Coastal
mountains in Alaska's active margins offer an
|
|
exceptional
and largely untapped opportunity to
|
|
measure
and to understand rates of erosion from both
|
|
glaciated
and non-glaciated terrains
|
|
|
|
– |
rates are high
(relief and precipitation are both high and bedrock
|
|
is damaged)
|
|
|
|
– |
fjords are nearly perfect sediment traps
for both suspended
|
|
|
sediment and
bedload.
|
|
|
|
– |
seismic profiles
together with retreat history can be used to infer
|
|
sediment yield
history for ~100 years
|
|
|
|
– |
sediment sources are close to sinks and
storage is minimal
