Age
Age is Older/Equal/Younger than - Select one option among those listed.
Marine Isotopic Stage - Select a MIS from the list. Add new MIS definitions if necessary. If the MIS is already present in the list but a different definition is needed, use the text box below (Comments/details on MIS designation).
Comments/details on MIS designation - Provide comments or details on the designation above.
Reported age (ka) - Reported age.
Reported age uncertainty (±2σ) (ka) - Reported age uncertainty. If the uncertainty level is not reported, note it in the textbox above. If reported to ±1σ level, transform to ±2σ.
Detailed sample and analysis information
Sample Type - Indicate whether marine/estuarine/freshwater mollusc or gastropod shell, foraminifer, or whole-rock sample.
Taxonomy - If known or applicable, provide at least the Genus. Description to the species level is beneficial.
Current Annual Mean Temperature (°C) - The mean annual temperature for the field location as determined from the national government bureau of meteorology or equivalent.
Collection Context - Brief description of taphonomic condition and depositional setting/sedimentary environment/facies; e.g. mollusc shell in live position, robust condition with little or no evidence of abrasion, in back-barrier lagoon sediments
Depth of burial (m) - Depth of burial below modern surface. If present, include proximity to over- or underlying diastems and/or unconformities. If unknown digit "unknown".
Preparation procedure - Reference to sample preparation procedure.
Method of chromatography - E.g. gas chromatography (GC), reversed-phase high-performance liquid chromatography (RP-HPLC), or ion-exchange chromatography high performance liquid chromatography (IEC HPLC). If unknown, digit "unknown"
Stationary phase of the column - Describe the stationary phase of the column.
Notes and comments on sample quality - Any additional notes concerning sample that may have impact of sample results.
Sample position - Indicate what portion of the shell was sampled, e.g. lip, hinge, etc.
Whole-Rock? - Indicate if the record refers to a whole-rock analysis. The following fields appear if "Yes" is selected above Grain Size (μm) Carbonate (%) Fraction (μm)
Number of replicates (samples)
Number of sample replicates (injections)
Ratio type - Was peak height or peak area reported?
Pyrolysis experiment available - Indicate if the results of a pyrolysis (isothermal heating) experiment are used in discussion of field sample results and reference publication
Reported Amino Acid D/L Values (THAA)
Level of uncertainty - Result uncertainty, e.g. 1σ or 2σ or N/A.
Amino Acid D/L values: Aspartic / Aspartic uncertainty Glutamic / Glutamic uncertainty Serine / Serine uncertainty Alanine / Alanine uncertainty Valine / Valine uncertainty A/I / A/I uncertainty Leucine / Leucine uncertainty
Notes/Comments - Any additional information that may be worthy of mention
The following selections define which fields must be filled next: Independent age constraints available? Calibration data available? Are free AAR ratios available?
Reported Amino Acid D/L Values (FAA)
This field is activated only if 'Yes' is selected in the 'Are free AAR ratios available? ' field
Level of uncertainty - Insert uncertainty, e.g. 1σ or 2σ or N/A.
Amino Acid D/L values: Aspartic / Aspartic uncertainty Glutamic / Glutamic uncertainty Serine / Serine uncertainty Alanine / Alanine uncertainty Valine / Valine uncertainty A/I / A/I uncertainty Leucine / Leucine uncertainty
Notes/Comments - Any additional information that may be worthy of mention
Calibration
This field is activated only if 'Yes' is selected in the 'Calibration data available?' field
Calibration method - Method for calibrating age. The most common approach is to subdivide a single sample, and analyze one subsample with AAR and the second with the complementary method.
Amino Acid age equation - If the D/L values are calibrated to provide an age, what equation is used.
Calibration laboratory - Laboratory where the age calibration was done.
Calibration laboratory ID - Original ID of the age calibration.
Calibration reference - Select a reference for the age calibration.
Calibration D/L value / Calibration D/L value uncertainty (±1σ) Calibration age (ka) / Calibration age (ka) uncertainty (±1σ)
Independent Age
This field is activated only if 'Yes' is selected in the 'Independent age constraints available?' field
Independent age choice - Select the independent age constraint available. Option will appear according to the selected value in this field.
The following selections appear depending on the choice made above:
Independent age method - Describe briefly the independent age determination methodology.
Independent age laboratory - Insert the name of the laboratory where the independent age has been obtained.
Independent age laboratory ID - Laboratory ID for the independent age.
Independent age result - Indicate here the independent age and associated uncertainties.
Independent age reference - Select a reference for the independent age.
Useries constraint - If a U-Series independent constraint is available, select the ID here.
ESR constraint - If an ESR independent constraint is available, select the ID here.
Luminescence constraint - If a luminescence independent constraint is available, select the ID here.
Stratigraphic constraint - If a stratigraphic independent constraint is available, select the ID here.
