Short summary

The Persian/Arabian Gulf exports a dense, salty, oxygen-rich current that helps ventilate the Arabian Sea. Measurements along the northern margin of the Gulf of Oman show that the flow remains thin and attached over smooth seafloor, but thickens, mixes, and detaches after a bathymetric step over rough terrain of the shelf. These changes affect oxygen delivery and benthic life, and also suggest that climate-driven density shifts may alter their pathways and impacts.
