Evaluating multi-satellite chlorophyll-a datasets an ocean colour case study within the Southern Benguela
… GlobColour projects against a regionally tuned Sentinel-3 product within the Southern Benguela region. The three products were assessed against a collated database of coincident in situ chl-a matchups to derive a series of performance metrics. The regionally tuned Sentinel-3 product outperformed …

Quantifying phytoplankton biomass and sediment in river plumes along the Agulhas Bank using remotely sensed data with deep learning techniques
… sensing reflectance (Rrs) derived from standard Sentinel-3 Level-2 files, as well as two alternative approaches to AC, namely the Case-2 Regional CoastColour (C2RCC) processor, and the POLYnomial-based for MERIS (POLYMER). Thereafter, a regionally parameterised deep learning neural network …

The gulf of cadiz as a natural laboratory for the validation and exploitation of coastal altimetry and model data
… data, sea level altimetry measurements from Sentinel-3 SRAL, and observations from a hydrodynamic model implemented in the main study area. The in-situ data were used to validate the altimetry measurements, as well as to calibrate and validate the numerical model. Different specific …

The use of operational harmful algal bloom monitoring systems in South Africa to assess long term changes to bloom occurrence & impacts for aquaculture
… 16 years of MODIS-Aqua (1 km) and one month of Sentinel-3 OLCI (300 m), using regionally optimised blended algorithms, were used to investigate the spatial distribution and temporal variability of chlorophyll-a (Chl-a) along the south coast of South Africa. A Chl-a threshold of 27 mg m−3 was …

Towards high fidelity mapping of global inland water quality using earth observation data
… retrievals for small water bodies using Sentinel-3 Ocean and Land Color Imager (OLCI). Multiple fieldwork campaigns were undertaken for the collection of common aquatic biogeophysical and bio-optical parameters that were used to validate current atmospheric correction and chlorophyll-a …
