Dataset: Phytoplankton MicroTOOLs microarray-based metatranscriptomes collected from a nutrient amendment experiment conducted during R/V New Horizon Cruise NH1417 in the California Current System from 2014-08-23 to 2014-08-26

Transcription changes by surface microbial communities from the California Current System in response to added nitrogen and/or iron substrates were assessed using MicroTOOLs microarrays. Samples were collected during the R/V New Horizon Cruise NH1417 in 2014.

These data are available at The National Center for Biotechnology Information (NCBI) under NCBI Gene Expression Omnibus (GEO) accession number GSE130464 https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE130464. BioProject https://www.ncbi.nlm.nih.gov/bioproject/PRJNA540297.

The manuscript "Phytoplankton transcriptomic and physiological responses to fixed nitrogen in the California Current System" by Shilova and Magasin et al. (2020) describes the experiment, metatranscriptomic data, and results. The previously published manuscript details other measurements obtained from the same experiment and includes phytoplankton cell counts, Fast Repetition Rate Fluorometry measurements, nutrients and Chlorophyll a concentrations, and 16S rRNA gene sequences (Shilova et al., 2017).
