In order to predict the impacts of climate change induced sea-level rise
on Pacific Northwest coastal habitats, the Sea Level Affecting Marshes
Model (SLAMM) was utilized to simulate future coastal habitat
configurations under various sea-level rise scenarios. The model was run
for 2025, 2050, 2075, and 2100. Historical or "initial
condition" habitat classifications are also available for some
sites. The sea-level rise scenarios include:
1. A1B greenhouse gas
emission mean : 0.39 meter rise by 2100
2. A1B greenhouse gas
emission maximum : 0.69 meter rise by 2100
3. 1 meter rise by 2100
4. 1.5 meter rise by 2100
5. 2 meter rise by 2100
Due to differing site
conditions, local sea-level rise varies slightly from these figures, and
the exact sea-level rise used by the model for each site can be found on
page 29 of the report linked below.
This dataset includes
data for a portion of site 11, and it covers the Columbia River estuary.
