Intern:Sample

The Sample table may be used for an internal administration of sampling (activity) related to material as defined in the event table. Use the

import form for upload. Information in the sample table is not visible on the Internet. Description of the fields as follows:
 * Label automaticaly produced by the system from the event label and an increasing index
 * SampleType: relational to the table SampleType with predefined types of scientific investigations
 * IDofSampleType should be used when importing lists of samples
 * Samples number of samples taken for a sequence
 * Quantity size of each sample in [ccm]
 * Year when the sampling was performed
 * Archive location: gives the place where the samples are stored; choose from available entries or add as free text
 * Storage popup list of climatic conditions in repository facilities
 * Processing multiple choice list of persons responsible for the samples; relational to staff
 * Comment for free internal use

For import in 4D choose File/Import, select Samples and open the list. A requester may come up sometimes, if a sample set already exists. Answer as appropriate. At the end of an import procedure, a log file is shown with information about the import process.

Major research programmes (e.g. ODP) use a well defined sample designation, ensuring the reconstruction of any analytical value to its original location in the core. ODP identifies cores, sections and samples by a sequence of numerals (examples are given in brackets):
 * Core: leg number + site number + hole letter + core number + core-type letter (Core 101-626A-2R)
 * Section: leg number + site number + hole letter + core number + core-type letter + section number (Section 101-626A-2R-1)
 * Core catcher: leg number + site number + hole letter + core number + core-type letter + core-catcher abbreviation (Sample 101-626A-2R-CC)
 * Sample: leg number + site number + hole letter + core number + core-type letter + section number + interval from top of section in cm (Sample 101-626A-2R-1, 50-52 cm)
 * In data tables sample designations occur without identifier and unit (113-693A-4R-3,23-25). This standard ODP sample designation should accompany each record in a data file ! See also the link to ODP sample designation in the method table.

Core-type letters used:
 * R = rotary core barrel (RCB);
 * X = extended core barrel (XCB);
 * H = hydraulic piston corer (HPC), also advanced piston corer (APC);
 * B = drill-bit recovery;
 * C = center-bit recovery;
 * I = in-situ water sample;
 * S = sidewall sample;
 * W = wash-core recovery;
 * V = vibropercussive corer (VPC);
 * M = miscellaneous material

Unique Identification: The problem of non-unique sample names was addressed by the global earth science community. Currently, the only available system where individuals can obtain global unique identifiers for their samples is the sample registry SESAR (System for Earth Sample Registration, www.geosamples.org). The unique identifier provided and administered by SESAR is the 9-digit alphanumeric International Geo Sample Number (IGSN), which is used together with a person’s or institution’s sample name to ensure unambiguous identification of a sample. IGSNs can be obtained from SESAR by submitting the information about a sample.
