New Type of SLC Detection Model - 13

Fig. 1 Mean Avg. SLC of 34 PSMSL Stations
A while back I did a post concerning the sea level change (SLC) at various  tide gauge stations along the East Coast of the United States.

Those stations are registered at the Permanent Service for Mean Sea Level (PSMSL) which is held in high esteem by scientists doing SLC work (New Type of SLC Detection Model - 5).

Today I want to revisit all or most of them in a combined way, which is to say "a mean

average SLC" of those stations.

But more than that, I want to do so in both the traditional PSMSL way (Fig. 1), and also the new Dredd Blog "SLC fingerprint" way (Fig. 2).

That is, we combine all records from 1856-2014 into a mean average SLC fingerprint composed of the data from the 34 tide gauge stations listed below (Fig. 1, Fig. 2).

The stations used in this project today are presented in "Name (#number)" format (by ascending latitude of 23-46 deg. N; and longitude of 66-80 deg. W):

ST. GEORGES / ESSO PIER (BERMUDA) (#368)
CHARLESTON I (#234)
SPRINGMAID PIER (#1444)
WILMINGTON (#396)
DUCK PIER OUTSIDE (#1636)
SEWELLS POINT @ HAMPTON ROADS (#299)
CHESAPEAKE BAY BR. TUN. (#1635)
KIPTOPEKE BEACH (#636)
SOLOMON'S ISLAND (BIOL. LAB.) (#412)
CAMBRIDGE II (#1295)
LEWES (BREAKWATER HARBOR) (#224)
WASHINGTON DC (#360)
CAPE MAY (#1153)
ANNAPOLIS (NAVAL ACADEMY) (#311)
BALTIMORE (#148)
ATLANTIC CITY (#180)
REEDY POINT (#786)
PHILADELPHIA (PIER 9N) (#135)
SANDY HOOK (#366)
NEW YORK (THE BATTERY) (#12)
MONTAUK (#519)
BRIDGEPORT (#1068)
NANTUCKET ISLAND (#1111)
NEW LONDON (#429)
NEWPORT (#351)
WOODS HOLE (OCEAN. INST.) (#367)
PROVIDENCE (STATE PIER) (#430)
BOSTON (#235)
PORTLAND (MAINE) (#183)
YARMOUTH (#1158)
BAR HARBOR @ FRENCHMAN BAY @ ME (#525)
HALIFAX (#96)
EASTPORT (#332)
SAINT JOHN @ N.B. (#195)

Each site in the list above is linked to its PSMSL site web-page (Use Permanent Service for Mean Sea Level to look up any other tide gauge stations by searching on station name or tide gauge station number).

What we learn from this Dredd Blog software model enhancement is:
1) not only single tide gauge stations can be fingerprinted (additional areas with similar SLC characteristics can be properly fingerprinted together as a group to produce a group fingerprint);

2)  Antarctica has the most SLC influence on the 34 stations along the East Coast (U.S. & Canada @ 23-46 deg. N Latitude; @ 66-80 deg. W longitude);

3) Antarctica has been melting longer than previously thought.
(Watch The Ice Shelves - 2). The Dredd Blog software model is turning out to be versatile and useful in several ways.

By using verifiable historical data as a foundation, the model is better prepared to generate future projections.

    We were worse than previously thought.
