This dataset is a point shapefile containing water-depth points collected during a sedimention survey of Lago Guayabal conducted during the period December 11- December 14, 2017 by the Puerto Rico office of the Caribbean-Florida Water Science Center of the U.S. Geological Survey (USGS). The goals of the survey were to determine reservoir infill sedimentation rates, generate a bathymetric map of the reservoir, and create a stage-volume relation. More than 270,000 water-depth points were surveyed along 60 navigation lines used in previous sedimentation surveys (Soler-Lopez, 2003, 2007, 2008). All water-depth data were collected using a Teledyne-Odom Echotrac CVM depth sounder coupled to a Global Positioning System...

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,...

This data release contains spatial data associated the sedimentation survey conducted by the U.S. Geological Survey cfor the Lago La Plata, Toa Alta, Puerto Rico, during March and April 2015 to provide up-to-date information about the relation of pool elevation and storage volume in the reservoir. The survey was conducted in cooperation with the Puerto Rico Aqueduct and Sewer Authority. A total of 264 navigation lines were surveyed, using a depth sounding device coupled to a global positioning system. The results of the survey were used to prepare a bathymetric map showing the reservoir bottom referenced with respect to the spillway elevation.

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 dataset is a polyline shapefile containing bathymetric contours, at 1-meter intervals, of Lago Guayabal, Villalba, Puerto Rico. The contours were generated from bathymetric data collected during a sedimentation survey conducted during the period December 11- December 14, 2017 by the Puerto Rico office of the Caribbean-Florida Water Science Center of the U.S. Geological Survey (USGS). The goals of the survey were to determine reservoir infill sedimentation rates, generate a bathymetric map of the reservoir, and create a stage-volume relation. Field techniques used during the survey were similar to those outlined by Soler-López (2008) and Wilson and Richards (2006). More than 270,000 water-depth points were surveyed...

This data release contains spatial data associated with the sedimentation survey of Lago Guayabal conducted during the period December 11- December 14, 2017 by the Puerto Rico office of the Caribbean-Florida Water Science Center (CFWSC) of the U.S. Geological Survey (USGS). The goals of the survey were to determine reservoir infill sedimentation rates, generate a bathymetric map of the reservoir, and create a stage-volume relation. Field data collection involved measuring water depth along predetermined navigation lines. More than 270,000 water-depth points were surveyed along 60 navigation lines and All water-depth data were collected using a Teledyne-Odom Echotrac CVM depth sounder coupled to a Global Positioning...

This dataset is a polygon shapefile containing reservoir boundary of Lago Guayabal, and represents the contour at the spillway elevation. This polygon was used to constraint the extent of the Triangulated irregular network (TIN) model and ultimately, to generate contours from bathymetric data collected during a sedimentation survey conducted during the period December 11- December 14, 2017 by the Puerto Rico office of the Caribbean-Florida Water Science Center of the U.S. Geological Survey (USGS). The goals of the survey were to determine reservoir infill sedimentation rates, generate a bathymetric map of the reservoir, and create a stage-volume relation.

This dataset contains the selected physical properties and chemical constituents that were measured at Puerto Mosquito, Isla de Vieques on June 22, 2017. A cross-sectional profile was conducted by measuring a total of ten selected site throughout the lagoon during the morning. Field water-quality measurements included the parameters of specific conductance, and dissolved oxygen.

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...
