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.

This dataset contains raw RNA sequencing reads from juvenile Ecklonia radiata (Laminariales) collected from Coal Point, Tasmania, and used in a controlled laboratory experiment examining the effects of temperature and elevated CO₂ on gene expression. Individuals were exposed to three temperatures (6, 16, and 26 °C) under two CO₂ levels: current (~420 µatm) and future (~1000 µatm), representing RCP 8.5 projections. Total RNA was extracted from blade tissue and sequenced on an Illumina NovaSeq 6000 platform to produce 150 bp paired-end reads. The dataset includes raw FASTQ files from 30 biological samples (n = 5 per treatment combination) used for transcriptomic analyses investigating the molecular responses of E. radiata to ocean warming and acidification.
