 Coastal upwelling

Challenge ID



Coastal upwelling

Challenge originator:


General Description


What data/products do you use?

Ship-based measurements; satellite images

When do you use this kind of dataset?

To determine timing and magnitude of productivity in the area - would help with assessing change in ocean climate on a regional basis that would be reflected in environmental effects monitoring (EEM) data around the operation without causal linkage;  i ncludes index of seasonal and inter-annual variations of summer upwelling

What are your actual limitations and do you have a work around? 

To detect timing and extent of upwelling would require extensive ship surveys which are time consuming and expensive

Needs and expectations on EO data

Satellite imagery to detect upwelling features such a productivity, SSH, temperature
