|Fig. 1 Ice Sheet Fingerprints|
In today's post let's take a look at WOD Zone 1110 and WOD Zone 1112, orienting ourselves by noting that Zone 1110 contains all or part of Laos, Vietnam and Cambodia, while Zone 1112 contains the Philippines.
For data quality purposes, as we did in the previous posts, we first note any aberrations in the data before and after correction (Fig. 3a and Fig. 3b).
On with the show.
|Fig. 2 WOD Zones|
On the graphic showing the sea level change impacts of Greenland and Antarctica (Fig. 1), the two zones are located in the upper right square.
The two zones are pointed to by two arrows at the lower left corner of that upper right square on each graphic (left side = Greenland; right side = Antarctica) on Fig. 1.
The Fig. 1 color graphic which originated in the paper, which I have mentioned previously in this series (Tamisiea, M.E., and J.X. Mitrovica. 2011, Oceanography PDF), indicates that Greenland has the larger impact on Zone 1112 because as concerns Greenland impact (left hand side of Fig. 1) the Philippines are in a brown zone, which indicates the second highest sea level rise impact area.
On the other hand, Laos, Vietnam, and Cambodia are in Zone 1110, which is located in the yellow colored area on both the Greenland and Antarctica impact graphic maps, indicating a more even handed sea level change impact from the ice sheets.

|Fig. 3b Zone 1110 Aberrant data|
That is because the Zone 1110 pattern or fingerprint (Fig. 3a) shows Greenland and Antarctica swapping places (higher, lower) from time to time.
In some years Greenland will have the most sea level change impact, but in other years Antarctica will.
In recent years it ends with them close to equal in terms of impact.
On the other hand Zone 1112 (Fig. 4) being in the second highest Greenland impact area (brown color, left side of Fig. 1) is impacted more by Greenland.
In recent years the Zone 1112 fingerprint pattern also shows more of a separation between Greenland influence and Antarctica influence, with Greenland winning out.
We have now covered six of the ten zones featured in this series.
This might be a good time to review the video of Professor Mitrovica concerning the relocation and distribution patterns of ice sheet melt water around the globe (The Ghost-Water Constant, 2, 3, 4, 5, 6, 7, 8, 9).
The previous post in this series is here.
Dr. Mitrovica video:
08:00 The use of global mean average has led us astray for 100 years.
15:20 Taking the average assumes the imaginary bathtub model.
16:30 It is completely wrong.
21:00 100m of SLF @ Greenland's coast when all ice sheet is gone.
26:40 The Dutch government did not understand the scenario.
28:40 When the ice sheet melts, all the water is distributed in 2 weeks.
29:30 It is error to say that SLF is due only to the land rising.
