This data submission consists of metabarcoding data for the zooplankton community in the epipelagic, mesopelagic and upper bathypelagic zones (0-1500m) of the North Pacific Subtropical Gyre. The goal of this study was to assess the hidden diversity present in zooplankton assemblages in midwaters, and detect vertical gradients in species richness, depth distributions, and community composition of the full zooplankton assemblage. Samples were collected in June 2014 from Station ALOHA (22.75, -158) using a 1-meter square Multiple Opening and Closing Nets and Environmental Sampling System (MOCNESS, 200um mesh), on R/V Falkor cruise FK140613. Next generation sequence data (Illumina MiSeq, V3 chemistry, 300-bp paired-end) of the zooplankton assemblage derive from amplicons of the V1-V2 region of 18S rRNA (primers described in Fonseca et al. 2010). The data includes sequences and read count abundance information for molecular OTUs from both holoplanktonic and meroplanktonic taxa. All results derive from analyses in mothur v1.36.1 (Schloss et al. 2009, Kozich et al. 2013).
Tables from four analyses are included in this submission:
1) 97_OTUtable: read counts for each OTU (clustered at 97% similarity) across 54 samples (depth, size fractionated), with NCBI BLAST results for the top representative sequence from each OTU.
2) 97_OTU_subsampled: read counts for each OTU (clustered at 97% similarity), subsampled for even sequencing coverage across 54 samples (depth, size fractionated, with NCBI BLAST results for the top representative sequence from each OTU.
3) 99_OTU: read counts for each OTU (clustered at 99% similarity) across 54 samples (depth, size fractionated), with NCBI BLAST results for the top representative sequence from each OTU.
4) 99_OTU_subsampled: read counts for each OTU (clustered at 99% similarity), subsampled for even sequencing coverage across 54 samples (depth, size fractionated), with NCBI BLAST results for the top representative sequence from each OTU.

| Dataset-specific Instrument Name | Illumina MiSeq |
| Generic Instrument Name | Automated DNA Sequencer |
| Dataset-specific Description | Illumina MiSeq using V3 chemistry (300-bp, paired-end) |
| Generic Instrument Description | General term for a laboratory instrument used for deciphering the order of bases in a strand of DNA. Sanger sequencers detect fluorescence from different dyes that are used to identify the A, C, G, and T extension reactions. Contemporary or Pyrosequencer methods are based on detecting the activity of DNA polymerase (a DNA synthesizing enzyme) with another chemoluminescent enzyme. Essentially, the method allows sequencing of a single strand of DNA by synthesizing the complementary strand along it, one base pair at a time, and detecting which base was actually added at each step. |
| Dataset-specific Instrument Name | Agilent 2100 Bioanalyzer |
| Generic Instrument Name | Bioanalyzer |
| Generic Instrument Description | A Bioanalyzer is a laboratory instrument that provides the sizing and quantification of DNA, RNA, and proteins. One example is the Agilent Bioanalyzer 2100. |
| Dataset-specific Instrument Name | quantitative PCR by the Evolutionary Genetics Core Facility (Hawaii Institute of Marine Biology) |
| Generic Instrument Name | Thermal Cycler |
| Generic Instrument Description | A thermal cycler or "thermocycler" is a general term for a type of laboratory apparatus, commonly used for performing polymerase chain reaction (PCR), that is capable of repeatedly altering and maintaining specific temperatures for defined periods of time. The device has a thermal block with holes where tubes with the PCR reaction mixtures can be inserted. The cycler then raises and lowers the temperature of the block in discrete, pre-programmed steps. They can also be used to facilitate other temperature-sensitive reactions, including restriction enzyme digestion or rapid diagnostics.

| Description | Student Cruise #3
More about this cruise from the Schmidt Ocean Institute page:
https://schmidtocean.org/cruise/net-gains-at-station-aloha/ |
Description from NSF award abstract:
Marine zooplankton show strong ecological responses to climate change, but little is known about their capacity for evolutionary response. Many authors have assumed that the evolutionary potential of zooplankton is limited. However, recent studies provide circumstantial evidence for the idea that selection is a dominant evolutionary force acting on these species, and that genetic isolation can be achieved at regional spatial scales in pelagic habitats. This RAPID project will take advantage of a unique opportunity for basin-scale transect sampling through participation in the Atlantic Meridional Transect (AMT) cruise in 2014. The cruise will traverse more than 90 degrees of latitude in the Atlantic Ocean and include boreal-temperate, subtropical and tropical waters. Zooplankton samples will be collected along the transect, and mitochondrial and microsatellite markers will be used to identify the geographic location of strong genetic breaks within three copepod species. Bayesian and coalescent analytical techniques will test if these regions act as dispersal barriers. The physiological condition of animals collected in distinct ocean habitats will be assessed by measurements of egg production (at sea) as well as body size (condition index), dry weight, and carbon and nitrogen content. The PI will test the prediction that ocean regions that serve as dispersal barriers for marine holoplankton are areas of poor-quality habitat for the target species, and that this is a dominant mechanism driving population genetic structure in oceanic zooplankton.
Note: This project is funded by an NSF RAPID award. This RAPID grant supported the shiptime costs, and all the sampling reported in the AMT24 zooplankton ecology cruise report (PDF).
