    String acquisition_description 
"Seawater was collected from the San Pedro Ocean Time-series (SPOT) station off
the coast of Southern California near the surface (5 m), 150 and 890 m, in
late May 2015. Briefly, seawater was pre-filtered (80 mm) into 20 L carboys to
minimize the presence of multicellular eukaryotes. Replicate samples (ranging
in volume from 1.5-3.5 L) from each depth were filtered onto sterile GF/F
filters (nominal pore size 0.7 mm, Whatman, International Ltd. Florham Park,
NJ). While we cannot avoid some impact that sample handling (i.e., bringing
samples to the surface) may have had on our results, filters were immediately
placed in 1.5 mL of lysis buffer and flash frozen in liquid nitrogen in < 40
min and away from light to minimize RNA degradation.
Total RNA was extracted from each filter using a DNA/RNA AllPrep kit (Qiagen,
Valencia, CA, #80204) with an in-line genomic DNA removal step (RNase-free
DNase reagents, Qiagen #79254) (dx.doi.org/10.17504/protocols.io.hk3b4yn).
Extracted RNA was quality checked and low biomass samples were pooled. Six
replicates were processed and sequenced from the surface, while pairs of
filters were pooled for either 150 or 890 m, yielding 3 and 4 replicates
respectively (Supporting Information Table S1). RNA concentrations were
normalized before library preparation (Supporting Information). ERCC spike-in
was added before sequence library preparation with Kapa\\u2019s Stranded mRNA
library preparation kit using poly-A tail selection beads to select for
eukaryotic mRNA (Kapa Biosystems, Inc., Wilmington, MA, #KK8420).

"Planktonic marine microbial communities consist of a diverse collection of bacteria, archaea, viruses, protists (phytoplankton and protozoa) and small animals (metazoan). Collectively, these species are responsible for virtually all marine pelagic primary production where they form the basis of food webs and carry out a large fraction of respiratory processes. Microbial interactions include the traditional role of predation, but recent research recognizes the importance of parasitism, symbiosis and viral infection. Characterizing the response of pelagic microbial communities and processes to environmental influences is fundamental to understanding and modeling carbon flow and energy utilization in the ocean, but very few studies have attempted to study all of these assemblages in the same study. This project is comprised of long-term (monthly) and short-term (daily) sampling at the San Pedro Ocean Time-series (SPOT) site. Analysis of the resulting datasets investigates co-occurrence patterns of microbial taxa (e.g. protist-virus and protist-prokaryote interactions, both positive and negative) indicating which species consistently co-occur and potentially interact, followed by examination gene expression to help define the underlying mechanisms. This study augments 20 years of baseline studies of microbial abundance, diversity, rates at the site, and will enable detection of low-frequency changes in composition and potential ecological interactions among microbes, and their responses to changing environmental forcing factors. These responses have important consequences for higher trophic levels and ocean-atmosphere feedbacks. The broader impacts of this project include training graduate and undergraduate students, providing local high school student with summer lab experiences, and PI presentations at local K-12 schools, museums, aquaria and informal learning centers in the region. Additionally, the PIs advise at the local, county and state level regarding coastal marine water quality.
This research project is unique in that it is a holistic study (including all microbes from viruses to small metazoa) of microbial species diversity and ecological activities, carried out at the SPOT site off the coast of southern California. In studying all microbes simultaneously, this work aims to identify important ecological interactions among microbial species, and identify the basis(es) for those interactions. This research involves (1) extensive analyses of prokaryote (archaean and bacterial) and eukaryote (protistan and micro-metazoan) diversity via the sequencing of marker genes, (2) studies of whole-community gene expression by eukaryotes and prokaryotes in order to identify key functional characteristics of microorganismal groups and the detection of active viral infections, and (3) metagenomic analysis of viruses and bacteria to aid interpretation of transcriptomic analyses using genome-encoded information. The project includes exploratory metatranscriptomic analysis of poorly-understood aphotic and hypoxic-zone protists, to examine their stratification, functions and hypothesized prokaryotic symbioses.";

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.

Tabledap request URLs must be in the form
For example,
Thus, the query is often a comma-separated list of desired variable names, followed by a collection of constraints (e.g., variable<value), each preceded by '&' (which is interpreted as "AND").

For details, see the tabledap Documentation.
