Climate observations prior to the instrumental era are necessarily indirect. These observations are made on climate proxies in various geological (e.g. lake or marine sediments, living or fossil coral reefs, cave deposits), glaciological (ice cores or snow pits) or biological (trees) archives. Many types of measurements can be made on each archives, each sensing a different aspect of the environment (sometimes, several aspects at once). A paleoclimate dataset is a set of observations made on an archive.

Climate observations prior to the instrumental era are necessarily indirect. These observations are made on climate proxies in various geological (e.g. lake or marine sediments, living or fossil coral reefs, cave deposits), glaciological (ice cores or snow pits) or biological (trees) archives. Many types of data can often be collected from each archives, each sensing a different aspect of the environment (sometimes, several aspects at once). A paleoclimate dataset is almost always a <a rel="nofollow" class="external text" href="https://en.wikipedia.org/wiki/Time_series">time series</a> of observations made on an archive. Evans et al. (2013) <a href="#cite_note-evans2013-1">[1]</a> define a proxy system as comprised of three components (Fig 1).: <ul><li> The <a href="#ProxySensor" title="Category:ProxySensor"> sensor</a> comprises physical, chemical, and/or biological components that react to environmental conditions. Sensors often respond to more than one environmental <a href="#InferredVariable" title="Category:InferredVariable"> variable</a>, and may have complex responses to the environment they sense, including thresholds (record only part of the range of environmental conditions), seasonal biases (record environmental conditions over a few months of the year), and/or nonlinear responses. For instance, <a href="#Foraminifera" title="Category:Foraminifera"> foraminifera</a> are an often used sensor for oceanic conditions. Multiple observations can be made on this sensor, recording different environmental <a href="#InferredVariable" title="Category:InferredVariable"> variables</a>. Similarly, picking foraminifera of a given species to conduct the measurements is part of the observation process, though it does affect the sensor definition : the habitat of these forams determines with environmental <a href="#InferredVariable" title="Category:InferredVariable"> variable</a> (e.g. surface, sub-surface, or thermocline temperature) they are most sensitive to. </li></ul> <ul><li> The <a href="#ProxyArchive" title="Category:ProxyArchive Â©"> archive</a> is the medium in which the response of a sensor to environmental forcing is recorded. Marine sediments are a type of archive, on which many sensors and observations may be recorded (e.g. Foraminifera Mg/Ca, Î´18O, TEX86)</li></ul> <ul><li> <a href="#ProxyObservation" title="Category:ProxyObservation"> Observations</a> are made on archives and are generally referred to as "proxies". The term "proxy" used ubiquitously, and often ambiguously, throughout the paleoclimate literature, is most commonly equivalent to "sensor + observation". "Observation" is the more explicit, and thus, preferred term, however "proxy" can be treated as a synonym of "observation". For instance, Foraminifera Mg/Ca is often used to investigate past changes in sea-surface temperature but depends also on sea-surface salinity and deep-ocean carbonate saturation <a href="#cite_note-2">[2]</a>. Furthermore, its temperature and salinity dependence is exponential <a href="#cite_note-3">[3]</a> <a href="#cite_note-4">[4]</a> <a href="#cite_note-5">[5]</a> while its response to carbonate saturation is thresholded <a href="#cite_note-6">[6]</a>. </li></ul> These three major components may be individually modeled, and linked together within a <a href="/Category:ProxySystemModel_%C2%A9" title="Category:ProxySystemModel Â©">Proxy System Model</a> <a href="#cite_note-evans2013-1">[1]</a> <a href="#cite_note-7">[7]</a>. Some sensors are common to multiple archives (e.g. Î´18O), and all archives support more than one possible sensor. <h2>References</h2> <ol class="references"> <li id="cite_note-evans2013-1">â†‘ <a href="#cite_ref-evans2013_1-0">Jump up to: 1.0</a> <a href="#cite_ref-evans2013_1-1">1.1</a> <a href="#cite_ref-evans2013_1-2">1.2</a> Evans, M.

