Specific growth rate measurements for 46 Southern Ocean diatoms

This dataset includes records of the specific growth rates measured for 46 clonal diatom strains originally isolated during the research cruise NBP-1701 across the Pacific sector of the Southern Ocean during December 2016-January 2017. Strains were grown under continuous light (130 µmol m-2 s-1) at up to 8 temperatures that span all or most of each strain’s thermal niche width, from 0-12 degrees C, which encompasses each strain’s optimum temperature for growth. Strains have been molecularly identified to species via 18S Sanger sequencing. Data include the following information for each record: Internal lab strain reference ID, date collected, latitude, longitude, Southern Ocean region, species, tested temperature, replicate number and specific growth rate. Data are provided in comma-separated values (csv) format.
