Title: Global-Scale Links with Local-Scale


1
Global-Scale Links with Local-Scale
  • Two-Way Interactions
  • Global ocean and climate dynamics strongly
    influence processes at local scales (and vice
    versa), particularly in coastal regions

kms hours to weeks
100-km years
In a nonlinear, coupled system, scales are linked.
1000-km, decades
2
Coastal Zones Dynamic, Interfacial Regions
Coastal zones are dynamic regions, at the
interface of land, sea and air. They also are
typically heavily populated and often urbanized.
There is frequent exchange of energy and matter
across boundaries, with humans impacting the
ocean and vice versa.

level question(s) Habitats, Hazards,
Ecosystems Key issues Imagery with spatial
resolution of meters or less is critical for
mapping and tracking fine-scale features along
coastal margins, including river plumes, flooded
land regions, and seafloor features. Hazardous
and episodic events require repeat sampling on
the order of hours and not days or weeks, and
require an imaging platform that can be used
under cloud cover. Diel processes require
high-freq repeat observations.
