Methods & Sampling

To assess local and regional variation in shell thickness plasticity, we conducted a field experiment that utilized 12 Littorina obtusata populations in the Gulf of Main (GOM), with 6 in the northern Gulf and 6 in the southern Gulf (see Related Datasets). Seawater temperature was recorded at high tide at study sites prior to and during the outplant experiment. All temperature data were recorded by Tidbit temperature loggers (Onset Computer Corporation) placed in the intertidal zone at +1.5 meters Mean Low Water. Temperature was sampled at 5-minute intervals and temperature values corresponding to daily high tides were extracted for statistical analyses.

Data Processing Description

Data were first recorded manually on paper and then transferred to digital spreadsheets. Fidelity between paper and digital versions of the data were proofed by both Corbett and Trussell.

BCO-DMO Processing

- Imported original file named Data from Local and Regional Geographic Variation in Inducible Defenses.Temperature.Pre.Expt.xlsx" into the BCO-DMO system.
- Renamed fields/columns to comply with BCO-DMO naming conventions.
- Removed degrees symbols from LATITUDE and LONGITUDE columns.
- Made LONGITUDE values negative because they're in the Western hemisphere.
- Converted DATE column to YYYY-MM-DD format.
- Saved the final file as "911409_v1_temps_outplant_expt.csv".
