Antarctic Moss Photosynthesis Data from Casey Station and King George Island

Field and laboratory measurements of moss surface temperatures, photosynthetic yield, and electron transport rate were collected at Casey Station, East Antarctica over four field seasons (2003, 2011, 2012, 2013) and at King George Island, Maritime Antarctica in 2015 and 2019. Alicia Perera-Castro and co-authors produced this dataset to support a manuscript published in Frontiers of Plant Science in July 2020. The Excel file contains individual sheets corresponding to figures in the published paper.

Use Cases

• Model photosynthetic temperature optima for Antarctic moss species based on yield and electron transport rate measurements.
• Compare field surface temperature patterns between moss microtopography ridges and valleys.
• Analyze the relationship between photosynthetic photon flux density (PPFD) and physiological parameters in laboratory conditions.

Strengths

• Data spans multiple field seasons from 2003 to 2019, providing temporal depth.
• Includes both field measurements (surface temperatures) and controlled laboratory experiments (photosynthetic parameters).
• Data is structured to directly support a peer-reviewed publication, indicating methodological rigor.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data from the 2019 field season is under embargo and not included in the public file.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
