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 a= rea - would help with assessing change in ocean climate on a regional basis= that would be reflected in environmental effects monitoring (EEM) data aro= und the operation without causal linkage; i ncludes index of seasonal and inter-annual variations of = summer upwelling |
What are your actual limitations and do y= ou have a work around? |
To detect timing and extent of upwelling would require ext= ensive ship surveys which are time consuming and expensive |
Needs and expectations on EO data<= /p> |
Satellite imagery to detect upwelling features such a prod= uctivity, SSH, temperature |
