have been studied using 64-year HYCOM results (1950–2013). This study has revealed distinctive features of current variations on various timescales. Current vertical structures, their responses to remote forcings from the Pacific and Indian oceans, and contributions of each timescale have all been investigated.
