in their response, attempt to refute our conclusions and claim the deposits to be the result of a +21
m eustatic sea level highstand during marine isotope stage (MIS) 11.
Satellite measurements of the Patagonian icefields suggest that they are currently rapidly receding and thinning, with a measureable contribution to
eustatic sea level rise2.
17,000 - year glacio -
eustatic sea level record: influence of glacial melting rates on the Younger Dryas event and deep - ocean circulation.
Note that these trends may include a component of subsidence / uplift of the islands themselves and so are the numbers most relevant for local planning (
not eustatic sea level change).
Cross-cutting relationships are observed at the valley - scale, indicating multiple episodes of water level fall and rise, each well over 50 meters, a similar scale to
eustatic sea level changes on Earth.
On Earth, incised valleys are commonly cut and filled during falling and rising
eustatic sea level, respectively.
C: Datasets suggesting a drying environment at 2.5 Ma, shown by λ 18O from benthic foraminifera, a proxy for global temperature, smoothed with a Gaussian window of 200 ky;
eustatic sea level; and magnetic susceptibility, a proxy for ice rafted debris and Northern Hemisphere glaciation.
My point in bringing this up is that 99.99 % + of
the eustatic sea level changes have occurred prior to mans existance.
