Biogeochemistry Data from Jones Sound and Nares Strait, 2021.

This August 2021 dataset provides an assessment of phytoplankton communities, Rubisco protein abundance, and associated environmental conditions from Arctic marine ecosystems, with a focus Jones Sound and Nares Strait. This metadata accompanies the publication By White et al. 2025, "Shifting phytoplankton ecological strategies along a continuum of tidewater glacier retreat". The dataset includes multiple components:

1. Phytoplankton Rubisco Protein Data
• Dataset: Rubisco_data_meta_CAA_PPCC_06052024.csv
• Description: Quantitative measurements of Rubisco peptides derived from mass spectrometry-based proteomics, including peptide-specific abundances across multiple Arctic stations. Metadata includes associated environmental parameters such as macronutrient concentrations (nitrate, phosphate, silicate) and trace metals (iron, cadmium, manganese).

2. Chlorophyll-a and Environmental Tracer Data
• Dataset: chla_tracer_data_rubisco_CAA_PPCC.csv
• Description: Profiles of chlorophyll-a fluorescence, oxygen concentration, temperature, salinity, and turbidity for pairing with Rubisco data.

3. Phytoplankton 16S Community Composition (ASVs)
• Dataset: formated_ASVs_chl_CAA_PPCC_04242024.csv
• Description: Amplicon sequencing data resolving the taxonomic identity of phytoplankton and microbial communities, including assigned ASVs (amplicon sequence variants) and associated metadata.

4. Phytoplankton Taxonomy
• Dataset: formated_phytoref_chl_CAA_PPCC_04242024.csv
• Description: Taxonomy associated with ASVs as assigned via PhytoREF.

5. Environmental Metadata from Arctic Stations
• Dataset: devon_metadata_microbial_2021_5m_meaned_complete_06_05_2024.2.csv
• Description: Hydrographic, chemical, and ecological metadata from multiple sampling sites, including glacier proximity, depth, nutrients, and CTD data.
