stratigraphic

The problem is that we only have direct measurement data from the late 19th century forward; prior to that, the data is inferential, deduced from ice cores, tree rings, sedimentation, and other techniques, which are largely stratigraphic, and which do not render precise thermography data.

There are scientists actively trying to persuade their peers that this isn't just an esoteric notion, the stuff of environmental conferences, but a stratigraphic fact, a real geological divider every bit as real as the Permian-Triassic boundary or anything else in the record.

The sinuous patterns that you see on the sides of these modeled landscape correspond to actual stratigraphic markings in the real world — earth's own hieroglyphs that can be read and interpreted, allowing one to piece together a biography.

Since a few cites identify the original quote-tablet as "Babylonian" instead, I suspect that this one was mixed in from a much later stratigraphic layer from the 6th century BC.

Whether to formalize the Anthropocene or not is a question that will be decided on geological, and, more precisely, stratigraphic grounds.

"If you could stand there, you would see this beautiful formation of Martian sediments laid down in the past, a stratigraphic section that's more than twice the height of the Grand Canyon, though not as steep," said Bradley Thomson of the Johns Hopkins University Applied Physics Laboratory, Laurel, Md.

However, a general lack of precise absolute timescales and regionally-to - globally synchronous stratigraphic markers makes long-distance correlation between sites problematic, and inferred terrestrial changes are difficult to place within the temporal framework of changes in ice volume and sea level [24].

Arctic climate variability prior to 100 years BP 2009

Given the inherent errors in dating techniques, gaps in the stratigraphic record, and the varying rates of response of different biological proxy indicators, there is considerable uncertainty about the timing of specific events and whether climate changes were truly synchronous in different regions.
