What is the LR04 benthic stack?
[7] The LR04 stack contains 57 benthic records aligned using a graphic correlation technique [Lisiecki and Lisiecki, 2002] and is the first benthic δ18O stack containing more than three records to extend beyond 850 ka.
What is LR04?
The LR04 stack [Lisiecki and Raymo, 2005] spans 5.3 Myr and is an average of 57 globally distributed benthic d18O records (which measure global ice volume and deep ocean temperature) collected from the scientific literature.
What is a sea MIS?
Marine isotope stages (MIS), marine oxygen-isotope stages, or oxygen isotope stages (OIS), are alternating warm and cool periods in the Earth’s paleoclimate, deduced from oxygen isotope data reflecting changes in temperature derived from data from deep sea core samples.
What MIS 3?
Marine Isotope Stage (MIS 3), dated 60–27 ka (BP), is characterised by extremely high climate instability, as evidenced by its rapid and high-frequency changes. Its record has already been documented in Greenland and Antarctic ice cores (Siddall et al., 2008; Van Meerbeeck et al., 2009, 2011; Railsback et al., 2015).
What MIS 2?
MIS 2 – 29. MIS 3 – 57 (MIS 2-4 is called the Last Glacial Period, Wisconsinan glaciation in North America, Weichselian glaciation in northern Europe) MIS 4 – 71. MIS 5 – 130, usually sub-divided into a to e: MIS 5a – 82 (peak of interglacial sub-stage)
Is TPS part of MIS?
TPS becomes a major source of data for MIS. The data that is generated through TPS is on the level of operations such as payroll or order processing. TPS tracks daily routine transactions that are essential to conduct business.
What are the main types of MIS?

Is Earth in an interglacial period?
We are in an interglacial period right now. It began at the end of the last glacial period, about 10,000 years ago. Scientists are still working to understand what causes ice ages. One important factor is the amount of light Earth receives from the Sun.
What is the difference between a glacial and interglacial period?
During an ice age, a glacial is the period of time where glacial advancement occurs. Similarly, an interglacial or interglacial period is the warmer period of time between ice ages where glaciers retreat and sea levels rise.
What is DSS and TPS?
A major difference between TPS and DSS is the general purpose of each type of system. TPS are designed to expedite and automate transaction processing, record keeping, and simple business reporting of transactions. DSS are intended to assist in decision making and decision implementation.
What are the 5 types of MIS?
How many benthic records are in the LR04 Stack?
[7] The LR04 stack contains 57 benthic records aligned using a graphic correlation technique [ Lisiecki and Lisiecki, 2002] and is the first benthic δ 18 O stack containing more than three records to extend beyond 850 ka.
What is the error bar on the LR04 Stack?
The stack spans the entire Pliocene-Pleistocene with error bars averaging only 0.1‰. We also use the LR04 stack to develop a conservatively tuned δ 18 O timescale, which minimizes deviations in globally averaged sedimentation rates.
What are the stages in the LR04 Stack?
The stages which are unusually small or poorly defined in the LR04 stack are MIS 68, 69, 79, 80, 94, 102, G5, G8, G9, K2, and KM6. [34] Below the Mammoth subchron, the LR04 stack reduces noise in some portions of the record to the extent that new isotopic stages can be resolved.
What is the difference between the SPECMAP and LR04 age models?
The variance of the SPECMAP stack is only 60% that of the LR04 stack from 0–625 ka. The low resolution of SPECMAP records and the smoothing performed on the final stack probably played a large role in reducing SPECMAP variance. The SPECMAP and LR04 age models typically differ by less than 6 kyr since 625 ka ( Figure 11 ).
