This project focused on developing molecular tools based on relative gene expression to investigate physiological ecology of Calanus finmarchicus (Calanoida: Copepoda) in the Gulf of Maine. For this project, a custom microarray was developed for this species and tested on field and experimental data. Using RNA-seq technology, a de novo transcriptome was obtained from RNA extracted from different developmental stages of C. finmarchicus from embryo to adult female.

Datasets generated through this project were deposited at NCBI (www.ncbi.nlm.nih.gov) in 5 separate NCBI BioProjects:

BioProject PRJNA151477 (www.ncbi.nlm.nih.gov/bioproject/PRJNA151477): Microarray platform information and relative expression data for lipid-rich vs. lipid-poor pre-adults (stage CV) and adult females maintained at high- and low-food levels.
BioProject PRJNA149523 (www.ncbi.nlm.nih.gov/bioproject/PRJNA1495230): Microarray platform information and relative expression data for pre-adults (stage CV) and adult females collected from depth (130-170 m) and from surface waters (0-30 m).
BioProject PRJNA236528 (www.ncbi.nlm.nih.gov/bioproject/PRJNA236528): RNA-Seq data. Data includes biosample description, raw sequence data for each sample, and transcriptome shotgun assembly of sequences. Calanus finmarchicus transcriptome from 6 developmental stages (embryo, early nauplius, late nauplius, early copepodite, late copepodite and adult females).
