Hybrid Coordinate Ocean Model (HYCOM) EnOI Version 1.1 Raw (L3R) Regional Agulhas 10km Ocean State Estimate 2009

The greater Agulhas Current is one of the most energetic current systems in the global ocean. It plays a fundamental role in determining the mean state and variability of the regional marine environment, affecting its resources and ecosystem, the regional weather and the global climate on a broad range of temporal and spatial scales. In the absence of a coherent in-situ and satellite-based observing system in region, modelling and data assimilation techniques play a crucial role in both...

Cape Canyon Suspended Particulate Matter CTD water sample

The Cape Canyon, situated on the western continental shelf of South Africa, stands as the country's largest bathymetric feature. Despite its prominence, understanding of the food web dynamics within the system and the significance of the benthic community for higher trophic levels remains incomplete. In response to this knowledge gap, the DFFE: Oceans and Coasts launched a multidisciplinary expedition aboard the RV Algoa. The expedition aimed to characterise the physical environment and...
