Lake Joyce Bathymetry and Isotope Data for Glacial Refugium Analysis

A 2026 dataset by Tyler Mackey presents a bathymetric model, water isotope values (δ¹⁸O and δ²H), and chloride budget for Lake Joyce in Antarctica's McMurdo Dry Valleys. The data reassesses the lake's history and its potential role as a proglacial refugium for the endemic copepod Diacyclops joycei. It includes files in MOV, DOCX, and JPG formats totaling 44.7 MB.

Use Cases

• Modeling glacial lake evolution based on bathymetric and isotopic data.
• Assessing freshwater refugia for endemic species based on chloride budgets and lake history.
• Reconstructing regional hydrological changes from water isotope (δ¹⁸O and δ²H) values.

Strengths

• Includes a new lake bathymetric model for a specific Antarctic site.
• Contains water isotope (δ¹⁸O and δ²H) values and a chloride budget for hydrological analysis.
• Released under a CC-BY-4.0 license for open use.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is 44.7 MB, which is relatively small in scale.
