Giant Kelp Thermal Tolerance Ecophysiology Data from Tasmania

Ecophysiological measurements from thermal tolerance testing of specific warm-tolerant and normal family-lines of giant kelp (Macrocystis pyrifera) from Tasmania, Australia. The data includes growth, nutrient usage, fatty acid content, and photosynthetic measurements from cultivation trials at cool (16 °C) and warm (20 °C) temperatures. The work was conducted under the NESP MaC 1.28 project and published via the Australian Ocean Data Network.

Use Cases

• Compare growth performance between warm-tolerant and normal kelp strains based on cultivation trial data.
• Analyze physiological mechanisms of thermal tolerance based on nutrient usage (carbon and nitrogen content) data.
• Investigate cellular membrane adaptation based on fatty acid composition measurements.
• Assess photosynthetic efficiency under thermal stress based on PAM fluorometry and pigment data.
• Inform kelp breeding and selection programs for climate-resilient restoration based on the identified physiological traits.

Strengths

• Data includes controlled cultivation trials at two specific temperatures (16 °C and 20 °C).
• Physiological assessments cover multiple mechanisms: nutrient usage, fatty acids, and photosynthesis.
• Focuses on specific, previously identified warm-tolerant and normal kelp strains from Tasmania.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Tasmanian source location.
