This part of the data release presents projected flooding extent polygon (flood masks) shapefiles based on wave-driven total water levels for Commonwealth of Puerto Rico. There are eight associated flood mask and flood depth shapefiles: one for each of four nearshore wave energy return periods (rp; 10-, 50-, 100-, and 500-years), the pre-storm scenario (base) and the post-storm scenarios.
A secchi disk is used to estimate the water transparency depth of surface-water bodies. Secchi disk depth was measured monthly at Caño Boquerón, Cabo Rojo, and Puerto Mosquito, Isla de Vieques; Puerto Rico for the period from July 2015 to July 2016. This data release is part of a limnological analysis at Caño Boquerón and Puerto Mosquito to assess the principal factors affecting the hydrology and water-quality conditions. In addition, the study provides baseline information to regulatory agencies responsible for the management and conservation of coastal waters in Puerto Rico. The investigation focused on Caño Boquerón, and Puerto Mosquito surface-water bodies, representing disturbed and undisturbed conditions,...
The U.S. Geological Survey (USGS) maintains shoreline positions for the United States coasts from both older sources, such as aerial photographs or topographic surveys, and contemporary sources, such as lidar-point clouds and digital elevation models. These shorelines are compiled and analyzed in the Digital Shoreline Analysis System software to compute their rates of change. Keeping a record of historical shoreline positions is an effective method to monitor change over time, enabling scientists to identify areas most susceptible to erosion or accretion. These data can help coastal managers understand which areas of the coast are vulnerable to change. This data release, and other associated products, represent...

This dataset consists of a shapefile of points corresponding to water depth collected for the bathymetric survey of Puerto Mosquito, in Isla de Vieques, Puerto Rico, on August 11, 2015. The U.S. Geological Survey, in cooperation with the Puerto Rico Environmental Quality Board, conducted a limnological study at Puerto Mosquito in Vieques to assess the principal mechanisms affecting the hydrology and water quality characteristics. The study characterized hydrologic and physical-chemical properties, sediment deposition rates, bathymetry, and biological conditions. The bathymetric survey system used for the study consisted of coupling a global positioning system (GPS) device with a water depth sounder. Established...

This data release provides flooding extent polygons (flood masks) and depth values (flood points) based on wave-driven total water levels for 22 locations within the States of Hawaii and Florida, the Territories of Guam, American Samoa, Puerto Rico, and the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands. For each of the 22 locations there are eight associated flood mask polygons and flood depth point files: one for each four nearshore wave energy return periods (rp; 10-, 50-, 100-, and 500-years) and both with (wrf) and without (worf) the presence of coral reefs. These flood masks can be combined with economic, ecological, and engineering tools to provide a rigorous financial valuation...
This part of the data release presents projected flooding extent polygon (flood masks) and flooding depth points (flood points) shapefiles based on wave-driven total water levels for the Territory of Puerto Rico (the islands of Culebra, Puerto Rico, and Vieques). For each island there are 8 associated flood mask and flood depth shapefiles: one for each four nearshore wave energy return periods (rp; 10-, 50-, 100-, and 500-years) and both with (wrf) and without (worf) the presence of coral reefs. Flooding depth point data are also presented as a comma-separated value (.csv) text file.

This dataset contains measurements of dissolved oxygen concentrations collected at Caño Boquerón in Cabo Rojo, and Puerto Mosquito, Isla de Vieques, Puerto Rico. The method consists of in-situ incubation of two light-and-dark bottles for approximately four hours. Dissolved oxygen concentrations were determined using the Winkler method. A total of twelve monthly in-situ incubations were conducted from July 2015 to July 2016. For each bottle incubated, two or three titrations were conducted and an average of the DO calculations is presented.

This part of the data release presents projected flooding extent polygon (flood masks) shapefiles based on wave-driven total water levels for the Commonwealth of Puerto Rico. There are 16 associated flood mask and flood depth shapefiles: one for each of four nearshore wave energy return periods (rp; 10-, 50-, 100-, and 500-years), the current scenario (base) and each of the restoration scenarios (structural_25, structural_05, and ecological_25).
This data release provides flooding extent polygons based on wave-driven total water levels for the coral lined coast of Florida and the Commonwealth of Puerto Rico. The wave and sea-level conditions were then propagated using the XBeach over 100-m spaced shore-normal transects modified to account for base and post-storm scenarios. In situ observations following hurricanes Irma and Maria were used to create classifications of impact level to reefs where 0 = no impact, 0 - 0.05 = minor impact, 0.05 - 0.15 = moderate impact, and 0.15 - 1.00 = major impact. Categories were converted into numeric values of 0, 1, 2, and 3 that corresponded with the none, minor, moderate, and major damage category, respectively. These...

The dataset contains the selected physical properties and chemical constituents that were measured at Caño Boquerón, Cabo Rojo, and Puerto Mosquito, Isla de Vieques, Puerto Rico during a diurnal cycle. Two diel studies were conducted per lagoon to determine the community primary productivity. Photosynthesis creates oxygen which enhances microbiological activity and results in the production of organic matter. Primary productivity is important for supporting the food web in aquatic ecosystems. The field data collection included the measurement of temperature, dissolved oxygen, and percent of oxygen saturation. Measurements were obtained at about 1 hour intervals. Diel studies were conducted on October 29, 2015 and...
