Sea Level Variations of the United States, is now available on the NOAA website http://tidesandcurrents.noaa.gov Linear sea level trends are provided for 117water level stations of the NWLON For each station, the sea level trend, standard error, the average seasonal cycle are provided

Slide14: 

Expand 117 U.S. NWLON stations to include 44 none U.S. GLOSS sea level reference stations (total of 62 GLOSS stations) Sea Level Trends Product Enhancement

Sea Level Variability: 

Sea Level Variability Sea level variations showing monthly ocean fluctuations are displayed (long term sea level trend and annual seasonal cycle removed)

Comparison of Sea Level Trends: 

Comparison of Sea Level Trends The comparison of Sea Level Trends displays the regional variability of relative sea level change.

Monthly Sea Level Anomalies: 

Monthly Sea Level Anomalies These plots reflect the oceanographic conditions in the coastal ocean that affect water levels and identify their impacts on coastal areas such as the 1997-1998 El Niño and the 2000-2002 La Niña. .

Slide18: 

NOAA has operated a tide station in cooperation with JPL/NASAon Platform Harvest since 1992 in support of TOPEX/Poseidon and Jason-1 providing data for altimeter evaluation and closure analyses. Satellite Altimeter Mission Support

Variations in Annual Mean Sea Level at San Francisco 1856-1999 Linear Trend: +0.09 in/yr Mean Sea Level Has Risen About 4.4 Inches Relative To The Land Since 1950 Elevation Relative to Station Datum (feet) 1983-84 el Niño Event PROBLEM: Assessing and Forecasting the Impacts of Relative Sea Level Rise on Coastal Communities

http://www.climatescience.gov/: 

Question: What are the current and potential future impacts of global environmental variability and change on human welfare, what factors influence the capacity of human societies to respond to change, and how can resilience be increased and vulnerability reduced? Deliverable: Elevation maps depicting areas vulnerable to sea level rise and planning maps depicting how state and local governments could respond to sea level rise.

Building the National Backbone: A Key Federal Role: 

“End-to-End” Built through local, regional and national partnerships Provides real-time and archival data for a core set of parameters Supplies data to meet national and regional resource management needs National Water Level Observing Network – an example of a Backbone component The national backbone provides the observational density, timeliness and locations sufficient to detect and predict changes in environmental parameters at a national scale. Data from the national backbone can be used at all scales, but most importantly supplies the essential information for national policy formulation Building the National Backbone: A Key Federal Role U.S. Contributions to the Integrated Ocean Observing System (IOOS)
