"Seven colonies of A. hyacinthus from the back-reef environment of Ofu Island
were tagged, sampled, and monitored at five time-points spanning the bleaching
event: before bleaching representing baseline expression levels (August 2011),
and then two months (April 2015), six months (August 2015), 10 months
(December 2015) and 12 months (February 2016) after initial bleaching was
observed in February 2015. Coral nubbins of approximately 24 cm in size were
collected from colonies within 3 h of high-tide using garden clippers and
preserved in RNAlater. All colonies occurred at depths of approximately 0.51.0
m and were within a 2500 m2area of back-reef. Total RNA was extracted from
tissue samples using Qiagen's RNAeasy Plus Kit, and 35 cDNA libraries (seven
colonies for five dates) were generated using the Illumina TruSeq RNA Library
Prep Kit v2 with Protoscript II Reverse Transcriptase. The 35 libraries were
multiplexed and sequenced across three lanes on a Hiseq2500 at the University
of Utah Microarray and Genomic Analysis Core Facility.
Location: Ofu Island, American Samoa. All data and samples were collected from
the lagoon environment in the National Park of American Samoa at depths less
than 3.0m.";

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.";

"Description from NSF award abstract:
The strongest coral bleaching event in nearly 20 years began in American Samoa in January 2015. Coral bleaching occurs when ocean water temperatures exceed a coral's normal heat tolerance. But bleaching events usually show an unexplained pattern - colonies next to one another can show very different levels of bleaching - from pure white to the normal tan color of a healthy coral. The investigators have observed this pattern among 280 corals on reefs in American Samoa that have been studied for years. This system will be used to test four major hypotheses about what causes some corals to bleach and some not: differences in 1) species, 2) the temperature the corals experienced, 3) the symbiont they harbor, and 4) the genotype of the coral host. In addition, the investigators will return to American Samoa at regular intervals to measure the rate of recovery of each coral colony and conduct the same tests as above for recovery rate. The stark-white reefscapes left behind by bleaching events are one of the most common signals of increased ocean warming. This work will take advantage of years of prior study and the advent of a coral bleaching event to understand the rules for survival on reefs.
The reefs of American Samoa began showing a major bleaching event starting in January 2015, including 62 corals that have been intensively studied for coral thermal resistance, field temperatures, and symbiont type. In April 2015 the investigators monitored bleaching status of these and additional corals, totaling 280 corals from four species, and uncovered marked variation in bleaching extent within and between species and within and between reef regions. The team will test the relative importance of microclimate to bleaching state by examining records of approximately 50 temperature loggers in place since before the bleaching event. They will test the influence of symbiont type and host gene expression profiles by examining samples of 60 colonies taken at four time points after bleaching. The investigators will also examine the full suite of 280 corals for genetic variation to estimate the relationship between bleaching state, recovery rate and genetic polymorphism. These data will be used to test micro-climate, symbiont, and coral genetics as determinants of bleaching and bleaching recovery. Because the investigators have samples from these 280 colonies before bleaching mortality, this study will provide the first estimate for the evolutionary impact of a bleaching event on coral populations.";

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.
