PaleoceanOxygenIsotopes.getAverageSedimentationRates(startyear: Number?, endyear: Number?)

Get average sedimentation rate value (unit: centimeter per kiloyear).

If startyear or endyear is provided, only measurements within the given range will be returned.

Arguments:

  • startyear: Number? info - first year of data to include
  • endyear: Number? info - least year of data to include

Returns: List info - a list of average sedimentation rate by year

PaleoceanOxygenIsotopes.getDelta18O(startyear: Number?, endyear: Number?)

Get delta 18O value (unit: per mill. It is a parts per thousand unit, often used directly to refer to isotopic ratios and calculated by calculating the ratio of isotopic concentrations in a sample and in a standard, subtracting one and multiplying by one thousand).

If startyear or endyear is provided, only measurements within the given range will be returned.

Arguments:

  • startyear: Number? info - first year of data to include
  • endyear: Number? info - least year of data to include

Returns: List info - a list of delta 18O values by year

PaleoceanOxygenIsotopes.getDelta18OError(startyear: Number?, endyear: Number?)

Get delta 18O error value (unit: per mill).

If startyear or endyear is provided, only measurements within the given range will be returned.

Arguments:

  • startyear: Number? info - first year of data to include
  • endyear: Number? info - least year of data to include

Returns: List info - a list of delta 18O error values by year

PaleoceanOxygenIsotopes.getNormalizedSedimentationRates(startyear: Number?, endyear: Number?)

Get normalized sedimentation rate value (unit: dimensionless).

If startyear or endyear is provided, only measurements within the given range will be returned.

Arguments:

  • startyear: Number? info - first year of data to include
  • endyear: Number? info - least year of data to include

Returns: List info - a list of normalized sedimentation rate by year
