Record 2 2012-03-01

English

Subject field(s)
  • Climate Change
DEF

Data obtained from a wide range of biological, geological and geophysical phenomena: ice-cover ocean cores micro-fauna and isotopes, tree rings, lake varves, pollen records.

CONT

Proxy data can take a number of forms, some of which are extremely accurate. For example, air pockets trapped in ice cores can provide a record of atmospheric gases dating back thousands of years. As well, trees produce annual rings which vary in response to different climatic effects. By studying the ring record in old trees, an annual climatic record can be deduced.

French

Domaine(s)
  • Changements climatiques
DEF

Données climatologiques obtenues à partir de données non météorologiques, par ex. : observations des anneaux de croissance des arbres, etc.

OBS

L'indicateur permet d'obtenir, généralement par déduction, des données sur des phénomènes climatiques qui, dans la pratique, ne peuvent être, ou ne peuvent plus être, mesurés directement; les connaissances actuelles du phénomène de réchauffement climatique, les restitutions climatiques particulièrement, reposent en grande partie, à cause des lacunes importantes dans les données nécessaires pour une compréhension globale de ce phénomène, sur des mesures indirectes fournies par des indicateurs (par ex. les cernes de croissance des arbres fournissent des données indirectes sur la quantité de précipitations avant les premières observations par instrument).

OBS

Le déterminant «substitutif» est surtout utilisé en statistique.

Key term(s)
  • donnée indirecte
  • donnée substitutive
  • donnée de substitution

Record 3 2012-03-01

English

Subject field(s)
  • Climate Change
DEF

Any material that provides an indirect climate measure and includes documentary evidence of harvest dates, glacier movements, tree remains, marine microfaune, and isotope measurements including oxygen 18 in ice sheets, carbon 13 in tree rings, and CaCO3 in sediments and speleothems.

CONT

Paleoclimate studies using AMS [Accelerator Mass Spectrometry] radiocarbon ... During the past several years, AMS measurements have increasingly supplanted the traditional counting method of dating since they offer greatly increased sensitivity (sub-milligram samples can be dated) and, in many instances, greater accuracy; they are also very much faster. However, the typical "bulk carbon" sample preparation techniques used for both AMS and ... counting leave unanswered the question of just what is being dated, a grave disadvantage in palynological and other paleoclimate studies. In contrast, the extraction procedures that have been developed here typically produce purified pollen samples which can be clearly identified under the microscope; thus, an unambiguous proxy climate indicator -pollen- is dated, and nothing else.

OBS

There are 3 main problems in using proxy data : dating, lag and response time, and meteorological interpretation.
