General Information

Site name - Name of the site. This could be a local geographic name, or the name of the town/city where the site is located.

Subsite - Survey name or transect number assigned to the site. This may also include a sub-facies within the sea level sequence.

Nation - The nation where the site is located.

Region - The administrative region or province where the site is located.

Main reference - The main reference from which RSL information has been extracted. This is usually the reference describing the site and reporting measurement and dating details.

Additional References - Select further references describing the site. Ideally this field includes all the historical references reporting on the site.

Latidude (decimal degrees) - Latitude of the site, in decimal degrees.

Longitude (decimal degrees) - Longitude of the site, in decimal degrees.

Horizontal Positioning Technique - Define the positioning technique used to establish the site Lat/Long coordinates. New positioning techniques can be added as necessary, referring to the Geographic positioning table.

Is this a marine/terrestrial limiting record? - Indicate if the record inserted is a marine or terrestrial limiting, or a sea level indicator. The following fields will update accordingly. For a definition of marine/terrestrial limiting in MIS 5e, see Rovere et al., 2016¹. See Figure 1 for an example.

Type of RSL Indicator - Sea level indicator that was reported at the site. New indicators can be added from to the Type of RSL indicator table.

Elevation and Paleo RSL

Upper limit of modern analog (m) - Elevation of the highest point at which the facies/landform occurs along the modern shoreline.

Lower limit of modern analog (m) - Elevation of the lowest point at which the facies/landform occurs along the modern shoreline.

Quantification of Indicative meaning - Indicate how the indicative meaning has been quantified. Two selections are possible:
-IMCalc - Using the tool developed by Lorscheid and Rovere (2019)².
-Modern analog data - From modern analog data available for the study area. See example in Rovere et al., 2016¹.

Sea level datum - VErtical datum to which the elevations are referred. New sea level datums can be added from the Sea Level Datum table.

Elevation measurement technique - Method employed to measure elevations. New techniques can be added from the Elevation Measurement table.

Do you want to insert upper and lower elevation limits? - Select "Yes" if the sea level indicator was measured as two-points elevation (Figure 2).

Lower elevation of indicator - The lower measured elevation of the sea level indicator, as shown in Figure 2

Upper elevation of indicator - The upper measured elevation of the sea level indicator, as shown in Figure 2

Upper/Lower elevation measurement error (m) - Insert here the elevation measurement error for the Upper and Lower elevation measurements. Insert ±1-sigma values.

RSL indicator elevation (m) - Elevation of RSL indicator. This value is auto-calculated if upper and lower elevation limits are specified above.

RSL indicator elevation error (m) - Elevation error associated with the elevation measurement. For GPS and similar instrumental measurement, use ±1σ error levels. This value is auto-calculated if upper and lower elevation limits are specified above.

Notes on elevation - Insert comments on how elevation data has been obtained / treated.

Reference Water Level (m) - This value is auto-calculated from the previous ones, only if 'Sea level indicator' has been chosen in the 'Is this a marine/terrestrial limiting record?' field.

Indicative Range (m) - This value is auto-calculated from the previous ones, only if 'Sea level indicator' has been chosen in the 'Is this a marine/terrestrial limiting record?' field.

Paleo Relative Sea Level (m) - This value is auto-calculated from the previous ones, only if 'Sea level indicator' has been chosen in the 'Is this a marine/terrestrial limiting record?' field.

Paleo Relative Sea Level Uncertainty (m) - This value is auto-calculated from the previous ones, only if 'Sea level indicator' has been chosen in the 'Is this a marine/terrestrial limiting record?' field.

Is data on vertical land movements (independent from the sea level record) available? - Select 'Yes' or 'No' depending on the available data. If 'Yes' is selected, a new tab will open to insert vertical land movements accordingly.

Vertical Land Movements

This tab is displayed only if 'Yes' is selected in the field above.

Tectonic category - Select the tectonic category from a dropdown menu.

Comments on tectonic category - Comments on the tectonic category selection.

Published VLM rate (m/ky) - Vertical land motion rate as reported in the original study.

Published VLM rate uncertainty (m/ky)- Vertical land motion rate uncertainty as reported in the original study.

Interpreted VLM rate (m/ky) - Vertical land motion rate, if re-calculated from the original study.

Interpreted VLM rate (m/ky) uncertainty - Vertical land motion rate uncertainties, if re-calculated from the original study.

Comments on VLM rates - Insert here any further comment on vertical land motion rates.

Age Constraints

At least one age constraint must be entered in this tab. Without age constraints, a RSL datapoint cannot be saved.

Age attribution - Select one age attribution method from the list. The space below will populate accordingly.

U-series ages - Select one or more U-series ages. New ages can be added in the 'U-Series' table.

Amino Acid Racemization - Select one or more AAR ages. New ages can be added in the 'AAR' table.

Luminescence - Select one or more Luminescence ages. New ages can be added in the 'Luminescence' table.

Electro Spin Resonance - Select one or more ESR ages. New ages can be added in the 'ESR' table.

Stratigraphic context/age - Select one or more stratigraphic context ages. New ages can be added in the 'Chronostratigraphy' table.

Other age constraints - Select one or more other age constraints. New ages can be added in the 'Other age constraints' table.

Quality

This tab requires a creator-oriented an evaluation of the quality of the RSL data and age information.

Quality of RSL data - Rate the quality of the record for which concents RSL data, on a 1 (poor) to 5 (excellent) scale. If the record is rejected, select 0 stars and insert the reason for rejection below. A guide on the evaluation of quality can be found in Table 1

Quality of age information - Rate the quality of the record for which concerns age information, on a 1 (poor) to 5 (excellent) scale. If the record is rejected, select 0 stars and insert the reason for rejection below. A guide on the evaluation of quality can be found in Table 2

Quality notes - Detail the reason for the quality score assigned to the record or the reason for rejection.

Table 1. Guidelines for the evaluation of RSL data quality.

Description	Quality rating
Elevation precisely measured, referred to a clear datum and RSL indicator with a very narrow indicative range. Final RSL uncertainty is submetric.	5 (excellent)
Elevation precisely measured, referred to a clear datum and RSL indicator with a narrow indicative range. Final RSL uncertainty is between one and two meters.	4 (good)
Uncertainties in elevation, datum or indicative range sum up to a value between two and three meters.	3 (average)
Final paleo RSL uncertainty is higher than three meters	2 (poor)
Elevation and / or indicative range must be regarded as very uncertain due to poor measurement / description / RSL indicator quality	1 (very poor)
There is not enough information to accept the record as a valid RSL indicator (e.g. marine or terrestial limiting)	0 (rejected)

Table 2. Guidelines for the evaluation of age information quality.

Description	Quality rating
Very narrow age range, e.g. few ka, that allow the attribution to a specific timing within a substage of MIS 5 (e.g. 117±2 ka)	5 (excellent)
Narrow age range, allowing the attribution to a specific substage of MIS 5 (e.g., MIS 5e)	4 (good)
The RSL data point can be attributed only to a generic interglacial (e.g. MIS 5)	3 (average)
Only partial information or minimum age constraints are available	2 (poor)
Different age constraints point to different interglacials	1 (very poor)
Not enough information to attribute the RSL data point to any pleistocene interglacial.	0 (rejected)
