Global sea level and Earth's climate are closely linked. Using speleothem encrustations from coastal caves on the island of Mallorca, we determined that western Mediterranean relative sea level was approximately 1 meter above modern sea level approximately 81,000 years ago during marine isotope stage (MIS) 5a. Although our findings seemingly conflict with the eustatic sea-level curve of far-field sites, they corroborate an alternative view that MIS 5a was at least as ice-free as the present, and they challenge the prevailing view of MIS 5 sea-level history and certain facets of ice-age theory.

Radon loss from water during storage in polyethylene terephthalate (PET) and polylactic acid (PLA) bottles was evaluated. Surface/volume ratio and thickness of plastic materials were studied. A correction for dissolved radium concentration was applied to estimate gas loss. Proper corrections for degassing efficiency of aerators were developed. The interference of H2O on radon daughter electrostatic collection was quantified.
