Could anyone supply an ultra-high resolution bathymetric map between the Pagani River mouth and Pemba Island (Tanzania)?

For my paleo-drainage and sediment transport study, I need detailed bathymetry to map shelf morphology and identify possible submerged river channels. Public datasets like GEBCO are too coarse (30 arc-second). I need at least 5-10 meter resolution multibeam data. Are there specific marine survey institutions, national archives, or collaborative research projects that might have collected and would share such data for this area?

Acquiring such specific, high-resolution data can be challenging. I would start by querying the SeaDataNet infrastructure and the Nippon Foundation-GEBCO Seabed 2030 project's regional centers; they often catalog unpublished survey data. You should also directly contact the Tanzania Fisheries Research Institute (TAFIRI) and the University of Dar es Salaam's Department of Aquatic Sciences they sometimes have local datasets. As a last resort, I've had success filing collaborative data requests with the vessel operators of academic cruises (e.g., past RV Meteor or RV Sonne expeditions) that transited the area, offering co-authorship in exchange for the data.
