RNA-seq data from Ecklonia radiata exposed to single and repeated marine heatwaves

This dataset contains raw RNA sequencing reads from juvenile Ecklonia radiata (Laminariales) collected from Bruny Island, Tasmania, and used in a controlled laboratory heatwave experiment. Individuals were exposed to ambient, single, or repeated marine heatwave treatments to assess the effects of thermal stress and recovery. Total RNA was extracted from blade tissue and sequenced on an Illumina platform to generate paired-end reads. The data represent high-quality raw FASTQ files (n = 30 samples; 5 replicates per treatment per time point) suitable for transcriptomic analyses examining the molecular responses of E. radiata to marine heatwaves.