In regions with large seasonal variations, trees produce rings of varying color depending on the species. In most cases, the rings shift from a lighter, low density early wood of spring and early summer to a darker, denser band of late wood at the end of the growing season. The growing season generally occurs during the summer month and its length depends on the species, latitude, and altitude. Therefore, trees hold perhaps the greatest potential for reconstructing past terrestrial climates at annual or even sub-annual resolution.

Oxygen has three naturally-occuring stable isotopes: 16O, 17O, 18O, with 16O being the most abundant (99.762%). Two international reference standards are used to report variations in oxygen isotope standards: PDB and SMOW. The use of the PDB standard in reporting oxygen isotope composition is restricted to carbonates of low-temperature origins (e.g., oceanic, lacustrine ). The conversion between SMOW and PDB scales is given by: \delta^{18}O_{SMOW} = 1.03091 (\delta^{18}O_{PDB}) +30.91 Î´18O may be measured on the shells of foraminifera

TEX86ⁿⁱ back to ToC or Named Individual ToC

IRI: http://linked.earth/ontology#TEX86

The use of TEX86 (TetraEther indeX of 86 carbons) as a tool to reconstruct past sea surface temperature variability is based on the relative cyclization of isoprenoidal glycerol dialkyl glycerol tetra ethers (GDGTs) produced by marine archaea. TEX86 is defined as [1]: TEX_{86}=\frac{GDGT-2+GDGT-3+Cren'}{GDGT-1+GDGT-2+GDGT-3+Cren'} where GDGTs 1-3 indicate compounds containing 1-3 cyclopentyl moieties, respectively, and Cren' denotes the regioisomer of crenarchaeol, a diagnostic biomarker for the Thaumarchaeota, the primary producers of GDGTs in the marine realm. By definition, values of the TEX86 index are comprised between 0 and 1. Experimental evidence suggests that archaea produce GDGTs with more rings warmer waters, a response observed in cultures of hyperthermophile archaea [2] [3] and mesocosm experiments with natural seawater containing heterogenous archaeal population [4] [5].

The currently accepted U37kprime (Prahl and Wakeman, 1987) varies positively with temperature, and is defines as C(37:2)/(C(37:2)+C(37:3), where C(37:2) represents the quantity of the di-unsaturated ketone and C(37:3) the quantity of the tri-unsaturated form.

Uk37ⁿⁱ back to ToC or Named Individual ToC

IRI: http://linked.earth/ontology#Uk37

The C37 alkenone unsaturation index ( U_{37}^{k'} ) is a firmly established tool for past sea surface temperatures reconstruction and is based on the relative abundance of di- (C37:2) and tri- (C37:3) unsaturated ketones with 37 carbon atoms. The index varies between 0 and 1, thus it may saturate in the temperature extremes as it becomes more challenging to determine since C37:3 and C37:2 alkenones approach their detection limits. Since alkenones come exclusively from a few species of haptophyte algae which require sunlight, alkenone thermometry offers the advantage of direct estimate of near-surface ocean temperatures. The ubiquitous presence of alkenone-synthesizing organisms (most commonly the coccolithophorids Emiliania huxleyi and Gephyrocapsa oceanic through the world's ocean and the rapidity and high-precision of the alkenone analyses had made U_{37}^{k'} a valuable proxy for paleoceanographic reconstructions. However, the U_{37}^{k'} proxy is subject to non-temperature effects, such as lateral transport through oceanic currents (Ohkouchi et al. (2002)) and preferential post-depositional oxidation of C37:3 compared to C37:2 [1] [2]. Furthermore, changes in the seasonality of the proxy (i.e., which part of the seasonal cycle the proxy is recording) may bias the inferred temperatures toward winter or summer conditions [3]. Finally in oceanic regions where the photic zone extends below the surface mixed layer, the sedimentary signal may not strictly represent sea surface temperatures but rather a composite temperature of the mixed layer and the thermocline [4][5].
