"Based on Tsounis and Edmunds (In press), Ecosphere:\\u00a0
Physical environmental conditions were characterized using three features that
are well-known to affect coral reef community dynamics (described in Glynn
1993, Rogers 1993, Fabricius et al. 2005): seawater temperature, rainfall, and
hurricane intensity. Together, these were used to generate seven dependent
variables describing physical environmental features. Seawater temperature was
recorded at each site every 15-30 min using a variety of logging sensors (see
Edmunds 2006 for detailed information on the temperature measurement regime).
Seawater temperature was characterized using five dependent variables
calculated for each calendar year: mean temperature, maximum temperature, and
minimum temperature (all averaged by day and month for each year), as well as
the number of days hotter than 29.3 deg C (\\u201chot days\\u201d), and the
number of days with temperatures greater than or equal to 26.0 deg C
(\\u201ccold days\\u201d). The temperature defining \\\"hot days\\\" was determined
by the coral bleaching threshold for St. John
([http://www.coral.noaa.gov/research/climate-change/coral-
bleaching.html](\\\\\"http://www.coral.noaa.gov/research/climate-change/coral-
bleaching.html\\\\\")), and the temperature defining \\\"cold days\\\" was taken as
26.0 deg C which marks the lower 12th percentile of all daily temperatures
between 1989 and 2005 (Edmunds, 2006). The upper temperature limit was defined
by the local bleaching threshold, and the lower limit defined the
12th\\u00a0percentile of local seawater temperature records (see Edmunds 2006
for details). Rainfall was measured at various locations around St. John (see
[http://www.sercc.com](\\\\\"http://www.sercc.com\\\\\")) but often on the north
shore (courtesy of R.\\u00a0Boulon) (see Edmunds and Gray 2014). To assess the
influence of hurricanes, a categorical index of local hurricane impact was
employed, with the index based on qualitative estimates of wave impacts in
Great Lameshur Bay as a function of wind speed, wind direction, and distance
of the nearest approach of each hurricane to the study area (see Gross and
Edmunds 2015). Index values of 0 were assigned to years with no hurricanes,
0.5 to hurricanes with low impacts, and 1 for hurricanes with high impacts,
and years were characterized by the sum of their hurricane index values.";

"Long Term Research in Environmental Biology (LTREB) in US Virgin Islands:
From the NSF award abstract:
In an era of growing human pressures on natural resources, there is a critical need to understand how major ecosystems will respond, the extent to which resource management can lessen the implications of these responses, and the likely state of these ecosystems in the future. Time-series analyses of community structure provide a vital tool in meeting these needs and promise a profound understanding of community change. This study focuses on coral reef ecosystems; an existing time-series analysis of the coral community structure on the reefs of St. John, US Virgin Islands, will be expanded to 27 years of continuous data in annual increments. Expansion of the core time-series data will be used to address five questions: (1) To what extent is the ecology at a small spatial scale (1-2 km) representative of regional scale events (10's of km)? (2) What are the effects of declining coral cover in modifying the genetic population structure of the coral host and its algal symbionts? (3) What are the roles of pre- versus post-settlement events in determining the population dynamics of small corals? (4) What role do physical forcing agents (other than temperature) play in driving the population dynamics of juvenile corals? and (5) How are populations of other, non-coral invertebrates responding to decadal-scale declines in coral cover? Ecological methods identical to those used over the last two decades will be supplemented by molecular genetic tools to understand the extent to which declining coral cover is affecting the genetic diversity of the corals remaining. An information management program will be implemented to create broad access by the scientific community to the entire data set.
The importance of this study lies in the extreme longevity of the data describing coral reefs in a unique ecological context, and the immense potential that these data possess for understanding both the patterns of comprehensive community change (i.e., involving corals, other invertebrates, and genetic diversity), and the processes driving them. Importantly, as this project is closely integrated with resource management within the VI National Park, as well as larger efforts to study coral reefs in the US through the NSF Moorea Coral Reef LTER, it has a strong potential to have scientific and management implications that extend further than the location of the study.

"The recent past has not been good for coral reefs, and journals have been filled with examples of declining coral cover, crashing fish populations, rising cover of macroalgae, and a future potentially filled with slime. However, reefs are more than the corals and fishes for which they are known best, and their biodiversity is affected strongly by other groups of organisms. The non-coral fauna of reefs is being neglected in the rush to evaluate the loss of corals and fishes, and this project will add on to an on-going long term ecological study by studying soft corals. This project will be focused on the ecology of soft corals on reefs in St. John, USVI to understand the Past, Present and the Future community structure of soft corals in a changing world. For the Past, the principal investigators will complete a retrospective analysis of octocoral abundance in St. John between 1992 and the present, as well as Caribbean-wide since the 1960's. For the Present, they will: (i) evaluate spatio-temporal changes between soft corals and corals, (ii) test for the role of competition with macroalgae and between soft corals and corals as processes driving the rising abundance of soft corals, and (iii) explore the role of soft corals as \"animal forests\" in modifying physical conditions beneath their canopy, thereby modulating recruitment dynamics. For the Future the project will conduct demographic analyses on key soft corals to evaluate annual variation in population processes and project populations into a future impacted by global climate change.
This project was funded to provide and independent \"overlay\" to the ongoing LTREB award (DEB-1350146, co-funded by OCE, PI Edmunds) focused on the long-term dynamics of coral reefs in St. John.

Data Access Protocol (DAP) and its

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").
