Suspended Sediments 645nm 856 nm
Sediment Resuspension • Pollution plumes • Water quality in beaches • Sediment transport • Models
The same analysis is possible for POC and PIC transport – easier with Hyper-GEO • Problems: • Need to use weekly and monthly composites. • Cannot resolve tidal cycles • CDOM retrievals • Atmospheric corrections • Photobleaching
CO2 + CO + LMWC CDOM + Light bugs CO2 + etc LMWC +O2 CO2 0.2 to 4 Pg C y-1 Global Photoproduction: CO 0.1 to 1 Pg C y-1 upwelling
HABS • Discrimination between HABS and non-HABS blooms • Monitoring of Blooms • Research • Models FERI SAMSON data from C. Davis and P. Bissett. Akashiwo sanguinea
LEO sensors cannot: • Resolve tidal influences • Diel winds • Coastal jets
South Atlantic Patagonia Tropical instability waves
Conclusions • Ideal for coastal • Not limited to coastal • Not limited to NA • Lunar calibrations • Vicarious calibration • Support of field work • Process studies • Special events • Support Models Earths view from -90o longitude Equatorial plane
