artemisia pollen Data

At present IPOL holds site metadata for published records and academic theses but does not include unpublished reports. We would like to add these to the database. Please let me know of reports and other pollen work that I may not be aware of. Contact email: bstefanini@ipol.ie

While I have taken care to check reference material against OS maps and original publications, there may be some errors in the dataset. Please notify me if you come across mistakes.

The site table

Records have to have at least three pollen samples to be included in IPOL.

Site numbers

These are unique and link the replica watches sale Google earth markers with the site table. Sites are not in any particular order.

Site names

Site names are not unique. Where the same site name is used for different locations, a geographical identifier is panerai replica uk added to the name, e.g. Red Bog (Louth). If the same site was investigated several times a number is added to the name e.g. Treanscrabbagh1 and Treanscrabbagh2.

Altitude

Altitude above mean sea level is as reported in the publication or read from the OS maps.

Site coordinates

These are in latitude and longitude, they can also be read from the properties of the Google earth site markers. To change coordinate formats you replica watches uk may want to use the coordinate converter of the OSI or Barry Hunter's nearby converter.

Multiple cores

Many site entries contain records of several cores or of sites in close proximity. Unless they are different site types or appear in swiss replica watches different publications, sites investigated within one area by the same team of researchers are generally represented by only one entry. They are marked as multiple cores.

Site type

Describes the site.

Time span

The database includes an approximate time span covered by the records. This parameter is no more than a loose estimate from the pollen diagrams. Please check the original publications for dates.

Dates

Dates are in calPB, that is calibrated radiocarbon years before AD1950. No distinction is made between conventional and AMS 14C dates. Where several cores exist, the 'number of dates' generally refers to the core with most dated levels.

Analyst

The person who enumerated and identified the pollen.

References

The reference is not always for the earliest publication but may be the publication which is easiest to access. Early pollen work was often reported separately from associated 14C dates. Where I found separate records for the pollen and the dates, I included both papers. The references are also included in the 'Properties' of the Google earth site markers.
