String acquisition_description
"Prior to the 2017 hurricanes, six shallow (8-15 m depth) reef sites had been
selected from the Virgin Islands Territorial Coral Reef Monitoring
Program\\u2019s (TCRMP) permanent monitoring sites to study variation in sponge
communities in St. Thomas. These sites included Black Point
(N18\\u00b0\\u00a020.665\\u2019, W64\\u00b0\\u00a059.107\\u2019), Coculus Rock
(N18\\u00b0\\u00a018.734\\u2019, W64\\u00b0\\u00a051.613\\u2019), and Magens Bay
(N18\\u00b0 22.459\\u2019, W64\\u00b0 56.077\\u2019), which are in embayments with
heavily developed watersheds. Buck Island (N18\\u00b0 16.717\\u2019, W64\\u00b0
53.925\\u2019) and Savana Island (N18\\u00b0\\u00a020.437\\u2019,
W65\\u00b0\\u00a004.939\\u2019) are located near undeveloped offshore cays.
Botany Bay (N18\\u00b0\\u00a021.433\\u2019, W65\\u00b0\\u00a002.071\\u2019) is a
nearshore site in a bay with a low level of watershed development. For this
study, we used three randomly selected transects out of the six permanently
established 10 m TCRMP transects at each site. The same three transects at
each site were re-surveyed repeatedly in August 2015, August 2016 (pre-
hurricanes) and December 2017 (10 weeks post-hurricanes).\\u00a0
At each site, sponge volume was calculated within permanent 1 m2\\u00a0quadrats
centered on the transect line within the initial and/or final meter of the
transect. Sponge volume was calculated for 3-5 quadrats per site. As there
were over 80 species of sponges within our survey areas, representing a wide
diversity of morphologies, we chose to use a standardized measurement approach
for all sponges, rather than calculating the true volumetric measurement for
each sponge based on its actual morphology. Thus, sponges were essentially
treated as cuboids. We used a flexible sewing tape to measure the longest
dimension of the sponge, then one to several width measurements perpendicular
to the initial length measurement, and one to several height measurements, as
needed to represent the shape and dimensions of each sponge. Multiple
measurements for each dimension were averaged and length x width x height was
calculated. For large tubes, of which there were relatively few, we subtracted
the dimensions of the interior cavity from the exterior dimensions of the
sponge. Generated data were in cm3 of sponge/m2 (Gochfeld et al. 2020).";

"NSF Award Abstract:
Over the past several decades, coral reefs worldwide have undergone a transition from being dominated by the corals themselves to being dominated by sponges or algae. The causes of these changes are complex, but they include both natural stressors, such as diseases and hurricanes, and impacts from human activities, such as coastal development and climate change. There are over 600 species of sponges on Caribbean coral reefs, and they serve many important ecological roles, including nutrient cycling, providing food and shelter for other reef animals, and producing a tremendous diversity of chemical compounds that are important for controlling species interactions on the reef, and may serve as potential new drugs. In spite of their importance on coral reefs, there are many aspects of sponge biology that remain unknown, including how they respond to different types of stressors. Coral reefs in St. Thomas, in the U.S. Virgin Islands, are exposed to different levels of man-made stressors, depending upon their proximity to coastal development, and the sponge assemblages on these reefs also vary with levels of human impacts. In September 2017, St. Thomas was devastated by two Category 5 hurricanes in a row. Since, unlike corals, virtually nothing is known about what happens to sponge communities in the aftermath of hurricanes, the research team will use a combination of field ecology and population genetics approaches to determine how sponge communities respond and recover from these devastating storms and whether prior exposure to land-based stressors affects their recovery. Researchers at the Universities of Mississippi, Alabama and the Virgin Islands will participate in this RAPID project, and will provide training opportunities for students and postdoctoral researchers, especially from underrepresented groups. Information will be provided to resource managers in the Virgin Islands, along with outreach programs to community groups in St. Thomas.
The goal of this project is to assess the impacts of single (e.g., hurricanes) versus multiple (e.g., hurricanes and land-based sources of pollution) stressors on the resilience, recovery, and recruitment of sponge communities in St. Thomas, U.S.V.I. Given the growing dominance of sponges on coral reefs worldwide, understanding the responses of sponges to natural and anthropogenic stressors is increasingly important. The investigators will leverage multiple years of data on sponge assemblages from several sites around the island of St. Thomas that varied in their levels of exposure to local land-based stressors prior to Hurricanes Irma and Maria, and evaluate changes to these diverse assemblages over time, beginning within 3 months of these devastating storms. Using a combination of natural and experimentally cleared plots, the investigators will assess the progress of sponge succession and whether the presence of algae interferes with sponge recruitment and recovery. Subsamples of recruits and nearby conspecifics will be collected to evaluate population genetic diversity and potential sources of new individuals. The data resulting from this project will provide critical insights into sponge resilience in response to hurricanes at sites previously exposed to land-based stressors, the initiation of succession within sponge communities, potential predictors of successional trajectory, and genetic diversity within sponge populations following a storm event. This information will help identify factors that inhibit coral recovery and potential approaches to enhance resilience of coral reefs.";

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
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
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").
